Single-use, one-to-one, e2e encrypted chat.

Private Conversations

What is

throwaway is an in-browser messaging app. It’s specifically for single-use, one-to-one, e2e encrypted messaging. This means your messages are encrypted in your browser, and they are only decrypted when they reach your recipients browser. The messages disappear permanently once both browser windows have closed. You can never recover a throwaway chat; once the window is closed, it’s gone forever.

Secure Communication

How does it work?

ECDH (P-521)

throwaway creates a single-use public-private key pair for each participant.

AES-GCM (256)

After sharing public keys, each participant derives a symmetric key for every message they encrypt/decrypt.


Encrypted messages are passed between participants over a secure connection.
