  There's a desktop version that seems to run offline.

  No data transacts to any server. It's just a static client side site that stores data in your browser's LocalStorage. And it does run on desktop as a standalone application (5 MB!)

  Have a look at the source, there is no server for this at all, it's a front-end only app. It's published via Netlify. You can also run it on docker locally.
