RelayMic is open source under the GNU AGPL-3.0. That license is the real agreement; everything below is it in plain words.
What you may do
Run it, study it, change it, and share it — including commercially. You do not need anyone's permission and you owe nothing.
What you owe in return
If you distribute a modified version, or let other people use one over a network, you have to give those people the complete source of your version, under this same license. That second half is what makes it AGPL rather than plain GPL: running a modified copy on a server counts, even if you never hand out a binary.
In practice: use it however you like, privately, forever. But you cannot take this code, build a closed-source product on top, and keep those changes to yourself. If that is what you need, write to me — a separate commercial license is negotiable, and I hold the copyright to grant one.
What is not promised
The software is provided as is, with no warranty of any kind. Audio quality and latency depend on networks nobody here controls. It is built for speech — calls, dictation, meetings — and is not represented as suitable for professional music monitoring, medical use, emergency communication, or any situation where a dropped connection causes harm.
It is one developer's working tool, opened up. There is no support obligation, no uptime commitment, and no promise that any particular version will keep working.
What you are responsible for
Installing software on machines you are allowed to install software on. RelayMic asks you to install a third-party open-source audio driver (BlackHole) from its official package; that project has its own license and its own authors.
Also: whatever you say into it. A microphone that reaches another building is still a microphone — know which applications on the far end are listening.
This website
Provided as is, collects nothing (see Privacy), and exists mainly to point at the repository.
