Plus, enjoy monochrome icons as default, alongside bug fixes for a smoother experience.

Pixels 3a & 3a XL are not included in this release. Limited Edition and Renati 12 will follow in the coming weeks.

Renati supports Pixel devices by leveraging our advanced technology to overwrite the entire system and utilize our own custom certificates, ensuring partition authenticity which prevents unauthorized access. Renati now supports: Pixel 3a, 3a XL, 4 XL, 4a, 4a 5G, 5, 5a, 6, 6 Pro, 6a, 7, 7 Pro, and 7a.

Renati Optimizes Copy & Paste Functionality

Using the clipboard was one of the most requested features by our users. Depending on your threat model copy and paste can be dangerous. Advanced forensic extraction techniques exist that can potentially extract clipboard data stored in RAM. You will need to accept a disclaimer understanding the risks to use this feature. You can enable this feature by navigating to your system Settings > Security > Enable Copy and Paste

Renati Custom Apps: Calculator & Currency Converter Updates

Custom app updates bring sleek enhancements. In the Calculator app, enjoy new monochrome icons and a fix for arrow bouncing on Android 13. Meanwhile, the Currency Converter gets updated Kotlin dependencies and fresh monochrome icons for a refined experience.

Renati Automatic Wipe Feature

The device knows the last time it was successfully unlocked. If you have not unlocked your device within a set number of days the system will trigger an automatic factory reset. The device does not need to be online for this feature to work. This feature protects your confidential information in the event your device is lost or stolen. You can enable this feature by navigating to your system Settings > Security > Factory Reset on Inactivity

Renati Automatic Reboot Advantage

Automatic reboot helps to clean up any remnants left over by the system and places the phone into BFU (Before First Unlock) mode. Your phone is the strongest against physical extraction when in BFU mode. This feature is highly recommended, but please be aware you will not receive notifications until you unlock the device. So set this to a reasonable time. You can enable this feature by navigating to your system Settings > Security > Auto restart

ChatMail on Renati Passes Independent Forensic Testing

An independent digital forensic analysis of ChatMail on Renati OS was conducted Before First Unlock and After First Unlock, proving ChatMail on Renati is resilient to data breaches.

The purpose of this independent forensic report is to provide our customers with verifiable assurance that the technology offered is sound and technologically capable of withstanding the latest in physical extraction techniques using both proprietary exploits as well as commercially available forensic tools.

Results

  1. Unlock Device
    1. No commercially available tool, software or exploit was able to unlock the device in BFU state.
    2. No commercially available tool, software or exploit was able to unlock the device in AFU state.
  2. Data Extraction
    1. No commercially available tool, software or exploit was able to extract any data from the device in a locked state.
    2. Using the provided password in an unlocked state, the device still proved to be extremely difficult to obtain an extraction. Only system files and carrier-identifying data were able to be extracted from the device using the password that was provided to us.
    3. No user-generated data was able to be extracted.
  3. Application Data
    1. No user-generated data specifically targeting ChatMail was readable.

ChatMail 2.0 Launches, with Encrypted Calling, Tamper Protection and More Languages

The enhanced privacy of ChatMail calling combines end-to-end encryption with manual verification to prevent Man-in-the-Middle attacks.

Authenticated Verifications

As part of the identity verification process, callers are presented with a security code, which is verbally confirmed to ensure the call has not been intercepted. When making an anonymous group call, only the name of the host is shown when the three-way call is merged. The other users can speak to each other but cannot see their respective ChatMail usernames.

Technology

Call encryption and key exchange is handled by the Zimmermann Real-time Transport Protocol while Secure RTP keeps ChatMail calling private. Call traffic is configured for the phones Statistical Analysis Software with Transport Layer Security. This keeps calls and messages private and secure by removing them from the public internet.

ChatMail Secure Encrypted Calling uses TLS 1.2 Elliptic Curve Diffie-Hellman Ephemeral with X25519 SRTP + ZRTP Supported Algorithms:

  • Hash: SHA-384
  • Cipher: AES-256
  • SAS Rendering: B256(PGP word list)
  • Auth Tag: HS80
  • Key Agreement: X25519

Settings for encrypted calling can be customized, allowing users to disable calling or only allow calling while on Wi-Fi. There’s also an optional new ChatMail custom ringtone for incoming calls.

Other Upgrades

  • Authentication and tamper detection
  • Improved picture privacy
  • Addition of five new language translations, bringing the total number available to 13
  • Notebook advances now let users save up to six messages and one picture simultaneously

ChatMail 1.0 launches, self-hosting Blackberry® UEM

ChatMail® offers unparalleled mobile protection, securing your digital identity and communications with fortified Android devices, advanced end-to-end encryption, and private server hosting.

ChatMail’s multi-layer integrated encryption safeguards messages, group chats, and notes.

Android For Work (AFW) powered by BlackBerry® Unified Endpoint Management (UEM). UEM allows our partners to secure publicly available off-the-shelf devices. For extra security, we do not run the virtual server instance of UEM on their cloud. We run our own self-hosted instance, in our own private data center, to prevent unauthorized access and intrusion. BlackBerry cannot push apps to a ChatMail device.

Private Play Store exclusively built for ChatMail and our native apps, where we have full control over the security, updates, and distribution process, minimizing potential risks associated with third-party app stores.

Custom device hardening for supported devices: Google Pixel line, and select Galaxy models.
