I think the idea here is that it literally can't be traced to the user – at no point is there anything passed that would allow Kagi to make the association between the user and the query.
I’d love to assume this will never happen, I’m just concerned that even if it did I’d never find out - Because unfortunately the more popular this service gets for bad actors, the more of a target it becomes for the government with identification of users.
I guess as a search engine, we could assume the government may leave them well alone and still just focus on content creators.
Cryptography is a literal godsend for people living under oppressive regimes.
