GrapheneOS

GrapheneOS is an open source privacy and security focused mobile OS with Android app compatibility. It is a privacy / security research and engineering project that has been under way for over 5 years. It recently became rebranded as GrapheneOS and is taking a different direction based on obtaining funding for the research and development work as a non-profit open source project rather than being a company. The reborn project is still in a very early stage and lots of the past work on privacy and security has not yet been restored for the new incarnation of the OS. The grapheneos.org site is very new and is currently being put together. It will have lots of additional documentation and tutorials in the future along with coverage of various software, firmware and hardware privacy/security topics. GrapheneOS is being supported with funding and developers from various companies and other organizations interested in contributing to this shared base for a feature rich private and secure mobile operating system able to run many existing applications. It will take more time to organize and deploy these resources in order for the project to have a strong development team with proper infrastructure behind it.
