Gearslip Contributor License Agreement
Version 1.0, October 2026
Thank you for contributing to Gearslip. This agreement lets Twink Software LLC, the company behind Gearslip, use your contribution. You keep the copyright in your work. You sign once, and the agreement covers every contribution you make to Gearslip, past and future.
Why we ask
Gearslip is free software under the GNU Affero General Public License, version 3 (the "AGPL"). Twink Software LLC also sells commercial licenses to companies that cannot meet the AGPL's terms, and that income helps pay for the project. Offering your code on those terms needs your permission, and this agreement gives it.
1. Definitions
- "We" and "us" mean Twink Software LLC, a California limited liability company (Secretary of State entity number B20260081700), under that name or any other, and its successors and assigns.
- "You" means the person who signs this agreement.
- "Contribution" means any work of authorship, such as code, documentation, or images, that you submit to Gearslip, whether before or after you sign. A submission includes a pull request, patch, or issue attachment sent to a repository or channel we manage. It excludes anything you mark in writing as "Not a Contribution".
2. Copyright license
You grant us, and anyone who receives software from us, a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute your Contributions and derivative works of them.
This license lets us offer your Contributions under licenses other than the AGPL, including commercial licenses.
3. Patent license
You grant us, and anyone who receives software from us, a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer your Contributions. This license covers only the patent claims you can license that your Contribution, alone or combined with Gearslip, would infringe.
If anyone sues claiming that Gearslip or a Contribution infringes a patent, the patent licenses granted to that party for Gearslip end on the date the suit is filed.
4. Our promise to you
As long as we distribute a Contribution, we will also offer it under the AGPL or another license approved by the Open Source Initiative. Your work will always stay available as free software.
5. Your promises
You promise that:
- The work is yours. Each Contribution is your original creation, and you have the right to grant these licenses.
- Your employer agrees. If your employer has rights in what you create, you have its permission to contribute on its behalf, or it has waived its rights in your Contributions.
- You name other people's work. If any part of a Contribution is not your own, you say so when you submit it, and you name its source and its license.
- You'll tell us of changes. If any of these promises stops being true, you will tell us.
6. No warranty
You provide your Contributions "as is", without warranties or conditions of any kind. You do not have to provide support for them.
7. No obligation
We are not required to use or include any Contribution.
8. General
- California law governs this agreement.
- This agreement does not change the rights you have under the AGPL in Gearslip as released.
- We may publish a new version of this agreement. A new version applies only to Contributions you make after you sign it; this version keeps covering the ones you made under it.
