Privacy policy
Last updated: 2 November 2026
Controller
Loop is an app developed by Víctor Redondo Vargas. For any privacy question you can write to moc.duolci@ved.odnoderv.
Health and workout data
With your permission, Loop reads and saves your workouts, heart rate, energy, distance and steps in the Health app. This data stays on your iPhone, your Apple Watch and your iCloud according to your Health settings: Loop doesn't send it to any server, doesn't share it with anyone and doesn't use it for advertising. You can withdraw permission at any time in Health → your profile → Apps → Loop.
Bluetooth
Loop uses Bluetooth only to connect to your treadmill, read its speed, distance, time and steps, and send it speed changes. It remembers your treadmill on the device so it can reconnect automatically.
Settings
Your settings (units, language, auto start…) are stored on the device and synced between your iPhone and your Apple Watch over the connection between them.
No accounts, no tracking
Loop has no sign-up or accounts, includes no advertising or analytics tools, and doesn't track you across other apps or websites.
Contact form
If you use the contact form, an email is prepared with your name, your email address, your treadmill's brand and model, whether it works with Loop, your message and the Loop and iOS versions. You send it yourself from your email app to moc.duolci@ved.odnoderv. This data is only used to reply to you, try to make your treadmill work with Loop and write to you about it. The legal basis is your consent, which you give by ticking the box in the form and can withdraw at any time.
How long it is kept
Emails are kept while your question is being handled and for at most two years, so we can let you know if your treadmill becomes compatible. After that they are deleted. You can ask for them to be deleted sooner at any time.
Who it is shared with
No one. Emails are received in an iCloud Mail account, an Apple service that acts only as the email provider.
Your rights
You can request access to your data, its rectification, erasure, restriction or portability, or object to its use, by writing to moc.duolci@ved.odnoderv. If you think it hasn't been handled correctly, you can file a complaint with the Spanish Data Protection Agency (aepd.es).
Minors
The form is not intended for children under 14. If you are younger, ask an adult to send it for you.
Changes
If this policy changes, the new version will appear here with its update date.
