Mastishka — Privacy Policy
Last updated: 21 August 2026
Mastishka ("the app") is developed by Vishnu Vijayakumar V ("we"). This policy explains what
data the app handles and how.
Data we collect
- Gameplay data (scores, levels, achievements, settings) is stored locally on
your device only. We have no account system and no server that stores your progress.
- Analytics. The app uses Google Firebase Analytics and Crashlytics to collect
anonymous usage statistics (e.g. which challenges are played) and crash reports (device model,
OS version, stack traces). This helps us fix bugs and improve the game.
- Advertising. The free version shows ads served by Google AdMob. AdMob may
use your device's advertising ID to serve and measure ads. In the EEA/UK you are asked for
consent before personalised ads are shown, and you can change your choice any time in
Settings → Privacy Settings.
- Purchases. The optional one-time Premium purchase is processed entirely by
Google Play. We never see your payment details.
What we do NOT collect
- No name, email address, contacts, location, photos, or files.
- No account registration of any kind.
Third-party services
These partners process data as described in their own policies:
Children
The app is a general-audience brain game and does not knowingly collect personal information
from children. Brain Score and skill statistics are game metrics only — they are not medical,
psychological, or scientific measurements.
Data deletion
All gameplay data lives on your device: uninstalling the app deletes it. To request deletion of
analytics data associated with your device, contact us at the address below.
