Diary — 일기
A beautifully simple, secure personal journal. Write freely, attach photos, and keep your memories safe with password protection and AES-256 encryption.
Features
Diary keeps things simple: a calendar, a rich text editor, and strong encryption. No cloud. No accounts. Just your words, on your machine.
Lock your diary with a master password. Auto-lock kicks in after a configurable period of inactivity.
Browse entries by date with an intuitive monthly calendar. Dots mark days with entries so you never lose track.
Bold, italic, lists, headings, colors, and more. Write expressively with a full formatting toolbar.
Embed images directly in your entries. Attach multiple photos to capture every moment of your day.
Instantly search across all entries by content, title, or date. Find any memory in seconds.
Supports 14 languages including English, Korean, Japanese, Chinese, French, German, and more. Dates adapt to your locale.
Your entries are encrypted with AES-256. Data stays local — no cloud, no telemetry, no tracking.
Choose the look that suits you. Switch between light and dark themes from Settings.
Runs natively on Linux, Windows, and macOS. Same experience everywhere, built with Flutter.

A quick tour of the app: from the lock screen to the editor, search, and settings.
Your diary greets you with a clean lock screen. Enter your master password to access your entries. The app auto-locks after inactivity so your thoughts stay private.
Select a date on the calendar and start writing. The rich text editor supports formatting, headings, lists, and more. Content auto-saves as you type.
Express yourself with bold headings, colored text, numbered lists, and bullet points. The full toolbar puts every formatting option at your fingertips.
Attach as many photos as you like. Images are embedded directly in the entry so your visual memories live alongside your words.
Search across all entries by keyword, title, or date. The list view shows every entry at a glance with date, title, and a content preview.
Configure your password, lock timeout, data directory, and theme. Everything is designed to be straightforward and accessible.
Deleting an entry requires explicit confirmation. No accidental deletions — your memories are protected from mishaps.
