AI features process this sensitive content through LLM subprocessors. CLOUD Act jurisdiction. Agentic API access allows automated reading and writing of workspace content. Non-enterprise users have weaker LLM data protections.

Use Enterprise plan for ZDR with LLM providers and stronger compliance controls. Execute DPA for GDPR. Review Notion AI subprocessor list. Limit API integrations to least-privilege access. Do not store regulated data (HIPAA, PCI) without specific compliance agreements. Notion's explicit no-training policy is a strong positive control.
