PCall

Encrypted chat and calls with no phone number, no email and no password.

Your account is a key, not a record we keep

When you first open PCall it generates a key pair on your device. The public half — an address that begins pyra1… — is what other people add to reach you. There is no sign-up form, no phone number, no email address and no password, so there is nothing to lose in a breach and nothing for us to hand over.

You add someone by scanning the QR code on their screen. It carries their address, their display name and the public key their messages are encrypted to.

What is encrypted, and what is not

• Chat messages are end-to-end encrypted, always. A group chat sends one separately encrypted copy per member rather than a shared key.
• One-to-one call audio and video are end-to-end encrypted too — through the relay server under a key both devices derive on their own, or directly between devices with each side's fingerprint signed by its identity key so the server cannot substitute its own.
• Group calls are not end-to-end encrypted. There is no shared key for a group to encrypt under, and the app says so on the call screen rather than leaving you to assume otherwise.
• Posts, comments and likes in the Social tab are not encrypted. They are stored on our server in the clear and shown to your mutual contacts.

The recovery phrase is the only way back

Twelve words, shown once, saved by you from Settings → Backup. They restore your identity on a new device. We never see them, they are never sent anywhere, and we cannot reset them — if you lose them, the account is gone. That is the cost of an account nobody else can open.
