Hydrate: Water Coach is designed as a local-first hydration utility. This policy explains what information the app may process and how that information is used.
Information processed by the app
- Hydration records: Drink amounts, drink types, timestamps, notes, daily goals, streaks, achievements, and related summaries.
- Preferences: Units, quick-add amounts, reminder settings, theme choices, calibration inputs, and onboarding state.
- Apple Health data: If you grant permission, the app can read and write water and caffeine entries. Workout-aware recommendations can read workout data when enabled.
- Location and weather: If you enable weather-aware recommendations, your location is used to request local weather conditions from Apple WeatherKit for hydration adjustment.
- Purchase status: StoreKit is used to determine whether you have active access through a subscription or lifetime purchase.
How information is used
The app uses this information to show daily progress, calibrate goals, schedule reminders, produce reports, restore purchases, sync optional Apple Health records, and export data when you request it.
Storage and sharing
Hydration records are stored locally on your device. There is no account, and the app does not upload your records to a DuttLabs server or a cloud database. The app does not sell personal data and does not include advertising or third-party analytics SDKs. Data leaves the device only when you choose to export it, write selected records to Apple Health, request weather for weather-aware goals, or use a system service that you enable.
Apple Watch
Entries logged on Apple Watch are sent to your paired iPhone using Apple’s Watch Connectivity framework so both devices show the same progress.
Apple Health
Apple Health access is optional. You control Health permissions in iOS Settings and may revoke them at any time. Health data is used only for hydration, caffeine, and workout-aware features.
Notifications
Reminder notifications are optional. Notification permission can be changed in iOS Settings. Smart reminder logic runs on device and uses your local progress and preferences.
Data deletion
You can delete all app data from Settings inside Hydrate, or by deleting the app from your device. Apple Health records are managed separately through Apple Health.
Children
The app is a general wellness utility. We do not knowingly collect personal information from children under 13.
Changes
We may update this policy when the app changes. Updates will be posted on this page with a revised date.
