Privacy Policy

TopSpin Round Robin — Last updated July 2026

TopSpin Round Robin ("the app") is a tournament management app for sports clubs and players. This policy explains what information we collect, how it's used, and the choices you have.

Information We Collect

We never see or store your password. Signing in with Apple, Google, or your phone number is handled entirely by Apple, Google, or our authentication provider (Firebase) — they verify your identity and hand our app a secure, revocable session token, not your password. We have no access to your Apple ID, Google account, or phone carrier credentials at any point.

How We Use Information

We use this information solely to operate the app: to run tournaments and round robins, show nearby clubs and players, track match results and stats, and send you notifications you've opted into. We do not sell your information, and we do not use it for advertising.

Where Information Is Stored

App data is stored using Google Firebase (Authentication, Firestore database, and Cloud Messaging), which acts as our data processor. Firebase's own privacy practices are described at firebase.google.com/support/privacy.

Sharing With Other Users

Your display name, match results, and club membership are visible to other players and hosts within clubs you connect to, since the app is inherently social/competitive (tournaments, standings, challenges). Your phone number and email are never shown to other users.

Your Choices

Children's Privacy

TopSpin Round Robin is not directed at children under 13, and we do not knowingly collect information from them.

Changes to This Policy

We may update this policy as the app evolves. Continued use of the app after a change means you accept the updated policy.
