Sprint

Privacy policy

This policy covers Sprint for iPhone and Apple Watch. It is short because Sprint does very little with your data: there are no accounts, no analytics, no advertising and no servers of ours. Your training stays on your devices and in your own iCloud. The only thing Sprint asks another service for is the weather, and that service is Apple’s.

What Sprint stores

Everything Sprint stores comes from you, or from your Watch while you train. None of it is sent to us.

  • Your sessions. When you trained, the name you gave the place, whether it was a track or the street, each sprint’s distance, time and speed, your rests, the GPS route, and the weather when you started.
  • Health data from your sessions. Your heart rate, the active energy you burned, each sprint’s peak heart rate and recovery, and your heart rate at the start and end of each rest.
  • Your plans, and the sessions you schedule.
  • Your settings. Units, the distances you use, rest and reminder choices and, if you type one, the name Home greets you by.

What Sprint asks to use

Sprint asks permission before it uses each of these, and uses them only to run the app.

  • Apple Health. Sprint asks to read your workouts and their routes, heart rate, active energy, walking and running distance, heart-rate variability, resting heart rate, respiratory rate, sleep, VO₂ max and date of birth. It asks to write workouts and their routes, heart rate, active energy, and walking and running distance. Your Watch asks only for what it records during a session.
    • Your Watch saves each session to Apple Health as a workout. Sprint reads back only the workouts it saved itself.
    • The other readings are for your readiness score, your cardio fitness and your heart-rate zones (your date of birth gives an estimate of your maximum heart rate). Sprint doesn’t save those readings itself.
  • Location. Your Watch uses GPS while a session runs, to measure each sprint’s distance and speed and to record the route. Your iPhone asks for one location, to about 100 metres, while you are using the app, to show the weather where you are.
  • Calendar. If you ask for planned sessions to appear in your calendar, Sprint adds events (title, date, time, length and place, if any) to your default calendar. It has write-only access: it can add events but can’t read your calendar.
  • Notifications. Sprint reminds you of planned sessions. The reminders are scheduled on your device.

While a session runs, your Watch also reads its motion sensors to tell when each sprint ends. This doesn’t need your permission. Sprint doesn’t save the raw readings, only the times and distances worked out from them.

Where it lives

  • On your devices. Your iPhone, and your iPad if you use one, keep everything described above. Your Watch keeps your 10 most recent sessions, and any older one until your iPhone has confirmed it received it. Sprint keeps your data until you delete it.
  • Health data stays on each device. Your heart rate and active energy from a session are never put in iCloud. A second device, such as an iPad, rebuilds them from the session’s workout in Apple Health, so it needs your permission to read Health.
  • In your own iCloud. Your sessions (everything above except the heart rate and active energy, so including the GPS route and the weather), your plans and your scheduled sessions sync between your iPhone and iPad through your private iCloud storage. It belongs to your Apple Account and counts towards your iCloud storage, and we can’t see it.
  • In Apple Health. The workouts your Watch saves live in Apple Health and follow your Health settings.
  • In your calendar, if you ask for it, as described above.

What leaves your device

Sprint sends information off your device only to Apple, to do something you asked for.

  • Apple Weather. To show the weather, Sprint sends coordinates to Apple Weather. For the weather now, that is your iPhone’s current location, while Home is showing it and you have allowed location. For the weather at a past session, it is a point in the middle of that session’s route and the time the session started. Sprint keeps the weather it gets back with the session. Apple says it uses location only to provide weather forecasts and doesn’t tie it to personal information.
  • Apple Maps. The maps in Sprint are Apple Maps.
  • iCloud, Apple Health and your Watch. Syncing with iCloud and saving to Apple Health are done by Apple, as described above. Your iPhone and Watch share data directly with each other.

Apple handles all of this under Apple’s privacy policy. We don’t receive any of it.

We don’t share your information with anyone else. Sprint contains no third-party analytics, advertising or other third-party code that can see your data.

What we never do

  • We never ask you to create an account or sign in.
  • We never show advertising, and we never track you. Sprint doesn’t follow you across other companies’ apps and websites, and doesn’t link your data with theirs.
  • We never sell your data, or give it to data brokers or advertising networks.
  • We never use your Apple Health data for advertising, marketing or data mining, and we never pass it to anyone else.
  • We don’t use analytics or crash reporting.

Your choices

  • Turn off a permission. You can allow or refuse Health, location, calendar and notifications separately, and change your mind at any time. Use Settings on your iPhone, under Privacy & Security, or the Health app’s sharing settings for Health. Sprint’s own Settings has a Permissions page that shows where each one stands and opens Settings for you. Some features need a permission: for example, readiness needs Health, and the weather where you are needs location.
  • Delete your data. In Sprint, choose Settings, then Delete all data. It removes your sessions, plans and scheduled sessions from your iPhone, your Watch and iCloud. You can also delete a single session. Some things stay, because they belong to other apps or to the system:
    • Workouts already saved in Apple Health. Delete them in the Health app.
    • Events already added to your calendar. Delete them in Calendar.
    • Your settings on that device, until you delete the app.
    • For each deleted session, a small marker (its ID, its start and end times, and when it was deleted) stays in your iCloud, so your other devices know to remove it too.
  • Turn off iCloud sync. Sprint has no switch of its own for this. Turn off Sprint’s access to iCloud in Settings on your iPhone, in your Apple Account’s iCloud settings. Your sessions and plans then stay on each device separately. Copies already in iCloud stay there until you delete them, so use Delete all data first if you want them removed.
  • Take your sessions with you. In Settings, choose Export sessions for a CSV file of your sprints and a GPX file of your routes.
  • Questions or requests. We don’t hold your data, so there is nothing on our side to look up or delete. If you have a question, contact us using the details below.

Children

Sprint isn’t made for children, and it doesn’t ask for your age. If Apple Health has your date of birth, Sprint uses it on your device to estimate your maximum heart rate. Because Sprint has no accounts and sends no personal information to us, we don’t collect information from children, or from anyone else.

Changes to this policy

If what Sprint does with your data changes, we will update this page.
