What happens to your data?

Moonshot AI collects your account details, usage logs, and the content you input to provide and improve their services. Your data is used to train their AI models and may be shared with service providers, affiliates, or legal authorities when necessary.

Does it train on your data?

User content (prompts, audios, images, etc.) is used to train and refine machine learning models and algorithms.

Can you opt out?

No, there is no explicit opt-out for model training, though you can exercise rights to delete your account or restrict processing by contacting support.

Data retention

Retained as long as necessary to provide services, fulfill purposes, or comply with legal obligations; account/input/payment data is kept while the account is active.

Encryption & security

Uses industry-leading encryption algorithms for data at rest and system security protections including regular vulnerability patching and data backups.

Is it safe for work?

Not recommended for sensitive business use as user inputs are explicitly used for model training and the policy does not mention enterprise-grade data isolation or compliance certifications.
