Last updated: June 24, 2026

This privacy policy governs your use of the mobile application MathZam! (the "Application"). MathZam! is a mathematical integer sequence recognition tool that queries the On-Line Encyclopedia of Integer Sequences (OEIS).

1. Information Collection and Use

We do not collect or request any personal identification information (PII) from users of this Application. However, the Application uses third-party services that may collect information used to identify you:

• Google Play Services: Used to run the Application core services.
• Google AdMob: The free version of the Application displays advertisements served by Google AdMob. AdMob may collect and use advertising identifiers (like Google Advertising ID) and device information to personalize ads and analyze ad performance.
• Google Play Billing: Used to process purchases of the Full Version of the Application. All payment information is securely collected and processed by Google Play. We do not access or store your payment details.

2. Local Data Storage

The Application stores search history, favorites, and user settings locally on your device. This data is not transmitted to our servers or to any third parties (except as part of standard device backups managed by your operating system).

3. External API Queries

When you perform a sequence search, the Application transmits the numerical sequence to the OEIS API to retrieve matching records. No user identifier is attached to these queries.

4. Children's Privacy

The Application does not collect personal information. We do not knowingly target or collect data from children under the age of 13. If you believe your child has provided any personal information, please contact us so we can take immediate action.
