Terms of Service
Last updated: March 2026
What this is
O-O is a video chess app. You play chess over live video with friends or strangers. The video is peer-to-peer — it goes directly between you and your opponent.
Age requirement
You must be 18 or older to use the matchmaking feature (playing with strangers). Friend games and local games have no age restriction.
Expected behavior
Be a decent human. No nudity, no harassment, no hate speech, no threats. This is a chess game, not a place to be awful. If someone reports you, we'll review it and may revoke your access.
Reporting
You can report your opponent during or after a game. Reports are logged and may be acted on. Repeated reports against the same player may result in restricted access.
The service
O-O is provided as-is. We can change, pause, or shut down the service at any time. We can terminate access for anyone who violates these terms.
Privacy Policy
Video & audio
Your video and audio are transmitted peer-to-peer using WebRTC. They go directly to your opponent's device. We do not record, store, or have access to your video or audio streams.
Game data
Game state (moves, clock times) is stored temporarily in server memory while the game is active. It is not persisted after the game ends or the server restarts.
Reports
When you report an opponent, we log the room ID and timestamp. We do not store personal information like names, emails, or IP addresses.
Local storage
We use your browser's localStorage to remember your age confirmation. No cookies, no tracking, no analytics.
