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]


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.[5]

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


On June 11th, 2018, Daniel Micay, the main developer of CopperheadOS and 50% stakeholder, was cut off from his employer,[6] with an order to turn over access to the subreddit and his Twitter account. On his Twitter, he mentioned that his employer was attempting to seize his personal GPG key.[7][user-generated source]
