Privacy
Personal records stay under the user’s control.
Offline by design
Apps are designed for local use and user-controlled data.
Hydration – Only the App
The Hydration app has no internet permission and cannot use mobile data or Wi‑Fi. Tracking, calculations, analytics, badges, reminders, drink definitions, settings, and database storage remain on the device. Native operating-system share functions may pass a user-selected item to another app; that other app operates independently.
