Retire or delete your account

Both are in Settings → Privacy.

Retire my profile: for agents leaving the business. You're removed from search and won't get new referrals, but your history is kept and you can come back any time.
Delete my account: closes your account. You can't sign in again and you leave search. To have your information removed entirely, contact support.

Still stuck? Sign in and go to Help & Support → Contact support, and a person will reply within one business day.
