WristGrid privacy, stated plainly.

This policy explains the information the WristGrid iPhone app handles to present your Garmin metrics in iPhone widgets, together with the limited analytics and purchase data described below.

  • Effective date: September 25, 2026
  • Last updated: October 20, 2026

Scope

This Privacy Policy describes how the WristGrid iPhone app handles information to show your Garmin metrics in iPhone widgets, and the limited analytics and purchase data it uses. WristGrid works alongside a Connect IQ companion on your watch, but that companion has its own policy.

It covers supported Garmin-originated Apple Health records, the Garmin-native metrics WristGrid receives for its widgets, app analytics, and purchase status. It does not govern Garmin, Connect IQ, or Apple Health themselves.

Looking for the watch companion? See the GW Bridge Privacy Policy; it covers what the Connect IQ app collects on your Garmin device and how it sends data to WristGrid.

WristGrid is available on the App Store. The App Store product page carries Apple's own privacy labels for the app, including its analytics and purchase data; this page remains the full, dated policy.

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:

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.

Support requests

When you contact WristGrid support, you choose what to send. That can be a message and, optionally, screenshots, photos, or videos that you attach.

We use what you send only to answer your request.

Waitlist

If you join the WristGrid for Android waitlist, we collect your email address only. We use it to send one email when WristGrid is available for Android, and then we delete it.

Your waitlist email is stored in a self-hosted database on our own server. It is never sold or shared, and it is not linked to analytics or advertising profiles. No analytics SDK is used for the waitlist form.

To leave the waitlist or request deletion, email hello@gurfus.dev.

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.

Policy updates

This policy may be updated when the WristGrid product changes. The current version is published on this page with its effective date.
