Campaign concept
A trusted device for calls, keys, and digital safety.
Built for privacy enthusiasts, founders, executives, crypto users, and anyone who wants fewer apps, less telemetry, and stronger control over sensitive conversations and credentials.
Focused security architecture
A secure element, encrypted voice, and a messenger you control.
TAUTAN Phone keeps critical identity data and communication workflows away from everyday smartphone clutter. The product is not a full phone replacement; it is a trusted device for communication, keys, and digital security.
Secure messenger
Private messaging is built around user-controlled protection levels and dynamic session updates inspired by Double Ratchet patterns.
Encrypted voice before the network
Secure Call compresses audio with the Opus codec and encrypts the stream on the device before it travels over LTE or Wi-Fi.
Two communication modes
Use it for everyday reachability or protected conversations.
Standard Call
Regular calls when you need to reach any number
Make ordinary GSM or VoLTE calls to any phone number for convenient day-to-day communication.
- Calls to regular mobile numbers
- Simple fallback for routine conversations
- Useful when the other person does not use TAUTAN
Secure Call
Encrypted calls between TAUTAN devices
Voice is encrypted on your device before transmission. The operator and network observers only see encrypted data.
- Works between two TAUTAN Phone devices
- Encrypted traffic over LTE or Wi-Fi
- Keys stay protected inside the device
Use cases

Digital autonomy
A compact device without unnecessary apps, marketplaces, or an overloaded ecosystem.
Crypto key protection
