If your concern is that the government may access the data, whether it's covered by HIPAA or not is irrelevant, because HIPAA allows government access. Though yes, it would still be better than non-HIPAA in general.

I will once again proselytize for the new pebble time 2 (I am quite a fan of it). Open source and comes with standard sensors for health monitoring (6 axis imu, heart rate monitor, SpO2). Health data can be kept and analyzed on your phone and there are various apps that can do so. Suffice to say there are “surveillance-free” options out there, and if you’re not satisfied with current app options it is easy to hack your own together

Many times GadgetBridge* can be used instead of the official app

HIPAA is completely irrelevant to any of this. Ours is technically HIPAA complaint because the data they process is not subject to HIPAA.

In overly simple terms, if insurance is not involved, then it’s not subject to HIPAA.

I am using Withings in combination Tredict. Both GDPR-compliant.
