Privacy Policy
Last updated: April 7, 2026
Gomoku Z ("the app") is developed by Iwan BK. This policy explains what data is collected when you use the app and how it is used.
1. Data We Collect
The app collects only the minimum data necessary to function:
- Anonymous User ID — Firebase Authentication signs you in anonymously. No name, email, or phone number is required or stored. The anonymous ID is used solely to identify your game session.
- Game Data — Moves, game results, and room state are stored in Cloud Firestore to enable online multiplayer. This data is not linked to any personal identity.
- Local Statistics — Win/loss/draw counts and preferences (theme, language, sound) are stored locally on your device using SharedPreferences. They are not uploaded to any server.
- Advertising Data — The app uses Google AdMob to display ads. AdMob may collect device identifiers and usage data to serve relevant ads. See Google's Privacy Policy for details.
2. Data We Do NOT Collect
- Name, email address, phone number, or any personally identifiable information
- Location data
- Contacts or files on your device
3. Third-Party Services

4. Data Retention
Game room data in Firestore is automatically cleaned up after a match ends. Anonymous accounts that have been inactive for an extended period may be deleted.
5. Children's Privacy
