You can delete your Community account and everything you shared at any time.
This permanently removes your profile, hosted rides, RSVPs, posts, comments, messages, likes, reports and blocks, and your sign-in. It cannot be undone.
Your rides, bikes, contacts and Medical ID are stored only on your phone and are not part of the account. Delete the app (or use Settings, Data and about, Erase all data) to remove them.
Use the contact option in the app, or reinstall the app, sign in and delete your account.
