That's not really possible. Proof: Say Alice is your client, and her ad targets gay people (even though the ad or the advertised product itself is not necessarily related to being gay). Then using your data about sexual preference, you serve the ads only to gay people. Only gay people will see the ad, and thus only gay people will reach Alice's website. Hence Alice got the data out. QED.
