About
GrapheneOS is a privacy and security-focused mobile operating system with Android app compatibility. Developed as a non-profit open source project, it aims to provide substantial improvements to sandboxing, exploit mitigations, and the permission model, enhancing both OS and app security without compromising user experience. Founded in 2014 and formerly known as CopperheadOS, GrapheneOS strives to mitigate whole classes of vulnerabilities and fortify security boundaries within the OS and its applications. GrapheneOS also contributes to the Android Open Source Project (AOSP), Linux, and other projects to improve privacy and security for billions of users. It will never include Google Play services or another implementation of Google services like microG, but users can install them as fully sandboxed apps via the sandboxed Google Play compatibility layer.
