A private notes app encrypts your notes before they touch a disk or a server, and leaves the key that opens them with you instead of with the company. NotePrivate works that way: your master key is sealed by your own password, that password never leaves your machine, and the app still opens your notes with the network switched off. It runs on macOS and Windows, the planned price is $59 per year, and it is not on sale yet, so every button on this page joins the NotePrivate waitlist.
Run these four tests on NotePrivate and on anything else you are weighing up. They are the whole difference, and each one is easy to check before you commit your notes.
