Privacy Policy for Fun Words
At Fun Words (published by MarvinDev), we are committed to transparent, privacy-first gaming. This policy explains what information we collect, how your multiplayer game progress is synchronized, and how you can exercise full control over your personal data.
This Privacy Policy applies to the mobile game application Fun Words ("the App", "Service"), developed and published by MarvinDev ("we", "us", or "our").
Under international data protection regulations, including the European Union General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA/CPRA), MarvinDev acts as the Data Controller for personal data collected in connection with the App.
If you have questions regarding this policy, our Data Protection Officer and support team can be reached at: funwords@marvindev.store.
Fun Words is strictly designed for a general audience aged 13 and older (or 16 and older in jurisdictions within the European Economic Area).
We comply with the Children's Online Privacy Protection Act (COPPA) and the Google Play Families Policy:
- We do not knowingly market to, target, or collect personal information from children under the age of 13.
- If we become aware that a child under the age of 13 has provided personal data (such as via Google Sign-In), we immediately purge that account and all associated cloud data from our databases.
- If you are a parent or legal guardian and believe your child under 13 has submitted personal information to Fun Words, please contact us immediately at funwords@marvindev.store for swift deletion.
To enable competitive multiplayer matchmaking, word validation, leaderboards, and turn synchronization, we collect the following categories of data:
A. Account Credentials & Profile Data
When you sign in using Google Sign-In or link an authentication provider via Firebase Auth:
- Google Account Identifiers: Unique Firebase User ID (UID), verified email address, public display name, and avatar photo URL (if provided by Google).
- Guest/Anonymous Mode: If you play as a guest, a temporary anonymous UID is generated to maintain your game state locally and securely sync match sessions without storing personal identity.
B. Gameplay & Multiplayer Activity
- Match Logs: Board tile placements, submitted words, validated scores, bonus multipliers (e.g. Triple Word, Double Letter), turn timestamps, and match outcome records.
- Player Statistics: Overall rating (ELO/MMR), total wins, losses, forfeits, highest-scoring words, and global/friends leaderboard rankings stored in Cloud Firestore.
C. Technical & Diagnostic Metrics
- Crash & Performance Diagnostics: Crash stack traces, non-fatal exceptions, and device performance metrics collected via Firebase Crashlytics and Firebase Performance Monitoring to fix bugs.
- Device Specifications: Device model, OS version (Android/iOS), CPU architecture, app version code, and network connection status.
- Push Notification Tokens: Firebase Cloud Messaging (FCM) registration tokens used solely to notify you when it is your turn or when an opponent moves.
Zero Third-Party Ads & Zero Data Brokering
Fun Words contains no third-party banner or video ads. We do not track you across other applications or websites, and we never sell, rent, or trade your personal information to data brokers or advertising networks.
- No Payment Card Data: We never collect or store your credit/debit card numbers, bank account details, or billing addresses.
- No Precise Geolocation: We do not access or request GPS fine-location permissions.
- No Sensitive Hardware Access: We never access your camera, microphone, contacts, biometric data, or photo library.
We use personal and gameplay data strictly for legitimate operational purposes:
- Gameplay Synchronization: Real-time transmission of tile moves, board states, and active lobbies between opponents via Firebase Realtime Database.
- Anti-Cheat & Match Integrity: Validating word legality, tile counts (100-tile letter bag), and turn timers on our backend rules engine.
- Account Management: Syncing your player profile, unlocked cosmetic themes, and virtual coin balance across multiple devices.
- Notifications: Alerting you when your opponent has played a move or invited you to a match.
- App Stability: Monitoring crash logs to identify and patch bugs before releasing app updates via Google Play In-App Updates.
We rely on vetted infrastructure providers that adhere to industry-standard data security and privacy practices:
Google Play Billing
Processes in-app purchases, cosmetic themes, and virtual coin packages securely.
Firebase Authentication
Secure token-based sign-in with Google and anonymous guest accounts.
Cloud Firestore

In accordance with Google Play policies and our terms, virtual currencies and cosmetic unlocks linked to an account are permanently forfeited upon completed account deletion requests.
