MINIMALISTIC
DESIGN

The cgPhone app offers you secure telephone calls with the best voice quality and secure text messages – always protected through encryption. The interface is intuitive and user-friendly. And if you’re used to using a regular iOS or Android telephone app, you’ll be comfortable using cgPhone right away.

Once you’ve exchanged secret keys during an initial telephone conversation, all other calls and text messages will be securely encrypted and can only be decrypted by the other device. cgPhone uses complete end-to-end encryption during both telephone calls and chats. Simple and secure.

cgPhone Online is your SaaS app for your common iOS or Android device, and requires no further server installation. That means it’s especially well suited for small and medium sized groups.

MULTI
PLATFORM 

The cgPhone app is your multi-platform app for iOS and Android. For the “software only” version, you don’t need anything besides the app installed on your common device. You can use cgPhone on both your smartphone and your tablet. You just need your individual activation code, and you can use encrypted communications right away.
