Privacy policy
Last updated: 9 November 2026
Your health data and your scores stay on your iPhone. Throttle has no account and no server, and it does not collect your data.
Who is responsible
Throttle is made by an independent developer in the Netherlands, named as the seller on the App Store page. For questions about this policy, email info@throttle.health.
Data on your devices
- Health and workout data. With your permission, Throttle reads the types of data you allow from Apple Health, to calculate your scores and show your workouts. You choose which types.
- Scores and results. Throttle calculates them on your iPhone and keeps them in local storage on your iPhone. They are left out of device backups and rebuilt from Apple Health when needed.
- What you enter yourself. Throttle writes it to Apple Health where Apple Health has a place for it. Anything else, such as your goals, stays in local storage on your iPhone.
- Apple Watch. Your iPhone sends results to the Throttle app on your Apple Watch.
- Settings. Settings that hold no health information can sync between your devices through your own iCloud account.
Throttle uses this data only to show you your own values. Health data is never used for advertising, marketing or data mining, and it is never stored by Throttle in iCloud.
What leaves your iPhone
Maps and weather need Apple's services. Only what those services need is sent, and only to Apple. No health data is sent with these requests, and Throttle does not receive this information.
| Feature | What Apple receives | When |
|---|---|---|
| Map of a workout route | The map area being viewed | While you view the map |
| Daily weather | Your approximate location | At most once an hour while the app is open, only if you allow location access |
| Weather of a workout with a route | The start of the route, rounded to about 1 km, and the hour of the workout | When you open the workout |
Weather data from Apple is shown only. It is kept in memory and not stored. Apple handles these requests under its own privacy policy.
Subscription
Apple handles your subscription and your payment. Your purchase is verified on your iPhone. Throttle does not receive your payment details.
What Throttle does not do
- No account or sign-in.
- No server of its own that holds your data.
- No analytics, ads or tracking.
- No crash reporting that sends data off your device. If you choose in iOS to share analytics with app developers, Apple can pass on crash reports without your health data.
- No artificial intelligence services in the cloud.
- No selling or sharing of your data.
Sharing with others
Apple is the only third party that receives data from the app, as described above, and it provides the same or equal protection of that data as this policy.
How long data is kept, and how to remove it
- Data stored by Throttle stays on your iPhone until you delete the app. Deleting the app removes it.
- You can withdraw access to Apple Health at any time in iOS Settings, under Privacy & Security, Health.
- You can withdraw location access at any time in iOS Settings, under Privacy & Security, Location Services.
- Data in Apple Health stays in Apple Health. You manage and delete it there.
Because this data is only on your devices, Throttle cannot see it, hand it over or delete it for you.
This website
This site has no cookies, analytics or forms. It is hosted on GitHub Pages. GitHub logs the IP address of visitors for security, under its own privacy statement.
When you email support
Your email reaches Throttle through an email forwarding service. Your email address and your message are used only to answer you, and kept only as long as needed for that. Please do not send health data.
Your rights
If you live in the European Union, you can ask for access to, correction of or deletion of personal data that Throttle holds about you, such as a support email, and you can object to its use. Email info@throttle.health. You can also file a complaint with your data protection authority, in the Netherlands the Autoriteit Persoonsgegevens.
Changes
When this policy changes, the new version appears on this page with a new date.
Throttle gives insights for training and recovery. It is not medical advice.
