Claude Code Local Storage Context History on Your Device: Deleted After 30 Days (code.claude.com)

Anthropic has updated its data retention policies for its Claude Code service, emphasizing user privacy and control. For consumer users on Free, Pro, and Max plans, data retention now lasts 30 days unless users opt-in to sharing their data for model improvement, in which case data may be retained for up to five years. Commercial users, including those on Team and Enterprise plans, will continue with existing policies, where any data used for training must be explicitly consented to. Notably, users can adjust their privacy settings at any time through the Claude AI interface. This update is significant for the AI/ML community as it reinforces Anthropic's commitment to user privacy while enabling data-driven improvements to their models. The local storage feature, which retains session transcripts in plaintext for 30 days, enhances usability by allowing session resumption without compromising security – data is encrypted and protected when sent to or stored by Anthropic. The move aligns with increasing demands for transparency and user control in AI data usage, marking a step forward in responsible AI practices.
