Your journal is one of the most personal things you create. Where that journal lives matters more than most people stop to consider.
The Default is Someone Else's Server
Most journaling apps store your data on their infrastructure, encrypted with keys they manage. You're trusting that:
- Their encryption is real and correctly implemented
- They won't change their privacy policy
- Their business won't fail, be acquired, or pivot
- No breach exposes your data
That's a lot of trust to extend to a company you didn't choose to have a relationship with.
What Self-Hosting Actually Means
Self-hosting doesn't mean running a server in your basement (though you can). It means choosing where your backups go.
With MoodHaven, you can sync encrypted backups to:
- Your own server or NAS — MinIO, self-hosted WebDAV, anything S3-compatible
- Familiar cloud services — Backblaze B2, DigitalOcean Spaces, or similar
- Nothing — local-only is a completely valid choice
In every case, only encrypted blobs are uploaded. The service provider receives ciphertext. They cannot read your journal, even if they wanted to, even if subpoenaed.
Trust Through Verification
The difference between self-hosting and trusting a cloud journal isn't just technical — it's philosophical.
With a cloud journal, you trust the company's word about their encryption and privacy practices.
With MoodHaven, you can read the encryption code, verify what gets sent over the network, and confirm that no plaintext ever leaves your device. The trust is verifiable, not assumed.
For Non-Technical Users
You don't need to understand S3 or run a server to benefit from this. The simplest path is to use MoodHaven locally with no sync at all — your data stays on your device, encrypted, full stop.
If you want cloud backup, services like Backblaze B2 are straightforward to set up and cost a few cents a month for the amount of data a journal generates.
The important thing is that the choice is yours. MoodHaven doesn't make it for you.
The Broader Point
Privacy-first isn't just a feature. It's a design constraint that touches every decision: where data lives, who holds the keys, what gets logged, what gets synced.
MoodHaven starts from that constraint and builds outward. Self-hosting support isn't an add-on — it's the natural result of an architecture that refuses to trust any party with your unencrypted thoughts, including us.
