The desktop app is where MoodHaven started, but your thoughts don't always wait until you're at your computer.
Here's how MoodHaven works when you're away from your desk.
In Your Browser
journal.moodhaven.app is the full MoodHaven experience in any browser — desktop, tablet, or phone. No install required.
The browser build uses IndexedDB instead of SQLite, but the encryption model is identical: AES-256-GCM with a PBKDF2-derived key, all in your browser's memory. Your journal never leaves your device, even in the web-hosted version.
It works offline. Write without a connection, come back later.
On Your Wrist: Wear OS Companion
The Wear OS companion app is built for the moment a thought arrives before you can reach for your phone.
Tap to record. The app captures your voice as a local audio file — 16 kHz mono, no upload, no cloud speech API. When you're back at your desktop, MoodHaven transcribes it using whisper.cpp, a local inference engine that runs entirely on your machine.
The transcription lands in a review queue. You edit it, add context, set a mood, and it becomes a journal entry. The audio file is deleted after transcription.
How They Connect
The desktop app is the hub. The browser app and Wear OS companion connect to it — through encrypted WebDAV sync to your own storage, or directly over your local network with LAN peer sync.
Neither path routes data through MoodHaven's servers. Your entries travel as ciphertext between your own devices.
The Privacy Model Holds Everywhere
Whether you're writing on your phone's browser, speaking into your watch, or typing at a keyboard — the rules don't change:
- Journal content is encrypted before storage
- Audio is transcribed locally, never sent to a cloud API
- No account required to start writing
- Sync uses your own storage, not ours
The desktop app for Windows, macOS, and Linux is available on the download page. The browser app is at journal.moodhaven.app.
