Privacy Policy

Last updated: September 14, 2026 · GroveRhythm for iOS

GroveRhythm keeps everything on your device. There is no account, no server of ours to sync with, and no third-party analytics or advertising code in the app. This page explains exactly what that means.

1. Summary

• GroveRhythm does not require an account.
• Practice, water, breathing and settings data are stored on your device.
• The app contains no third-party analytics, advertising or attribution SDKs.
• The app makes no network requests of its own.
• We do not sell personal data.
• Optional system features: Notifications and Live Activities.

2. Information we process

2.1 Data stored on your device

The app may store the following locally, for example via UserDefaults or other on-device storage. This information is not uploaded to our servers, because we do not operate one.

This data is used only to provide app features: timers, reminders, statistics and the Live Activity display.

2.2 Data we do not collect

We do not collect:

• Name, email address, phone number or account credentials
• Precise or approximate location
• Photos, contacts, microphone or HealthKit data
• Advertising identifiers (IDFA). The app does not present an App Tracking Transparency prompt because it does not track you.
• Payment card details. The current version has no in-app purchases.

If you email us for support, we receive the address and the content you send. We use that only to answer your request.

3. Permissions and system features

3.1 Notifications

If you allow notifications, the app may send local alerts for:

• The end of a practice session
• Mid-session rhythm cues (water, breath, rest)
• Daily water reminders
• Scheduled plan reminders

Notification content is generated on your device. Nothing is sent through a push server. You can revoke the permission at any time in iOS Settings; plans still appear on the calendar, they simply will not alert you.

3.2 Live Activities

During an active session the app may show a Live Activity on the Lock Screen or in the Dynamic Island with the remaining time and the current rhythm state. This uses Apple's ActivityKit on your device.

3.3 Haptics

Optional haptic feedback runs locally for interactions and session events.

4. How the data is used

On-device data is used to:

• Run timers and rhythm breaks during a practice
• Show progress, history, achievements and weekly insights
• Schedule the local reminders you configure
• Restore an interrupted session

It is never used for advertising or cross-app tracking.

5. Sharing

We do not sell or rent your data, and we do not share practice, water or breathing records with third parties.

Data may be processed by Apple as part of the iOS system services you enable — for example delivering local notifications or rendering Live Activities — under Apple's own terms and privacy practices.

6. Retention and deletion

Data stays on your device until you delete it or remove the app. You can:

• Delete individual records or plans inside the app
• Offload or delete the app, which removes its local storage

There is no cloud account to request remote deletion from, because we do not host your practice data. If you have written to us by email, you may ask us to delete that correspondence.

7. Children

The app is not directed at children under 14, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, contact us and we will help you remove local data as applicable.

8. International users

The app stores data locally on the device where it is installed. We do not transfer your practice data across borders, because we do not transfer it at all.

9. Changes to this policy

We may update this policy from time to time. The “Last updated” date above will change when we do. Continued use of the app after an update means you accept the revised policy. Material changes will be reflected in the App Store listing or as an in-app notice where required.
