DivestOS
Android-based mobile operating system

DivestOS was an open source, Android operating system. It was a soft fork of LineageOS that aimed to increase security and privacy with support for end-of-life devices. It removed many proprietary blobs and pre-installed open source apps.

DivestOS builds were signed with release-keys so bootloaders may be re-locked on supported devices. An automated CVE patcher was used to patch the kernels against many known vulnerabilities.

DivestOS included few default applications. F-Droid was included, as well as Hypatia, a "real-time malware scanner" and Carrion, a robocall blocker.
