CopperheadOS is a source-available operating system for smartphones and tablet computers, based on the Android mobile platform. It is based on the official releases of the Android Open Source Project by Google, with added privacy and security features.[2][3][4]

The manufacturer sells high-end smartphones (currently Pixel 2 and Pixel 2 XL) that have CopperheadOS preinstalled and ready to use.[5]


The manufacturer states in the CopperheadOS documentation:[6]

There aren’t analytics / telemetry in CopperheadOS.

The manufacturer also provides documentation and recommendations on installing privacy-friendly applications.

The OS-wide privacy features are found across many levels and areas of the OS, e.g.:

  • Per-application network access can be managed in CopperheadOS settings.
  • Default DNS set to privacy-friendly provider
  • Ability to choose an offline calendar instead of online services
  • Option to encrypt SMS

A list of the connections made by the OS itself is given in the documentation. [6]


In August 2016, CopperheadOS announced future versions of the operating system, based on Android Nougat 7.x, would be released under a no-commercial-usage license until more funding could be acquired. Non-commercial modification and redistribution are still permitted.[7]

In March 2017, support for Pixel and Pixel XL devices was launched, with an offer to buy these devices with CopperheadOS preinstalled.
