BrainBox: Offline Puzzle Games ("BrainBox," "we," "our," or "the App") is an offline casual puzzle and arcade gaming collection. Your privacy is paramount: BrainBox is designed from the ground up to operate offline on your device, with no account registration, no remote user profiling, and no server-side tracking of your scores or gameplay.

1. Overview & Core Philosophy

BrainBox brings together 10 classic games: Queen, ZIP, Sudoku Master, 2048 Neon, Block Puzzle, Tic-Tac-Toe, Snakes & Ladders, Memory Match, Retro Snake, and Fruit Slicer. The App functions completely offline without requiring an internet connection. We believe you should be able to enjoy relaxing, brain-challenging games without surrendering personal data or creating unnecessary accounts.

2. Information Stored Locally On Your Device

The App records only the minimal gameplay data required for local progress, high scores, reward coins, VIP purchase entitlement status, and game settings. This information is saved solely in private app storage on your device:

3. How Your Data Is Stored (Offline DataStore)

All game records, scores, and preferences are stored exclusively on your device using Android Jetpack DataStore. We do not run external servers, user databases, or cloud accounts for this application. If you clear the App's data in Android Settings or uninstall BrainBox, all local scores and coins are permanently removed from your device (while any completed one-time VIP purchase remains linked to your Google Play account and can be restored anytime via Google Play Billing).

4. What We Do Not Collect

BrainBox does not collect, record, or transmit:

• Personal identifiers such as your real name, email address, or phone number.
• Credit card numbers, bank account details, UPI IDs, or billing addresses (all payment processing is handled exclusively by Google Play).
• GPS or precise geographical location data.
• Contacts, address books, photos, media files, or documents stored on your device.
• Microphone or camera recordings.
• Biometric data of any kind.

5. In-App Purchases & Google Play Billing (One-Time Purchase)

BrainBox offers an optional one-time, non-consumable in-app purchase - the Lifetime VIP Pass: Remove Ads & Unlimited Coins.

• Payment Processing by Google Play: All financial transactions and billing operations are processed directly and securely by Google Play Billing through your Google Play Store account. BrainBox never collects, views, processes, or stores your credit card details, bank information, or payment credentials.
• Purchase Verification & Restore: On app launch or when you tap "Restore Existing Purchase", the App queries the official Google Play Billing API on your device to verify whether your Google Play account owns the entitlement. Only a local boolean status (true/false) is saved in on-device DataStore so your ad-free and unlimited-coin benefits work seamlessly offline.
• Zero Ads After Purchase: Once the one-time purchase is active or restored, all Google AdMob banner, interstitial, and rewarded video ad requests are permanently disabled within the App.

For information on how Google handles payment and transaction data, please review the Google Privacy Policy and Google Payments Privacy Notice.

6. Third-Party Advertising (Google AdMob)

To keep BrainBox free to play for users who have not purchased the Lifetime VIP Pass, we use Google Mobile Ads (AdMob) to display non-intrusive banner, interstitial, and rewarded advertisements when an internet connection is present. If you purchase the one-time Remove Ads pass, all AdMob advertisements are completely disabled.

Google AdMob may collect and process pseudonymous device identifiers (such as the Android Advertising ID), general IP-based approximate location (country/city level), and diagnostic data to serve ads, combat fraud, and measure ad performance in compliance with Google Play Developer Policies.

You can control or reset your Android Advertising ID at any time through your device settings:
Settings > Google > Ads > Reset Advertising ID / Delete Advertising ID.

For more details on how Google processes ad data, please review Google's Advertising Privacy & Terms.

7. Device Permissions

BrainBox uses the following Android permissions strictly for the functions described:

• INTERNET & ACCESS_NETWORK_STATE: Used by Google Play Billing to process or restore your one-time VIP purchase, by Google AdMob to load advertisements (when VIP is not purchased), and by the in-app update manager to notify you when a newer version is available on Google Play. Gameplay remains 100% playable offline.
• com.android.vending.BILLING: Used exclusively by the Google Play Billing library to display localized pricing, process the one-time Remove Ads & Unlimited Coins purchase, and restore existing purchases across your devices.
• VIBRATE: Used to provide tactile haptic feedback during game moves (e.g. slicing fruit, placing marks on the Tic Tac Toe grid, and climbing ladders). You can turn vibration off at any time in the in-game Settings menu.
• POST_NOTIFICATIONS: (Optional, Android 13+) Used only if you choose to receive friendly notifications.

8. Resetting & Deleting Your Game Data

You have full control over all stored game data directly from within the App:

• Reset High Scores: Accessible via the Settings bottom sheet on any game screen. Resets all high score records to zero while preserving your reward coin balance and any active VIP purchase.
• Reset All Progress: Reverts all high scores, coin balances, and settings back to initial factory defaults while preserving your Lifetime VIP Pass if purchased.
• System Clear Data / Uninstall: You can also clear app storage via Android system settings or uninstall BrainBox to permanently wipe all local files. If you reinstall the App later using the same Google account, your one-time VIP purchase is automatically restored from Google Play.

9. Children's & Family Privacy

BrainBox is designed to be family-friendly and suitable for players of all ages. We comply with the Children's Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR-K), and Google Play Families Policies:

• We do not knowingly collect personal information from children under the age of 13.
• All ads displayed via Google AdMob are configured to comply with Google Play Families and kid-appropriate content guidelines.

10. Changes to This Privacy Policy

We may occasionally update this Privacy Policy to reflect app updates, new game features, or changes in legal regulations. When changes occur, the "Last updated" date at the top of this page will be revised. We recommend reviewing this policy periodically.
