How do I delete my user account?
If you'd like to delete your user account, please open profile menu / Edit profile and select Delete your account tab. There you can delete your user account.
Please note that it doesn't delete any workspaces or story maps you are participated in. It just remove your member from these workspaces.
If you are the only subscription administrator in a workspace, you can't delete your account. Please give the ownership to another workspace member by giving him/her subscription administrator role or delete your workspace as describe in this article.
