Before you delete your account permanently be sure thatâ€™s what you want to do, because once you delete it you wonâ€™t be able to retrieve it.
If you are not sure that you will never use that account again then go ahead and permanently delete your account. Once you delete it, youâ€™ll not be able to reactivate your account or retrieve any of the content or or information you have added.
