1. Information We Collect

When you sign up and use Quadra, we collect the following information:

When you sign in with Google or Apple, we receive your name and email address from the respective provider. We do not receive your password or any other account credentials. Please refer to Google's Privacy Policy and Apple's Privacy Policy for details on how they handle your data.

1. Account creation and authentication: To create and manage your Quadra account via Google or Apple sign-in.
2. Player matchmaking: To show you nearby players and match requests based on your location, skill level, and availability.
3. Rankings and statistics: To calculate and display Elo-based rankings at the city, state, and country levels.
4. Social features: To power the social feed, clubs, kudos, comments, and community features.
5. Notifications: To send you push notifications about match requests, score confirmations, ranking changes, club activity, and match reminders.
6. Map features: To display nearby players on a map at approximate (neighborhood-level) locations.
