Mini Diarium

Mini Diarium is a private journaling app for your desktop. All diary entries are encrypted with AES-256-GCM at rest — plaintext never touches disk. Your journal stays entirely on your machine: no cloud sync, no network connections, no telemetry.

Features include:

• AES-256-GCM encryption for all entries
• Multiple journals with independent passwords
• Rich-text editor (bold, italic, headings, lists, images)
• Calendar navigation and entry browsing
• Import from Mini Diary, Day One, and jrnl formats
• Export to JSON and Markdown
• Auto-lock on idle or OS screen lock
• Key-file authentication as an alternative to passwords
