Lunas is a personal health record and medical AI workspace. People upload lab reports, imaging, genetic data, and clinical documents, and talk to Stethos about them. That is among the most sensitive data a person has, and the point of this page is to describe how it is handled without rounding anything up.
Every control listed here is in place today. Where our compliance posture is incomplete, this page says so rather than describing an intention. Claims about security are worth exactly as much as their weakest sentence.
