Kimi trains inputs by default without explicit opt-in, shares with service providers and affiliates, commits only to vague retention practices, and relies on passive child protections, but does disclose data categories, offers core deletion/access rights, and uses minimal named security controls.

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

D1.4 , Harmful content licence

Policy grants Kimi "a non-exclusive, unrestricted, perpetual, free license to use and re-license to third parties" , a broad, sublicensable clause reserved without user opt-out.

D5.4 , Vague purpose-to-basis links

Policy lists purposes but links inconsistently to legal bases; many purposes reference only "applicable law" or "legitimate interests" without specific justification, falling short of full transparency.

D2.1–2.5 , Core rights present

Access, deletion (with exceptions), portability, correction, and marketing objection all explicitly named with defined scope; deletion right includes legal/fraud exceptions.

D7.2 , Breach notice lacks timeframe

Policy commits to "promptly inform" of breaches but provides no named timeframe (e.g., 72 hours), rendering the commitment vague.

What the policy is silent or vague on

Not stated: keeping user inputs out of model training
Not stated: a way to opt out of training
Not stated: whether training use differs by plan
Not stated: your ownership of generated outputs
