Lumen Trust Notes
Windsurf
Agent and chat traffic generally goes to Windsurf/cloud model providers unless enterprise deployment options say otherwise—Privacy Low for typical Pro use. Free tier plus $20 Pro supports Medium parity. Purpose is High for accelerating real software work. Provenance Low due to closed product and third-party frontier models. Review privacy/zero-retention options before connecting proprietary repos.
Cursor
Cursor offers a Privacy Mode that disables code retention and training on your data, elevating its privacy posture above most cloud coding tools to Medium. The product is purpose-built to maximise developer productivity with transparent data-handling options, reflecting a genuine user-first mission. A strong choice for professional developers, especially with Privacy Mode enabled for any proprietary or client code.
