Most journaling apps today either quietly harvest your data or tie you to someone else's server.
I wanted something different.
The Problem
I've tried a lot of journaling tools. Some are beautiful. Some have great prompts. But almost all of them share a common flaw: they treat your private thoughts as data points to be stored, analyzed, or monetized on their infrastructure.
The idea that a company somewhere has a copy of your most vulnerable, honest writing — because you tapped "Sync" — bothered me more the longer I thought about it.
So I stopped using them.
The Vision
MoodHaven Journal was born from the belief that your inner world deserves protection, not exploitation.
It's a journaling and mood-tracking app designed around three rules:
- Store everything locally, encrypted at rest. Your words never leave your device unless you choose.
- Sync only encrypted data, optionally, to storage you control. We support S3-compatible services — MinIO, Backblaze, your own server. Your data goes where you send it, as ciphertext.
- Never track or monitor you, in any way. No analytics, no engagement metrics, no peeking.
It's built for people who believe that privacy isn't just about protecting data — it's about protecting space to reflect, heal, and grow.
Why Open Source
Building this in public matters. You shouldn't have to take my word for it that the encryption is real or that there are no hidden network calls. The code is on GitHub. Read it, audit it, contribute to it.
Transparency is part of the product.
Where It Is Now
MoodHaven has shipped mood tracking, AI-powered local insights, LAN peer sync across your own devices, a Wear OS companion for voice reflections, and a time capsule feature for writing letters to your future self. A mobile companion is in development.
None of it changes the core promise: your journal, your encryption, your control. Always.
The desktop app is free, open source, and available now for Windows, macOS, and Linux. Download it here.
