Your Notes, Your Secrets — Reimagined. Welcome to a different kind of notes app. Designed for privacy, built for simplicity, and powered by a unique approach to hidden notes. # Truly Private Notes Create hidden notes that don’t appear anywhere in the app. No titles, no previews, not even a count. The only way to access them? Enter the exact passphrase you used to create them. If you don’t remember it, it’s like the note never existed. # Visible Notes, If You Want Them Prefer something more traditional? Mark any note as visible, and it will show up in your list. Easily switch between your private thoughts and everyday to-dos. # Raw Markdown + Preview Toggle Write in pure Markdown, and toggle to preview your note beautifully rendered. Focus on content first, then enjoy the polished result—no distractions, no clutter. # iCloud Sync Keep your notes with you, securely synced across all your Apple devices. # Dark Mode Thoughtfully designed for low-light environments, perfect for night writing or discreet journaling. Why You’ll Love It - Journal without leaving a trace. - Store sensitive thoughts or ideas without fear of exposure. - Draft blog posts, code snippets, or creative writing in Markdown. - Keep everyday notes visible, and hidden notes truly hidden. Minimal. Powerful. Private.
