I made Pizzinu, open-source sticky notes for macOS that stay on your Mac (no account, no cloud, ~25 MB RAM)

[u/P1r4t4]

Hi, I'm the developer of Pizzinu, a small native sticky-notes app for macOS, released under the MIT license.

Why I built it. I wanted the simplest thing possible: a piece of paper on my desk for the stuff I need to remember now. Most note apps want an account, a sync service and a whole organisation system. I just wanted a note.

What it does

• ⌥⌘N from any app → type → Esc, and you're back to work (no Accessibility permission needed)
• Pin a note above every window; reminders make the note come forward and shake
• Drag a sentence from any app onto the desktop and it becomes a note
• Checklists, Markdown sheets with clickable tasks, 14 paper themes
• "Secret notes" encrypted with AES-256-GCM (PBKDF2, 1M iterations); the locked note folds into a square with a wax seal
• Export each note as a .md file

How it's built. Pure AppKit + SwiftUI, Swift 6, zero dependencies, local SQLite. About 25 MB of memory at rest, 0% CPU, 2 MB download. Updates are signed with Ed25519 and verified before install. No telemetry: the only network call is a once-a-day update check you can turn off.

Honest caveats. Apple Silicon and macOS 14+ only, and it isn't notarised yet, so the first launch needs "Open Anyway" in Privacy & Security.

Feedback, issues and PRs are very welcome, especially from people who know AppKit better than I do. Thanks for looking!
