I appreciate moving away from cloud for personal health data like this.

Can you clarify why the ideal world you hint at would have the device sending any data to you?

Devices sending data that is anonymized, encrypted, and signed by the device is a must-have for some medical studies.

For example, imagine a medical study that looks at heart rate variability versus an intervention. The data analysts won't need to know each patient's name or email address, but will need to know each patient's heart rate variability when you're having the intervention. The study may span many physical locations, such as at multiple medical providers across a country.

Ditto on this! I've avoided fitness trackers so far because I don't want any cloud aka my data on someone else's computer

for regular users, since the device itself doesn't have any interface, we need to send at least some data so they can see it somewhere. the natural place is the phone, but not all of our professional clients liked viewing long ECG recordings or detailed metrics on a small screen, so we built cloud access mostly for convenience .

(to be clear - if a developer wants, they don't need to send anything to us)
