Medicyn: Your complete medical history privately on your device

@igorgurovich Hi Igor, thanks for your comments. Good luck with your app, and I can’t wait to see what you create! Each record has a “Share as PDF” option that generates a neatly formatted PDF and opens the iOS Share Sheet — so you can AirDrop, message, email or print. Scanned documents can also be shared in their original format.

Two things help here: (1) Madison supports multiple family profiles. on the same device (for example, a caregiver manages both his and a parent’s records in one app), and (2) you can export a full encrypted backup and share/import it to another family member’s device if needed. It’s manual rather than real-time, but it prevents your family’s health data from ever touching a third-party server.

Right now, everything is local first and resides on the same device — there’s no cloud sync or live shared access between devices (by design, for privacy). Shared read-only access across all devices is something I’m considering for the future, but it’s a trade-off against the zero-server privacy model I’ve built the app around.
