Vendor data-handling terms

Training on your data (default tier)
Inputs and outputs used for model training unless the user opts out in account settings

The policy lists training Mistral's language models as a purpose for processing Input and Output, subject to an opt-out available in the account's user preferences.

“Your Input and Output, subject to your opt-out. / You can opt-out of this processing at any time through your user preferences on your Mistral AI Account.”

Training on your data (business tiers)
API inputs and outputs kept 30 rolling days for abuse monitoring; zero data retention available

The API retention clause below is the closest statement on business use; the policy does not separately state that API data is excluded from training.

“Except for specific APIs, we keep your Input and Output for the period necessary to generate the Output and then for thirty (30) rolling days to monitor abuse (unless zero data retention is activated).”

Assessment

Consumer chat, opt-out not set: mediumConsumer chat with training opt-out: lowAPI: low

Reasoning: Training on inputs is on unless the user opts out, which is the same exposure profile as other consumer assistants; the difference is an EU controller under GDPR, EU-first hosting, and a 30-day API retention window with zero data retention on request. For an EU deployer the open item is the opt-out state on personal accounts, not the location of the data.

Flags: GDPR Art. 21 objection mechanism relied on for training opt-out (consumer) · Assessed 2026-09-15. The assessment is Unseen's; the terms above are the vendor's.
