Effective date: October 2, 2026. This policy describes the ad-free Mathbrain version 1.4 developed by Amal Dev S.
Mathbrain is an offline arithmetic game. It does not require an account and does not include advertising, analytics, or tracking SDKs. The app does not send gameplay information or player names to the developer or advertising services.
If you save a high score, the name you enter, your score, and your previous player name are stored in the app's private storage on your device. You can use a nickname and do not need to enter your real name.
Android may include app data in device backups or transfer it to another device, depending on your device and backup settings. These backups are managed by your device's backup provider, not by the developer.
You can remove locally stored scores and names by clearing Mathbrain's storage in Android Settings or uninstalling the app. Manage any backups through your device's backup settings. The app does not currently have a separate reset-high-scores button.
Mathbrain can be played without providing personal information. Player names used for local high scores are optional; children can use a nickname. There are no ads, purchases, or in-app accounts.
The app's rating link opens its Google Play listing. Use of Google Play is governed by Google's own privacy policies.
This policy may be updated when the app's behavior changes. For questions, contact fireworkshopteam@gmail.com.
