OwnJournal is a privacy-first journal app built on one idea: your data belongs to you. We don't store your journal on our servers — you choose where it lives. WHAT'S FREE • Write and edit entries with photos • Mood tracking with a 5-level emoji picker (great, good, okay, poor, terrible) • Tag activities — exercise, social, work, meditation and more • Mood calendar heatmap and statistics (distribution, trends, streaks) • Save and sync to your own cloud — iCloud, Google Drive, Dropbox or Nextcloud • Optional end-to-end encryption • Use across iPhone, iPad and Mac/PC • Available in 21 languages • Open source (AGPL-3.0) • No ads YOUR CLOUD, YOUR CONTROL Your journal lives in your cloud account — iCloud, Google Drive, Dropbox or Nextcloud. It is never stored on OwnJournal's servers, giving you full control over your data, seamless sync across all your devices and no lock-in to a single service. END-TO-END ENCRYPTION (OPTIONAL) With E2E encryption turned on, entries are encrypted on your device with AES-256-GCM. Only you hold the keys — neither we nor your cloud provider can read your journal. Zero-knowledge by design. MOOD & ACTIVITY INSIGHTS Track how you feel and what you did. Tag activities, see a month-at-a-glance heatmap colored by your daily mood, view distribution, trends, best/worst days and streaks, and filter your timeline by mood, activity or tag to spot patterns. Perfect as a minimalist mood tracker or a full journal — use as much or as little as you want.
