GrapheneOS

Maximum privacy OS for Pixel

Overview

GrapheneOS optimizes Android for security and privacy on Google Pixel hardware with hardened kernel, memory tagging, and strengthened permissions beyond stock AOSP.

Google Play Services are not bundled. You may install Play Store inside a sandbox isolated from normal apps when compatibility demands it.

Highly rated in security research—chosen by journalists, activists, and privacy-conscious users worldwide.
