End-to-end encrypted · no account · self-destructing

From one device to another
in five seconds.

Send text, passwords and files between your computer and phone, live and end-to-end encrypted. No app, no account, no cable. The key stays in your browser; the server only ever sees encrypted data.

New session

You get a room code, a password and a QR code for your other device.

Duration
Everything is deleted automatically when it expires.

Join

Enter the room code and password from your other device, or paste the link.

Room code

Zero-knowledge encryption

AES-256-GCM in your browser. The key is derived from the password and never goes to the server, so not even we can read your content.

Live, without conflicts

CRDT editor: type on both devices at once and nothing gets lost. It keeps working through brief connection drops.

One-time secrets

A password can be viewed only once, then it is deleted from the server. The clipboard clears itself after 30 seconds.

Files over the internet

Drag or paste (Ctrl+V) a file or screenshot. It is encrypted in chunks before sending, up to 200 MB.

QR for your phone

Scan it and you are in the room, no typing. The link carries the key in a part that is never sent to the server.

Device control

See who is in the room, lock it, and remove devices remotely. You get a warning on every failed attempt to join.

How it works

Create a session

Your browser generates the password and key. The server only gets proof that you know the password, never the password itself.

Open it on another device

Scan the QR code, open the link, or type the 6 digits and the password. Up to 8 devices.

Type, paste, drag

Everything shows up instantly. When you are done, destroy the session or let it expire.

Frequently asked questions

Is Twinpad free?

Yes. There is no account, no subscription and no ads. Open the site, create a session and start sending.

Do I need to install an app?

No. Twinpad runs in any modern browser on Windows, Mac, Linux, iPhone and Android. You can add it to your phone's home screen if you want it to feel like an app.

Is it really end-to-end encrypted?

Yes. The encryption key is derived from the session password in your browser and never sent to the server. Text, secrets, files, file names and device names are encrypted with AES-256-GCM before upload, so the server only ever stores data it can't read.

Do my devices need to be on the same Wi-Fi?

No. Twinpad works over the internet, so your phone can be on mobile data while your computer is on a different network.

How big can files be?

Up to 200 MB per file and 1 GB per session. Files are encrypted in 1 MB chunks and up to three transfers run in parallel.

How long is my data kept?

Only as long as the session lives: 15 minutes, 1 hour, 8 hours or 24 hours, whichever you choose. When it expires or you destroy it, everything is deleted from the server.

How many devices can join a session?

Up to 8. You can see every connected device, rename yours, remove others, and lock the room so no new device can join.

What is a one-time secret?

A password or token that can be opened only once. The server deletes it the moment another device opens it, and the sender is notified.
