iPhone

Encrypted notebooks that hold your files too: photos, PDFs, audio and video in folders, the same on PC and iPhone. Shape it your way. Your thoughts are yours alone. An encrypted notebook that keeps your notes and your files together: photos, PDFs, text files, audio and video. Location is clear. Encryption is provable. You choose where your data lives. It's stored under your own account, in whichever cloud service you use — no wondering where it actually is. When you encrypt a notebook, its contents become unreadable to anyone without the key — including your cloud provider itself. You don't have to take our word for it: open the encrypted files in your own cloud storage and see for yourself that they're unreadable without it. "Only you can read it" isn't a promise here. It's something you can prove. Not just notes — your files, too Photos, PDFs, text files, audio and video live inside the same notebook as your writing. Add them from your photo library, camera, the Files app, or by scanning documents, then sort them into folders, as many levels deep as you like. Encrypted notebooks keep their files encrypted in your own cloud storage. Your notebook is the same on your PC and your iPhone. On Windows, you can even mount a notebook as a drive. For daily journaling and organized notes alike - Diary mode: a simple, chronological record of each day - Regular notes: organize freely with folders, tags, and folios Choose whichever format fits each notebook. Your notes, shaped your way Change the look of your notebook freely, from a calm daily journal to an organized workspace. New themes keep arriving over time. Bring your own cloud Whichever cloud storage you already use — that's where it lives. Your storage is your own account. We're never in the middle. Buy once. It keeps getting better. The look and feel can adapt to how you think. A single one-time purchase (Glyph) unlocks it all — no subscription. It includes cloud sync, plus new themes as they're added over time (a few premium themes sold separately). Who it's for - People who want their journal or notes kept truly private - People who want to keep work and personal notes safely separate - People who want to choose their own cloud provider - People looking for an app with no ads, no tracking
