Word Lounge Privacy Policy

Last updated: October 11, 2026 · Effective: October 10, 2026

This privacy policy explains how the mobile application Word Lounge: Multilingual Vocabulary & Grammar Learning (hereinafter "Word Lounge" or "the app") processes user data. Word Lounge does not create an account or ask you for personal information (name, email, phone); your learning data stays on your device. The app only uses some third-party services for optional purchases, the online match feature, and loading fonts.

1. Data Controller

App Owner: MFK Apps Studio
Contact: appsmfk@gmail.com

2. Data Collected

2.1 Tracking and Analytics Data

Word Lounge does not use Firebase, Crashlytics, crash reporting, its own analytics, or any other tracking SDK.

2.2 Data Stored Locally (Never Leaves the Device)

  • Your learning progress: studied/mastered words, memory levels, the mistakes pool.
  • Scores, XP, streak, daily goal and statistics.
  • Energy, coins, unlocked themes and power-ups.
  • Your settings (known/learning language, level, sound, etc.) and the nickname you enter in the app.

All of this is kept only in your device's local storage (localStorage) and is not sent to a server of ours. Uninstalling the app deletes this data.

2.3 Online Match Data

In online match mode, only the nickname and room code you enter are shared directly with your opponent over a peer-to-peer (P2P) WebRTC connection, for matchmaking. A free signaling service (PeerJS) and connection-helper servers (STUN/TURN) are used to establish the connection. This mode stores no account, chat, or game history on a server; if you don't use the feature, no data is shared.

3. Purpose of Use

  • Providing app functionality (storing progress, scores, and settings on device)
  • Managing optional Premium subscriptions and purchases
  • Matching two players in online match

4. Third-Party Services

  • Google Play Billing (Premium subscriptions and purchases on Android) — Privacy policy
  • Apple App Store / StoreKit (Premium subscriptions and purchases on iOS) — Privacy policy
  • PeerJS signaling + STUN/TURN servers (only for the online match connection)
  • Google Fonts (loading interface fonts) — Privacy policy

No other third-party services (social SDKs, attribution services, etc.) are used.

5. Permissions

  • Notifications (Android 13+ and iOS): Only to show study reminders. You may decline; the app still works.
  • Internet: For online match, purchases, and loading fonts.

No location, camera, microphone, contacts, or storage permission is requested.

6. Data Security

  • All internet traffic is encrypted with HTTPS/TLS
  • Your learning data never leaves your device
  • Premium payments are handled by Google Play or the App Store; no card data reaches Word Lounge

7. User Rights (KVKK / GDPR)

Under KVKK Article 11 and GDPR Articles 15-22, you have the right to access, correct, delete, and object to the processing of your data. Since all your learning data is stored on your device, you can permanently delete it in a single step from within the app (Settings → Reset progress) or by uninstalling the app. For other requests, contact appsmfk@gmail.com.

8. Children's Privacy

Word Lounge is suitable for all ages and does not knowingly collect personal data from users under 13.
