Slint Software License

Version 3.0.2

Preamble

Slint is a toolkit that can be used to build user interfaces for applications. Slint (hereafter referred to as Software) is made available under different licenses by SixtyFPS GmbH incorporated at Oranienburger Str. 44, 16540 Hohen Neuendorf, Germany (SixtyFPS). The Slint Software License is suitable for those who do not want to use open source components under copyleft licenses.

1. Grant of Rights

SixtyFPS hereby grants You a world-wide, non-exclusive license to use, reproduce, make available, modify, display, perform, distribute the Software as part of a Desktop, Mobile, or Web Application or as part of an Embedded System (each of which is defined below).

A Desktop Application is a computer program that is designed to run on a general-purpose computer (PC or notebook), typically installed and executed locally on the computer's operating system.

A Mobile Application is a computer program that is designed to run on a general-purpose mobile computer (mobile phone or tablet), typically installed and executed locally on the computer's operating system.

A Web Application is a computer program that is designed to run in the sandbox environment provided by a web browser.

An Embedded System is a computer system designed to perform a specific task within a larger mechanical or electrical system.

Desktop Application, Mobile Application, and Web Application are hereafter referred to as Application.

2. License Conditions

The grant of rights in section 1 are conditional, provided that You do all of the following:

(a) You have purchased an appropriate Paid License Plan (see Annex 1) and the required amount of seats to cover all individual users of the Software associated with the designing, developing, or testing your Application or Embedded System. For clarity, each individual user is counted as one seat.

(b) In the case that You are distributing the Software as as part of an Embedded System, You have purchased an appropriate quantity of Royalties, one Royalty for each Embedded System. Royalties are not necessary for non-commercial projects, personal projects, and open source projects.

3. Limitations

The License does not permit to distribute or make the Software publicly available alone and without integration into an Application or into an Embedded System. For this purpose you may use the Software under the GNU General Public License, version 3.

The License is limited to only the versions of Software that were made available to you under the purchased Pricing Plan. For all other versions, you may use the Software under either the GNU General Public License, version 3 or the Slint Royalty-free Desktop, Mobile, and Web Applications License.

The License does not permit the distribution of Application that exposes the APIs, in part or in total, of the Software.

You may not remove or alter any license notices (including copyright notices, disclaimers of warranty, or limitations of liability) contained within the source code form of the Software.

4. Audit Rights

SixtyFPS or an independent certified auditor on SixtyFPS's behalf, may, upon its reasonable request, with 30 (thirty) days written notice, and at its sole expense, examine your books and records solely with respect to your use of the Software. Any such audit shall be conducted during regular business hours at your facilities and shall not unreasonably interfere with your business activities. The auditor shall not remove, copy, or redistribute any electronic material during an audit. If an audit reveals that you are using the Software in a way that is in material violation of the terms of this License, then you shall pay SixtyFPS reasonable costs of conducting the audit. The auditor shall only be allowed to report violations of the terms of this License, with a copy to you. You shall be provided the right to provide comments to the report before it is finalized.

5. Termination

(a) SixtyFPS may terminate this License if You materially breach any obligation hereunder, provided You have been provided notice of such breach and an opportunity to cure such breach during a period of not less than sixty (60) days following such notice.

(b) You may terminate this License with or without cause upon no less than thirty (30) days advance written notice to SixtyFPS.

(c) Upon termination of this License, You will immediately cease using, reproducing, making available, modifying, displaying, performing, distributing the Software and pay immediately any unpaid Fees and contractual penalties.

(d) Sections 3 through 8 of this License will survive any termination of the License to the extent necessary to implement their objectives.

6. Assignment

You may assign this License, in whole or in part (whether by operation of law or otherwise), with prior consent from SixtyFPS, which shall not be unreasonably withheld or delayed. SixtyFPS may assign any of its rights hereunder or delegate any of its obligations hereunder with prior notice to You. Any attempt to assign this License other than in accordance with this Section 6 shall be null and void.

7. Severability

In the event that any provision of this License will, for any reason, be determined by any court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will be interpreted as closely as possible so as not affect any other provision of this License, and such provision will further be modified by said court to permit its enforcement to the maximum extent permitted by law.

8. Governing Law

This Agreement shall be construed, interpreted, and governed by the laws of the Federal Republic of Germany.

GPL 3.0

GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. https://fsf.org/

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.

To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.

For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.

Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.

Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS

0. Definitions.

"This License" refers to version 3 of the GNU General Public License.

"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.

"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.

To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.

A "covered work" means either the unmodified Program or a work based on the Program.

To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.

To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.

An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

1. Source Code.

The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.

A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.

The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.

The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.

The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

2. Basic Permissions.

All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.

You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.

Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.

No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.

When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.

4. Conveying Verbatim Copies.

You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.

You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.

5. Conveying Modified Source Versions.

You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:

  • a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
  • b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
  • c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
  • d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.

A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

6. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:

  • a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
  • b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
  • c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
  • d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
  • e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.

A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.

"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.

If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).

The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.

7. Additional Terms.

"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.

When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.

Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:

  • a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
  • b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
  • c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
  • d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
  • e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
  • f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.

All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.

If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.

Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.

8. Termination.

You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).

However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.

9. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.

10. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.

An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.

11. Patents.

A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".

A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.

In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.

If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.

12. No Surrender of Others' Freedom.

If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.

13. Use with the GNU Affero General Public License.

Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.

14. Revised Versions of this License.

The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.

If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.

Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.

15. Disclaimer of Warranty.

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

16. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.

If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.

Also add information on how to contact you by electronic and paper mail.

If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:

    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".

You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see https://www.gnu.org/licenses/.

The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read https://www.gnu.org/licenses/why-not-lgpl.html.

Version 2.0

This Slint Premium Support Services Agreement (Agreement) is made by and between SixtyFPS GmbH with offices at Oranienburger Str. 44, 16540 Hohen Neuendorf, Germany (SixtyFPS) and the party clicking through to accept this Agreement (You or Customer).

2. Retention

Customer hereby retains SixtyFPS to provide the Consulting Services described on one or more SOWs, subject to the terms and conditions set forth in this Agreement. The terms and conditions of this Agreement will govern the provision of Consulting Services under any SOW (including any exhibits thereto) executed by the Parties.

(c) SixtyFPS will perform the Consulting Services, directly or through a Subcontractor of its choice. Customer agrees to provide, at no cost to SixtyFPS, timely and adequate assistance and other resources reasonably requested by SixtyFPS to enable the performance of the Consulting Services by SixtyFPS (collectively, Assistance).

(d) In performing the Consulting Services, SixtyFPS will provide such resources, and utilize such qualified employees and/or non-employee contractors of SixtyFPS (Subcontractors and together with SixtyFPS's employees, Personnel) as it deems necessary to perform the Consulting Services or any portion thereof. Customer may object to SixtyFPS's election of Subcontractors by specifying its objection to SixtyFPS, in which case the Parties will cooperate in good faith to appoint another Subcontractor to perform such Consulting Services. SixtyFPS may replace Personnel in its normal course of business, provided that SixtyFPS will be responsible for the performance of Consulting Services by all Personnel.

(e) SixtyFPS will control the method and manner of performing all work necessary for completion of Consulting Services, including but not limited to the supervision and control of any Personnel performing Consulting Services. SixtyFPS will maintain such number of qualified Personnel and appropriate facilities and other resources sufficient to perform SixtyFPS's obligations under this Agreement in accordance with its terms.

4. Rights to Deliverables; Ownership

(a) Each Party reserves and retains ownership to all of the respective Party's inventions (whether or not patentable), works of authorship, designs, know-how, ideas, concepts, information and tools in existence prior to the commencement of the Consulting Services (Preexisting Technology) and no Preexisting Technology shall be delivered nor any right or license to such Preexisting Technology shall be assigned or granted to the other Party hereunder.

(b) Subject to Section 4.(d), Customer shall retain all right, title and interest in any deliverable expressly stated in an SOW to be a Work Made for Hire.

(c) Unless otherwise expressly specified in a SOW, no deliverable provided in connection with the Consulting Services provided pursuant to this Agreement shall constitute a “Work Made For Hire” under this Agreement.

(d) Without limiting the foregoing, SixtyFPS and its licensors reserves and retains ownership to all Developed Technology and Generic Components (each as defined here). Developed Technology means ideas (whether or not patentable) know-how, technical data, techniques, concepts, information or tools, and all associated intellectual property rights thereto developed by SixtyFPS or its Personnel in connection with providing Consulting Services pursuant to this Agreement that derive from, improve, enhance or modify SixtyFPS's Preexisting Technology.

(a) Customer will pay SixtyFPS the fees to provide the Consulting Services as detailed or described in an SOW (Fees).

Any amended T&M Estimate which is or is deemed accepted by Customer shall be deemed a Change Order.

(c) The performance of Consulting Services may be subject to a retainer to be paid in advance by Customer upon execution and delivery of the SOW. Such retainer will be applied against Fees which become payable by Customer pursuant to this Agreement. SixtyFPS may refuse to perform Consulting Services unless and until such retainer is paid to SixtyFPS.

(d) In addition to any and all Fees, Customer will reimburse SixtyFPS for the reasonable expenses for travel, lodging, communications, shipping charges and out-of-pocket expenses incurred by SixtyFPS in connection with providing the Consulting Services (Expenses). SixtyFPS will provide reasonable documentation for all Expenses as requested by Customer.

This Agreement will not be construed so as to create a partnership, other joint venture or undertaking, or any agency relationship between the Parties, and neither Party shall become liable for any representation, act or omission of the other Party or have the authority to contractually bind the other Party. Any Fees, Expenses or other amounts paid by Customer to SixtyFPS hereunder shall not be considered salary for pension or wage tax purposes and neither SixtyFPS nor its Personnel will be entitled to any fringe benefits, including sick or vacation pay, or other supplemental benefits of Customer, Unless otherwise required by law, Customer shall not be responsible for deducting or withholding from Fees or Expenses paid under this Agreement any taxes, unemployment, social security or other such expense.

7. Term and Termination

(a) This Agreement will commence on the Effective Date and will remain effective for as long as any SOW is in effect among the Parties, unless terminated earlier in accordance with the terms of this Section 7. Any termination of this Agreement shall terminate any then-effective SOW.

(b) This Agreement may be terminated by either Party with or without cause upon no less than thirty (30) days advance written notice to the other Party.

(c) Either Party may terminate this Agreement if the other Party materially breaches any obligation hereunder, provided the terminating Party has provided notice of such breach to the other Party and an opportunity to cure such breach during a period of not less than thirty (30) days following such notice.

(d) Upon termination of this Agreement, SixtyFPS will immediately cease performing any Consulting Services, and Customer will pay SixtyFPS any Fees not yet paid for all Consulting Services provided pursuant to any SOW on or prior to such termination on a pro-rated basis (or on such other basis as the Parties will mutually agree) and reimburse Expenses incurred on or prior to termination not yet reimbursed.

(e) Sections 4 through 14 of this Agreement will survive any termination of the Agreement to the extent necessary to implement their objectives. Termination of this Agreement will be without prejudice to other rights or remedies of any Party under this Agreement or applicable law, including, without limitation, any remedies for a breach of this Agreement prior to such termination.

8. Warranties, Limitation of Liability

(a) SixtyFPS hereby represents and warrants that:

i. it has all authority, licenses, permits, and consents necessary to enter into and perform its obligations under this Agreement, and will fully comply with all applicable laws and regulations in performing the Consulting Services;

ii. the Consulting Services provided pursuant to this Agreement will be performed in a timely and professional manner by SixtyFPS and its Personnel, consistent with generally-accepted industry standards; provided that Customer's sole and exclusive remedy for any breach of this warranty will be, at SixtyFPS's option, re-performance of the Consulting Services or termination of the applicable SOW and return of the portion of the Fees paid to SixtyFPS by Customer for the non-conforming portion of the Consulting Services; and

iii. it is under no contractual or other restrictions or obligations which are inconsistent with the execution of this Agreement, or, to its best knowledge, which will interfere with its performance of the Consulting Services.

(b) The Parties hereby agree that:

i. Except as expressly set forth in this section 8, SixtyFPS expressly disclaims to the fullest extent allowed by applicable law all other representations and warranties, express or implied, including, without limitation, any implied warranties or conditions of merchantability, fitness for a particular purpose, accuracy, non-satisfactory quality, non-infringement of third party rights and title, or arising from a course of dealing, usage, or trade practice, and all such representations and warranties are hereby excluded to the fullest extent allowed by applicable law.

ii. These disclaimers and exclusions will apply even if the express warranty and limited remedy set forth above fails of its essential purpose.

(c) Under no circumstances and under no legal theory (whether in contract, tort, negligence or otherwise) will either Party to this Agreement, or their affiliates, officers, directors, employees, agents, suppliers or licensors be liable to the other Party or any third party for any indirect, incidental, special, exemplary, consequential, punitive or other similar damages, including lost profits, lost sales or business, business interruption or any other loss incurred by the other Party or such third party in connection with this Agreement or the Consulting Services, regardless of whether a Party has been advised of the possibility of or could have foreseen such damages.

(d) Each Party's aggregate liability arising out of this Agreement or otherwise in connection with any Consulting Services, shall in no event exceed the fees paid by Customer prior to the first event or occurrence giving rise to such liability. Each Party acknowledges and agrees that the essential purpose of this para is to allocate the risks under this Agreement between the Parties and limit potential liability given the Fees, which would have been substantially higher if SixtyFPS were to assume any further liability other than as set forth herein. SixtyFPS has relied on these limitations in determining whether to provide Customer the Consulting Services provided for in this Agreement.

(e) Some jurisdictions do not allow the exclusion of implied warranties or limitation of liability for incidental or consequential damages, which means that some of the above limitations may not apply. In these jurisdictions, each Party's liability will be limited to the greatest extent permitted by law.

9. Recruitment Restriction

(a) Neither Party may actively solicit for employment any individual employed by the other Party who has actively participated in the performance of Consulting Services under this Agreement, until twelve (12) months have passed from the termination or expiration of the relevant Consulting Services.

(b) In case of a breach of the recruitment restriction specified in section 9.1, the Party in breach shall be liable to pay to the other Party in liquidated damages an amount corresponding to six (6) months brutto salary of the individual concerned.

(c) The recruitment restriction shall not be applied if the employment of the individual in question has been terminated due to a reason attributable to the employer.

10. Entire Agreement

This Agreement constitutes the complete agreement between the Parties and supersedes all prior or contemporaneous discussions, representations, and proposals, written or oral, with respect to the subject matters discussed herein. No modification of this Agreement will be effective unless contained in a written document executed by an authorized representative of each Party. If any provision of the Agreement is found void or unenforceable, the remainder will remain valid and enforceable according to its terms. If any remedy provided is determined to have failed for its essential purpose, all limitations of liability and exclusions of damages set forth in this Agreement shall remain in effect.

No change, modification or waiver to this Agreement will be effective unless in writing and signed by both Parties.

11. Severability

In the event that any provision of this Agreement will, for any reason, be determined by any court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will be interpreted as closely as possible so as not affect any other provision of this Agreement, and such provision will further be modified by said court to permit its enforcement to the maximum extent permitted by law.

12. Governing Law

This Agreement shall be construed, interpreted, and governed by the laws of the Federal Republic of Germany.
