Description
In an era where most journaling apps sync everything to the cloud, Mini Diarium‘s approach is to keep your journal stays fully offline, encrypted, and under your control.
Its a privacy-first desktop journal that stores all entries locally on your device using AES-256-GCM encryption. There are no accounts, no cloud syncing or servers involved. Your thoughts remain exactly where they belong, with you.
It is also the spiritual successor to Mini Diary, originally created by Samuel Meuli. Instead of simply updating the old project, the developer rebuilt the entire stack from scratch while keeping the same philosophy: simple journaling with complete privacy.
Use Cases
Mini Diarium works well for anyone who values private, distraction-free journaling.
- Personal daily journaling without cloud storage
- Writing private thoughts or notes securely
- Tracking habits and writing streaks
- Maintaining an encrypted digital diary
- Migrating journal entries from other apps

A Private Journal That Truly Belongs to You
Many journaling apps promise privacy but still rely on cloud services where your data ultimately lives on someone else’s infrastructure.
Mini Diarium make everything happens locally. Entries are encrypted before they touch disk, the encryption keys never leave your device, and the application has no network capability at all.
For writers who value privacy, data ownership, and simplicity, Mini Diarium is a digital journal that is truly yours and yours alone.
