Probably I'm going to be downvoted as f*ck, but if it's for HTML, CSS and JavaScript the most privacy respecting option could be vim or, with a pinch of salt, Notepad++ if you are on Windows. If you are learning grab a good reference book or website (I used w3school like 20 years ago) and break things. On a personal level, I never liked the "training wheels" that some editors force into you. But, could be that this isn't a quite popular opinion 😅

Edit: some fat-finger typos
