Privacy Policy

Last updated: 2026-06-18. Effective date: 2026-06-18. 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 Services

The app integrates the following third-party SDKs/services to help analyze product stability and optimize user experience:

  • Firebase Analytics (Google Firebase SDK): Collects app usage events, device/app version metadata, and analytics identifiers generated by the SDK to understand usage trends, improve game quality, and diagnose stability issues.
  • Umeng+ SDK (Beijing Ruixun Lingtong Technology Co., Ltd.): Collects device metadata (IP address, device model, OS version, unique device identifiers like IDFA/IDFV/UUID, network type) and app crash logs for crash analysis and usage statistics to improve application stability and performance.

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
