Privacy Policy

Last updated: 2026-04-30. Effective date: 2026-04-30. This policy explains how GuessWord Lab handles data in the current game version.

1. Scope

This policy applies to your use of GuessWord Lab gameplay, history, and lexicon settings. It does not apply to third-party websites outside our app and website.

2. Data Processed Locally

  • Gameplay records: guessed words, similarity scores, guess count, timestamps, and session status
  • Session metadata: target word for each round and embedding model name used by the game engine
  • Preference data: lexicon setting (follow system / Chinese / English)

In the app, these records are stored in local sandbox storage (for example, Application Support and UserDefaults).

3. Data Sent to Third-Party Service

The app integrates Firebase Analytics (Google Firebase SDK). When you use the app, analytics events and related technical metadata may be transmitted to Firebase for product analysis and service improvement.

  • Examples: app usage events, device/app version metadata, and analytics identifiers generated by the SDK
  • Purpose: understand usage trends, improve game quality, and troubleshoot stability issues

4. How We Use Data

  • Run core gameplay and history features
  • Persist your lexicon preference and game progress locally
  • Analyze aggregated usage behavior to improve gameplay experience

5. Sharing and Disclosure

  • We do not sell your personal information
  • Local gameplay data is not shared with third parties for advertising sale
  • Analytics data is processed by Firebase according to applicable legal and platform requirements
  • We may disclose required information when mandated by law or competent authorities

6. Retention and Security

  • Local game data remains on your device until app deletion or local data cleanup by system means
  • Analytics retention follows Firebase service-side retention mechanisms
  • We apply reasonable measures, but no technical method is absolutely secure

7. Your Rights

  • Access: view your game history and statistics inside the app
  • Deletion: uninstall the app to remove locally stored game data on device
  • Contact: request privacy support via email below

8. Children's Privacy

If you are a minor, use GuessWord Lab under parent or guardian guidance.

9. Policy Updates & Contact

We may update this policy as features or legal requirements change. Updated versions will include a new last-updated date.
