Wireless encrypted voice, video, messaging, file sharing between
users. Make sure your conversations are 100% private and that you are
only linked to the intended party.
All encryption is done on the device, no one can listen.
Technology Introduction
Privacy Protection
We create apps that allow people to communicate freely without
compromising privacy.
We have no access to any of your communications, and our
end-to-end encrypted infrastructure ensures that any
communications over our network remain private and accessible
only to you and your contacts.
We do not require personal information to register for an
account, such as email, phone number or name. We will not
collect any information without your consent.
Information Security Assurance
We use the most secure way to encrypt messages, using the double-gear algorithm for key exchange, which combines double-ratchet, pre-key and cubic elliptic curve Diffie-Hellman key exchange (3-DH), and Use Curve25519, AES-256 and HMAC-SHA256 algorithms as cryptographic primitives primitive). All encryption is done on your device. You have the keys and no one can listen, not even us. Entire communications—including group messages, photos and videos, files, voice calls, and even status messages—are always end-to-end encrypted. Unlike traditional messenger apps, the design excludes fallbacks for unencrypted connections.
