ID Caller

Live

Private audio and video calls without a phone number, email or sign-up.

ID Caller is a calling app built around privacy. There are no accounts and no forms: your identity is a 12-digit ID and a key pair generated on your device. Only people you have explicitly linked with can call you — by QR code, a one-time code valid for 30 minutes, or a confirmed request by ID — so spam is ruled out by design. One-on-one calls go directly between devices over WebRTC and are always encrypted with DTLS-SRTP; a relay is used only when a direct connection is impossible. Contacts and call history stay on your device.
