To make this document effective, please follow the instructions at https://github.com/NihilDigit/piko/blob/main/CONTRIBUTING.md. ### How to use this Contributor Agreement If You are an employee and have created the Contribution as part of your employment, You need to have Your employer approve this Agreement. If You do not own the Copyright in Your Contribution, any other author of the Contribution should also sign this. In any event, please contact Us at nihildigit@outlook.com. ### Definitions **"You"** means the individual Copyright owner who Submits a Contribution to Us; or if the Copyright in the Contribution is held by a Legal Entity and the Contribution is being Submitted to Us on behalf of such Legal Entity, "You" means such Legal Entity. **"Contribution"** means any original work of authorship, including any original modifications or additions to an existing work of authorship, Submitted for inclusion into Material by You to Us, in which you own the Copyright. **"Copyright"** means all rights protecting works of authorship, including copyright, moral and neighboring rights, as appropriate, for the full term of their existence. **"Material"** means the software and/or documentation of Piko that we make available to third parties. When this Agreement covers more than one software project, the Material means the software or documentation to which the Contribution was Submitted. After You Submit the Contribution, it may be included in the Material. **"Submit"** means any act by which a Contribution is transferred to Us by You by means of tangible or intangible media, including but not limited to electronic mailing lists, source code control systems, and issue tracking systems, but excluding any transfer that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution." **"Documentation"** means any non-software portion of a Contribution. ### License grant #### Copyright license to Us Subject to the terms and conditions of this Agreement, You hereby grant to Us a worldwide, royalty-free, NON-exclusive, perpetual and irrevocable (except as stated in Section "Term") license, with the right to transfer an unlimited number of non-exclusive licenses or to grant sublicenses to third parties, under the Copyright covering the Contribution to use the Contribution by all means, including, but not limited to: - publish the Contribution, - modify the Contribution, - prepare derivative works based upon or containing the Contribution and/or to combine the Contribution with other Materials, - reproduce the Contribution in original or modified form, - distribute, to make the Contribution available to the public, display and publicly perform the Contribution in original or modified form. #### Moral rights Moral Rights remain unaffected to the extent they are recognized and not waivable by applicable law. Notwithstanding, You may add your name to the attribution mechanism customary used in the Materials you Contribute to, such as the header of the source code files of Your Contribution, and We will respect this attribution when using Your Contribution. ### Patents #### Patent license Subject to the terms and conditions of this Agreement You hereby grant to Us and to recipients of Materials distributed by Us a worldwide, royalty-free, non-exclusive, perpetual and irrevocable (except as stated in Subsection "Revocation of patent license") patent license, with the right to transfer an unlimited number of non-exclusive licenses or to grant sublicenses to third parties, to make, have made, use, sell, offer for sale, import and otherwise transfer the Contribution and the Contribution in combination with any Material (and portions of such combination). This license applies to all patents owned or controlled by You, whether already acquired or hereafter acquired, that would be infringed by making, having made, using, selling, offering for sale, importing or otherwise transferring of Your Contribution(s) alone or by combination of Your Contribution(s) with any Material. #### Revocation of patent license You reserve the right to revoke the patent license stated in Subsection "Patent license" if We make any infringement claim that is targeted at your Contribution and not asserted for a Defensive Purpose. An assertion of claims of the Patents shall be considered for a "Defensive Purpose" if the claims are asserted against an entity that has filed, maintained, threatened, or voluntarily participated in a patent infringement lawsuit against Us or any of Our licensees. ### License obligations by Us We may, but are under no obligation to, include the Contribution You Submitted to Us into the Material. We agree to license the Contribution only under the terms of the following license(s) the GNU Affero General Public License v3.0 or any later version (AGPL-3.0-or-later), and in addition any other license, including proprietary licenses, provided that the Contribution remains available under AGPL-3.0-or-later (including any right to adopt any future version of a license if permitted), whereby any non-free or non-open licenses need to be listed as well. We agree to license patents owned or controlled by You only to the extent necessary to (sub)license Your Contribution(s) and the combination of Your Contribution(s) with the Material under the terms of the following the GNU Affero General Public License v3.0 or any later version (AGPL-3.0-or-later), and in addition any other license, including proprietary licenses, provided that the Contribution remains available under AGPL-3.0-or-later license(s). ### Disclaimer **We acknowledge that you provide the Contribution "as is".** **More particularly, You disclaim all express or implied warranties including, without limitation, any implied warranty of satisfactory quality, fitness for a particular purpose and non-infringement. To the extent that any such warranties cannot be disclaimed, such warranty is limited in duration and extent to the minimum period and extent permitted by law.** ### Consequential damage waiver **To the maximum extent permitted by applicable law, in no event will You or We be liable for any loss of profits, loss of anticipated savings, loss of data, indirect, special, incidental, consequential and exemplary damages arising out of this Agreement regardless of the legal or equitable theory (contract, tort or otherwise) upon which the claim is based.** ### Approximation of disclaimer and damage waiver **If the disclaimer and damage waiver mentioned in Subsection "Disclaimer of warranty" and Section "Consequential damage waiver" cannot be given legal effect under applicable local law, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil or contractual liability in connection with the Contribution.** ### Term This Agreement shall come into effect upon Your acceptance of the terms and conditions. This Agreement shall apply for the term of the copyright and patents licensed here. However, You shall have the right to terminate the Agreement if We do not fulfill the obligations as set forth in Section "License obligations by Us". Such termination must be made in writing. In the event of a termination of this Agreement Sections "Disclaimer", "Term" and "Miscellaneous" shall survive such termination and shall remain in full force thereafter. For the avoidance of doubt, Free and Open Source Software (sub)licenses that have already been granted for Contributions at the date of the termination shall remain in full force after the termination of this Agreement. ### Miscellaneous This Agreement and all disputes, claims, actions, suits or other proceedings arising out of this agreement or relating in any way to it shall be governed by the laws of the People's Republic of China (for the purpose of this Agreement, excluding the Hong Kong SAR, the Macao SAR and Taiwan) excluding its private international law provisions. This Agreement sets out the entire agreement between You and Us for Your Contributions to Us and overrides all other agreements or understandings. In case of Your death, this agreement shall continue with Your heirs. In case of more than one heir, all heirs must exercise their rights through a commonly authorized person. If any provision of this Agreement is found void and unenforceable, such provision will be replaced to the extent possible with a provision that comes closest to the meaning of the original provision and that is enforceable. The terms and conditions set forth in this Agreement shall apply notwithstanding any failure of essential purpose of this Agreement or any limited remedy to the maximum extent possible under law. You agree to notify Us of any facts or circumstances of which you become aware that would make Your representations under this Agreement inaccurate in any respect.
