Butterfly Atlas Privacy Policy

Applies to Butterfly Atlas (com.butterflydex.app). Operated by WS App Studio.

On-device learning records

No account is required. Cards, favorites, missed answers, scores and settings stay on your device. Learning records are not automatically sent to our servers or synchronized between devices.

Advertising and third-party services

Google Mobile Ads SDK may process IP addresses and approximate location, device and app identifiers, ad interactions, crash and performance information for advertising, analytics, performance and fraud prevention. The app applies child-directed and under-age-of-consent treatment, a General content rating and non-personalized ads. App code does not request tracking permission. Non-personalized ads may still process data needed to serve ads.

Backups, restoration and record management

Backups are unencrypted JSON files, downloaded on the web or saved in Documents on mobile. They are accessible through Files on iOS. Restore reads only the selected file. Manage and delete other copies at their saved locations. Resetting records or deleting the app may remove device records.

Permissions and external links

The app does not request location, camera, microphone or contacts access. Android 10 and older may require storage permission for Documents backups. External credit and license links are governed by the destination site's policy.

Contact and corrections

Contact and corrections: support@wsappstudio.com. Include your device model, OS and app version, screen and steps to reproduce. Back up records in Settings before deleting the app. This app is educational and does not provide diagnosis or treatment.
