A controller must delete any or all personal data provided by or obtained about the consumer on an authenticated request. For data obtained from a source other than the consumer, it complies either by deleting the data while keeping a record of the request and the minimum data needed to keep it deleted (used for nothing else), or by opting the consumer out of all non-exempt processing of that data.
