WristGrid privacy, stated plainly.

Information processed

WristGrid handles these data flows:

HealthKit records (read-only)

HealthKit data is read-only: WristGrid does not write to HealthKit and does not persist HealthKit data in SwiftData. When you grant HealthKit permission, WristGrid reads supported Apple Health records that originate from Garmin for widget features.

Watch data received for widgets

WristGrid receives selected Garmin-native metrics (Body Battery, Stress, Recovery Time, and Move Bar) from a Connect IQ companion on your watch so it can show them in widgets. Watch/GW Bridge data is stored locally in SwiftData to provide a history. Users can export and delete that local history.

Analytics (PostHog)

WristGrid uses PostHog for product analytics. PostHog is configured for the EU cloud, and this analytics data is processed in the EU.

Analytics covers:

• product interaction: which screens and features you use;
• performance data and other diagnostic data;
• a random device identifier that the app generates itself.

Analytics data is not linked to your identity: the app asks for no name, email, or account, and no health values are sent. Analytics is used for analytics and for app functionality and diagnostics only.

It is not used for advertising, we do not track you across other apps or websites, and this data is not sold.

You can opt out of analytics in WristGrid's settings. Opting out stops analytics collection, and it also stops the analytics link to your purchases.

Purchases (RevenueCat)

WristGrid uses RevenueCat to manage subscriptions and purchases. RevenueCat handles purchase history (your subscription and lifetime status) tied to an anonymous app user ID.

That purchase data is used to unlock Premium and keep app functionality working, and for aggregate revenue analytics. Payments are processed by Apple; we never see your card details.

Community notifications

If you turn on community notifications, WristGrid registers a push token from Apple's notification service together with your anonymous app user ID, so it can deliver the updates you asked for. You can turn community notifications off at any time in WristGrid's settings.

This notification data is used only to deliver those updates. It is not used for advertising, and we do not track you across other apps or websites.

Processors

These processors handle the analytics and purchase data described above:

• PostHog: posthog.com/privacy
• RevenueCat: revenuecat.com/privacy

No account is required to use WristGrid, and no account information is requested.

Use and storage

HealthKit access is permissioned by you. Revoking permission stops future reads. The HealthKit flow remains read-only and is not persisted in SwiftData.

The history WristGrid builds from your watch metrics is stored locally on the iPhone in SwiftData. Your health and watch data stays on your device: HealthKit records and Garmin data are read and shown locally in the app and in its widgets, and they are never uploaded to us, to PostHog, or to RevenueCat.

Gurfus does not operate a server that receives your health or watch data. The analytics and purchase data described above are handled by PostHog and RevenueCat as processors, and neither receives your health values.

Your choices

• HealthKit permission: Grant or revoke WristGrid's access to supported HealthKit records using Apple's health permissions controls. Revoking permission stops future reads.
• Local-history export: Use WristGrid's export control to export your local history.
• Local-history deletion: Use WristGrid's delete control to delete your local history from the iPhone. Revoking Garmin or Connect IQ consent does not itself guarantee deletion of local history WristGrid has already stored.
• Analytics opt-out: Turn analytics off in WristGrid's settings. Opting out stops analytics collection, and it also stops the analytics link to your purchases.
• Notification opt-out: Turn community notifications on or off in WristGrid's settings.

Because WristGrid requires no account and Gurfus operates no server that receives your health or watch data, Gurfus cannot access or delete your local history remotely.

Third-party platforms

WristGrid receives selected Garmin-native metrics from a Connect IQ companion on a compatible Garmin device, and can also use supported Garmin-originated records in Apple Health for widgets.

PostHog and RevenueCat process the analytics and purchase data described above on WristGrid's behalf; their own privacy policies are linked in the Information processed section.

WristGrid is an independent product. It is not affiliated with Garmin, and it is not endorsed by or sponsored by Garmin. Garmin, Connect IQ, and Apple Health have their own platform terms and controls; this policy describes WristGrid's behavior only. For the companion that runs on your watch, see the GW Bridge Privacy Policy.

Health Connect

With your permission, WristGrid reads these data types from Health Connect:

• steps
• distance
• active calories burned
• total calories burned
• floors climbed
• heart rate
• sleep
• exercise sessions
• elevation gained
• speed

WristGrid writes nothing to Health Connect.

It also asks for two extra permissions:

• Data from before you installed the app: WristGrid reads data recorded before you installed it, to fill your trends and history.
• Reading in the background: WristGrid reads data while the app is closed, to keep your home screen widgets current.

WristGrid uses only the records that the Garmin Connect app writes to Health Connect. It ignores records from other apps.

How WristGrid uses this data

WristGrid uses Health Connect data only to show it to you: in the home screen widgets, the Home dashboard, the sleep and workout screens and the trends. It uses the data for nothing else.

WristGrid's use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements.

Where this data stays

Health Connect data is processed and stored only on your device, in the app's private storage. It is never sent to our servers or to any third party. It is never used for advertising, never sold and never used for analytics.

The app turns off Android backup, so this data is not included in Android backups.

How to revoke access

You can revoke WristGrid's access at any time in Health Connect settings > App permissions > WristGrid.

Data from your Garmin watch

Stress, Body Battery and other watch data come from the GW Bridge app on your watch. They reach WristGrid through the Garmin Connect app on your phone (Garmin Connect IQ).

WristGrid handles this data on your device exactly like the Health Connect data above. GW Bridge has its own GW Bridge Privacy Policy.

Purchases

The monthly subscription, the free trial and the lifetime purchase go through Google Play Billing. RevenueCat manages them as our service provider.

RevenueCat receives your purchase history and an anonymous app user ID, so it can provide and restore your purchases.

Google handles the payment. We never see your card details. The app has no account and no sign-in.

Usage analytics

WristGrid for Android uses PostHog for usage analytics, in PostHog's EU cloud. It is the same PostHog project as the iPhone app.

Events are tied to an anonymous ID that is never linked to a person. No event contains health data.

The app sends these events:

• the app was installed, updated, opened or sent to the background;
• screen views, by screen name;
• onboarding steps;
• paywall views;
• the outcome of purchases and restores.

RevenueCat also sends its purchase events to PostHog under the same anonymous ID.

IP addresses are discarded, so no location is derived. There is no session replay.

Analytics is on by default. You can turn it off in Settings > Privacy > Usage analytics ("Share anonymous usage analytics"). When it is off, nothing is sent.

Notifications

WristGrid creates two kinds of local notifications on your device. It uses no push service.

• a reminder before your free trial ends;
• an alert when your watch has not synced for a while.

They need Android's notification permission. You can turn them off in Android settings.

What the Android app does not collect or use

• No ads and no advertising ID.
• No crash reporting SDK. We only use Google Play's built-in Android vitals.
• No account, and no name or email inside the app.
• No contacts, photos, files, messages or location.

Your choices on Android

• Health Connect access: Revoke it at any time in Health Connect settings > App permissions > WristGrid.
• Export: In Settings > Privacy, export your data as a JSON file. It goes only where you choose, through the Android share sheet.
• Deletion: In Settings > Privacy, delete the stored history or all local data.
• Uninstall: Uninstalling the app removes all of its data from your device.
• Analytics: Turn it off in Settings > Privacy > Usage analytics.
• Notifications: Turn them off in Android settings.
• Analytics and purchase records: There is no account, so ask us to delete them through the contact on this page.

Service providers and platforms

These service providers handle the analytics and purchase data described above:

• PostHog: posthog.com/privacy
