Cookie & Tracker Exposer — Website Privacy Audit
Modern websites embed extensive tracking infrastructure: analytics platforms, advertising pixels, session replay tools, and fingerprinting scripts. This tool provides a comprehensive inventory of everything a website deploys to monitor your activity, scored on a privacy risk scale from 0 to 100.
What Gets Scanned
The bookmarklet inventories all cookies currently set, localStorage and sessionStorage contents, every loaded script (marking third-party sources), known tracking platform patterns across 20+ common trackers, third-party domain connections, and browser fingerprinting indicators including Canvas, WebGL, AudioContext, and hardware APIs.
- Third-Party Scripts
- Scripts loaded from domains other than the site you are visiting. These are the primary mechanism for cross-site tracking.
- Browser Fingerprinting
- Techniques that use browser and device characteristics to create a unique identifier without cookies. Canvas rendering, WebGL parameters, and hardware specs are commonly used signals.
🍪 Cookie & Tracker Exposer — FAQ
Does this detect all trackers?
It detects 20+ major tracking platforms by pattern matching against script URLs and page HTML. Custom or obfuscated trackers may not be detected. The third-party domain list provides additional coverage.
Can I use this on any website?
Yes — the bookmarklet runs on any website. It reads cookies, storage, and DOM elements that are accessible in your browser session.
Does it block trackers?
No — this is an audit tool, not a blocker. It identifies what is tracking you. For blocking, use tools like uBlock Origin or Privacy Badger.
Why does the cookie value show as truncated?
Cookie values are truncated to 100 characters in the display for readability and to reduce data transfer size. The full values remain in your browser.
Is localStorage data sensitive?
It can be. Some sites store authentication tokens, user preferences, or tracking identifiers in localStorage. Unlike cookies, localStorage data does not expire automatically and persists until explicitly cleared.
