PRIVACY

Who this is for

This page explains what Sprinter stores and who can see it. The person responsible for that data is Bastian Sønnichsen. Write to naitsab.larc@gmail.com with any privacy question. Sprinter is not for children under 13. Don't make an account if you are under 13. If a child under 13 has an account, email that address and the account will be deleted.

Why it is stored

Sprinter keeps an account, and the drills you choose to share, because that is the service you signed up for. Camera, microphone, photos, location, and a link to a nearby phone are used only while you use those parts of the app. This website does not use cookies, ads, or analytics.

Account details

When you create an account, Sprinter stores your email, display name, username, account number, and the sports you pick. You can also add a short bio. If you sign in with Apple or Google, Sprinter receives the name and email those services share. Your password is handled by the sign-in service. It is not stored in a form other people can read, and it is not shown in the app. Your email is stored separately from the public profile.

What other people can see

Other people in Sprinter can see your display name, username, profile photo, bio, sports, and follower counts, plus drills you post and comments you write. Your email is not shown on your profile. Follows, likes, and downloads are stored with the account or post they belong to.

Runs, photos, and video

Sprint times are saved on your phone. Finish photos and recorder videos are saved on your phone. The microphone is used only when you record a drill video. If you pick an existing photo or video, Sprinter reads the one you choose from your photo library. A profile photo, and any drill you post, is uploaded so other people can see it.

Location

Sprinter uses your location only when you open the map to measure a distance. It is used to place the map and count metres. Sprinter does not keep a history of where you go, and it does not track you in the background.

Camera and nearby phones

The camera is used to time a finish and to record drills. Body pose detection runs on your phone and is not sent to a server. Two-phone timing uses the local network or Bluetooth to talk to the other phone you connect. The other phone sees your phone's name for that session. Sprinter does not keep a contact list and does not look for nearby phones in the background.

Who else handles the data

Accounts, profiles, and posted drills are stored with Google Firebase — Authentication, Firestore, and Cloud Storage — so they can sync and be shown to other athletes. Sign-in can go through Apple or Google. Purchases, if you buy Sprinter Pro, are handled by Apple. Sprinter does not sell your information, does not show ads, and does not use an analytics product. Google stores this data for Sprinter. Where those servers sit depends on the Firebase project, and that can be outside the EU. Apple and Google handle sign-in under their own privacy terms.

How long it is kept

A cloud profile, posted drill, comment, like, and follow stay until you delete them or delete the account. Times and media that exist only on the phone stay on the phone until you delete those runs or delete the app. A drill another person already downloaded can stay on their phone after you delete the post.

Your rights

You can ask for a copy of the cloud data for your account, ask for a correction, or ask for it to be deleted. You can also ask Sprinter to limit or stop a use that is not required to run the account. Write to naitsab.larc@gmail.com. You can complain to Datatilsynet, the Danish Data Protection Agency. You can use the timer without an account. An account is required for a profile and for posting drills. Sprinter does not make automated decisions about you that have a legal effect.

Deleting your data

You can delete your account in Settings. That deletes the cloud profile, posted drills, and the login. Times and media that exist only on the phone stay on the phone until you delete the app or those runs.

Changes

If this privacy text changes, the new version is shown on this page and in the app with a new date.
