Anonymous by default. Honest about the machinery.

0° does not use accounts, friends lists, saved profiles, or persistent room history. Your session name is temporary and changes across sessions.

What We Store

Pending thoughts for matching, usually for about five minutes.
Match handoff data for about two minutes so both people can enter the same room and exchange ephemeral public keys.
Encrypted WebSocket relay envelopes while both people are connected.
Short-lived encrypted fallback chat payloads for about thirty minutes when the live relay is unavailable.
Minimal abuse report metadata for about thirty days.

What We Do Not Store

No account profile.
No friends graph.
No permanent conversation archive.
No broker-generated room message secret.
No readable chat text in fallback message storage.
No raw tokens or secrets in logs.

Reports

When you report a room, we store the reason, room hash, reporter session hash, mode, title, rough request metadata, and timestamp. We do not copy the full chat transcript into the report.
