Absolute insanity. Why would anyone want to wear a 24hr tracking bracelet?
When you are required to carry a phone with you all of the time for your job you kind of get numb to it. It is stupid, I don't want this data going to anyone but me. You do you but it is what it is.
I'm suprised there isn't a self-hosted solution for this yet. Maybe there is... I've never looked into it.
I have looked around a little but the DIY community around those devices is not nearly as mature as one would hope. It is slowly getting there but it will probably be 5-10 years until there is something that can do everything a "commercial" product can do today unless someone gets really pissed off and decides its their life goal to make something like that.
I am pissed off enough but I don't have the needed background in the medical/hardware field and even if I spend the time to learn and build it there are projects out there that are already better than anything I would probably make (maybe?). I don't know. Life is just too damn busy for me at the moment to try to work on something like this.
