You’re right about the literal “your data isn’t for sale” claim. Still, I have a fun fact: at one point in time, Facebook would let you target an ad to “all men who have any of this list of N emails”, and then accept your list of N emails be N-1 women’s emails, and one man’s emails. Result: direct targeting of a single individual. Or, in this case: direct querying of a single individual’s attributes. I imagine tinder might have closed this hole as well, or maybe it never gave advertisers those exact tools. But these advertising tools can leak a lot of data, and the vendor’s incentive is to leak that data while swearing up and down that it’s safe.
