Key Features

DivestOS is a vastly diverged unofficial soft fork of LineageOS.


Security

Monthly Updates

All supported devices receive monthly security updates. Select devices support incremental updates for smaller update downloads. DivestOS however cannot and does not include all ASB patches as detailed here.

Automated Kernel CVE Patching

We've developed an automated patch checker along with an extensive database of fixes for over 3,150 Linux kernel security issues. These are automatically applied where possible to all devices.

Bootloader Relocking

Bootloader relocking is restored and has been tested working on 23 devices and is available for 26 more. Verified boot is also restored on 36 of those devices and is enforcing once locked.

System WebView

The Mulch hardened Chromium WebView is included with features like control-flow integrity and network state partitioning enabled. Furthermore Mulch is updated independently of the system image via an F-Droid repository for rapid security updates.


Privacy

Powerful Tracker Blocker

A custom wildcard-optimized hosts file created by analyzing over 180 million domains is included that blocks over 900,000 advertising and tracking servers.

Privacy Oriented Browser

Mull is a browser based on Mozilla technology that is hardened against fingerprinting techniques thanks to the Tor uplift project and arkenfox-user.js project.


Freedom

FOSS Focused

DivestOS ensures to uphold the four freedoms of free software through and through. We also encourage and help other projects in this space to re-use our work.

Deblobbed

Over 700 proprietary blobs are removed during build time. Removal of these proprietary blobs increase security by reducing attack surface and increase privacy by removing untrusted code.

F-Droid Included

F-Droid is an app catalog that specializes in delivery of FOSS apps. For the most part all apps available through F-Droid respect your privacy and device.


Extras

Free Space Eraser

Extirpater is the first free space eraser for Android. It helps prevent deleted files from being recovered. Perfect for migrating from an unencrypted install or before selling your device.

Malware Scanner

We created Hypatia, the first ever open source real-time malware scanner for Android. Backed by the standard and independent ClamAV signatures, it can detect over 450,000 Android-related malware signatures.
