Why install NPLD?
Because your browser constantly communicates with multiple services, websites, and trackers. Many times, sensitive tokens or IDs are unintentionally exposed. NPLD makes these risks visible in real-time and helps you take action before it’s too late.
Whether you’re a developer testing web apps, a researcher analyzing leaks, or simply a user who values privacy, NPLD is a powerful tool for your browser security toolkit.
