Rarissimo does not collect, store or share any personal data.

No account, no sign-in.
No analytics, no advertising, no tracking.
Your settings (language, sound), team names and saved game are stored only on your device and are deleted when you delete the app.

What the app sends and receives

Anonymous answer statistics. After each round, the app sends to Google Firebase Cloud Firestore which answers were given in that category and how many teams played it. When the table accepts a correct answer that is not in the list, the text of that answer (up to 60 characters) is included, so please do not type personal information there. No name, identifier or device information is attached. These statistics are used to show how rare each answer is.
App protection. The app uses Firebase App Check, which relies on Apple DeviceCheck or Google Play Integrity to confirm that requests come from the genuine app. This does not identify you.
Category updates. The app downloads the list of categories from Firebase Hosting, so new categories can arrive without an app update.

These services are provided by Google. See the Firebase privacy information.
