GrapheneOS is an open-source, Android-based operating system built specifically for maximum privacy and security. It runs exclusively on Google Pixel hardware, because only these devices support the full verified boot process using your own signing keys.
What makes GrapheneOS different from stock Android?
- No Google Play Services, no Google tracking running in the background
- A hardened memory allocator that prevents many classes of exploits from the outset
- Its own, far stricter permission management — for example, network access and sensors can be blocked individually for each app
- Regular security updates, usually released the same day
- Verified boot stays fully intact — at every startup the device checks whether the system software is unchanged
Is GrapheneOS right for everyone?
In everyday use, GrapheneOS is just as usable as a regular Android smartphone: apps from the Play Store can be installed through the optional, isolated "Sandboxed Google Play" compatibility layer, without Google gaining system-wide access in the process. Those who can do entirely without certain Google services benefit most from the added isolation.
At SaferPhone, GrapheneOS comes pre-installed and configured — you don't have to flash or set up anything yourself.
