Kimi discloses model training on user content with a contact-based opt-out and names concrete in-product paths for access, correction and chat deletion, but its terms grant a perpetual re-licensable content licence and the policy is silent on deletion timelines, ad-sharing opt-outs and government-access standards.

What Kimi's privacy policy and terms of service say about your data

Perpetual content licence

The Terms of Service grant Moonshot and its affiliates a non-exclusive, unrestricted, perpetual, free licence to use and re-license user content to third parties, which is an explicit reserved harm even though the same terms say copyright in inputs and generated content belongs to the user.

Training opt-out exists but is manual

Kimi states it uses input and output content to optimize its models after de-identification, and offers to stop only if the user contacts customer service and passes identity verification, so there is no self-serve toggle.

Concrete in-product rights paths

Access, correction, copy, chat deletion and account deletion each name a specific screen such as [Settings], [Chat History], [Delete Chat] and [Account Security], which is stronger than the generic rights language most policies offer.

Three disclosures missing from the text

The documents give no deletion timeline after account closure, no opt-out for sharing with advertising partners and no government-access standard. All three are absent rather than merely vague.

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
Not stated: a deletion timeline after closure or request
Not stated: shorter retention for AI conversation logs
