Privacy Policy

This Privacy Policy describes how Block Puzzle Master (the "App") handles information when you play on your mobile device. We believe in transparency: we do not directly collect or retain your personal identity, though third-party ad services (Google AdMob) may collect standard device metrics to display advertising.

The App is developed and operated by an independent developer. By installing or using the App, you agree to this policy.

Section 1

Local Data Storage

The developer does not operate external servers that collect or store your personal data. The App stores the following gameplay preferences locally on your device only, using Android/iOS standard local storage:

• Your best scores for each game mode (Classic, Fill, Block Sliding, Jewel, Move Block)
• Sound on/off preference
• Background music on/off preference
• Haptic feedback on/off preference

All of this local data is deleted automatically when you uninstall the App.

Section 2

Advertising & Third-Party Services

To support the continued development of this game, the App integrates Google AdMob to display Banner and Rewarded video advertisements.

While the App does not harvest personal details, Google AdMob and its advertising partners may automatically process certain technical data to serve ads, prevent fraud, and measure campaign performance. This data may include:

• IP address (used to infer coarse/general location)
• Advertising ID (AAID on Android, IDFA on iOS)
• Device model, screen size, and OS version
• Ad interaction, impression data, and diagnostic/crash logs

For more information on how Google collects and processes data, please review:
How Google uses information from sites or apps that use their services

Section 3

Open-Source Libraries

The App is built with the open-source Flutter framework. The following core open-source libraries are bundled inside the App:

• Flutter (Google, BSD-3 license) — UI framework
• google_mobile_ads — Google Mobile Ads SDK integration
• flutter_bloc — state management
• flame & flame_audio — game rendering and audio playback
• shared_preferences — local key-value storage
• google_fonts — typeface rendering (fonts are bundled locally)

Section 4

Children's Privacy

We value children’s privacy rights. The App is designed to comply with the Children's Online Privacy Protection Act (COPPA) and applicable Google Play policies. We do not knowingly collect personal information from children under 13. AdMob integration is configured to treat ad requests in compliance with applicable child safety guidelines.

Section 5

Data Security

Your local preferences and high scores are protected by your mobile device's own security framework (PIN, biometrics, disk encryption). Any network traffic initiated by third-party SDKs (such as AdMob) is protected using standard, encrypted TLS connections.

Section 6

Changes to This Policy

If we make material changes to this Privacy Policy, we will update the "Last updated" date at the top of this page. Continued use of the App after any changes constitutes acceptance of the updated policy.
