Holy hells, recently I did some research on fitness trackers because my doctor wanted some regular vitals as I pretty much only come in to the office when sick.
Most of them are absolute privacy nightmares and only handful of companies even let you opt out of data collection and processing.
Somehow they don't classify vitals and sleep data as health data under HIPPA in the US... wtf.
@wobblewuffess yeah they're awful like that, so are a lot of apps tbh. I've got an entire privacy layer sandwiched into my phone's OS so I can spoof data to apps for that exact reason.
