After you've confirmed that you want to deactivate your account, you'll be taken to a page that summarizes your account information. This includes things like your phone number, username, and any groups or channels you're a part of. Take a look over this information to make sure everything is correct.
Finally, you'll be asked to confirm that you want to delete your account permanently. This is the last step, so make sure you're really sure about deleting your account. Once you've confirmed, your account will be deleted and you won't be able to recover it.
