About

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
