adam.shane.coburn@gmail.comHow do I connect my health data?
Open Settings → Connect Apple Health (iPhone) or Connect Health Connect (Android) and approve the data types you want the app to read. Until you connect, the app shows a clearly labelled sample preview.
Why don’t I see medications, labs or conditions?
On iPhone these come from Apple Health Records, which requires a real device signed into a supported health system in the Health app (they never appear in the simulator). Google Health Connect does not expose clinical records, so on Android add them by hand with the + Med, + Condition and Add result buttons.
Some metrics are missing on Android.
Health Connect doesn’t provide VO₂ max, running dynamics or heart-rate recovery. You can enter those manually.
Where do the “Normal Fontan” and “Super Fontan” numbers come from?
They are general, configurable defaults — a typical adult Fontan value and an aspirational target. They are not personal targets; review them with your congenital-cardiology team.
How do I cancel or restore Premium?
Premium is managed by your App Store / Google Play account — cancel there any time. Use Restore purchases on the Premium screen after reinstalling or switching devices.
Does my health data leave my phone?
Not by default. The only exception is Premium AI Prognosis, which sends a metrics summary (not your full record) to generate your write-up. Details are in the Privacy Policy.
