Analytics chart with a privacy-shield breach icon

Analytics provider Mixpanel was breached in November 2025. Leaked datasets affected OpenAI, Pornhub, and other Mixpanel customers whose analytics events sometimes contained embedded user identifiers. The privacy implications are significant: analytics platforms often see far more user data than the host service intends to expose.
