StealthHound

StealthHound is a Chrome extension that delivers comprehensive browser fingerprinting protection and real-time tracker blocking. It is designed for privacy-conscious users, developers, and anyone who wants to take control of their online privacy. The extension's core value lies in exposing hidden tracking techniques that most websites use, such as canvas fingerprinting, hardware probing, and silent data collection, and then automatically blocking them while providing full visibility into what each site is doing. By making invisible tracking visible, StealthHound empowers users to make informed decisions about their browsing. Unlike traditional ad blockers that only remove ads, StealthHound specifically targets advanced tracking methods that persist even when cookies are blocked. It offers a privacy-first approach with zero data collection, ensuring your information never leaves your device.

The concrete problem that StealthHound solves is the pervasive, invisible tracking that occurs on the modern web. Most websites track users without explicit consent, using browser fingerprinting, hidden scripts, and behavioral analysis to create a unique device identifier. This tracking happens even when cookies are blocked, making it difficult to maintain privacy. The consequence is that users are profiled across sites without their knowledge, leading to targeted advertising, price discrimination, and data breaches. StealthHound makes this hidden tracking visible by providing real-time risk scores and live alerts. It gives users full control over their data, allowing them to see exactly which tracking attempts are made and block them automatically. This transparency is crucial for anyone who values their privacy and wants to avoid being silently profiled.

The first major feature group is the Real-Time Risk Score. This feature analyzes every website you visit and assigns a risk score based on the tracking activity it detects. It works by evaluating scripts, canvas operations, and API calls that are typical of fingerprinting and data collection. The usefulness of this feature is that it provides an instant, at-a-glance assessment of a site's trustworthiness. Users can decide to stay or leave a site based on the score, without needing to understand the technical details. The risk score is dynamically updated as the page loads, reflecting the exact tracking behavior of that website. This empowers users to make proactive privacy decisions while browsing.

The second major feature group comprises Live Tracking Alerts and Automatic Tracker Blocking. Live Tracking Alerts send notifications whenever a website attempts fingerprinting, hidden scripts, or other covert tracking techniques. Users see exactly what is being blocked in real time, providing complete transparency. Automatic Tracker Blocking works in the background to stop invasive tracking without requiring any user intervention. It blocks canvas fingerprinting, hardware probing, API tracking, and other methods as soon as they are detected. The combination of alerts and automatic blocking means users are both informed and protected. This hands-off approach is ideal for those who want strong privacy without constant manual configuration.
