Anthropic's August 28, 2025 update to the Consumer Terms and Privacy Policy asks Free, Pro and Max users to choose whether their chats and coding sessions are used to train new models. If allowed, retention extends to five years; otherwise the 'existing 30-day data retention period' continues. It applies only to new or resumed chats. Team, Enterprise and API use are not covered. The deadline for existing users was first September 28, 2025 and later October 8, 2025.
