No. Fluxer doesn't ask contributors to sign a contributor license agreement (CLA) or to hand over their copyright, and you keep the copyright in your work. Fluxer is licensed under the GNU AGPL, version 3.0 or later, and your contributions use that same license.
What you agree to when you contribute
Each commit you send needs a Developer Certificate of Origin sign-off, which you add with git commit -s. The sign-off confirms you have the right to submit your change under the AGPL. The contributing guidelines list what else a pull request needs.
Why Fluxer had a CLA at first
When we opened Fluxer.app to everyone on January 2, 2026, we didn't know yet whether Fluxer could pay for itself. We wanted to keep the option of also offering Fluxer under a commercial license to organizations that couldn't follow the AGPL. That needed the right to relicense every contribution, so we added a CLA on January 5, 2026.
On February 9, 2026, a product decision by another chat app changed Fluxer's scope overnight, and it became clear that Fluxer could pay for itself without a second license. People on Reddit said that the CLA asked too much of contributors. Hampus removed the CLA on February 18, 2026, about six weeks after it had been added.
