Cookie Notice

Last updated: 9 August 2026

Required private-game cookie

When you create or explicitly join a private game in a web browser, Real-Time Chess sets one strictly necessary, HttpOnly seat cookie for that room. It lets the same browser recover its seat after a refresh while the room remains active. It is scoped to that room, uses SameSite=Lax, and expires within 24 hours.

What we do not use

v1 does not use advertising, analytics, preference, or tracking cookies. It does not use browser storage to simulate multiplayer.

Native apps keep the equivalent room credential in the operating system's secure storage rather than a browser cookie. See the Privacy Policy for more detail or contact contact.real.time.chess@gmail.com.
