To access your Facebook user data deletion settings, navigate to your account’s “Settings & Privacy” section, then go to “Settings” and find “Apps and Websites” where you can manage which apps have access to your data and remove them if needed to delete associated information; there is no single dedicated “data deletion URL” but you access the relevant settings through this path.
