Privacy Policy
Last updated: September 7, 2026
Your Privacy Matters
Mentalism Mastery, published by Rizwan Shoaib, is designed with your privacy as a priority. Your learning content stays on your device. The app is free and supported by ads served through Google AdMob, described below.
Data Storage
- All your lesson progress, notes, favorites, and preferences are stored locally on your device.
- No user account or registration is required.
- We never sell your personal learning data. The one exception is our advertising partner, Google AdMob, which collects limited device data to show ads — see “Advertising” below.
Advertising
Mentalism Mastery is free and supported by ads. We use Google AdMob to display banner and occasional full-screen (interstitial) ads.
- To serve and measure ads, Google AdMob may collect device identifiers (including an advertising ID) and usage data, as described in Google’s Privacy Policy and Google’s advertising policies.
- In the EEA, UK, and Switzerland we show a consent prompt (Google’s User Messaging Platform) before any personalized ads are requested. You can decline personalized ads there.
- You can also reset or opt out of your advertising ID at any time from your device settings (Settings → Google → Ads).
- We do not share your lesson progress, notes, or any personal information you enter into the app with advertisers.
Analytics & Crash Reporting
Besides advertising, the app uses the following Google services so we can keep it working and improve it:
- Google Analytics for Firebase — usage analytics showing which features are used and whether the app is healthy. It collects an app-instance identifier and the advertising ID, app-interaction events (screens opened, sessions), coarse device information, and an approximate location derived from your IP address.
- Firebase Crashlytics — crash reporting. It collects stack traces, the app state at the moment of a crash, device metadata and a Crashlytics installation identifier, so we can find and fix faults.
Google acts as our service provider for these. The data is used to run and improve the app; it is not sold, and it is not shared with advertisers. It is separate from the advertising data described above.
Permissions
- Notifications — Used only for practice reminders you choose to enable.
- Vibration — Used for haptic feedback on interactions.
- Internet — Used to load content updates and to load ads from Google AdMob.
Data Deletion
You can reset all locally stored data at any time from the app's settings. Uninstalling the app also removes all locally stored data. You can reset or delete your advertising ID at any time from your device settings (Settings → Google → Ads). If you have questions about advertising data, contact us at the email below.
Children's Privacy
Mentalism Mastery is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us information, please contact us so we can address it.
Changes to This Policy
We may update this privacy policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Continued use of the app after changes are posted constitutes acceptance of the updated policy.
