August 28, 2025
Anthropic has updated its consumer terms, allowing users to opt in or out of data sharing for AI model training. This change affects Claude Free, Pro, and Max users, with a new data retention period of five years for those who opt in.

Anthropic has announced updates to its consumer terms, requiring users of its Claude Free, Pro, and Max plans to decide by September 28, 2025, whether they want their data used for AI model training. In a company announcement, Anthropic detailed that users who opt in will have their data retained for five years, a significant change from the previous 30-day retention policy.

The new policy does not affect business customers using Claude Gov, Claude for Work, Claude for Education, or API access. Users can adjust their data sharing preferences at any time, and new users will make their choice during the signup process. Existing users will encounter a pop-up notification to make their decision.

Anthropic emphasizes that participating users will contribute to improving model safety and capabilities, such as coding and reasoning skills. The company assures that data will not be sold to third parties and will be protected through various privacy measures.
