Privacy Policy

Last updated: September 26, 2026

This Privacy Policy sets out how StackWorks (“we” or “us”) handles users' information in the iPhone app Gym Note (the “App”).

1. Information We Collect

We do not collect users' personal information through the App. The App has no account registration, advertising, analytics or tracking.

2. Information Stored on Your Device

Your workout records (such as dates and times, exercises, weights and reps), routines and settings are stored only on your iPhone. They are never sent to our servers. This data is included in your iPhone's backups. If you delete the App, your records are deleted as well.

3. Apple Health (HealthKit)

Only when you turn on Settings > Save to Health does the App write your finished workouts to the Health app as strength training workouts, along with their start and end times. The App does not read any data from the Health app. We never use information obtained from the Health app for advertising or marketing, or provide it to third parties.

4. Notifications and Live Activities

The notification that tells you when your rest is over and the Live Activity on your Lock Screen are created on your iPhone. The App does not use notifications sent from external servers (push notifications).

5. Purchases

Purchases of Gym Note Plus are made through Apple's App Store. We do not receive your payment information. The App communicates with the App Store only to check whether you have made a purchase.

6. CSV Export

When you export a CSV file, it is passed to the destination you choose to save or share it to. How it is handled there is governed by the terms of that destination.

7. Changes

If we change this policy, we will announce it on this page.
