CopperheadOS is a source-available operating system for smartphones and tablet computers, based on the Android mobile platform. It adds privacy and security features to the official releases of the Android Open Source Project by Google,[2][3][4] with the goal of upstreaming these back into Android, Linux and OpenBSD.[5]


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.[6]

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, then-Chief Technology Officer and 50% stakeholder in a company, announced publicly that he had been cut off from the company in an e-mail sent to him by James Donaldson,[7][8] with an order to turn over access to the subreddit and Micay's Twitter account. Mr. Donaldson, representing the company, let Micay know, that Micay would receive pay, if he signed an employment agreement. On his Twitter, Micay wrote, that Mr. Donaldson was attempting to seize Micay's personal GPG key, which was also used to secure key parts of the Copperhead Project.[9][10] Micay reportedly deleted those signing keys, which were required to release updates to CopperheadOS.[11]
