OK.
This is kind of scary.
I uploaded my profile pic to
https://theyseeyourphotos.com/
This is a site, setup by a former Google employee to show you, how Google would interpret a picture of you.
The result is not 100 % accurate (e.g. that I could be targeted with alcohol ads, but I hardly ever drink), but found the exact location and enough to be worried if they analysed a set of, say, a dozen photos.
@mina I uploaded the profile pic I use on here. It got my age right and correctly described my clothing and spotted that the photo was taken in Wales. But the only hobby it got right was reading and it did think I might be a compulsive worrier, which is true. But other than that, it was all pretty generic, based on my age or actually incorrect. None of the things it suggested could be marketed to me are things I would buy.
Basically I think it's about as accurate as a magazine horoscope.
