Version 1.0 — 23 July 2026
Thank you for contributing to RememberStack. This Contributor License Agreement ("Agreement") documents the rights that You grant to WriteIt.ai s.r.o., IČO 04518136, with its registered office at Na Folimance 2155/15, Vinohrady, 120 00 Praha 2, Czech Republic ("We", "Us", or "WriteIt.ai").
This is a legally binding agreement. You accept it electronically when You submit a RememberStack pull request containing the checked assent required by the repository's pull-request template. If You do not agree, do not check that box or submit the work for inclusion.
"You" means the authenticated GitHub pull-request author accepting this Agreement as an individual. If that author identifies a legal entity in the pull request's "Signing on behalf of" field, "You" instead means that entity and the author represents that they are authorized to bind it.
"Contribution" means a work of authorship that You Submit to Us for inclusion in RememberStack and in which You own, or have authority to license, the applicable Copyright. It excludes material conspicuously marked "Not a Contribution" and third-party material that You identify as such.
"Copyright" means copyright, moral, neighboring, and similar rights protecting works of authorship for the full term of those rights.
"Material" means RememberStack and any successor, renamed, split, combined, or derivative project controlled by Us into which Your Contribution is incorporated.
"Submit" means intentionally sending a Contribution to a repository, issue tracker, or other collaboration system managed by Us for the purpose of discussing or improving the Material.
"Self-Host" means to install and operate the Material, in source or object form and with or without modification, on infrastructure selected or controlled by the recipient for that recipient's own use. It includes personal, research, nonprofit, and internal commercial production use. It does not include offering the Material's functionality to third parties as a hosted or managed service.
"Qualifying License" means a license under which every recipient has perpetual rights, without paying a license fee to Us or an affiliate and without being required to purchase support or another service, to:
- obtain the corresponding source code for the Material;
- reproduce and modify the Material;
- redistribute the Material and modifications, in source or object form, for others to Self-Host; and
- Self-Host and operate the Material without limits based on users, seats, instances, data volume, or duration.
A Qualifying License may require attribution, publication of modifications, source-code availability, or other reciprocal conditions. It may also restrict offering the Material as a hosted or managed service to third parties. Charges for hosting, support, consulting, or other services do not by themselves prevent a license from qualifying.
You retain ownership of the Copyright in Your Contribution and remain free to use or license it independently.
To the maximum extent permitted by law, You grant Us a perpetual, worldwide, non-exclusive, transferable (subject to Section 6.3), royalty-free, irrevocable copyright license, with the right to sublicense through multiple tiers, to reproduce, modify, prepare derivative works of, publicly display, publicly perform, distribute, and otherwise use Your Contribution as part of the Material.
For patent claims that You own, control, or have the right to license now or in the future, You grant Us a perpetual, worldwide, non-exclusive, transferable (subject to Section 6.3), royalty-free, irrevocable patent license, with the right to sublicense through multiple tiers, to make, have made, use, offer to sell, sell, import, and otherwise transfer Your Contribution and Your Contribution in combination with the Material.
This license applies only to claims necessarily infringed by Your Contribution alone or by its combination with the Material.
We covenant that, when We license Your Contribution to third parties as part of the Material, We will do so only under one or more Qualifying Licenses. The Apache License, Version 2.0 used by RememberStack on the date of this Agreement is a Qualifying License.
This covenant permits a future license to protect a hosted-service business, but it does not permit Us to remove the source-availability and free Self-Hosting rights defined above. Once We release a version under a Qualifying License, We will not revoke or narrow the rights already granted under that license. Versions already released under the Apache License, Version 2.0 remain available under that license.
This covenant does not restrict Our use of the Contribution, including using it to provide hosted services without granting third parties a copyright license to the Material. It does not require Us to publish a Contribution that We have not incorporated into the Material.
The grants in Sections 2.1 and 2.2 are not conditional on this covenant and do not terminate automatically if We breach it. A breach of this Section 2.3 is a material breach of this Agreement. You may seek injunctive relief, specific performance, and any other remedy available under applicable law to stop or remedy licensing that violates this covenant. A breach does not invalidate a license previously granted to a recipient under a Qualifying License.
To the maximum extent permitted by law, You waive and agree not to assert moral rights in the Contribution against Us, Our successors, or Our direct or indirect licensees. Where waiver is not permitted, You grant the broadest license or consent permitted by law to exercise those rights consistently with this Agreement.
You reserve every right not expressly granted by this Agreement. We are not required to accept or use any Contribution.
You represent that:
- You have legal authority to enter into this Agreement and make these grants.
- The Contribution is Your original work, or You otherwise own or control the rights needed to grant the licenses in Section 2.
- These grants do not violate an agreement with another party, including Your employer. If another person or entity owns or controls the relevant rights, You have obtained its authorization before Submitting.
- You have identified any third-party material included in the Contribution and complied with its license. Material You do not have authority to license under this Agreement must be clearly marked "Not a Contribution."
- The Contribution is not confidential information that You or another party expects Us to keep confidential.
- If You are accepting for a legal entity, You are authorized to bind that entity. If You are under the age required to enter this Agreement, Your parent or legal guardian has accepted it for You.
EXCEPT FOR THE EXPRESS REPRESENTATIONS IN SECTION 3, THE CONTRIBUTION IS PROVIDED "AS IS". TO THE MAXIMUM EXTENT PERMITTED BY LAW, YOU DISCLAIM ALL EXPRESS OR IMPLIED WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER YOU NOR WE WILL BE LIABLE TO THE OTHER UNDER THIS AGREEMENT FOR LOST PROFITS, LOST SAVINGS, LOSS OF DATA, OR INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL, OR EXEMPLARY DAMAGES, REGARDLESS OF THE THEORY OF LIABILITY.
This Agreement is governed by the laws of the Czech Republic, excluding its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
This Agreement is the entire agreement between You and Us concerning Your Contributions and supersedes prior understandings about those Contributions.
We may transfer this Agreement and the rights granted under it to an affiliate or to a successor or acquirer of all or substantially all of the Material or the business that maintains it, but only if that recipient agrees in writing to assume Our obligations, including Section 2.3. You may transfer this Agreement only with Our written consent. Existing Qualifying Licenses and permitted sublicenses remain effective after a transfer.
A failure to enforce a provision is not a waiver of that provision. If a provision is unenforceable, it will be adjusted only as far as necessary to make it enforceable while preserving its intent; the remaining provisions stay effective.
Each published revision of this Agreement has a version number. A revision applies only to Contributions for which You assent to that revision; it does not retroactively expand grants made under an earlier version.
Your authenticated GitHub account, the pull request containing Your checked assent and any "Signing on behalf of" entry, and GitHub's associated repository history form the electronic record of Your acceptance.
This Agreement is adapted from the Harmony Contributor Agreement Template, Version 1.0, licensed under CC BY 3.0. It has been materially modified for RememberStack, including its bounded outbound-license condition, electronic acceptance, and Czech governing law. Project Harmony does not endorse this Agreement.
