Privacy Policy
Effective 14 September 2026
Bias Drill does not collect, store or share any personal data. The app makes no network requests of its own, and everything you do in it stays on your device.
What the app keeps, and where
To remember your place, the app saves a few things in its own storage on your device:
- Your settings: chosen market, context length, flat band, dates and appearance
- Your score, streak, results matrix and recent call log
- How many free calls you have used
- Any weekly CSV files you import
None of this leaves your device. It is not sent to the developer or to anyone else. Deleting the app deletes it, and Reset score on the Score tab clears your results.
Imported files
When you import a CSV, the app reads it once and keeps its price rows on your device. The file is never uploaded.
Purchases
The one-time unlock is sold through Apple's App Store. Apple processes the payment and handles your payment details under Apple's Privacy Policy. The app only asks the App Store whether the unlock has been bought on your Apple Account. The developer never receives your name, email or payment information.
No tracking, analytics or ads
The app contains no analytics, advertising, crash-reporting or other third-party code, and it does not track you across apps or websites.
Children
Because the app collects no data from anyone, it collects none from children.
This website
These pages are hosted on GitHub Pages. They use no cookies, analytics or scripts. GitHub may log visits for security, as described in GitHub's Privacy Statement.
Changes
If this policy changes, the new version will be posted here with a new effective date.
