Used for training by defaultStated

Mistral trains in accordance with its privacy policy unless the customer is or has opted out. Feedback is excluded from the opt out, as are laboratory and preview models.Mistral AI data processing addendum, primary source, 27 July 2026.

Retention periodStated

Thirty rolling days for abuse monitoring on standard calls unless zero data retention is on, and open ended for fine tuning data and the agents API.Mistral AI privacy policy, primary source, 3 September 2026.

Deletion on requestStated

Fine tuning data is kept until the customer deletes it from the platform or terminates the account, so deletion is an action rather than a schedule.Mistral AI privacy policy, primary source, 3 September 2026.

Storage region and residencyStated

A French processor with European infrastructure preference, and the current standard contractual clauses attached to every contract involving processing outside the European Union.Mistral AI privacy policy, primary source, 3 September 2026.

Subprocessor list publishedStated

Defined in the addendum with a general authorisation, and published on the trust centre rather than inside the contract.Mistral AI data processing addendum, primary source, 27 July 2026.

Human review of contentSilent

Only automated moderation is described. The addendum names automated moderation including abuse monitoring on the APIs, and no human review clause appears.Mistral AI data processing addendum, primary source, 27 July 2026.

Opt out availableStated

Two mechanisms. An account level training opt out, and zero data retention, which is gated: the customer must give sufficient detail of a legitimate reason and Mistral approves or denies it.Mistral AI help centre, activating zero data retention, primary source, 12 August 2026.

DPA availableStated

Yes. A full data processing addendum with the European standard contractual clauses, supplementing the commercial agreement and referencing the trust centre.Mistral AI data processing addendum, primary source, 27 July 2026.

Persistent memory across sessionsStated

Statefulness on the platform is the agents API, where inputs and outputs are kept until the account is terminated. The knowledge base feature belongs to the consumer assistant.Mistral AI privacy policy, primary source, 3 September 2026.

Last change to the termsStated

The privacy policy prints Effective 3 September 2026, the commercial terms 5 August 2026, the addendum 27 July 2026 and the zero retention help article 12 August 2026.Mistral AI privacy policy, primary source, 3 September 2026.

1. 30 days

   Rolling abuse monitoring retention for standard API calls

   Mistral AI privacy policy, primary source, as of 3 September 2026.

Opt outs on this platform do not travel. The consumer toggle, the platform toggle and zero data retention are three separate decisions, and none of them reaches the laboratory and preview models, where the terms simply say not to use them if you do not want training. Any workplace rule here has to name the surface, and any customer answer about zero data retention has to say it was approved, since it is granted on request rather than switched on.
