Privacy Policy

Last updated: April 5, 2026

MateProf ("the App") is a math education app developed by Duta Viorel-Ionut ("we", "us", "our"). We are committed to protecting your privacy. This Privacy Policy explains what information is collected and how it is used.

1. Information We Collect

We do not collect, store, or transmit any personal information. All your learning progress is stored locally on your device and is never sent to our servers.

2. Locally Stored Data

The App stores the following data on your device only:

• Lesson completion progress
• Experience points (XP) and streak counts
• Badge achievements
• App preferences

This data remains on your device and is not accessible to us or any third party.

3. Third-Party Services

The App uses Google AdMob to display advertisements. Google AdMob may collect certain data to serve ads, including:

• Device identifiers (e.g., advertising ID)
• IP address
• General location (country/region level)
• App usage data for ad performance measurement

For more information on how Google handles data, please review Google's Privacy Policy and Google AdMob's data practices.

4. Children's Privacy

The App is an educational tool and does not knowingly collect personal information from children. All data is stored locally on the device.

5. Data Sharing

We do not sell, trade, or share any user data with third parties. The only third-party service used is Google AdMob for advertisement delivery as described above.

6. Data Security

Since all user data is stored locally on your device, it is protected by your device's built-in security features. No data is transmitted over the internet by the App itself.

7. Your Rights

You can delete all locally stored data at any time by uninstalling the App from your device.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date.
