StayHydro does not sell your personal information.
StayHydro stores app-related information locally on your device, such as:

StayHydro uses notifications to provide hydration reminders, custom schedule reminders and special reminders configured by the user.
Notification permission is used only to deliver reminders and app-related alerts.
StayHydro uses Google Firebase services to help improve app reliability and performance.
These services may include:
- Firebase Analytics
- Firebase Crashlytics
- Firebase Cloud Messaging
Firebase Analytics may collect app usage and performance information to help us understand how the app is used and improve the user experience.
Firebase Crashlytics may collect crash reports, device information, app version, operating system information and diagnostic data when the app crashes or experiences errors.
Firebase Cloud Messaging may be used to support notification-related functionality.
These services are provided by Google and may process information according to Google’s own privacy and data policies.
StayHydro may use internet access for Firebase services, analytics, crash reporting and future app improvements.
StayHydro does not use internet access to upload your personal hydration logs to a Slnova server.
StayHydro does not currently include advertising.
In the future, StayHydro may introduce advertisements using services such as Google AdMob.
If advertising is added in a future version, this Privacy Policy and the Google Play Data Safety information will be updated before or at the time such features are released.
We do not sell your personal data.
We do not share your locally stored hydration history with third parties.
Limited technical data may be processed by Google Firebase services for analytics, crash reporting and app reliability purposes.
Hydration logs, settings and preferences remain stored on your device until you delete the app data, uninstall the app or reset the app.
Crash and analytics data handled by Firebase is managed according to Google Firebase retention practices.
You can delete locally stored StayHydro data by:
- Clearing the app data from Android settings
- Uninstalling the app
If you contact us for support, we may receive your email address and any information you choose to include in your message.
StayHydro is suitable for general audiences but is not specifically intended for children under 13.
We do not knowingly collect personal information from children under 13.
StayHydro is designed to support healthy hydration habits and reminder routines.
StayHydro does not provide medical advice, diagnosis or treatment.
Users should decide their water intake based on their own needs, lifestyle and medical guidance where appropriate.
We aim to keep StayHydro simple and privacy-friendly by storing hydration data locally on the user’s device.
However, no digital system can be guaranteed to be completely secure.
We may update this Privacy Policy from time to time.
Any changes will be reflected by updating the effective date above.
