So make a new account every once in a while if you are that paranoid. The whole value proposition of kagi is that it moves you from being the product(eyeballs for ads) to the customer of a product(search results) This flips the incentive of the search provider from abusing you to serving you. Hard to say if it actually will work. But I applaud kagi for trying.

And it is not like you marry kagi and once you sign up you can never use another search engine again.
