Last updated: October 6, 2026. Contact: rasetmengine@hotmail.com

What we collect

We do not collect precise location, contacts, photos, microphone or camera data, advertising IDs or payment information. The app contains no ads and no third-party analytics.

How we use it

To sign you in, match you with opponents, validate moves and clocks, calculate ratings, show leaderboards and tournament standings, and keep the service secure and fair.

Who processes it

Data is stored and processed by our backend provider Supabase (database, authentication, server functions). Google Sign-In is used if you choose it. We do not sell your data and do not share it for advertising. Your display name, rating and game results are visible to other players (leaderboard, opponent name, tournament standings). Your e-mail address is not shown to other players.

Security

Data is transmitted over encrypted connections (HTTPS/TLS). Database access rules restrict what each user can read or change.

Retention and deletion

We keep your data while your account exists. You can delete your account and personal data at any time inside the app (Lobby → “Delete my account”) or via the page Account deletion. After deletion your profile, ratings and tournament data are removed; past games may remain without any link to your name.

Children

The app is not directed to children under 13 and we do not knowingly collect their data. If you believe a child has provided data, contact us and we will delete it.

Changes

We may update this policy; the date above shows the latest version.
