Cursor sends code context to Anthropic, OpenAI, and other model providers via Cursor’s servers; Privacy Mode (off by default on Free/Pro) is required to opt out of training. Cursor Business adds SSO, central billing, and a server-side privacy guarantee. Be aware: even with Privacy Mode on, Cursor caches certain context server-side for performance.
