Your original comment was about _third parties_ getting access to ads, and that was what I was claiming doesn't apply to basically any large ad network. It sounds like what you're saying now is that all the handling of user data happens fully on device and the ad network itself doesn't have access to demographic data, which is definitely not true for Google/FB/etc. That's interesting if true, but I'm pretty sure that's very, very wrong. Do you have any source for this? I tried Googling it and was unable to find anything saying that, and I would be pretty surprised if that's how it works (especially pre-downloading inventory), given my passing familiarity with how ad networks work. Especially since their privacy page (which talks about iAd)[1], makes no mention of something which would be a drastically different way of operating an ad network (and thus excellent for marketing onself as the privacy-conscious alternative).
