Privacy

Last updated: 9 November 2026

tsuchi works entirely on your iPhone. We do not collect, store on servers, sell or share any personal data. There are no accounts, no analytics, no advertising and no third-party code. The app does not connect to the internet.

What stays on your device

• Your pieces: their shape, carving and glaze, the names you give them, and a small picture of each, saved in the app's own storage.
• Your settings for sound and touch feedback.

If you use iCloud Backup, iOS may include this data in your personal device backup, which is handled by Apple.

Permissions

tsuchi asks for no access to your photos, camera, microphone, location, contacts or any other personal data. It plays sound through the normal speaker and respects your silent switch, and it uses the haptic motor for touch feedback.

Deleting your data

You can remove any piece from the shelf at any time with "let it go". Deleting tsuchi removes all of its data from your iPhone.
