Privacy Policy — DailyBrain

Last updated: September 24, 2026

1. Introduction

DailyBrain ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains what information the app stores on your device, what limited technical information it collects automatically, and the controls available to you. DailyBrain requires no account, sign-up, or login.

2. Information We Collect

DailyBrain has no accounts, no sign-in, and no server of our own. All game progress, settings, and statistics are stored locally on your device using SQLite and never leave your device. We do not sell your data and we do not share personal information with third parties.

The app does use third-party advertising, analytics, and crash-reporting services, which transmit app-usage and diagnostic information as described in Sections 3 and 5. DailyBrain also periodically requests a small public version file over HTTPS in order to check for updates; that request contains no personal information.

3. Advertising and Consent

We use Google AdMob to show ads that support the app and keep it free:

• Banner ads on the Home and Results screens
• Rewarded ad — only when you choose to watch one to unlock an extra hint or double a puzzle's XP
• Rewarded interstitial ad — only when you choose to support the app (heart button)

No ads are shown during gameplay, during tutorials, while a puzzle is paused, or on the splash screen.

Before any personalized advertising, the app asks for your consent using Google's User Messaging Platform. You can review or change that choice at any time in Settings → Privacy Options. AdMob and its partners may collect device identifiers (advertising ID), IP address, and usage data in order to select and measure ads. You can also opt out of ad personalization in your device settings:

• Android: Settings → Google → Ads → Opt out of Ads Personalization

AdMob's privacy policy is available at: https://policies.google.com/privacy

4. Data Storage and Deletion

• All game data (puzzle progress, XP, streaks, settings) is stored locally on your device using SQLite.
• No cloud sync and no backup to our servers — we do not operate servers.
• You can delete all data at any time via Settings → Reset Progress, or by uninstalling the app.
• Android device backup: if backup is enabled in your Google account settings, Android may copy app data to your own encrypted Google backup so it can be restored on a new phone. That backup is controlled by you and Google — we cannot access it. You can turn it off in Android Settings → System → Backup.

5. Third-Party Services

• Google AdMob — advertising
• Google Firebase Analytics — aggregated, non-identifying usage analytics
• Google Firebase Crashlytics — crash reports and diagnostic data
• Expo / React Native — application framework

These services process data under their own privacy policies. We never send them the contents of your game progress or your display name.

6. Device Permissions

• INTERNET — ads, analytics, and update checks
• VIBRATE — haptic feedback
• POST_NOTIFICATIONS — optional local reminders (Android 13+)
• AD_ID (provided by Google Play services) — advertising identifier used by AdMob

Notifications are scheduled locally on your device. No notification data is sent to any server.

7. Your Choices and Controls

• Change your ad consent choice — Settings → Privacy Options
• Limit ad personalization — your device settings
• Turn notifications off — the in-app prompt, or your device notification settings
• Remove all local data — Settings → Reset Progress, or uninstall the app
• Request deletion of analytics or crash data associated with your app usage — email us and we will action the request

8. Children's Privacy

DailyBrain does not knowingly collect personal information from children under 13. The app is rated "Everyone" and contains no mature content. If you believe a child has provided such information, contact us and we will delete it.

9. Changes to This Policy

If this policy changes, the "Last updated" date at the top will be revised. Material changes will also be reflected in the app.

10. Contact

DailyBrain is developed by Ankit Dholakiya (HDApps), India.
