Operating Systems

Even your own computer could be compromising your privacy. Discover our recommended OS choices for all the devices you use.

Introductory Operating Systems

Fedora Workstation Linux

Fedora Workstation logo Fedora is a Linux distribution developed by the Fedora Project and sponsored by Red Hat. Fedora Workstation is a secure, reliable, and user-friendly edition developed for desktops and laptops. Fedora by default comes with the GNOME desktop environment, other desktop environments are also available.

Ubuntu Linux

Ubuntu logo Ubuntu is a Linux distribution developed by Canonical Ltd. Ubuntu is a reliable distribution that is user-friendly and can be run on desktops, servers, and IoT devices. Ubuntu uses GNOME as the default desktop environment, while other desktop environments are also available.

Advanced Operating Systems

Alpine Linux Linux

Alpine Linux logo Alpine Linux is a very minimal distribution designed to be secure and very resource efficient. Alpine Linux can run from RAM, and merge configuration files into the system on boot using Alpine local backup. Alpine Linux is often used on servers and in Linux containers.

Arch Linux Linux

Arch Linux logo A simple, lightweight Linux distribution. It is composed predominantly of free and open-source software, and supports community involvement. Reproducible builds

Debian Linux

Debian logo Debian is a Unix-like computer operating system and a Linux distribution that is composed entirely of free and open-source software, most of which is under the GNU General Public License, and packaged by a group of individuals known as the Debian project. Reproducible builds

NixOS Linux

NixOS logo NixOS is a Linux distribution with a unique approach to package and configuration management. Built on top of the Nix package manager, it is completely declarative, makes upgrading systems reliable, and has many other advantages. Reproducible builds

Qubes OS Xen

Qubes OS logo Qubes is an open-source operating system designed to provide strong security for desktop computing. Qubes is based on Xen, the X Window System, and Linux, and can run most Linux applications and utilize most of the Linux drivers.


Tor-Focused Distributions

Tails Linux

Tails logo Tails is a live operating system that can boot on almost any computer from a DVD, USB stick, or SD card you control. It aims at preserving privacy and anonymity, and circumventing censorship by forcing Internet connections through the Tor network; leaving no trace on the computer; and using state-of-the-art cryptographic tools to encrypt files, emails, and instant messages.

Whonix Linux

Whonix logo A Debian-based security-focused Linux distribution. It aims to provide privacy, security and anonymity on the internet. The operating system consists of two virtual machines, a "Workstation" and a Tor "Gateway". All communication are forced through the Tor network to accomplish this. Whonix is best used in conjunction with Qubes.

Mobile Operating Systems

GrapheneOS AOSP

GrapheneOS logo GrapheneOS is a free and open-source security and privacy-focused mobile operating system built on top of the Android Open Source Project. It expands upon android security by providing a hardened memory allocator, network and sensors permission, sandboxed Play Services support, and various other security features. Using GrapheneOS is recommended if you want the utmost security for your device. Currently, only Pixel phones are supported.


CalyxOS logo CalyxOS is a custom ROM based on the Android Open Source Project, with support for Google Pixel devices and the Xiaomi Mi A2. It aims to be secure and private by default, and includes a number of good choices for default applications. Some of its features include optional MicroG support and a built-in firewall. It should be noted that CalyxOS lacks a lot of the security hardening that GrapheneOS has, such as a hardened memory allocator, hardened webview, more secure spawning system, and so on.


DivestOS logo DivestOS is a soft-fork of LineageOS with signed builds, automated kernel vulnerability (CVE) patching, fewer proprietary blobs, along with bundled F-Droid and UnifedNlp. Not all of its supported devices support verified boot, and DivestOS does not handle firmware updates well currently. For Pixel devices, we still recommend using GrapheneOS or CalyxOS. For other supported devices, DivestOS is a good option.

Android Privacy Add-ons


Control your traffic with NetGuard

NetGuard provides simple and advanced methods to block certain apps from accessing the internet, without requiring root privileges. Applications and addresses can be individually allowed or denied access to your Wi-Fi and/or mobile connections, allowing you to control exactly which apps are able to phone home or not.

The main components are the Linux kernel, util-linux, uClibc and BusyBox. All components have been optimized for size, to be small enough for fitting into the limited storage and memory available in home routers.

pfSense BSD

pfSense logo pfSense is an open source firewall/router computer software distribution based on FreeBSD. It is installed on a computer to make a dedicated firewall/router for a network and is noted for its reliability and offering features often only found in expensive commercial firewalls. pfSense is commonly deployed as a perimeter firewall, router, wireless access point, DHCP server, DNS server, and as a VPN endpoint.
