Two ways to do this. The first one is immediate.
Deletion is permanent and cannot be undone. It removes your profile, your photos, your matches and messages, your check-in history, your waves, your plans and the files behind all of it.
Open Wingman and go to More › Settings › Delete Account. It happens immediately, while you watch, and nothing is queued for later.
Deleted the app already? Reinstall it and sign in with the same phone number - your account is still there until you delete it - then use the same screen.
Lost the phone number, or cannot sign in? Ask us here and we will delete it for you. We cannot delete an account from a phone number typed into a web page alone, because anybody could type anybody else's, so this one is a request rather than a button.
Digits and the country code. Nothing is sent to this number.
In the app: everything below goes at once, and the account is gone before the screen closes.
By request: we complete it within 30 days, and in practice within a few days. You will not get a confirmation message from us, because a deleted account has no phone number to write to.
Two things are kept, and only these: a record that a phone number was banned, if yours was (so a ban cannot be undone by deleting the account), and aggregate counts that identify nobody. Backups roll off on their own within 30 days.
