Privacy Policy for Hold: Train Healthier

Last updated: 16 June 2026

Hold ("the app") is designed to keep your data on your device. We do not run
servers, we do not operate analytics, and we do not collect, sell, or share
your personal information. This policy explains what the app accesses and why.

Summary

- No data leaves your device to us or any third party.
- No accounts, no tracking, no advertising, no analytics.
- Health and workout data are used only on your device to show your heart-rate
  zones.
- Workouts you track on your Apple Watch are saved to Apple Health on your
  device, and only when you choose to keep them.
- Your location is used only during outdoor workouts, on your device, to
  record your route.

Information the app accesses

Apple Health (read). With your permission, Hold reads your date of birth,
biological sex, and resting heart rate to calculate your maximum heart rate
and personalized training zones. This data is read on demand, used only for
that calculation on your device, and never stored on a server or transmitted
to us. You can grant or revoke this access at any time in the iOS Settings app
under Privacy & Security > Health.

Apple Health (write). With your permission, when you finish a workout on your
Apple Watch and choose to save it, Hold writes that workout to Apple Health:
the workout type you picked, your heart rate, duration, active calories, and
distance, plus your route for outdoor workouts. This is the same kind of
record the built-in Workout app creates. It stays in Apple Health under
Apple's health-data protections and is never transmitted to us. You can revoke
write access at any time in the iOS Settings app, and you can view or delete
saved workouts in the Health app.

Location. Hold uses your location only during outdoor workouts started on your
Apple Watch, to record your route and distance. Location is read only while
the workout is running, saved solely as part of that workout in Apple Health,
and never transmitted anywhere. Indoor workouts never access your location.
You can grant or revoke this access at any time in Settings.

Bluetooth. Hold connects to your heart-rate sensor over Bluetooth to read your
live heart rate during workouts. The name and identifier of sensors you pair
are stored locally so the app can reconnect to them. This information is not
transmitted anywhere.

Workout sessions. Heart-rate samples and workout summaries you record are
stored locally on your device. They remain there and are included in your
device backups if you have those enabled (for example, iCloud or encrypted
local backups managed by Apple); we never receive them. During a workout, data
travels directly between your Apple Watch and iPhone and is never routed
through a server.

App settings. Preferences such as your chosen theme are stored locally on your
device.

Purchases

Hold offers optional in-app tips to support development. Purchases are
processed entirely by Apple through the App Store. We do not receive your
name, payment details, or any other personal information from these
transactions; the only thing we see is an anonymous confirmation that a
purchase completed.
Apple's handling of payment information is governed by Apple's own privacy
policy.

Data sharing

We do not share your information with any third party, because we never
collect it in the first place. The app contains no third-party analytics,
advertising, or tracking software, and does not track you across other apps
or websites.

Data retention and deletion

Everything the app creates or accesses stays on your device. To delete the
app's own data, uninstall the app. Workouts you saved to Apple Health are part
of your Health data and remain there after uninstalling; you can view or
delete them at any time in the Health app. To revoke Health, Location, or
Bluetooth permissions without uninstalling, use the iOS Settings app.

Changes to this policy

If this policy changes, the updated version will be posted at this same
location with a revised "Last updated" date.
