Is it possible and cost-covering to create an ad-sponsored service that discloses what ad networks collect about users - i.e. age, location, preferences, interests, pregnancy, illnesses etc?

Because let’s be honest - all of us know that a lot of data points are being collected about us, countless articles have been written about the insanity of cookie and user-data monetization networks - still it appears to be a privilege to few to tap into that data trove.

I personally haven’t seen an effort to try and make this transparent. Efforts like this page are commendable and informative, much like amiunique or other services - still they lack the tangible information that sharing this information with “the world” reveals about an affected individual.

Why hasn’t this been done yet? Why is this seemingly not trivial?

I'm unaware of how other platforms work, but for Google you can just see what buckets have been associated with your account:

I'm not sure how that would work from an ad-buying perspective, from what I understand you essentially choose which buckets you'd like to show ads to? Like I don't think ad-buyers get the whole dossier for the person they're showing ads to, the platform just decides "from what you've told us, this person seems likely to like your ads"

You mean something like https://consumer.risk.lexisnexis.com/request?

Or more like "on ad network X you match for keywords A, B, F, G"?
