Your operating system is the foundation of your digital privacy. It controls every aspect of your device's operation, from network connections to file access to application permissions. Unfortunately, mainstream operating systems like Windows, macOS, and standard Android are designed with data collection and user profiling as core features.
Privacy-focused operating systems prioritize user control, minimize data collection, provide transparent security practices, and give you the tools to protect your digital life. Many are open-source, allowing independent security audits and community-driven development.
Here's a comprehensive guide to privacy-focused operating systems for both computers and mobile devices.

Choose an operating system that matches your technical skills, security needs, and privacy requirements. Start with manageable improvements and gradually enhance your privacy and security as you gain experience and confidence.
Your operating system is the foundation of your digital privacy. Invest the time to choose and configure one that respects your rights and protects your data rather than exploiting it for profit.
