Privacy Policy
Last updated: September 24, 2026
In short: the GRX Offline Workout app does not collect any data. It works 100% offline, and your data never leaves your devices except through your own iCloud.
1. The app collects nothing
The app does not connect to the internet and does not transmit any data over the internet. There is no account, no sign-up, no analytics, no ads and no trackers.
Grx Labs does not receive any information about you or about how you use the app.
2. Where your data is stored
Your workouts, history and preferences are saved only on your device and, if you turn on sync, in your own iCloud account, under Apple's privacy policy.
Heart rate and calories from Apple Watch are read from and saved to the Health app on your own device.
3. We have no access
Grx Labs cannot view, change, recover or delete your data. It exists only on your devices and in your iCloud.
4. Deleting your data
You can delete your data at any time: with the reset option in the app's Settings, by deleting the app, or by removing the app's data from iCloud in your device settings.
5. This website
This website does not ask for personal data. With your consent, it may use cookies from PostHog (usage analytics) and Vercel (hosting and performance statistics) to understand how the site is used.
You can accept or decline in the cookie banner and change your choice at any time in "Cookie preferences" at the bottom of the page. Declining does not affect the site.
6. Changes
If this policy changes, we will update this page and the date at the top.
