Mistral AI uses your data including your conversations, feedback, and identity data to conduct research and improve its products, relying on 'legitimate interest' rather than your consent as the legal justification.

The clause operationalizes a specific legal mechanism under data protection frameworks that permits data processing for product improvement and feature development without requiring explicit user consent, contingent on the processing serving the entity's legitimate interests rather than user interests alone.
The updated policy now explicitly includes data accessed through third-party services and integrations users connect to Mistral AI Products as 'Input' data subject to collection and use. The policy removed its prior statement that Input and Output data are not used to train AI models when using Le Chat Enterprise or paid versions of Mistral APIs. This creates operational ambiguity: users of paid services and Enterprise customers no longer have a documented commitment that their data will be excluded from model training, though the privacy policy does not affirmatively state that model training now occurs. The policy also changed language describing product improvement from 'aggregated and anonymous statistics' to 'aggregated or anonymous datasets or statistics,' broadening the stated scope of what can be collected for improvement purposes.
