Contributor License Agreement ("CLA")

Thank you for your interest in contributing to SFTPGo, its plugins, SDK and related software. This page describes the established guidelines for contributions.

Requiring a CLA is a common and well-accepted practice in open source. Agreeing to the CLA explicitly states that you are entitled to provide a contribution and that you cannot withdraw permission to use your contribution at a later date. This removes any ambiguities or uncertainties.

Every contributor of non-trivial amounts of code to SFTPGo or any of its related projects should sign such a document. If somebody is unable to sign the document, their contribution may need to be removed from SFTPGo.

Open a pull request ("PR") to SFTPGo or any of its related projects to sign the CLA. A bot will comment on the PR asking you to sign the CLA if you haven't already.

Follow the steps given by the bot to sign the CLA. This will require you to log in with GitHub (we only request public information from your account) and to fill in a few additional details such as your name and email address. We will only use this information for CLA tracking; none of your submitted information will be used for marketing purposes.

You only have to sign the CLA once. Once you've signed the CLA, future contributions will not require you to sign again, you just need to confirm that you have read and agree with this CLA.

In order to clarify the intellectual property license granted with Contributions from any person or entity, the SFTPGo author Nicola Murino must have a Contributor License Agreement ("CLA") on file that has been signed by each Contributor, indicating agreement to the license terms below. This license is for your protection as a Contributor as well as the protection of SFTPGo and its users; it does not change your rights to use your own Contributions for any other purpose.

All past and future contributors to SFTPGo are required to accept these terms. If somebody is unable to sign the document, their contribution will not be accepted or will be removed or rewritten.

You accept and agree to the following terms and conditions for all Your present, past and future Contributions that you submit to SFTPGo. Except for the license granted herein to Nicola Murino and recipients of SFTPGo, You reserve all right, title, and interest in and to Your Contributions.

1. Definitions. "You" (or "Your") shall mean the copyright owner or legal entity authorized by the copyright owner that is making this Agreement with Nicola Murino. For legal entities, the entity making a Contribution and all other entities that control, are controlled by, or are under common control with that entity are considered to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. "Contribution" shall mean any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Nicola Murino for inclusion in, or documentation of, any of the products owned or managed by Nicola Murino (the "Work"). For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Nicola Murino, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Nicola Murino for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."
2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Nicola Murino and to recipients of software distributed by Nicola Murino a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright and/or intellectual property license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works.
3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Nicola Murino and to recipients of software distributed by Nicola Murino a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
4. You represent that you are legally entitled to grant the above license. If your employer(s) has rights to intellectual property that you create that includes your Contributions, you represent that you have received permission to make Contributions on behalf of that employer, that your employer has waived such rights for your Contributions to the SFTPGo, or that your employer has executed a separate Corporate CLA with Nicola Murino.
5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of others). You represent that Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) and which are associated with any part of Your Contributions.
6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON- INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
7. Should You wish to submit work that is not Your original creation You may submit it to the SFTPGo separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
8. You agree to notify Nicola Murino of any facts or circumstances of which you become aware that would make these representations inaccurate in any respect.
