How does Kagi (claim that they) enforce privacy rights on the major LLM providers? Have they negotiated a special contract?
I'm looking at
> "When you use the Assistant by Kagi, your data is never used to train AI models (not by us or by the LLM providers), and no account information is shared with the LLM providers. By default, threads are deleted after 24 hours of inactivity. This behavior can be adjusted in the settings."

And trying to reconcile those claims with the instant thread. Anthropic is listed as one of their back-end providers. Is that data retained for five years on Anthropic's end, or 24 hours? Is that data used for training Anthropic models, or has Anthropic agreed in writing not to, for Kagi clients?
