Locked on your device, kept in accounts you already have, like Telegram or GitHub. Nobody can open them. Not even us.
No card. No trial. There's nothing to upgrade to.

This is the app, with sample files. Click a file to open it, or drop one of yours on it.Tap a file to open it, or tap + to add one. Nothing leaves your browser.
Same files, from our side. And from Telegram, GitHub, GitLab or Hugging Face: locked pieces called a3/9f04c1e2b7d8e1.bin in a project called quick-loader-v2. Nobody can open them. Not even us.
How is it unlimited?
Link an account you already have: Telegram, GitHub, GitLab or Hugging Face. That's where your files will live. Not with us.
Your device cuts it into pieces and locks each one with a key made from your password. The key never leaves your device.
The locked pieces go to your account under dull names. When a spot fills up, zcrypt opens a fresh one. Telegram has no ceiling, so neither do you.
Scroll to drive it. Scroll back to undo it.

Start freeWhy trust it
Every layer is built for privacy, and every line of it is open source.
01 / ENCRYPTION
Your password makes the key, right on your device. We never get a copy, so there is nothing for us to lose, leak or hand over.
02 / SCALE
Big files are cut into pieces and spread across your accounts. Your only limit is the free space you already have.
03 / STEALTH
Pieces get dull names and ordinary commit messages. To anyone looking, it's one more quiet side project.
04 / OPEN
Read the code, check the maths, or run it on your own computer. You don't have to take our word for it.
What's inside
It just can't read your stuff.
Looks like a normal drive

Close the laptop, lose the signal, come back later. It picks up where it stopped. Deleted something by mistake? There's a restore button.

Why this exists
Google Drive tapped me on the shoulder at 15 GB and asked for my card. So I made a second account. Then a third. For a week I was splitting one folder across three logins like a low-budget digital smuggler.
TeraBox said one terabyte, free. What they did not say: the download button is hidden like a state secret, and the fine print treats your files as theirs to scan and learn from.
I uploaded a 4 GB folder, watched it crawl to 80 percent, and watched it fail. My first thought was not “let me retry”. It was “why am I handing my life to a company whose business is knowing what’s inside it”.
Free storage was never free. I just hadn't read the price tag. So I built the one with no limit and nobody reading it.
There is a team. It's me.

Price
Per month. Per year. Per forever.
There is no Pro plan. There is no Plus plan. There is definitely no Premium Ultra plan. Your files live in accounts you already have, so there's no warehouse to rent and nothing to bill you for.
Start freeWant to say thanks anyway? Star it on GitHub. It costs exactly the same.
Yes. There are no paid plans and no card. Your files live in accounts you already own, so there's nothing for us to charge for.
zcrypt doesn't keep your files. Your connected accounts do. Every account you add is more room, and Telegram has no ceiling at all. New accounts start with 1 GB of shared space while you set things up.
No. Files are locked on your own device before they're uploaded, and so are their names. We only know where the pieces went, never what's in them.
Then nobody can open your files, including us. That's what real privacy costs, so keep it in a password manager.
Not to start. You can upload right away. Connect an account whenever you want more room. Telegram is the easiest if you already use it.
Yes. Send them a link. You can add a password, an end date and a download limit, or use Send to make a file that disappears after one read.
The website does, in Safari. There's no iPhone app yet. There are apps for Mac, Windows, Linux, and Android (beta).
Then the pieces stored there are gone from there. For anything you can't lose, keep a second copy somewhere else too. That's good advice for every cloud, this one included.
Every line of zcrypt is public, so anyone can run it, including you. Once you connect your own accounts, your pieces sit there, not with us. Files in the 1 GB starter space live on a shared account, so if I ever wind it down, I'll say so well ahead of time and you can download everything.
Every line, under the MIT license. Read it, poke at it, or run the whole thing yourself with docker build and docker run.
