Using pass + git now. Works great.
The only other issue we have heard of precisely one other time has to do with Firefox pinned tabs + some assortment of Firefox browser extensions. To be clear, any reproducible issues with syncing are 100% fixed as quickly as possible.
Lastly, regarding our API for syncing, while our encryption specification is described in plain text detail, you'd have to inspect our source to see how syncing works.
This was July or August of 2018 and Chrome on the desktop and Android.
I use working copy for accessing a git repo where I keep notes on my phone. It’s a great little app.
The only downside is I sometimes forget to commit and push, then expect docs to magically show up on my Desktop. I also wish it were a bit easier to add templates.
I’ve been building a markdown interpreter on top of that repo to parse some of the more structured parts of my journal into little graphs and things (so I can see how good I am at doing all my todos overtime, for example). I’m thinking about creating a sync system so I can get the real time saving, too.
I really, really want to just deal with plain files. So I think I’m going to try cooking up some sort of interface that commits to a git repo automatically/can spit out some templates and things, but have it be just git and plain files under the hood.
I use markdown formatting for everything, so it's easy enough to export if I want to. For my diary I've written a script that decrypts the files (one per day), concatenates them, builds and index and spits out a single HTML file.
