Tap to start a secure call

Technical details
  • End-to-end encrypted — Only you and the other person hold the keys. No server — not even ours — can decrypt your audio or video. Your call content is completely inaccessible to any third party.
  • No logs — We do not log any call data, connection metadata, IP addresses, or usage analytics. There is no database — nothing to hack, subpoena, or leak.
  • Full anonymity — Your IP address is never exposed to the other participant. All media is routed through a TURN relay so neither side learns the other's location or network identity.
  • Fully hosted in Switzerland — All infrastructure — signaling, relay, and static assets — is hosted in Switzerland. Your data is subject to Swiss data protection regulations, not US, EU, or any other jurisdiction.
  • Double encryption — Every call is protected by two independent encryption layers: WebRTC DTLS-SRTP and an additional AES-256-GCM layer using the Encoded Transform API.
  • Encrypted signaling — Connection setup messages are encrypted client-side before reaching any server. Derived via HKDF-SHA256, only someone with your room link can read them.
  • TURN relay — All media is routed through our Swiss-hosted relay. Neither participant reveals their IP address to the other. The relay cannot decrypt any content.
  • Safety numbers — A verification code derived from both participants' cryptographic fingerprints (SHA-256) lets you confirm no man-in-the-middle attack occurred.
  • Metadata minimization — Internal network addresses and device identifiers are stripped from all connection data before transmission.
  • Zero persistence — Rooms exist only in memory while active. No database, no logs, no analytics. The source code is open for anyone to verify.
