Mistral gives Le Chat users named in-account controls to export, delete and object to training, but consumer chats are used for model training unless you opt out, the content licence Mistral takes can be passed to its subcontractors, and the policy says nothing about security controls or breach notice.

What Mistral Le Chat's privacy policy and terms of service say about your data

Training is opt-out, not opt-in

Free, Vibe Pro and Vibe Student conversations are used to train Mistral's models unless the user turns training off, and flagged or reported content can be used regardless.

Strong self-service controls

Account settings carry named controls to export data, delete the account, and object to input and output being used for training, with a DPO contact form as a backup route.

Sublicensable content licence

Users keep ownership of inputs and outputs, but Mistral takes a worldwide licence that it may sublicense to its delegates and subcontractors.

Security disclosure is missing

The policy names no encryption, access-control or other technical safeguard, and sets out no breach-notification commitment or timeframe.

What the policy is silent or vague on

Not stated: a standard for government and law-enforcement access
Not stated: its security safeguards
Not stated: breach notification
Only partial: keeping user inputs out of model training
