I wanted a Markdown editor I could use anywhere — no toolbar clutter, no formatting menus, just text. Every device, same experience. But as a security engineer, I couldn't ignore that most notes apps can read everything you write. So I took the 1Password approach to encryption and applied it to note-taking: zero-knowledge, client-side, no one sees your keys but you. That's Scrinium.
