How we Transform Regular Google Pixel Phones into Your Secure, Private Cellphone

We only use official releases of the mobile operating system GrapheneOS. GrapheneOS is a privacy and security focused mobile operating system built on top of the open source Android project. It’s developed as a non-profit, open source project.

GrapheneOS improves the privacy and security of the operating system from the bottom up. It deploys technologies to mitigate whole classes of vulnerabilities and make exploiting the most common sources of vulnerabilities substantially more difficult. It improves the security of both the operating system and the apps running on it.

The following is a plain-English list of the features that we feel are the most important and the easiest for the layperson to understand. For the full (and somewhat technical list, see the GrapheneOS Feature List.

• A stronger app sandbox: This means that apps run in an isolated location on your phone. They don’t share information with other apps or communicate outside your phone without approved permissions.
• Vanadium – your default and privacy-respecting browser. Vanadium (custom-built by the developers of GrapheneOS) is also a hardened WebView. What is a WebView? The WebView is what most other apps use to handle web content, so this secures your browsing experience on Rogue Phone and also secures many of the apps you’ll use day-to-day.
• Hardware-based security verification and monitoring – this is an auditor service that ensures your operating system has never been tampered with our added to – not by us, not by anyone.
• Seamless automatic update system that just works and stays out of the way in the background without disrupting device usage.
• Minimal bundled apps and services. Only essential apps are integrated into the OS. GrapheneOS doesn’t make partnerships with apps and services to bundle them into the OS. Rogue Phone’s approach will be recommending certain apps during the initial setup, not hard-wiring them into the OS.
• No Google apps and services built-in. Building privileged support for Google services into the OS isn’t something GrapheneOS is going to be doing.
