Default opt-in training for Hobby/free tier users (affects developers who may share proprietary code in prompts). Stealth/beta model users have zero data protection guarantees — third parties may train on their inputs. Published v0 projects (chats, templates, code) are public and can be copied. Agentic risk: v0 generates deployable code that integrates with APIs, databases, and live infrastructure.
Enterprise plan provides full no-training guarantee. Output IP fully assigned to user. SOC 2 Type II + ISO 27001 certifications. Clear opt-out mechanism for eligible plan tiers. Vercel is a well-established, transparent company. v0 Enterprise Addendum provides additional protections.
