This repository is a curated collection of Markdown files providing detailed, step-by-step instructions for configuring privacy and security settings across a wide range of software, operating systems, and online services. It covers desktop and mobile browsers (Brave, Firefox, Chrome, Edge, Vivaldi), operating systems (Windows 10/11, Android versions, macOS Sequoia), messaging apps (Signal, WhatsApp, Telegram), social media (Facebook, Instagram, Reddit, Twitter), and many other tools. The content is organized alphabetically, with each file containing screenshots (referenced but not included in the repo), notes, and tips. There is no executable code or build system; the repository is purely documentation. It serves as a reference guide for users seeking to minimize data collection and tracking. The project is actively maintained, with frequent updates tracking changes in the latest versions of the covered software.
