Encrypted Phones

Spartan PGP offers a range of encrypted smartphones, using the latest anti-surveillance tech to secure your privacy.

Control Over PGP Keys

Our handsets come with a proprietary PGP-encrypted email client. The cryptographic key pair that you use to encrypt and decrypt messages is created by you on the device. How and where you store them afterwards is up to you.


Spartan PGP does not have copies of the users’ keys.

Pure P2P Messaging

Spartan PGP’s chat app uses OMEMO and OTR encryption to secure your messages. We have designed the service in a way that guarantees that your messages never touch our servers.


All communications happen directly between you and your contact’s device. If you try to send a message and the recipient is offline, the message does not leave your device unless they come online.

Untraceable Calls

Spartan PGP’s devices come with a proprietary ZTRP-encrypted voice call app. Unlike encrypted chats and emails, voice calls leave no messages behind.


ZRTP creates an encrypted soundwave, which travels over the air in ciphered form, and disappears the moment it enters the recipient’s ear.

Chip-Off Protection

Chip-off is a technique that forensics specialists use to extract the memory chip from a device to access the data stored on it. Spartan PGP’s handsets have full disc encryption, protecting the data against such techniques.


Everything on the device is encrypted. Even if the chip is extracted, the data on it is of no use without the decryption key, which only you have.
