# An offline writing app that genuinely works offline.

_Once the file is on your machine, the internet is optional. Forever._

Most "offline-capable" apps degrade quietly the moment a sync fails. The Sealed Journal has no sync to fail.

Take it on the train. Take it to the cabin. Take it on a forty-one-day Atlantic crossing if you must.

Your words don't need a connection to exist.

## Questions

### Is this a native app or a browser app?

A browser app that behaves like a native one. A single local HTML file, no installer, no app store, no update mechanism reaching over the network.

### Does it work in full screen without distractions?

Yes. Full-screen mode hides the browser chrome, leaving the centred cursor and nothing else.

### Will it run on Linux, Windows, and macOS?

Anywhere a recent Chrome, Firefox, Edge, or Safari runs. The file does not care about the operating system underneath.

## 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
