Two important notes:
Only the Owner of the Wootric survey account can delete it. Also if you have a Wootric CXI account, only a Wootric Admin can delete your account.
Once you've deleted your account, your account cannot be restored.
(1) Go to Settings
Once you're logged in to Wootric (and you're the owner of the Account), click on the gear/wheel on the top right of the Wootric dashboard.
(2) Your Account >> Danger Zone
Within Settings, you can reach the Your Account page via the left sidebar under Account Settings. (You may have to scroll to see the Account Settings section).
Scroll down to the 'Danger Zone' and hit "delete account". Make sure you are in the project you want to delete by double-checking that the account name and token are correct.
(3) Confirm with the Account Token
To confirm the deletion process, you'll need to copy/paste the Account Token. It can be found on your current page (Your Account) or within the URL (it will look like NPS-xxxxxxx).
Once you've deleted your account, your account cannot be restored.
