Mini Mart – Privacy Policy
Summary
Mini Mart is a casual shop-building game. We collect only what the game needs to run its online leaderboard and optional Google Play Games sign-in. The game has no ads, no in-app purchases, no analytics or tracking, and we never sell your data.
Information we collect
| Data | Why | Where it is kept |
|---|---|---|
| Game progress (money, shops, upgrades, settings) | To save your game | Only on your device |
| Leaderboard name (a random “Guest1234” name, a name you type, or your Google Play Games name) | Shown on the public leaderboard | Google Firebase (Cloud Firestore) |
| Leaderboard score (total money earned in the game) and the time it was last updated | To rank players | Google Firebase (Cloud Firestore) |
| An anonymous account ID created by Firebase Authentication | So only you can update your own leaderboard entry | Google Firebase (Authentication) |
| Google Play Games player ID and display name – only if you choose “Sign in with Google Play” | To sign you in and keep your leaderboard entry across devices | Google Play Games Services and Google Firebase (Authentication) |
We do not collect your email address, phone number, contacts, photos, location, or payment details. Like any internet service, Google’s servers may process technical data such as your IP address when the game connects to them.
What other players can see
The leaderboard is public inside the game: other players can see your leaderboard name and score. Please don’t use your real full name or other personal information as your leaderboard name. You can change it at any time with the ✏️ button on the leaderboard.
Third-party services
The game uses these Google services, which process data under their own policies:
- Google Firebase (Authentication, Cloud Firestore) – Firebase privacy and security
- Google Play Games Services – Google Privacy Policy
We do not share your information with anyone else.
Keeping and deleting your data
- On your device: Settings → Progress → Reset deletes your saved game. Uninstalling the app removes all game data from your device.
- Google Play: Settings → Sign out stops the game from using your Google Play account. You can manage your Play Games data in the Google Play Games app.
- Leaderboard and account: your leaderboard entry and Firebase account are kept while the game is available. To have them deleted, email hello@helloworldtech.com with your leaderboard name; we will delete them within 30 days.
Security
Data is sent over encrypted connections (HTTPS) and stored on Google’s servers. Security rules allow each player to change only their own leaderboard entry.
Children
Mini Mart is suitable for a general audience. We do not knowingly collect personal information from children under 13. The only information a player can enter is a leaderboard name; if you believe a child has entered personal information, contact us and we will delete it.
Changes to this policy
If we change this policy, we will update this page and the effective date above.
