For those browsing here there is a common term for "tracking personal data" this called "Quantified Self". If you are interested in it as a n00b like I am this will greatly help start your search into the hobby. There are a lot of people doing it out there and a bunch of outdated or abandoned projects. I have yet to find a modern one that does for QS what Home Assistant has done for home automation and data collection.

There is an excellent subreddit dedicated to QS - /r/QuantifiedSelf/. I learned one heck of a lot from that sub when I started out and there are some seriously intelligent people there. I've stood on the shoulders of those giants for 3.5 years.
