We have a double defense against reading or editing of personal data. First, we ensure that all "protected" views are only visible to logged-in users. Only logged-in users have buttons leading to the private parts of the site. As a second step, protecting against guessing of URL, before serving data from the database, we check explicitly that the data is owned by the user in question, redirecting unauthorized requests to a "Permission Denied" page.

Team Functionality

On, users with the paid "Coach" plan can establish teams and invite other users to become part of the team. The purpose of a team is to share workout and training plan data between the coach and the team members. In terms of sharing behavior, there are two types of teams:

  • "All Members" - This is the default team type. All members can see workouts of all other members, except those workouts that the members have marked as "private".
  • "Coach Only" - With this setting, each individual team member is sharing his workout data only with the team manager. Other members cannot see his workouts.
The sharing behavior is chosen by the team member when he establishes the team and can be changed during the existence of the team.

By accepting an "invitation" to become a member of a team, or by requesting to become part of a team, you agree to automatically share all your workout data (including workouts done prior to becoming a member of the team) to the team manager (coach) and, depending to the team policy, to other members of the team. When you leave a team, all your workout data will immediately become invisible to those who had access to it during your team membership, including workouts that cover the period of time when you were member of the team. As a member of a team, you grant the team manager permission to edit workout data on your behalf, including the creation of charts and cross workout analysis. You also grant the team manager permission to edit your heart rate and power settings, as well as functional threshold information and the account information accessible on your settings page under the header "Account Information". The team manager is not able to access or change your passwords, team memberships, favorite charts, export settings, workflow layout, or secret tokens. Also, the team manager is not able to download all your data, not can he deactivate or delete your account.

Each team member is bound by this privacy policy and the GDPR regulation of the European Union regarding the personal data of other team members that he has access to. By accepting an invitation to a team, the new member agrees to limit the use of these data strictly to the allowed use according to this privacy policy and the GDPR.

Team managers can access requests of users to be added to one of their teams. By accepting the invitation, the manager accepts the responsibilities and duties associated with access to personal data of the new team member. He is bound by this privacy policy and the GDPR regulation of the European Union regarding the personal data that he has access to.

In case that a team manager wants to change the sharing behavior of one of his teams from "Coach Only" to "All Members", he has to inform all impacted team members in due time. He shall give team members a minimum of three days to decide whether they agree with the new sharing policy, and collect the consent of the team members with the new sharing policy. The team manager must remove team members who did not give their active consent to the new policy from his team. If a team member has not responded within 7 days of being notified, the team manager will understand this as "no consent" and remove the team member.

When notified of a change in team sharing behavior by the team manager, the team member has to decide whether he agrees. In case of disagreement, he shall revoke his team membership within less than 7 days of being notified.
