# A private, offline journal that asks nothing of you.

_One file. One password. 
Yours forever. No accounts, no cloud, no algorithms reading your three-in-the-morning thoughts._

The Sealed Journal is a single self-contained file. You open it in any modern browser and it locks behind a passphrase only you know. There is no signup, no email, no server somewhere caching your sentences.

Your words are encrypted with AES-256-GCM before they ever touch your device's storage. We can't read them. No one can — except you, with the passphrase you chose.

If you forget the passphrase, the data is mathematically inaccessible forever. That isn't a flaw. It's the whole architecture.

## Questions

### Does a private offline journal still work without internet?

That is the whole design. The journal is one HTML file your browser opens from disk, so a plane, a tunnel, or a dead router changes nothing about whether you can write.

### Where are my entries actually stored?

In your browser's local database on that specific machine, encrypted with AES-256-GCM before they touch disk. Nothing is uploaded, because there is nowhere to upload to.

### What happens to my writing if the company disappears?

Nothing. You already have the file. There is no licence server to phone home and no subscription to lapse, so the journal keeps working long after we stop shipping updates.

## Price

The Sealed Journal is a one-time purchase of $24 (introductory price, rising to $29). No subscription, no account, lifetime updates, 30-day refund. Buy at https://sealedjournal.com/#pricing
