@nprofile1q... @nprofile1q... @nprofile1q... A plain Android system without modification in a fork is the Android Open Source Project. It provides a much higher level of privacy and security. LineageOS reduces privacy and security compared to that baseline but is still far more private and secure than traditional desktop Linux distributions.

Stock Pixel OS and every other OEM variant of Android are forks of AOSP just like GrapheneOS. AOSP is the reference implementation of Android and is the upstream project for it.
