I've ended up in the same place, but I use a text file. After years of trying to use time tracking systems, TODO systems, and journaling systems, I could never get past their data-entry-inefficiency compared to just opening a text file in vim and typing. I do need a better way to view and report my data though, so what I've done is write a read-only reporting GUI that can parse my text file, give me daily/weekly/per-task/per-client reporting on my time tracking, per-day views of any journal entries, and a TODO list. It can even export the current week's entries in a format that pastes into my invoice spreadsheet template. This is all managed in a per-year text file, 2020.txt, that's easy to back up and could be version controlled if I needed to do that.
