General information
- Secure Communication
End to End secure communication, messages and Calls, can only be conducted between two or more devices that are using the Kaymera (CipherBond / CipherFort) which are set up on the same server environment.
both sides require internet connection during the time of the communication (Wifi / 3G/4G data)
The indication you are currently having a secure call is green lock sign on the upper right side of the dialer application
- Semi Secure Calls
If this option is enabled, calls from your device to a non-secure device will be encrypted on your side only, meaning they will not be encrypted on the device you called to, so they can be traced if the other side is being observed.
The indication you are currently having a semi secure call is orange lock sign on the upper right side of the dialer application
- Non-Secured Communication
You can use CipherBond App for initiating none secure communication from the contacts section in the application, but the communication will be open with the regular dialer / message’s application.
Secure calls
Secure /semi secure calls

taping on the contact will initiate the call.
Note: this list contains both secure and not secure numbers

Settings
To open the settings, open the CipherBond application, click on the 3 dots and select settings.
There are many different configuration options in the settings, which are very self-explanatory.
I would like to focus only on the most common ones:
- Secure calls enable / disable - disabling this button means that even calls to secure number will be done with regular dialer
- Semi-secure enable/disable – for phones who have the semi secure option only.
disabling semi secure calls means that calls to non-secure numbers will be done regular dialer while calls to secure number only will be done by CipherBond in a secure way. - Private mode – keep your number disguised.
- Time limited message expiry time – this is where you define how much time before TLM message will be deleted itself.
