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.
