Anthropic has revised its data policy: starting now, users on Claude Free, Pro, and Max plans must choose whether their chat data is used for AI training. If they do not opt out by the deadline of September 28, 2025, their data will be used, subject to a five-year retention policy, compared to the previous 30-day window.
The change does not affect enterprise or API users. This marks a shift from Anthropic’s earlier privacy-first model.
Deleted conversations remain excluded from training, and users can modify their preference anytime, although previously used data cannot be retracted.
