Privacy

subraum is built for data minimisation.

What does NOT happen

No audio/chat recording. Voice and text are peer-to-peer (DTLS-SRTP / encrypted DataChannel) and are stored nowhere.
No accounts, no login, no tracking, no ads, no tracking cookies.
The brokering server never sees media. Voice and chat never pass through it.

Signaling: to connect, the apps exchange connection data via the server (SDP/ICE candidates, chosen display name, room/session mapping). This lives only in memory and is dropped once the room is empty (within 24 h at most).
Session brokering: a random code + 6-digit PIN are held temporarily in memory (max 24 h) to let mates join without configuration.
Connection metadata: like any internet service the server technically sees IP addresses on connect; they are not persistently logged.
TURN relay (fallback only): if no direct path is possible, encrypted audio may pass through a relay. It forwards only encrypted bytes and cannot decrypt them.
Text size: picking a larger size on this site sets exactly one cookie, subraum_ui, holding nothing but md, lg or xl. It expires after a year, goes to nobody else and identifies no one. Without it the size resets on your next visit; browser zoom (Ctrl +) does the same job with no cookie at all.

Installers are served via GitHub Releases (GitHub's privacy terms apply to the download). STUN/TURN may use public STUN servers for NAT discovery.
