Zero Data Retention (ZDR) is available only for the Scale plan and only for stateless API calls.
🔑 ZDR is not available for Vibe Work, Chat, libraries, agents, conversations, batch files, or other stateful products that must store data to work. If you use Vibe, you can instead manage your data-training preferences in your privacy settings.
ZDR on Vibe
ZDR is not available for Vibe Work or Chat, regardless of your subscription plan.
This is because we must store your data for user experience purposes (such as accessing your conversation history, showing your previous work, or maintaining application state).
🔑 Conversations are removed from our systems upon manual deletion on your side, or when you delete your account, typically after a short grace period to prevent accidental data loss, and for monitoring and legal retention purposes.
ZDR on Vibe CLI
Vibe CLI runs on your machine and calls stateless APIs. If ZDR is enabled for your Scale organization, Vibe CLI API calls follow the same ZDR rules as the underlying API endpoint.
ZDR on Mistral Studio
When ZDR is enabled, your API inputs and outputs are not retained on our systems beyond what is required to return the response.
🔑 ZDR is available only on the Scale plan (our paid API plan). If you’re on the free plan, upgrade to Scale first.
ZDR applies to the following stateless API endpoints:
/v1/chat/completions/v1/fim/completions/v1/embeddings/v1/moderations,/v1/chat/moderations,/v1/classifications, and/v1/chat/classifications/v1/ocr/v1/audio/speech/v1/audio/transcriptions
🚨 ZDR does not apply to stateful APIs or products, including agents, batch processing files, conversations, libraries, /v1/files, Vibe Work, and Chat. For example, the Files API stores uploaded files and is outside the scope of ZDR.
How to request ZDR
Submit your request directly within our Help Center or by contacting our support team.
🔑 As part of this request, you must provide sufficient detail of your legitimate reasons for requesting Zero Data Retention.
We will review your request and, at our discretion, approve or deny it.
How to check whether ZDR is active
After your ZDR request is approved, it appears in the Privacy settings of the Admin Console.
If it does not appear yet, your request has not been processed.
If your request is rejected, you receive an email.
ZDR, training opt-out, and DPA
ZDR and training opt-out are separate controls:
ZDR controls whether supported API inputs and outputs are retained after processing.
Training opt-out controls whether eligible data may be used to improve Mistral’s models.
