Local app data

Your session values, notes, original imported photos, working previews and measurement records are stored in the app’s local container. The app does not operate an account, backend, developer upload, advertising, analytics or tracking service. It requests no camera or photo-library access; you explicitly select files through the system file picker. App-scoped preferences remember your selected session.

Imports, exports and system services

You choose a file provider and sharing destination. Original image metadata is retained in original source bytes and exports, so review it before sharing. File names, geometry and source hashes are included in your backups. Recipients, cloud providers, iOS backups and the App Store follow their own policies and settings.

Support and website

If you email maga40@naver.com, your email and voluntarily supplied information are used to answer that request. Ask by email to remove support correspondence where retention is not otherwise required. This public company website is hosted by Vercel, which may process normal request and security logs.

Deletion

Confirm deletion of a round or session in the app. Unreferenced photos are removed after the saved index is updated; a photo shared by a duplicated session remains until no saved session uses it. Removing the app through iOS removes its local container. Manage shared files, outside originals and system backups separately.
