Sprint

Terms of use

These terms cover your use of Sprint for iPhone and Apple Watch. They are short because Sprint is a simple app: no accounts, no advertising and no servers of ours. Please read them before you train with it.

Last updated 11 October 2026.

In short

  • Sprint is a training tool. It is not medical advice, and you train at your own risk.
  • Distances, speeds, heart-rate zones and wind readings are estimates. They are not official measurements.
  • Your sessions are yours. They stay on your devices and in your own iCloud.
  • Apple’s standard licence sets the warranty and liability terms. Nothing here takes away your legal rights.

1. Using Sprint

Apple’s standard licence for apps (the Licensed Application End User License Agreement) is the licence for Sprint. It sets the terms between you and us on warranty, liability, ending the licence and which law applies. These terms add to it and cover what is particular to Sprint. If the two disagree on the same point, Apple’s licence comes first.

You can use Sprint for your own training, on iPhone and Apple Watch, for as long as you have it installed. There is no account to create. Recording a session needs an Apple Watch; the iPhone shows it live and keeps your history. Sprint isn’t made for children.

2. Training safely

Sprinting is hard on the body. Sprint doesn’t give medical advice, and nothing in it, including your readiness score, heart-rate zones, recovery numbers or cardio fitness, is a diagnosis or a reason to train, or not to train. If you have a health condition, or you’re unsure whether intense exercise is right for you, talk to a doctor first.

  • Choose a surface and a place that are safe, and warm up properly.
  • Look where you’re running, not at your wrist or your phone.
  • Stop if you feel unwell. A plan in the app is never a reason to push on.

You are responsible for how you train and for the places you train in.

3. Estimates, not measurements

Sprint works out distance and speed from your Watch’s GPS and motion sensors. These can be wrong, especially near buildings, trees or stands, or on a short straight. The wind comes from a weather forecast from Apple Weather, not from an instrument beside your track. The wind-legal warning is a guide to whether a day is fast, not an official reading.

Don’t use Sprint’s times, distances or wind figures as proof of a performance, or for a record, a ranking, a selection or a competition result. Use the timing and wind equipment the event provides.

4. Your data

Your sessions, plans and settings stay on your devices, and in your own iCloud if you use more than one. We don’t receive them. The privacy policy says exactly what Sprint stores and what leaves your device, and it forms part of these terms.

You are responsible for your own backups. If you delete a session, or choose Delete all data, it can’t be recovered through us, because we don’t have a copy. You can export your sessions at any time from Settings.

5. Apple’s services

Sprint relies on services that Apple runs: Apple Weather, Apple Maps, iCloud and Apple Health. They are not ours, and they can change, be unavailable or be turned off by you. When they are, parts of Sprint will not work. Your use of those services is covered by Apple’s own terms.

6. Who owns what

Sprint, including its design, text, code and name, belongs to its maker, Dan Lages, and these terms don’t transfer any of it to you beyond the right to use the app. What you record in Sprint is yours, and we claim no rights to it.

7. What you agree not to do

  • Copy, resell or redistribute the app, or pass it off as your own.
  • Take the app apart, or try to get at its code, except where the law lets you.
  • Use Sprint in a way that is unlawful or puts other people at risk.

8. Warranty and liability

The disclaimer of warranties and the limits on our liability are in Apple’s licence, and they apply to Sprint. We work to make Sprint accurate and reliable, but you use it at your own risk, and sections 2 and 3 explain why its figures can’t be relied on as exact.

Where the law doesn’t allow a limit, including for death or personal injury caused by negligence, the limit doesn’t apply. Nothing in these terms affects your statutory rights as a consumer.

9. Changes and ending

If we change these terms, we will update this page and its date. By continuing to use Sprint after a change, you accept it. You can stop at any time by deleting the app. We may stop offering Sprint, in whole or in part, and if we do we will say so here.
