Summary

Diarium is a private journal app for recording memories with text, photos, videos, audio, locations, and tags. Entries support rich-text formatting, timestamps, templates, and multiple entries per day, with unlimited attachments. Users can revisit writing through calendar, timeline, map, gallery, attachment views, search, and “On this day” notifications. The journal database stays on the device by default, and no account is required. A password, PIN, or biometrics can protect the journal. Optional Pro Cloud Sync uses the user's OneDrive, Google Drive, Dropbox, iCloud, or WebDAV storage to sync supported devices; Diarium says it cannot access that personal cloud data. The app can import from other journal apps and export to Word, plain text, HTML, or JSON. It is available for Android, iOS, macOS, and Windows. There is a free plan, but Cloud Sync requires Pro on the platform being used; the paid Windows app includes Pro.
