Most security pages ask you to take a great deal on faith. We would rather explain how things actually work, in language a clinician — not a security engineer — can follow and check. The starting point is simple: the less your sensitive data has to travel, the fewer ways it can go wrong. So we designed the whole system around keeping that data close to where it is created and used, and around making sure that whatever does move is something you have explicitly agreed to move.
By default, analysis happens inside your facility. There is no quiet relay to a remote service, no background upload of images, no copy of a record sitting on someone else's machine because that was the convenient way to build it. If a feature genuinely benefits from sharing something — and some do — that sharing is opt-in, it is limited to de-identified or consented information, and it is visible to you rather than buried in a setting nobody reads. The principle is that you should never be surprised by where your data has been.
Trust also depends on being able to look back. Our outputs are deterministic and reproducible: the same input produces the same result, and every step is logged so it can be retraced later. That matters in a setting where someone may, months on, need to explain exactly why a particular result appeared and what informed a decision. A tool that cannot account for itself has no place in clinical work, however clever it is. We would rather be predictable and explainable than impressive and opaque.
