This is a personal, non-commercial tool provided as-is and without warranty, built to sync one person's own activities between two services they already use. By authorizing it, you agree that it may read your Decathlon Coach activities and create matching activities on your Strava account on your behalf.
You can revoke this access at any time from your Decathlon or Strava account's connected-apps settings — doing so stops the sync immediately. Questions? Email info@te-run.com.
