Privacy Policy — Starfield Memory

Last updated: May 22, 2026

Starfield Memory ("the app", "we") is a single-player memory and perception game with an optional online leaderboard and an optional local Wi-Fi multiplayer mode. This policy explains what information the app handles, where it goes, and how you can control it.

1. Summary

• You can play as a Guest without signing in. All your progress stays on your device only.
• If you sign in with Apple or Google, your game progress is stored in our cloud backend (Firebase) so it syncs between your devices and your name can appear on the leaderboard.
• The app shows ads (Google AdMob) and you can opt out of personalised ads at the system level on iOS and Android.
• We do not sell your data.

2. What information is collected, and why

2.1 Always (whether or not you sign in)

• Game state stored on your device — scores, ranks, streaks, daily challenge results, achievements, settings, and the display name you optionally enter. This is kept in the app's local storage on your device and is not transmitted by us as long as you remain a Guest.
• Anonymous identifier (Firebase Anonymous Auth) — so the app can submit your score to the public leaderboards even before you sign in, an anonymous identifier is created. It is a random string with no link to your real identity.
• Leaderboard entries (Firebase Firestore) — when you complete a run, the app submits your display name, score, level reached, and a server-generated timestamp to one or more of these public collections: dailyResults, weeklyXp, allTime. These rows are readable by every player.
• Advertising identifiers (Google AdMob) — to show banner ads, AdMob may collect device identifiers (such as IDFA on iOS) and basic technical information about your device. This is governed by Google's privacy policy.

2.2 Only if you sign in with Apple or Google

• Your provider-issued user identifier from Apple or Google, used by Firebase Authentication to associate your sign-in with a stable Firebase account.
• Email address and display name — when you sign in with Apple or Google, we receive an email address (or Apple's private relay address if you chose Hide My Email) and a display name. The display name is stored locally and used on the leaderboard. The email is stored only in Firebase Authentication so we can recognise you on your next sign-in.
• Cloud-synced game state (Firebase Firestore) — while signed in, the same per-device game state listed in 2.1 is additionally mirrored to your private user document (/users/{your-uid}) so it can sync to your other devices.

2.3 During local Wi-Fi multiplayer (Versus mode)

Versus connects two devices on the same local Wi-Fi network via a peer-to-peer WebSocket. The only information exchanged between players is the display name you choose and gameplay events (taps, scores). Nothing is sent to any external server, and nothing is retained after the match ends.

3. Who has access to what

4. Third-party services we rely on

• Firebase (Google LLC) — Authentication, Firestore database. See firebase.google.com/support/privacy.
• Google AdMob (Google LLC) — banner ads. See policies.google.com/privacy.
• Sign in with Apple (Apple Inc.) — optional sign-in provider. See apple.com/legal/privacy.
• Sign in with Google (Google LLC) — optional sign-in provider. See the Google privacy policy above.

5. Tracking and analytics

We do not run our own analytics or advertising. We do not track your use of the app across other apps or websites. Advertising identifiers used by AdMob are governed by Google.

On iOS, ad tracking is controlled by Apple's App Tracking Transparency prompt. You can change this any time in Settings → Privacy & Security → Tracking. On Android, you can reset or limit your advertising ID in Settings → Privacy → Ads.

6. Children

The app is rated suitable for all ages. We do not knowingly collect personal information from children under 13 (under 16 in the EEA). If you believe a child has provided us with personal information through sign-in, please contact us at contact@fluttech.com and we will delete the account and associated data.

7. Your choices

• Reset all local game data: uninstall the app, or use iOS Settings → Starfield Memory → Reset where available.
• Sign out: in the app go to Settings → Account → Sign out. Your cloud-stored game state stays in our backend in case you sign back in.
• Delete your account and cloud-stored data: email us at contact@fluttech.com from the email address tied to your sign-in, or send the Firebase UID shown in the app's Settings screen, and we will remove your Firebase Authentication record, your private user document, and your leaderboard rows within 30 days.
• Limit ad personalisation: iOS Settings → Privacy & Security → Apple Advertising; Android Settings → Privacy → Ads.

8. Data retention

Local game state is kept on your device until you delete the app or reset its data. Cloud-stored data (Firebase Auth record, private user document, leaderboard rows) is retained while your account is active and removed within 30 days of a deletion request.

9. International transfers

Our Firebase project is hosted in the European Union (Frankfurt region). Some Google sub-processors may process data in other regions; see the Google privacy policy linked above for details.

10. Changes to this policy

If we update this policy, the "Last updated" date above will change. Continued use of the app after a change means you accept the updated policy.
