Top secret

Read once.
Then poof.

Share passwords, keys and private notes with a link that self-destructs. It's locked in your browser before it leaves, so not even we can peek.

The key never leaves your browser. We only ever store scrambled text.

Three steps. Zero traces.

No sign-up, no app. Works on any phone or laptop.

  1. 01

    Write it

    Your browser locks the message with a brand-new key. Only scrambled text reaches us.

  2. 02

    Send the link

    The key rides along inside the link. Paste it in any chat, or let them scan the QR code.

  3. 03

    Poof

    Once it's read, or the timer runs out, it's shredded for good. Nobody gets a second look.

No peeking

Built so nobody can snoop.
Not even us.

The secret key lives in the part of the link after the #. Browsers never send that part to a server, so it never reaches us.

  • Locked in your browser

    AES-256 encryption happens on your device, before anything is sent.

  • Safe from link previews

    WhatsApp, Slack and mail scanners can't burn it. Only a human tap opens it.

  • You set the rules

    Timer, view limit and password. Shred it early from your private manage link.

  • Stored in the EU, no trackers

    Encrypted messages are kept only in EU data centres. No ads, no cookies, no analytics on message pages.

Good questions

Can you read my messages?

No. Your browser encrypts the message before sending it, and the key stays in the link. We only hold scrambled text, and we delete even that once it's read.

What if the link preview in WhatsApp opens it?

It won't. The link opens a "Show the secret" screen first. Nothing is read until a person taps the button.

Is it really free?

Yes. No account, no ads. Companies can pay for their own branded version, which keeps the lights on.

How long do messages stay?

From 5 minutes to 30 days, your pick. Whatever comes first, the timer or the last allowed view, shreds it.
