ChallengeUS is a running and triathlon coaching app by Shatoot GmbH, Zug, Switzerland. This page explains how to delete your account and your data, in the app or without it, what we delete and what remains.
Last updated: 2026-10-22
In the app: the fastest way
On iPhone and Android: More → Delete account. In the web app (app.challengeus.com): Profile → Delete account.
After two confirmations we delete your account and data at once and you are signed out. This cannot be undone.
Without the app: by email
If you no longer have the app or cannot sign in, write to info@challengeus.com from the email address you use for ChallengeUS and ask us to delete your account.
If you sign in with Strava only and your account has no email address, include the name on your Strava profile in your message.
We delete your account and data within 30 days of your request.
What we delete
We permanently delete your profile, plan, races, imported activities and nights, the conversation with the coach, your messages and name in Groups, your reports and ideas, your email address on the beta waiting list and the links to Strava and Garmin. We revoke our access to Strava and delete your sign-in account.
The activities you recorded stay in your Strava and Garmin accounts: to delete them there, follow the instructions of those services.
What remains and for how long
Backups are erased within 90 days.
Server logs needed for security (IP address, date and time) are erased after 30 days.
Reports you made on other people's messages are kept for moderation, without any reference to you.
Only counts that do not identify you remain, such as how many athletes used the app on a day or what the coach cost.
Pioneers
If you are one of the pioneers, deleting your account means you lose this status and cannot get it back. The same applies to a place among the first 200 athletes that is not yet confirmed.
Keep the account, remove some data
To remove only some data, disconnect Garmin and Strava or clear your data under More. To access, correct or export your data, write to info@challengeus.com.
