OwnJournal – Your private journal, protected in your cloud

OwnJournal is a privacy-first journal app built on a simple idea: your data belongs to you.

We don't store your journal on our servers.

You choose where it's stored.

☁️ Stored in your own cloud

Your journal lives in your cloud account.

• Google Drive
• Dropbox
• Nextcloud

It is not stored on OwnJournal's servers.

So you get:

• Full control over your data
• Seamless sync across phone, tablet, and PC
• Access from any device
• No lock-in to a single service

Your cloud. Your control.

🔒 End-to-end encryption (optional)

With E2E encryption turned on:

• Entries are encrypted on your device
• Only you hold the keys
• We can't read your journal
• Your cloud provider can't read it either

With zero-knowledge design (we don't hold keys), your journal stays entirely under your control.

📊 Mood & activity tracking

Keep track of how you're feeling and what you did:

• 5-level emoji mood picker on every entry
• Tag activities like exercise, social, work, reading, meditation
• Mood calendar — a month-at-a-glance heatmap colored by your daily mood
• Mood statistics — charts showing distribution, trends over time, best/worst days, and streaks
• 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.

🧘 Simple, focused design

• No social features
• No followers
• No public posts
• No ads

Just a quiet place to write.

🔄 Use it on any device

Because everything is in your cloud:

• Write on your phone
• Continue on your tablet
• Read back on your PC

Everything syncs automatically.

You're not tied to one device.

✨ OwnJournal Plus (optional)

Try Plus free for 14 days.

Plus adds:

• Smart AI analysis – mood, emotions, and themes in your entries
• AI title and tag suggestions (now also suggests activities from your content)
• Activity Insights – discover which activities correlate with better or worse moods
• Mood and trend insights – see patterns over time
• Export to PDF and Word

AI only runs when you explicitly use it. The text you send is processed by third-party AI services (Google Gemini or OpenAI), but we don't store it on our servers. Plus is optional – the core journal works fully without it.

🔐 Minimal data collection

We collect only what's needed:

• Email for sign-in
• Display name if provided by your sign-in provider
• Anonymous diagnostics to improve stability

🔓 Open source

OwnJournal is open source under the AGPL-3.0 license. You can inspect the code, verify our privacy claims, and see exactly how your data is handled. No black boxes.

📔 OwnJournal is for anyone who wants:

• A journal app that respects privacy
• Their data in their own cloud
• A minimalist mood tracker or a full journal — your choice
• Sync across all devices
• AI when they want it, not forced on them
• No ads or social noise
• A journal they can trust for the long term

Your thoughts and records stay yours.
