Kimi — privacy & data policy

Provider: Moonshot AI. PromptPrivacy score: 39/100. Last verified November 01, 2026.

What happens to your data?

When you use Kimi, your account information, prompts, uploaded files, and device technical data are collected and stored on servers in Singapore. Moonshot AI uses your inputs and interactions to operate the service and to train and refine its machine learning models. Your data may also be shared with service providers for infrastructure support and with corporate affiliates.

Does it train on your data?

Trains on your content by default. Moonshot AI uses prompts, audios, images, videos, files, and other inputs and outputs to train, refine, and optimize its machine learning models and algorithms.

Can you opt out?

Not specified. While the policy outlines that user content is used to train and optimize machine learning models, it does not specify any mechanism or setting to opt out of model training.

Data retention

Account, user input, and payment details are stored as long as your account remains active. Information is also retained as necessary to fulfill business purposes, improve services, comply with legal requirements, or resolve disputes.

Encryption & security

Moonshot AI implements industry-leading encryption algorithms along with system security vulnerability patching, restricted employee access controls, distributed offsite backups, and real-time monitoring for abnormal access.

Is it safe for work?

Use with caution. Kimi trains its AI models on user prompts and uploaded files by default without an explicit opt-out mechanism, and the policy lacks enterprise-specific protections or SOC 2/ISO certifications, making it unsuitable for confidential or proprietary business information.
