Scroll to the bottom of the page and, under Settings and preferences, click Edit profile. Remove your information from the Personal Information and Contact Details sections. Some fields are mandatory - replace the info in these with random characters, because you won’t be able to save it if the fields are empty. Click Save.
Note: You should leave your email address in your profile so that we can verify your account when closing. After we have closed the account, we will remove your email address.
