An operating system that respects your rights to privacy, security, and freedom, by design.

PureOS, with a clean user interface featuring GNOME, offering easy access to applications, documents, and media. A beautiful operating system designed with your privacy, security, and freedom in mind, all while retaining simplicity.

PureOS is a derivative of Debian GNU/Linux main, with added emphasis on privacy protection, where we have preinstalled the best privacy-protecting software applications and allow you to easily encrypt your hard drive.

PureOS takes the guesswork out of protecting your privacy and helps you surf the web safely, without being tracked by advertisers or marketers. It comes with the best Free/Libre and Open Source privacy and security software and apps for privacy “out of the box”—including the Tor browser, the Duck Duck Go search engine, EFF Privacy Badger, and HTTPS: Everywhere bundled into our official web browser, PureBrowser.

PureOS is entirely free/libre and open-source, meaning you don’t have to trust our word that it respects and protects you—it is independently verifiable by security experts and software developers around the world. Should you find ways to improve its security further, please get in touch with us!

The OS, apps and updates are free—forever.

We believe that when you own a computer, you own it. You will not have to pay monthly charges or recurring payments to keep your software up to date. All the software is included for free when you use PureOS. There are no hidden agendas or “gotchas” like with some other platforms out there. There are no forced upgrades, either.

Oh, and you can download it for free, even if you don’t own one of our products. We’re looking forward to having you as part of our community of users.
