Last updated: October 16, 2026 · Effective: October 16, 2026

Thank you for choosing MathSurge ("we", "our", or "us"). This Privacy Policy explains how your information is handled when you use the MathSurge mobile application.

1. Summary: Offline-First & Privacy-Focused

MathSurge is designed as an offline-first mental math training application.

• We do not require user accounts or registration.
• We do not collect or store personal identifiers like your name, email address, phone number, or location on our servers.
• All game progress, personal best scores, XP levels, streaks, and mistake vault records are stored locally on your device.

2. Information Handled by Third-Party Services (Advertising)

MathSurge uses Google AdMob (Google Mobile Ads SDK) to display banner and interstitial advertisements in the application.

Google AdMob may collect and process certain data in accordance with Google's Privacy Policy, including:

• Device identifiers: IP address, mobile advertising identifier (such as the Android Advertising ID), and device hardware specifications.
• Usage data: Diagnostic information, ad impression metrics, click interactions, and crash reports.

Consent (EEA, UK and Switzerland)

If you are in a region where consent is required, MathSurge shows Google's consent form before any ads are requested. You can review or change your choice at any time in Settings › Data Management › Privacy Options.

Your choices (United States)

If you live in a US state with consumer privacy laws (such as California), MathSurge shows Google's privacy message, which lets you opt out of the sale or sharing of your personal information for advertising. You can change this choice at any time in Settings › Data Management › Privacy Options.

Opting out of personalized ads

You can opt out of personalized advertisements through your Android device settings:

• Open Settings › Google › Ads (on some devices, Settings › Privacy › Ads).
• Tap Delete advertising ID or enable Opt out of Ads Personalization.

3. Data Storage & Deletion

• Local device storage: All gameplay history, question splits, and custom configurations remain within the app's local storage on your device.
• Data deletion: You can delete all locally stored game data at any time via Settings › Data Management › Reset All Progress in the app, or by clearing the app's storage in Android Settings.

4. Children's Privacy

MathSurge is intended for users aged 13 and older and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has used the app and that data about them has been collected by our advertising partner, please contact us and we will help you request its deletion.

5. Permissions Requested

MathSurge requests only the permissions required for advertising:

• android.permission.INTERNET: Used by the Google Mobile Ads SDK to request and display banner and interstitial ads.
• android.permission.ACCESS_NETWORK_STATE: Used to check whether the device has an active internet connection before requesting ads.
• com.google.android.gms.permission.AD_ID (added by the Google Mobile Ads SDK): Lets the SDK read your device's advertising ID for ad delivery and measurement.

Spoken questions in the Blindfold Audio arena use your device's built-in text-to-speech engine; the text spoken never leaves your device through MathSurge.

MathSurge does not request access to your camera, microphone, contacts, location, or file storage.
