Data Handling

Oalculator does not collect, upload, sell, or share personal data. The app requires no account and contains no advertising, analytics, or third-party tracking services.

On-device Data

Data such as your appearance mode and typewriter sheets is stored only on your device. The app does not send this information to the developer.

System Permissions

Oalculator asks for permission to add images to Photos only when you choose Save Image in the share sheet, and it cannot read your photo library. It does not request access to Camera, Microphone, Location, Contacts, or other personal data.

Deletion and Retention

Uninstalling the app removes its local data. System backups and device migration are governed by your Apple system settings.
