You can never know what google knows about you. You can see the information you gave google. A list of GPS coordinates or some search terms for example, but you aren't allowed to know what Google knows about you because of those things. Who you are sleeping with and how often, which medical conditions you have, what your religious and political views are, what you are sexually attracted to. Google knows all of those things about you but you'll never find those kinds of records using any interface google offers you and you have no power to delete them.
