Field-grade end-to-end encrypted voice calls. Zero metadata. Zero trust required. Built with Rust cryptography for operators who demand absolute privacy.
Every architectural decision puts your privacy first. No compromises.
XChaCha20-Poly1305 AEAD encryption with X25519 key exchange. Every call gets a unique session key. We can never listen in.
No call logs, no contact uploads, no tracking. Your IP is masked through relay routing. We store nothing about your communication.
The complete source code is on GitHub. Don't trust us — verify our security claims yourself. Full transparency.
The cryptography core is written in Rust for memory safety. No buffer overflows, no use-after-free. Independently auditable.
Opus codec at 48kHz delivers natural voice quality even on poor connections. Adaptive bitrate for WiFi and cellular.
Double Ratchet protocol ensures that compromising one key doesn't expose past or future calls. Every session is independent.
No accounts, no phone numbers, no personal data required.
Download from Google Play or sideload the APK. No registration required.
Your device creates a unique X25519 key pair locally. Keys never leave your phone.
Exchange your anonymous SecureCall ID with your contact via any channel.
End-to-end encrypted channel established. No one intercepts — not even us.
We don't ask for trust. We provide proof. Every claim is auditable.
Every claim is backed by real tests on real devices. No marketing fluff.
