Security and Privacy
PureOS helps you surf the web safely, without being tracked by advertisers or marketers.
Privacy, security, and freedom by design
PureOS comes with the best free/libre privacy and security software and apps for privacy “out of the box” — including the Duck Duck Go search engine and HTTPS: Everywhere bundled into our official web browser, PureBrowser.
PureOS allows you to easily encrypt your whole operating system and data, with your own encryption keys, whether you download and install it yourself or receive it preloaded.
PureOS is entirely free/libre software, meaning that you can freely use it for any purpose, study its source code, share it and even modify it.
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!
