What is confusing here is that everyone imagines that clearview (and google, and fb, ...) are really storing those pictures. In reallity they just train their ai. There is no trace of that picture on their servers once you delete it. But ai is capable of recognizing you, in case of clearview from picture. In case of google and fb from your picture, browsing habits, contacts, gps coordinates, your friends, semantics of your texts, ... The only difference is that google and fb are not so stupid to advertise this. But capability is there.
