Privacy policy
Kamosu saves your moods and notes on your device.
Information stored
Kamosu stores entry dates, moods, optional notes, fermentation kinds and start dates, and finished vessels. If you enable health-based updates, estimates and their dates are also saved on your device.
HealthKit
With your permission, Kamosu reads heart rate and heart rate variability. Raw readings are not stored in your journal file. Journal entries and health data are not sent to the developer’s servers or external AI services. Kamosu does not write to HealthKit.
Ads and external sharing
There are no accounts, ads, analytics SDKs, or public sharing features. Your information is not sold or used for advertising.
Backups
Device backups follow your iOS settings. You can export your journal yourself. Exports include notes and saved health estimates, so choose a destination you control.
Permissions and deletion
Change read permissions in iOS Health settings. Delete daily entries in the app, or remove all health estimates in connection settings. Exported files and device backups must be managed separately.
Widgets
The widget shows the vessel’s appearance, kind, and stage. Notes and mood values are not displayed.
