GrapheneOS

GrapheneOS is a free and open-source, Android-based mobile operating system focused on privacy and security. It enhances the Android Open Source Project with substantial improvements in sandboxing, exploit mitigations, and permission models, delivering a hardened OS compatible with selected Google Pixel smartphones. Developed as a non-profit project, GrapheneOS avoids including Google Play services and instead offers a sandboxed compatibility layer for optional Play services installation. It also develops privacy-focused apps such as a hardened Chromium browser variant and a secure PDF viewer, targeting users who prioritize security and privacy on mobile devices.
