"Midjourney presents a high-risk privacy profile (score: 62/100) comparable to mainstream tech services with ad-supported models. The service collects extensive personal data including user prompts, uploaded images, and behavioral inferences explicitly for AI/ML training without itemized opt-in consent. Critical concerns include indefinite data retention for legal compliance, broad third-party sharing with advertising partners, and tracking via third-party cookies—with opt-out required rather than opt-in as default outside GDPR regions."

Users can request deletion and account removal, but no guarantee that all associated data (especially data used for ML training) is permanently deleted from all systems and backups.
Midjourney uses third-party tracking cookies and pixels for behavioral advertising and personalization. Advertising partners receive personal data to deliver targeted ads based on inferences.
Data retention period is vague with 'as long as necessary' language. Policy retains data indefinitely for security, legal compliance, and dispute resolution without clear deletion timelines.
