Someone mentioned algorithms earlier. My son works in Music and when a song/album is released or they advertise it on Social Media, they just input the target age range/gender/interest etc. from a computer generated interest list and it will auto-send an advert to the targetted audience. Can you imagine going though lists of people by hand? Nobody does that anymore. So the answer is, yes you could loosely say your details are available, but most 'mail' is just automated and nobody really reads your data - it being just a quick way to reach the targets.
Best tell your son about data mining. They're not doing it by hand 
Adverts for running shoes are targeted at people with FitBits who have done a lot of running. "They" forecast when you might want to buy new running shoes.
They really do read your data. But "they" are a data mining system, not somebody with a pencil and paper....
