You can delete your account and all your data by using one of two ways. Once deleted, the account username is locked so no one else can use the name.
- From the mobile app account profile page. Go down to the bottom and select the red "Delete" option.
- From zello.com. Log in at https://zello.com/user/home using the account that you would like to delete,. Activate the "Account" tab and click on a link in the "Remove account" section at the bottom of the screen.
