CalyxOS

About

CalyxOS is a free and open-source mobile operating system for Android, originating from the United States, designed with a 'Privacy by Design' philosophy to protect users from government and corporate tracking and surveillance. As a custom ROM, it offers a lightweight, ungoogled, and privacy-focused experience, ensuring no tracking and supporting features like OTA Updates, Dark Mode, and offline functionality without requiring registration. Its core product is the CalyxOS mobile OS, which replaces proprietary Google Play Services with MicroG, allowing users to run most Android applications while maintaining privacy. The platform also integrates a suite of privacy-enhancing applications such as GCam, Firewall, Onion collection, Hypatia, Calyx VPN, Riseup VPN, K-9 Mail, and DAVx. CalyxOS is highly regarded for its robust security, including the ability to lock the bootloader, and its encrypted communications. It holds a strong market position among privacy-conscious users, frequently drawing comparisons to competitors like GrapheneOS and iodé. Users praise its clean interface, comprehensive security features, and the supportive, friendly community, which also allows for feature suggestions and voting. While specific founding history, revenue, leadership, and employee count are not publicly detailed, its commitment to open-source development and user privacy is evident across its offerings and community engagement, as highlighted on its official website, calyxos.org, and social channels like Facebook and Twitter.
