Zero Knowledge, Truly
Zero-knowledge, in the literal sense.
We have no servers, no database, no backups of your writing. There is no copy for us to lose, leak, or be subpoenaed for.
Most "zero-knowledge" apps still hold ciphertext on their servers. That ciphertext is one bug, one breach, one warrant away from being relevant to you.
The Eternal Journal holds nothing. The encrypted blob lives in your browser's storage. The key lives in your head.
Architecture is the only honest privacy policy.
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.

- ·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 does zero-knowledge mean here?
It means the plaintext never exists outside your device. There is no server holding ciphertext either, so the usual zero-knowledge caveats about metadata do not apply.
Could you be compelled to hand over my entries?
We cannot hand over what we never receive. There is no database of users, entries, or keys to subpoena.
Is metadata like entry timestamps exposed?
Timestamps live inside the encrypted store on your machine. They are visible to you and to nobody else.

AES-256-GCM with PBKDF2 key derivation at 600,000 iterations — the OWASP 2024 recommendation. Done in your browser, not on a server.
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.
A journal that doesn't track you. At all. Ever.
No analytics. No cookies. No third-party scripts. No "anonymous usage data." If you view the file source, you'll see for yourself.
Your journal lives on your machine. Not someone else's.
No syncing, no servers, no "your data is safe with us." Local storage, encrypted, yours.
No account. No email. No "create your profile."
The Eternal Journal asks for one thing on first run: a passphrase you choose. That's it. That's the entire onboarding.
An offline writing app that genuinely works offline.
Once the file is on your machine, the internet is optional. Forever.

Comparisons
The Eternal Journal vs Day One.
Both are journals. They're built on opposite assumptions about where your writing should live.
By Location
GDPR-friendly by architecture, not by paperwork.
Most apps meet the GDPR with a stack of documents arranged around an unavoidable fact: they collect data. We arranged the software so there is nothing to document.
The cursor will be there when you return.
Centered. Blinking. Patient.
