Anthropic Updates Claude's Privacy Policy: User Data for Model Improvement
2025-08-29
Anthropic has updated Claude's Consumer Terms and Privacy Policy, giving users the option to allow their data to be used to improve Claude's capabilities and enhance safety features. Opting in allows your data to be used for model training, improving Claude's coding, analysis, and reasoning skills, but extends data retention to five years. Opting out maintains the existing 30-day retention period. This update applies to Claude Free, Pro, and Max plans, but excludes services under commercial terms. Users can adjust their preferences at any time in their settings.
