Privacy Policy
Effective 11 September 2026
In short
Good Eye does not collect, store on a server, sell or share any personal data. There are no accounts, ads, analytics or trackers. The app asks for no device permissions and does not connect to the internet itself.
What stays on your device
To remember your settings and progress between sessions, the game saves a few values in the app's storage on your own device:
- your unit choice (millimetres or inches),
- your screen calibration (pixels per millimetre),
- your best scores, your daily challenge results and your statistics (how far off each guess was),
- whether Good Eye Pro is unlocked on this device.
These values never leave your device. You can delete them at any time by clearing the app's storage or uninstalling the app.
Purchases
Good Eye Pro and tips are sold through Google Play. Google handles the payment under its own terms and privacy policy. The developer receives no payment details from it; the app only receives Google's confirmation that a purchase is valid, and keeps it on your device.
A coupon code you type in the app is checked on your device or against the offers in Google Play. It is not sent to the developer.
