Keep in mind that this step will not permanently delete your data from Meta’s servers. It will remain stored and ready for indexing if you decide to reactivate your account. However, at least your account will not be available to the public, and it won’t appear in search results. This step also allows you to reactivate your account at any time simply by logging in again.
