How secure is Claude Code when processing proprietary code?
The tool operates locally on your machine and communicates directly with Anthropic’s API without requiring backend servers or remote code indexing, which means your code isn’t stored on intermediate systems. Anthropic has implemented policies stating they will not train generative models using feedback from Claude Code, and they maintain limited retention periods for sensitive information, storing user feedback transcripts for only 30 days with restricted access to user session data.
