Mini Diarium information
What is Mini Diarium?
An encrypted, local, cross-platform journaling app
Mini Diarium keeps your journal private. Every entry is encrypted with AES-256-GCM, the app never connects to the internet, and your data never leaves your machine. Built with Tauri, SolidJS, and Rust.
Features:
- Key file authentication: unlock your diary with an X25519 private key file instead of (or alongside) your password, like SSH keys for your journal. Register multiple key files; manage all auth methods from Preferences. See Key File Authentication for details.
- AES-256-GCM encryption: all entries are encrypted with a random master key. Each auth method holds its own wrapped copy of that key, so adding or removing a method is O(1), with no re-encryption of your entries.
- Rich text editor
- Calendar navigation
- Import: Mini Diary JSON, Day One JSON/TXT, and jrnl JSON with merge conflict resolution
- Export: JSON and Markdown formats
- Themes
- Automatic backups: backup on unlock with rotation
- Statistics
- Preferences: first day of week, future entries toggle, title visibility, spellcheck, password change, authentication method management
- Cross-platform: Windows, macOS, and Linux
- Zero network access: no telemetry, no analytics, no update checks

I have been using the application for a couple of days. Honestly, I think it is perfect and I would like more people to know about it.
You can lock and unlock the journal. +1 You can use a password or an encrypted key +1 You can edit past entries, and if you wish future entries as well +1 As it is stored locally you can decide in which location of your hard drive the journal is stored, and it will also remain encrypted +2. And if you fear losing it, you can make a backup because you have your journal and not someone else. It doesn't need internet. Another function that I like is that you can add photos or titles to your entry. One day can have several entries, that is excellent. You can add tags to each entry and import markdown files, excellent if you will migrate from another application.
I hope the application continues improving, I think keeping a journal is important and I consider that with Mini Diarium I can achieve it without having distractions.
