Block Blitz Choco is a classic block puzzle game developed by Core Nova System. This Privacy Policy explains our data practices in the simplest terms possible: we collect nothing.

This policy applies to the Block Blitz Choco Android application (package name com.choco.blockblitz).

The only data Block Blitz Choco stores locally on your device:

• ✓
  Your best score — Saved in SharedPreferences to track your progress
• ✓
  Sound preference — Whether you have sound effects enabled or disabled

This data is stored in app-private storage and is automatically deleted when you uninstall the app. It never leaves your device.

Block Blitz Choco does not collect, transmit, or store any of the following:

• ✗
  No personal information — No name, email, phone, or contact data
• ✗
  No location data — The app does not access GPS or network location
• ✗
  No device identifiers collected by us — We do not collect IMEI, advertising ID, or device fingerprints. Note: Google AdMob may access the Advertising ID independently for ad serving purposes.
• ✓
  Basic Analytics Only — We use Firebase Analytics and Crashlytics for anonymous app usage statistics (like installs and app opens) and crash reporting to improve the app. We do not track individual users.
• ✗
  No forced advertising — Ads are never shown automatically. Only optional rewarded ads appear when you choose to continue after game over

Block Blitz Choco requests only one Android permission — INTERNET access, required solely for optional rewarded ads. All other permissions remain absent:

• ✓
  INTERNET permission — Required for optional rewarded ads served by Google AdMob
• ✗
  No camera or microphone access
• ✗
  No storage permissions
• ✗
  No contacts or calendar access
• ✗
  No phone, SMS, or call access
• ✗
  No Bluetooth or Wi-Fi access

You can verify this yourself in Settings → Apps → Block Blitz Choco → Permissions.

All sound effects are sourced from Pixabay (pixabay.com) under the Pixabay Content License, which permits free use.

Sound effects are bundled in the app and played locally using Android's SoundPool API. No network activity is involved.

Block Blitz Choco uses only standard Android libraries:

Google AdMob is used to serve various types of advertisements (Banner, Interstitial, App Open, and Rewarded ads). AdMob may collect the Advertising ID and general device info per Google's Privacy Policy. All other libraries listed collect no personal data and make no network requests.

Block Blitz Choco includes advertisements powered by Google AdMob to keep the game free to play. The types of ads you may see include:

• ✓
  Banner Ads: Small ads displayed at the top or bottom of the screen.
• ✓
  Interstitial & App Open Ads: Full-screen ads that may appear when opening the app or between levels.
• ✓
  Rewarded Ads: 100% optional ads you can choose to watch to get an extra life or continue playing.

Google AdMob, as a third-party ad provider, may collect the following as part of ad serving:

This data is collected and processed by Google under their own privacy policy. You can opt out of personalized ads by resetting your Advertising ID in your device settings under Settings → Privacy → Ads.

For full details, see: Google Privacy Policy and How Google uses data from AdMob.

Google Firebase (Analytics & Crashlytics) is used to collect anonymous crash reports and basic usage statistics (such as app installs and session starts) to help us find bugs and improve the game.

Block Blitz Choco is suitable for all ages. Since the app collects no personal information whatsoever and requires no account creation, it is completely safe for children to use.

We do not knowingly collect personal information from anyone, including children under 13.

Your best score and sound preference are stored in Android's SharedPreferences. This data:

• ✓
  Is stored only on your device in private storage
• ✓
  Is automatically deleted when you uninstall
• ✓
  Is never transmitted to any server
• ✓
  Cannot be accessed by other apps

Because no data leaves your device, traditional data breach scenarios do not apply.

Block Blitz Choco is distributed via the Google Play Store. Google Play may collect data about downloads and usage as part of its platform operations, governed by Google's Privacy Policy.

Our Play Store data safety declaration:

• ✓
  No personal data collected or shared by us directly
• ✓
  Google AdMob may collect ad-related data independently as a third-party service
• ✓
  No encryption required for data we transmit (we transmit none)

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last Updated" date at the top.

Since the app collects no personal data, changes are unlikely to affect your privacy. Significant changes will be noted in the Play Store update changelog.

Since Block Blitz Choco does not collect any personal data, most data rights are inherently satisfied. However, you retain the following rights:

• ✓
  Right to deletion — Uninstalling the app permanently deletes all locally stored data (best score, sound preference)
• ✓
  Right to access — You can view your stored data by checking your device's app storage settings
• ✓
  Right to opt-out of personalized ads — You can reset or limit your Advertising ID via Settings → Privacy → Ads on your Android device to opt out of personalized ad targeting by AdMob

This Privacy Policy is intended to comply with applicable privacy laws, including:

As Block Blitz Choco collects no personal data, it operates fully within these regulations by design. Optional rewarded ads are served by Google AdMob in compliance with applicable advertising laws.
