Does Midjourney train on your data?

Midjourney, Inc. · Image

Yes. Midjourney trains on your inputs on its default tier, with no reliable opt-out. Use an approved business tier for anything sensitive.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: Yes by default; Midjourney's Terms of Service grant it a broad license to reproduce and prepare derivative works of submitted text/image prompts and generated assets, which it uses to train and improve its models by default.
Business-tier training: Yes by default; Paid Pro/Mega users are also subject to model training; Stealth Mode only keeps generations out of the public gallery and Midjourney still retains the license to use them for service improvement.
Training control: Not offered; No reliable training opt-out was confirmed in the sources reviewed for this profile.

Practical risk: All prompts and generated images are public by default and licensed for model training, and Stealth Mode (Pro/Mega only) merely hides outputs from the public gallery without exempting them from training, so confidential work-related content should not be used.

How to make a decision

Check the precise account tier, written contract and intended data before approving Midjourney. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
