Open Source Privacy Tools
Privacy is the ability to control how personal information is collected, used, stored, and shared. Privacy-focused technology helps reduce tracking, limit unnecessary data collection, protect communications and files, and keep sensitive activity out of third-party services. It can also give people more choice over where their data lives and how long it is retained, whether they are browsing, collaborating, or using digital services offline.
Open source privacy tools include browsers, content blockers, encrypted communication and collaboration software, local-first apps, and utilities for securing data. When choosing one, consider its security model, maturity, maintenance activity, license, platform requirements, and compatibility with services you already use. Check whether its privacy claims match how it handles data in practice. These tools are useful to individuals, organizations, and developers seeking greater transparency and control over personal or sensitive information.
