Qwant claims not to know anything about me, yet I've noticed its results are very much tailored to my location.
I realize this is just data any site can easily see based on my IP, but still it's one of my pet peeves. If I want to see information tailored to my general location, then I'll add the name of the location in the search field. I really hate how search engines try to be so "smart."
I'll give you an example of why it bugs me: The first time I ever looked at Tik Tok, I saw nothing but right-wing MAGA content, certainly based on the political climate where I live. I don't like sites trying to determine my interests based on the fact that I'm in [location].
The only ones that don't seem to tailor results based on my location are SearX instances and Startpage. I have the same misgivings about Startpage, though I use it fairly regularly, and I haven't noticed anything questionable, in spite of the fact that I deeply distrust System1. There's no way they bought into it out of the goodness of their hearts. We may still be in the "bait" stage of a bait-and-switch.
