Protect your personal data and security with ChatMail. ChatMail provides an integrated end-to-end encrypted messaging protocol inspired by the world’s leading cryptographers. We encrypt your instant messages with ChatMail’s Advanced Messaging and Parsing Protocol (CAMP). These systems are unique to our network and encompass our Elliptical Curve Cryptography and PGP.

We boast a Key Exchange function for encryption and security that combines a cryptographic ratchet based on the DiffieHellman key exchange with a ratchet based on the key derivation function. When using ChatMail, external users default to basic PGP encryption, while internal users use Curve25519 with optional fallback to PGP encryption.

ChatMail is the first in the industry to identify both internal and external users automatically. Learn how you can protect your information with ChatMail.

Advanced Encryption & Security Protocols

CAMP Messaging Protocol

ChatMail uses an integrated end-to-end encrypted messaging protocol called CAMP. This protocol is based on both PGP and Elliptic Curve Cryptography, ensuring secure communication.

Identification Of Users

ChatMail automatically identifies both internal and external users. External users default to basic PGP encryption, while internal users use Curve25519 with optional fallback to PGP encryption.

Authentication Codes

ChatMail uses HMAC with SHA256 for message authentication. HMAC provides a secure way to verify message integrity by calculating a hash of the message and a secret key.

Double Ratchet Algorithm

The key exchange in ChatMail is based on the Double Ratchet Algorithm, combining the cryptographic ratchet with Diffie-Hellman key exchange and a ratchet based on the key derivation function.

DH Ratchet

ChatMail uses Elliptic curve Diffie-Hellman (ECDH) with Curve25519 ensuring secure key exchange, allowing forward secrecy. Attackers won’t be able to decrypt past messages even with an access to past session keys.

Symmetric Encryption

ChatMail uses AES-256 in Counter Mode (CTR) for symmetric encryption, ensuring that messages are securely encrypted. This encryption algorithm is widely recognized as a secure method for encrypting data worldwide.


Create and customize regular and anonymous groups with ChatMail’s group function. Customizable permissions for groups include voice messages, picture messages, contact sharing, mandatory message expiration, and groups’ shutdown.


Manage your contacts with your contact directory. With this feature, you can quickly add a user, view your blocked contacts, and easily backup and restore your entire directory. Prevent the unexpected. Be sure to back up your directory regularly.


ChatMail has the unique ability to use multiple encryption algorithms within the same application. Colors distinguish conversations for easy reference.

Represents external PGP email conversations with other providers.


ChatMail’s custom camera utilizes an advanced compression algorithm to give you the best image quality with the smallest file size. This process allows for near-instant picture messaging. Our custom-designed camera provides additional security benefits by controlling and preventing the storage of unencrypted cached image data on the device.


Confidently store your personal and professional notes in your encrypted notebook. By integrating the Notebook into ChatMail, you can:

  • Prevent the need for sharing data between device applications for a secure and unified experience
  • Include text and pictures in your notes
  • Easily share your notes with others
  • Fully encrypt your notes with your personal KeyStore password

Inside a Conversation

ChatMail incorporates the latest in design standards to create a powerful yet easy to use encrypted messaging experience. Messages automatically delete after a maximum of 7 days, and a maximum of 30 days for favorited messages.

You can enable typing and read receipts in your ChatMail profile settings. For the feature to work, both ChatMail users must have either typing or read receipts enabled. When read receipts are enabled, you will receive a second check mark letting you know the user has read your message.

Frequently Asked Questions

Our FAQ section addresses the most common inquiries surrounding our solution.
Let us guide you through this informative journey, empowering you with the information you seek.

What Is ChatMail? Is It An APP? Is It A Device?

ChatMail is an exclusive mobile security solution comprised of a custom-built communications application reinforced by a hardened Google Device using BlackBerry UEM technology. ChatMail 2.0 excels in offering privacy rich features with multiple layers of encryption protocols enabling encrypted calling, messaging, voice, photos, notes, and anonymous group chat. ChatMail: Engineered for security. Designed for privacy.

What Mobile Device Management Solution Does ChatMail Run On?

ChatMail offer two different types of device management solutions:

  • Android For Work (AFW) powered by BlackBerry® Unified Endpoint Management (UEM). UEM allows partners to secure publicly available off-the-shelf devices. For extra security,  virtual server is not run on instance of UEM on their cloud. Self-hosted instance is run, in own private data center, to prevent unauthorized access and intrusion. BlackBerry cannot push apps to a ChatMail device.
  • Renati Mobile Device Management (RMDM) controls ChatMail’s custom hardened mobile operating system. In-house development team approaches gaps in mobile security by implementing a Zero Trust security framework. By changing how Android itself is architected — focusing on both the client and server-side technology — we give clients the strongest security available for managed devices. RMDM uses no third-party software and will be offered as an alternative to BlackBerry UEM. Renati is currently in beta testing, slated to launch mid-2023.
Where Do You Backup And Restore The User Data When You Claim Serverless Storage?
  • ChatMail forces you to use a strong password. Only the device associated with your backup can attempt restore and only your password can retrieve the backup. You cannot access backups from anything other than a ChatMail device.
  • We do not use rosters. We do not use group storage. We do not store email. We do not store chat messages.
  • Contacts are shard across databases and only your device associated with the backup can access them. They are also encrypted by you and only you.
  • If your device is lost, wiped or stolen, you will lose everything. You don’t have to back up your notes or contacts. It’s optional.
Can I Communicate With Other Companies That Offer PGP Encryption?

If the other provider has followed the proper implementation guidelines, you will be able to communicate with them. Please note, if you receive a red “Message could not be decrypted” error it may mean the other company is sending unencrypted messages. By design ChatMail will not allow you to read or reply to unencrypted messages.

Could My Messages Be Decrypted, For Example If You Were Required To By Law Enforcement?

No, the keys used to decrypt messages are stored only on the user device. We have no access to a users’ device making decryption or altering a message in transit impossible.


Can I Send Multimedia Messages On ChatMail?

Yes, you can send pictures and voice messages on ChatMail, and they are encrypted like regular messages.


How Does ChatMail Protect Against Eavesdropping?

ChatMail uses end-to-end encryption to protect against eavesdropping. The encryption keys are only accessible to the sender and recipient.

How Does Encrypt Your Mobile Sell ChatMail Powered Devices?

EncryptYourMobile sells ChatMail powered devices that have ChatMail pre-installed and optimized for use on those devices.

Why Does EncryptYourMobile Sells Devices With Blocked Access To The Google Play Store?

ChatMail blocks access to the Google Play Store to prevent the installation of third-party apps that may contain malicious software and compromise the security of the device.


What Security Features Are Included In EncryptYourMobile Devices?

EncryptYourMobile devices include security features such as the removal of internet browsing, disabled GPS, USB, and Bluetooth, which prevents location tracking and reduces the risk of malware infections.
