One File
A journal that's just an HTML file.
Open it in any modern browser. That's the whole installation.
One file means a few things at once: no installer, no permissions to grant, no app store to depend on, no update server that could one day disappear.
It also means you can read the source. The file is not minified.
It is, in the most literal sense, software you own.
The Typewriter Experience
The cursor stays. The text moves.
In Write mode, your cursor remains exactly at the centre of the screen. The page rises up to meet it. Past words fade into soft shadow at the edges, leaving the present sentence in clear focus. Switch to Read mode and the entry flattens into an evenly lit document — the fade is for writing; the flat light is for returning.
Radical Privacy & Encryption
AES-256-GCM, in your browser, with a key only you derive.
- ·PBKDF2 key derivation at 600,000 iterations — the OWASP 2024 recommendation. Existing journals upgrade transparently on first unlock.
- ·No accounts, no telemetry, no analytics, no cookies, no third-party scripts.
- ·IndexedDB storage with a localStorage fallback. Encrypted before it touches the disk.
- ·The file is not minified. You can read the source. We'd rather you trust it than us.
What It Does Not Do
- ✕No word counts chasing you across the screen.
- ✕No formatting toolbar wrestling your thoughts into neatness.
- ✕No cloud sync. No distant servers. Your words stay yours.
- ✕No social sharing. Your vulnerability is not content.
- ✕No AI assistant finishing your sentences.
- ✕No streak counters. No guilt. No gamification.
- ✕No subscriptions. No mood trackers. No noise.

Get The Eternal JournalQuestions
Is the whole app really one HTML file?
Yes. Markup, styles, and unminified script in a single document you can open, read, and archive.
Can I keep it on a USB stick?
You can, and some people do. Bear in mind the encrypted entries live in the browser store of the machine you write on.
Will it still open in ten years?
A plain HTML file with no dependencies is about the safest bet in software for long-term openability.
