TL;DR
PostHog will train ML models on customer session replay and behavioral data starting June 29, with opt-out available for EU users and those with data restrictions.
Key Points
- Training launches June 29, 2026 with default opt-in for US cloud users, default opt-out for EU users
- Models will power new features: automated session replay analysis, synthetic user testing, and conversion optimization suggestions
- All data anonymized before training; models trained in-house without sharing data to third-party providers
- Users can opt out anytime via org settings; opted-out users won't access new AI-powered features
Why It Matters
This represents a significant shift in how product analytics platforms use customer data to improve their tools. For developers, it raises important questions about data governance, consent mechanisms, and the tradeoff between feature capability and data privacy—especially relevant as ML-powered product features become standard industry practice.
