How do we know these privacy claims are true? What if Kagi was Chinese or Russian, would you still trust it and why? And how do we know Kagi doesn't end up the same way as DDG?

Being a paid service means Kagi's incentives are very different. Instead of selling your data or profiting from feeding into ad-tech food chain, we are interested in selling you a subscription. This changes everything as the number one thing in Kagi's universe becomes what the users want, different to DDG, Google and other ad-supported search engines.

Sadly I can not think of a way to verify them (let me know if you have one). But most plainly, we have no incentive or reason to do otherwise. Note that the only private information Kagi asks of the user is an email address, need to create an account, and those concerned can use whatever email they want.
