Effective date: July 29, 2026
This Privacy Policy explains how Mango Games ("we", "us") handles information in the Sudoku Master mobile app ("the App"). We built the App to work with as little personal data as possible — there is no email/password account, and we never ask for your name, phone number, or physical address.
Information we collect
| Data | Why |
|---|---|
| Anonymous device identifier (Firebase Anonymous Auth UID) | Lets your progress, stats, and online matches sync without creating an account |
| Username you choose | Displayed to other players in matches, friends lists, and leaderboards |
| Gameplay data (level, XP, win/loss count, daily challenge times) | Powers XP progression, matchmaking, and leaderboards |
| Advertising identifier (IDFA), only if you allow tracking | Used by our ad partner (Google AdMob) to show and personalize ads |
We do not collect your real name, email address, phone number, precise location, or any government identifiers. There is no way for other players to learn your real-world identity from the App.
How we use your information
- To operate core features: single-player games, real-time 1v1 matches, friends, leaderboards, and the daily challenge.
- To calculate and store your level, XP, and win record.
- To show ads (banner, interstitial, and rewarded) through Google AdMob, which may use the advertising identifier for personalization if you grant tracking permission via Apple's App Tracking Transparency prompt. If you decline, you'll still see ads, just not personalized ones.
Third-party services
The App uses the following third-party services, each governed by its own privacy policy:
- Firebase (Google) — authentication, database, and backend logic.
- Google AdMob — advertising.
Data retention & deletion
Your gameplay data is retained as long as you use the App. You can request deletion of your data at any time by contacting us at the email below with your in-app username — we'll remove your profile, stats, and match history from our systems.
Children's privacy
Sudoku Master is a general-audience puzzle game and is not directed at children under 13. We do not knowingly collect personal information from children. Because the App does not collect names, emails, or other directly identifying information, exposure is inherently limited.
Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the effective date above.
