Send it.Use it.It deletes itself.

Files, photos, text and code between your devices —or to anyone you like. They arrive whole, in seconds, and in five days they delete themselves.

Universal clipboard

Like your clipboard, but across all your devices.

Copy something on your phone and paste it on your computer: a link, an address, a paragraph, a file. No cables, no matching device brand, no need for the same account everywhere.

  1. 1

    Copy

    On any device. Text, screenshots, files, anything.

  2. 2

    Paste at zas.red

    Paste it on the page and you are done. No forms, no folder to choose.

  3. 3

    It is everywhere

    It appears instantly on your other devices —and you can pass it to someone with a link.

JavaScript
// se parte en chunks antes de salir
async function upload(file) {
  const parts = await split(file, 4 * MiB);
  return Promise.all(parts.map(send));
}

If it is code, it arrives as code: monospaced, coloured, with the language set.

And unlike your clipboard, the next copy does not replace it: it lives for 5 days.

The replacement

Everything you used for this.

Instead of

Emailing yourself

You send it from the phone and it turns up on the computer. Open it, use it, and in five days it leaves on its own.

Instead of

WhatsApp

The photo arrives with the megapixels it had. You pass it on with a link, and whoever gets it opens it without an account.

Instead of

Drive or Dropbox

They arrive, you use them, they go. In five days the list clears itself: no folders to build and no second place with thousands of files to maintain. Whatever you want to keep, you pin.

Instead of

A USB stick

You turn on Direct and Zas tries to connect the two devices. If the network requires it, Zas uses a relay. The file travels encrypted, is not stored, and uses none of your storage. Both devices need Zas open.

The corridor

A corridor, not a warehouse.

Everything you send starts with a 5-segment ring: one for each day. When the ring goes dark, the item deletes itself. Nothing piles up and nothing waits for you to organise it. If something needs to stay, pin it —and its clock stops until you release it.

Day 1

just arrived

Day 3

3 left

Last day

gone tomorrow

Pinned

stays as long as you want

Always encrypted.

Zas encrypts content on your device. The database and object storage receive encrypted data, not open content.
