Hydrion / Privacy and data
Clear facts about Hydrion data.
This page reflects inspected Hydrion source behavior. It avoids absolute privacy promises and distinguishes local app records from optional network requests.
Local app data
Hydrion uses on-device preferences for setup, profile choices, goals, selected units, theme, reminders, hydration records, challenge state, tutorial state, and related derived progress.
Accounts
No account or sign-in system was found in the inspected application dependencies and source. V.1.2.0-shark is designed around local app state.
Location and weather
Weather mode requests location permission and obtains device coordinates. Coordinates are sent to Open-Meteo to request forecast data. Weather assistance is optional and has a manual fallback.
Notifications
Hydrion may request Android notification permission and schedules local reminders. Delivery remains subject to Android and manufacturer battery policies.
Analytics and crash reporting
No Firebase Analytics, Crashlytics, Sentry, or comparable analytics/crash SDK was found in the inspected dependencies. This statement describes the inspected source, not every behavior of Android, GitHub, or Open-Meteo.
External services
Open-Meteo serves optional weather requests. GitHub hosts source, the APK, and Discussions. Opening those services is governed by their own practices.
Deletion
Local profile deletion covers profile information, hydration history, goals, saved containers, Body Metrics, personalized state, challenges and history, Bottle Bingo, reminders, weather cache, and pacing configuration. Operating-system permissions remain controlled in device settings.
Widget privacy
Android and iOS widgets receive privacy-scoped snapshots only. Body measurements, reproductive state, clinician information, location, eligibility details, and raw wake or sleep schedules are excluded.
Website data
The Hydrion product pages add no account form, health-data form, fingerprinting code, advertising SDK, or Hydrion-specific analytics. Hosting infrastructure may still process ordinary web requests.
Health notice: Hydrion supports hydration routines but is not a substitute for individualized medical advice. Hydration needs vary.
Release basis: Hydrion 1.2.0+4. Profile deletion covers local profile, hydration, goal, metrics, challenge, reminder, weather, pacing, and widget-related state as disclosed by the application.
