Pryvate™ Encrypted Voice Calls (VOIP)

Voice Encryption

If you work in a profession with a need for secure communications, or you are concerned about possible invasions of your privacy, it is always best to use open-source, peer-reviewed encryption tools on your smartphone, tablet and desktop computer.

The Pryvate app for Android (2.2 or higher) and Apple (iOS 6.0 or later) features voice encryption capabilities that enable subscribers to make free voice over internet protocol (VoIP) calls that are secure, encrypted and completely private.

What is Voice Encryption?

Voice encryption refers to a voice message that is scrambled or coded so as to be unintelligible to an eavesdropper. The primary purpose of encryption is to protect the confidentiality of digital data that is transmitted across the internet or other computer network. This is achieved by converting electronic data into another form (called ‘ciphertext’) that cannot be understood by unauthorised parties.

Pryvate™ Encryption

By using military-grade encryption combined with RSA 4096-bit and AES 256-bit encryption, you can ensure that the calls you make are completely private, with no risk of data being intercepted by hackers, criminals or government surveillance agencies. We also use Diffie-Hellman (D-H) key exchange, MD5 and SHA512 hash for voice integrity, as well as our proprietary ‘Protection Agent’ software that detects, alerts and defends against ‘man-in-the-middle’ attacks.

Encryption keys are automatically created on your smartphone for each call, enabling individuals and businesses to gain the benefit of the best communication encryption on the market – as a result, we can guarantee that your calls are 100% secure.

Voice Call Quality – Multiple Network Compatibility

We provide an industry-leading encrypted voice service that operates over carrier-grade infrastructure. This enables calls to be made securely over a 3G/4G, GPRS, EDGE, LTE, UMTS, HSPA, W-CDMA or Wi-Fi connection, even at low bandwidths.


To ensure the utmost security for your voice calls, encryption keys are created on your smartphone for each individual call. These single-session-only keys are never stored or known to Pryvate, as the software works on a peer-to-peer basis with no servers in the middle, and therefore no record of calls is ever kept.

Automatic Discovery of Pryvate Contacts

To make using Pryvate easier and to ensure that you can take advantage of fully secure voice calls, you will receive an auto-notification when a contact becomes a Pryvate users. You will also be able to see when your Pryvate contacts are available, and their contact details will automatically populate your Pryvate address book.

Secure Conferencing

Even when you are conferencing with multiple users, all voice calls are encrypted. The conference call runs on the conference organiser’s device; they initiate the conference by calling the other parties and adding them to the group.
