Privacy Policy

Last updated: 3 September 2026

Overview

MathGate has no backend. There is no MathGate server, no account to create, and no analytics of any kind. Everything the app stores stays in its own private storage on your phone.

Data We Collect

None. No usage data, no identifiers, no crash reports and no telemetry are sent to us, because there is nowhere for them to be sent.

Data Stored on Your Device

MathGate stores the following in the app's private storage, which Android deletes when you uninstall the app:

- Your Math Academy username
- Your Math Academy password, encrypted with an AES-GCM key held in the Android Keystore. The key cannot be extracted from the device.
- The Math Academy session cookies the app receives when it signs in
- Your chosen blocked apps, your daily reset time, and whether a task has already been found today

Network Connections

The app connects to one place: www.mathacademy.com. It signs in on your behalf and reads the list of tasks you have recently completed, which is what decides whether your apps unlock. Your credentials go only to Math Academy, over HTTPS, exactly as they would if you signed in through their website. Once a completed task is found, the app makes no further requests until the next daily reset.

MathGate is not affiliated with, endorsed by, or connected to Math Academy. Your use of their service remains subject to their own terms and privacy policy.

Permissions

- Accessibility Service: To notice when one of your blocked apps comes to the foreground so the blocking screen can be shown. MathGate reads only which app has appeared. It does not read screen contents, and it has no permission to retrieve window content.
- Internet: To sign in to Math Academy and read your completed tasks.
- Ignore Battery Optimisations: To ask Android not to stop the service, so blocking keeps working.

Children's Privacy

MathGate does not collect personal information from anyone, including children.

Changes to This Policy

If this policy changes, the updated version will be posted on this page with a new "last updated" date.
