We've just released documentation about our model providers, https://help.kagi.com/kagi/ai/llms-privacy.html, to clarify how each handles data.
I know this doesn't address all your points, but as noted in #5780, we will be releasing a new privacy policy soon, which should address all your questions.
I'll merge both threads to streamline communication once the latest privacy policy version goes live
Thanks! I think we need to probably look at Mullvad and AdGuard VPN to provide a solid but easy to follow policy as there are so many products from Kagi now!
What is retained irrespective of interaction, what is retained when interacting are really nicely written for AdGuard VPN. Mullvad also does nice breakdown of exactly what things look like on their server plus retention times for things that are collected.
Mullvad is audited but Kagi like AdGuard VPN is unaudited. AdGuard has reputation benefit but Kagi has to win those users right?
Luis Hi, do you have a rough estimate of when the new version of the privacy policy will be released?
Refract9305 hopefully this week, but no later than next week
Luis Ahem... 
Luis Hi, do you any updates on the situation with the privacy policy?
Refract9305 This one is planned but not sure what the ETA might be..
I should have learned by now not to discuss deadlines... :/
The new privacy policy is finalised and will be released soon. We're planning to publish it alongside a few major updates, including Privacy Pass, but the latter needs a few more days of polishing before its official release.
Luis Oh no.. Privacy pass is delayed, again? 
It must be a trickier implementation than assumed. The paper made it look so easy. But to be fair, their own extension had 2 star ratings on Firefox and Chrome which shows how hard it might be to make it work right.
