What this website collects

One thing: visit statistics, through Google Analytics — which pages get opened, roughly where visitors come from, and how they found the site. It sets a cookie to tell returning browsers apart. That is the only third-party script on the site, and this paragraph exists because it was added; earlier versions of this page said "nothing at all", and the change is visible in the site's public git history, as promised below.

There is still no account to create, no email to leave, no form, and no database behind this page. The fonts are served from this domain. If you block the analytics script, everything on the site works exactly the same.

Your audio

This is the part most people are actually asking about.

RelayMic carries audio directly between your browser and your Mac over an encrypted peer-to-peer connection. When two networks cannot reach each other directly, it falls back to a TURN relay — one that you configure and control. There is no server of ours anywhere in that path.

That is a stronger statement than a promise not to look: we could not look if we wanted to, because nothing of ours is in the way. And you do not have to take our word for any of it — the code is public. Read it. That is the point of open-sourcing a tool that handles your voice.

The diagnostic recordings you may have read about are a local feature: they are written to your own Mac, stay there, and are yours to delete.

Who is behind this

RelayMic is written by Shu Chunhui, an individual developer based in Shanghai, China, reachable at hey@relaymic.com.

If you email that address, your message obviously reaches a person — that is the only way any personal data of yours ends up with us, and only because you chose to send it. It is not added to any list.

Changes

If this ever stops being true, this page changes first, and the change is visible in the site's public git history.
