Shift ("we," "our," or "us") is a daily word puzzle game for iOS. This policy explains what information we collect, how we use it, and your choices.

Information We Collect

Information you provide:

If you create an account, we collect your first name and email address, or your name from Apple or Google if you sign in that way.

Information collected automatically:

Game data — your puzzle results, guess history, streaks, and win/loss record. Stored on your device and, if signed in, synced to our cloud database (Firebase Firestore).
Analytics — anonymized usage data such as puzzles started, guesses submitted, and win/loss events. Provided by Firebase Analytics. On iOS 14+, only collected if you grant App Tracking Transparency permission.
Device information — basic info such as device type and iOS version, collected by Firebase.

How We Use Your Information
