Privacy Policy
November 6, 2026
Diurna (“the app”) is developed by fuyuz. This policy explains how the app handles your information. In short: the app never collects your data, stores it on a server or shares it with anyone.
Data we collect
None. There are no accounts, analytics, ads or tracking. We do not receive any information about you or how you use the app.
Data the app uses on your device
- Entries and tracker settings: stored only in a database on your device.
- Widgets: to show the latest value and trend on your home screen, the app hands them to the widget on your device.
- Exported files: JSON and image exports go only to the place or app you choose. On iOS, saving the image to Photos asks for add-only access (the app never reads your photos).
If you use your device’s backup feature (Android backup or iCloud Backup), the app’s data may be included in those backups, depending on your settings. This is a feature of the operating system; neither the app nor we receive that data.
Network
The app does not connect to the internet.
Children
The app collects no information from anyone, including children.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
