WTF is a "privacy-focused code editor?" They're just glorified text editors! They run locally! They don't connect to the Internet at all! How would they be anything other than "privacy-focused" by default? Why is this even a question?!

I fucking hate this timeline.

Anyway, to answer your question: emacs, obviously. Or vim if you're evil, I suppose. Or just whatever the Hell you want, because if your editor even has "terms of service" or a "privacy policy" of any kind something has already gone horribly wrong.
