Privacy Policy
Updated August 18, 2026
Data collection
The developer does not collect personal data. The app has no account, advertising, analytics, tracking, or developer-operated server.
On-device processing
Press counts, press duration, level tests, experiment history, achievements, and settings are stored on the user's device. These records are not sent to the developer or third parties.
Apple services
Plus purchases and restoration use Apple's StoreKit. Apple processes payments; the developer does not receive credit-card information.
Deletion
Select Erase All Research Records in Settings to delete local records. Deleting the app also removes its local app data.
