# LinkSanitizer — Chrome Extension

A lightweight, high-performance Manifest V3 Chrome extension that automatically strips tracking parameters from URLs **before** the page loads — protecting your privacy silently in the background.

Designed with a sleek, minimalist dark UI, LinkSanitizer blocks analytics, social media, and advertising trackers in real-time, keeping your browsing fast and clean.

## ✨ Key Features

* **Real-Time Sanitization:** Instantly intercepts and purges URLs before the browser requests the page.
* **Global Counter & Icon Badge:** Live activation counter showing exactly how many tracking parameters have been stripped.
* **User-Customizable Allowlist:** Easily whitelist specific domains (e.g., `amazon.it`, `ebay.it`) directly from the popup if you need tracking active for specific sites.
* **Master On/Off Toggle:** Pause and resume the extension globally with a single click, featuring a responsive color-coded visual indicator (Green for Active, Red for Paused).
* **100% Local & Private:** No data is ever sent to external servers. All settings and counts are kept strictly on your machine via `chrome.storage.local`.
