I use Home Assistant for similar purposes, with Influx DB and Grafana. There are many integrations to automatically populate data. For example, I have heart rate data from my Apple Watch flow in so I can view it in Grafana.

I’d look at karlicoss’s personal data infrastructure for inspiration (or perhaps deterrent).
Deterrent is right. That graph is terrifying! I feel their frustration regarding getting data from Android apps. Part of what got me started thinking about this was when I realized that the years of data I entered into my fitness pal was suddenly locked behind a subscription service :-( Thanks for sharing!
Wait My Fitness Pal went subscription model? Also, pay once, export once, cancel?
Not entirely, just for some features, including data export past a certain date iirc. I probably will wind up doing just that though if I cannot figure out how to get the data off my phone. Right now the phone app is the only place I can even see that the data exists, so I'm slightly afraid of changing anything in mfp lest it 'sync' my data out of existence 😕
Oof on that last one. I know for experience how some apps handle sync and poof data is gone forever.
Damn, that's as fascinating as it is daunting. Some impressive dedication in there regardless!
Brainstorming a bit, I think wiring up InfluxDB, Grafana plus some convenient way of inputting all those data sources sounds ideal. As a time series database, keeping track of how data evolves over time is InfluxDB's whole thing, Grafana or similar would be for visualizing said data. I guess the complicated part would be getting your data sources to write to it in a convenient way, not sure if there's a generic enough project out there already.
Looking around a bit, not too dissimilar to what this blog post has done.
Thanks for the suggestions. At a quick glance, grafana looks to be perfect for the visualization aspect (at least in terms of capabilities). Glad to see there are free utilities for that and I might not have to resort to chicken scratch html/pyplot :-) I have yet to dig into influxDB still...
It's not exactly what you're asking for, but you should check out the opensource Android app Track & Graph. It's also on F-Droid
It's a local app though, I don't think it has any sync function.
Nextcloud notes support markdown. It may be a starting point.
