Midjourney — privacy & data policy

Provider: Midjourney. PromptPrivacy score: 38/100. Last verified October 18, 2026.

What happens to your data?

Midjourney collects account details, prompts, uploaded media, and usage metrics to operate, secure, and improve its image generation services. This information may be shared with third-party service providers, analytics and advertising partners, and legal authorities when required. Users can manage privacy settings or delete their account and data via self-service account tools.

Does it train on your data?

Midjourney states that its policy applies to personal data collected through the process of training its machine learning algorithms and uses personal data to maintain and improve its services. The policy does not outline a specific method for users to opt out of having their prompts or inputs used in AI model training.

Can you opt out?

Users can opt out of marketing communications and non-essential advertising cookies via account settings, and California residents can opt out of data sharing. However, the policy does not provide a specific option to opt out of machine learning model training or general service improvement while using the service.

Data retention

Midjourney retains personal data only for as long as necessary to fulfill the purposes described in the policy, comply with legal obligations, resolve disputes, and enforce agreements. Usage data is typically held for a shorter period, unless required for service security, functional improvements, or legal compliance.

Encryption & security

The policy does not explicitly mention encryption in transit (such as TLS), encryption at rest, or third-party security certifications (such as SOC 2 or ISO 27001). It only states that Midjourney strives to use commercially acceptable means to protect personal data while noting that no transmission or electronic storage method is completely secure.

Is it safe for work?

Caution is warranted for confidential or proprietary business use. Midjourney collects prompts, uploads, and sensory content to train machine learning models and improve services, without detailing explicit enterprise-level data segregation, technical encryption standards, or training opt-outs.
