Guide: CalyxOS

CalyxOS is a privacy-focused mobile operating system based on the Android Open Source Project (AOSP). It is designed to be a more user-friendly alternative to GrapheneOS, while still providing a high level of privacy and security.

How it Works:

• microG: CalyxOS includes microG, a free and open-source implementation of Google Play Services. This allows users to run many apps that rely on Google services without having to install the official, privacy-invasive Google Play Services.
• Privacy by Default: CalyxOS includes a number of privacy-enhancing features by default, such as the CalyxVPN, the Datura firewall, and a number of privacy-focused apps.

Supported Devices

CalyxOS supports a wider range of devices than GrapheneOS, prioritizing models that allow for bootloader relocking.

As of mid-2025, this includes:

• Google Pixel: Pixel 4 through Pixel 8 series.
• Fairphone: Fairphone 4 and Fairphone 5.
• Motorola: Select models like the Moto G34, G42, G54.

The list changes frequently. Always check the official CalyxOS device support page for the most current list and support timeline.
