Time for me to shine! I use 2 giant plain-text files. One for notes. The other for to-dos. I use git to sync to a private git repo using my own app https://github.com/tanin47/git-notes (work with Mac, windows, Linux) My priority is that I want my notes to live forever. Using GitHub seems to achieve that purpose. (I used many notes app before which I threw away when moving to a new app)
I am curious how many people at least tried Git/GitHub in their note keeping journey to keep their notes safe and secure and accessible.
Using text files for notes is meh. I've just been pointed at Bear app, and using tags to manage grouping specific notes has been really nice.
