Mistral AI uses the messages you type and the AI's responses from the free version of Le Chat to train its AI models, unless you actively opt out in your account settings. Paid enterprise and API customers are automatically excluded from this.
Your chat prompts and AI responses on the free tier are used to train Mistral AI's commercial language models, meaning personal information you share in conversations could influence future AI outputs unless you opt out via account settings.

(1) REGULATORY FRAMEWORK: This provision implicates GDPR Art. 6(1)(f) (legitimate interests) as the stated lawful basis, which requires a documented Legitimate Interest Assessment balancing Mistral AI's training interests against user privacy rights. GDPR Art. 13(2)(b) requires transparent disclosure of this processing at point of collection. The EU AI Act (Regulation 2024/1689) imposes transparency and data governance obligations on providers of general-purpose AI models trained on such data. French CNIL is primary enforcement authority; Article 56 GDPR one-stop-shop mechanism applies for cross-border EU enforcement. (2)
