Send a self-destructing message
End-to-end encryption. The key stays in the URL fragment (#) and is never stored.
Public network safety
Ideal on untrusted Wi‑Fi. Because the key is in the fragment (#), it is never sent over the network, even over HTTPS.
Zero plaintext
Your message is encrypted before it leaves your device. Only the ciphertext travels through our servers.
We can’t read it
We don’t have the key. If authorities asked for your data, we could only hand over unreadable ciphertext.
