| 1 | +# Quire Contributor License Agreement |
| 2 | + |
| 3 | +**Version:** 1.0 |
| 4 | +**Effective:** 2026-05-22 |
| 5 | + |
| 6 | +Thank you for contributing to Quire. This Contributor License Agreement |
| 7 | +("Agreement") documents the rights You grant to the maintainer of Quire so that |
| 8 | +Your contributions can be accepted, maintained, distributed, and — if needed in |
| 9 | +the future — licensed under AGPL-3.0-or-later for all or part of the Project, |
| 10 | +including the `server/` subtree. |
| 11 | + |
| 12 | +By signing this Agreement as described in Section 8, You agree to its terms for |
| 13 | +every Contribution You Submit to the Project, now and in the future, unless and |
| 14 | +until You withdraw the Agreement in writing to the maintainer. |
| 15 | + |
| 16 | +## 1. Definitions |
| 17 | + |
| 18 | +**"You"** means the individual submitting a Contribution. If You are submitting |
| 19 | +on behalf of a legal entity (e.g., as part of Your employment), "You" includes |
| 20 | +that entity, and You represent that You are authorized to bind it. |
| 21 | + |
| 22 | +**"We"** or **"Maintainer"** means Vito Fico, in his personal capacity as |
| 23 | +maintainer of Quire, and any successor, assignee, or legal entity that Vito |
| 24 | +Fico (or his estate) later designates in writing to own or maintain the |
| 25 | +Project. If maintainership is transferred, this Agreement transfers with it. |
| 26 | + |
| 27 | +**"Project"** means Quire, including the Android application, the Python |
| 28 | +server, and related documentation, tests, build files, assets, configuration, |
| 29 | +and infrastructure, in any branch or fork maintained by Us. |
| 30 | + |
| 31 | +**"Contribution"** means any code, documentation, test, configuration, asset, |
| 32 | +patch, pull request, or other copyrightable material that You intentionally |
| 33 | +Submit to Us for inclusion in the Project. A communication is not a |
| 34 | +Contribution if You clearly mark it "Not a Contribution." |
| 35 | + |
| 36 | +**"Submit"** means sending a Contribution to Us through GitHub, email, the |
| 37 | +issue tracker, source control, or another channel used by the Project. |
| 38 | + |
| 39 | +## 2. Copyright Grant |
| 40 | + |
| 41 | +You retain ownership of Your Contributions. |
| 42 | + |
| 43 | +You grant Us a perpetual, worldwide, non-exclusive, royalty-free, fully |
| 44 | +paid-up, irrevocable, transferable license, with the right to sublicense |
| 45 | +through multiple tiers, to use, reproduce, modify, prepare derivative works of, |
| 46 | +publicly display, publicly perform, distribute, and otherwise make available |
| 47 | +Your Contributions, alone or as part of the Project or works derived from the |
| 48 | +Project. |
| 49 | + |
| 50 | +## 3. Patent Grant |
| 51 | + |
| 52 | +If Your Contribution would otherwise infringe patent claims that You own or |
| 53 | +control, You grant Us a perpetual, worldwide, non-exclusive, royalty-free, |
| 54 | +fully paid-up, irrevocable, transferable patent license, with the right to |
| 55 | +sublicense through multiple tiers, to make, have made, use, sell, offer for |
| 56 | +sale, import, and otherwise transfer Your Contribution alone or as part of the |
| 57 | +Project or works derived from the Project. |
| 58 | + |
| 59 | +This patent license applies only to patent claims necessarily infringed by |
| 60 | +Your Contribution alone or by Your Contribution combined with the Project to |
| 61 | +which it was Submitted. |
| 62 | + |
| 63 | +## 4. Allowed Outbound Licenses |
| 64 | + |
| 65 | +We may license Your Contributions, and Project material containing Your |
| 66 | +Contributions, under either or both of: |
| 67 | + |
| 68 | +- the license or licenses that apply to the relevant Project material on the |
| 69 | + date You Submit the Contribution — currently Apache License 2.0 for the |
| 70 | + entire Project; and |
| 71 | +- GNU Affero General Public License version 3.0, or GNU Affero General Public |
| 72 | + License version 3.0 or any later version published by the Free Software |
| 73 | + Foundation ("AGPL-3.0-or-later"), for all or any part of the Project, |
| 74 | + including the `server/` subtree. |
| 75 | + |
| 76 | +This Agreement does not by itself change the Project's outbound license. Quire |
| 77 | +remains Apache-2.0 unless a file, subtree, or future release states otherwise. |
| 78 | +Section 4 only preserves Our option to relicense. |
| 79 | + |
| 80 | +## 5. Your Representations |
| 81 | + |
| 82 | +You represent that: |
| 83 | + |
| 84 | +- You have the legal authority to enter into this Agreement. |
| 85 | +- You own the rights needed to grant the licenses in this Agreement, or You |
| 86 | + have received permission from the rights holder to do so. |
| 87 | +- If You are contributing as part of Your employment or on behalf of a legal |
| 88 | + entity, You are authorized to Submit the Contribution under this Agreement |
| 89 | + and to bind that entity to it. |
| 90 | +- Your Contribution does not knowingly include third-party material unless |
| 91 | + that material is clearly identified and is provided under a license |
| 92 | + compatible with the Project's then-current licensing and with the outbound |
| 93 | + licenses listed in Section 4. |
| 94 | + |
| 95 | +## 6. No Obligation |
| 96 | + |
| 97 | +We are not required to accept, use, publish, or maintain any Contribution. |
| 98 | + |
| 99 | +## 7. Disclaimer |
| 100 | + |
| 101 | +Your Contributions are provided "AS IS", without warranties or conditions of |
| 102 | +any kind, including warranties of title, non-infringement, merchantability, or |
| 103 | +fitness for a particular purpose. |
| 104 | + |
| 105 | +## 8. Electronic Signature |
| 106 | + |
| 107 | +You sign this Agreement by commenting **exactly** the following text on a |
| 108 | +Quire pull request, in plain text (no quotes, no Markdown formatting): |
| 109 | + |
| 110 | +``` |
| 111 | +I have read the Quire Contributor License Agreement and I hereby sign the CLA |
| 112 | +``` |
| 113 | + |
| 114 | +Your signature is recorded by the Maintainer — currently via manual review of |
| 115 | +the PR comment thread before merge — and may be archived (GitHub username, user |
| 116 | +ID, PR number, commit SHA, timestamp) indefinitely for Project legal records. |
| 117 | +Pull request comments are public; the metadata above is already public via the |
| 118 | +comment itself. |
| 119 | + |
| 120 | +## 9. Versioning |
| 121 | + |
| 122 | +This is version 1.0 of the Quire CLA. If the Maintainer changes the CLA text |
| 123 | +materially, the version number will be incremented and a correspondingly |
| 124 | +versioned signature phrase will be adopted (e.g., "…version 2.0 of the Quire |
| 125 | +Contributor License Agreement…"), so previous signatures remain attached to |
| 126 | +the version of the CLA that was in force when they were given. |
