Privacy

Last updated: 14 November 2026

Sumi works entirely on your iPhone or iPad. 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 paintings: the ink on each sheet, the titles and notes you write, your seal, and a small picture of each, saved in the app's own storage.
• Your settings, such as sound, haptics and whether guides are shown.

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

Permissions

Sumi 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.

Sharing a painting

When you choose Share, iOS shows its standard share sheet and you decide where the image goes. Sumi does not see or keep anything you send.

Deleting your data

You can delete any painting from your journal at any time. Deleting Sumi removes all of its data from your device.
