One of Kagi's core principles seems to be that they don't try to guess what you want. Their "Personalized Results" settings just ask you to tell them which domains you like and which you're tired of seeing. It makes sense that they'd ask you for your locale rather than guessing it from your IP or asking for location access.

As someone who's sick and tired of the way Google tries and fails to guess what I want—to the point of now ignoring me when I try to tell it what I want with search operators—I appreciate this philosophy!
