1. Introduction & Commitment
Welcome to Block Master: Classic Puzzel (the "Game"), a high-quality spatial block matching mobile application. We prioritize the protection of your digital privacy. This Privacy Policy outlines what information is collected while playing the game, how it is handled, and the choices you can make regarding your data.
By installing and playing the Game, you agree to the conditions and practices detailed in this document.
Block Master: Classic Puzzel operates under a "Privacy-First" model: we do not maintain private servers that store personal identifying information. Game records, levels unlocked, and sound choices are processed locally in your device's sandbox. Global features are integrated securely through Apple iCloud, Apple Game Center, Google Firebase, and Google AdMob.
- We utilize Google AdMob to display non-disruptive, contextual ads. Ad tracking occurs only with your explicit consent under Apple's App Tracking Transparency framework.
- We utilize Google Firebase for anonymous crash diagnostics and gameplay telemetry (e.g., measuring average combo scores or stage progression speeds).
- We do not request, store, or sell any of your personally identifiable information (PII) on private servers.
- We do not access location coordinates or device contact lists.
2. Information We Collect and How We Use It
While playing the Game, standard systems managed by Apple Inc. and Google LLC are integrated to enable core game functions:
A. Local Game State
Saved securely inside your device sandbox using standard storage parameters (UserDefaults).
- What is stored: Personal high scores, active grid layouts (to resume session), unlocked blocks/themes index, coins collected, level achievements, sound configuration, and vibration presets.
- Purpose: Allows the session state to persist, letting you close and open the app without losing your score or setup.
B. Apple iCloud Synchronization
Backs up session and progress data securely in your private Apple iCloud account via the NSUbiquitousKeyValueStore framework.
- What is stored: A copy of your encrypted Game State settings.
- Purpose: Restores progress if you delete and re-install the app, and synchronizes scores/levels between your iPhone and iPad automatically. The developers cannot access your iCloud details or files.
C. Apple Game Center
Transmits performance milestones to Apple leaderboards if you choose to sign in.
- What is stored: Public Game Center nickname, achievements earned, and top score figures.
- Purpose: Ranks your performance on global leaderboards and tracks milestones. Controlled by your iOS Game Center preferences.
D. App Store Diagnostics & Telemetry
Aggregated diagnostic metrics are sent through Apple's App Store Connect portal if you have shared analytics settings globally.
- What is stored: Anonymous crash reports and execution speeds.
- Purpose: Helps identify software issues and optimization paths across various hardware devices.
E. Google Firebase Telemetry
Processes performance benchmarks anonymously.
- What is stored: Anonymous installation tokens, puzzle combo event logs, screen view counts, and exception logs.
- Purpose: Performance diagnostics and game balance adjustment. No identity metrics are recorded.
F. Google AdMob Advertising
Processes advertisement trackers to support free gameplay.
- What is stored: Mobile advertisement identifiers (IDFA/IDFV), hardware dimensions, and ad click events.
- Purpose: Measures ad campaign success. Advertisements are tailored only if you opt-in to tracking; otherwise, ads are served contextually.
