Privacy Policy

Last updated: April 21, 2026

We built Sparr to be a simple, free card game. We collect only what we need to make the game work and keep your account secure. We do not sell your data.

1. Information We Collect

Account information. When you sign in with Google, Facebook, or email, we receive your display name and email address to create your player profile.

Gameplay data. We store your game history, wins, losses, and statistics in Firebase Firestore to power the leaderboard and your profile.

Device information. Firebase and Google AdMob may collect device identifiers (such as advertising ID), operating system version, and IP address for analytics and ad targeting.

Push notification token. If you grant permission, we store a Firebase Cloud Messaging token to send you in-app notifications about your games.

2. How We Use Your Information

To authenticate your account and keep it secure
To display your stats, rank, and game history
To match you with other players and manage game lobbies
To send game notifications (only when you've granted permission)
