I used Kagi for a while and liked it but I no longer use it because it is a US company and searching with them requires an account that makes tracing my search queries back to me trivial.
I like it, but that still leaves metadata like the fact that I have an account at all. With the low user numbers of Kagi any privacy guarantee by them is an illusion. Since Kagi is operating out of a country without any privacy laws that could protect me, I will not use their services.
