I very specifically want an app that collates all the information that can possibly be gathered about me in a way that I can utilize and abuse it myself. For me there is a lot of utility and value to be found with this sort of thing.
Of course the security posture of said app needs to be rather robust. And instead of it being an app it should instead be an SDK that I can then choose and control my own storage medium for.
The comment two above this links to a tool that literally does live syncing on a line by line level. Unless you’re editing the same lines at the same time you’re not going to get sync conflicts.
I use it as well and it works wonderfully in real time.
