PrivacyLens

What is PrivacyLens?

Every website you visit loads dozens of invisible scripts. They track your clicks, fingerprint your browser, and share your data with companies you have never heard of. Cookie banners tell you nothing useful.

PrivacyLens scans every page in real time and shows you exactly what is happening behind the scenes. Which companies are tracking you, what techniques they use, and whether cookies are dropped before you even consent.

Features

• Third-party script detection - Identifies tracking scripts from Meta, Google, TikTok, and hundreds of other data collectors.
• Cookie analysis and classification - Breaks down every cookie by purpose: analytics, advertising, functional, or unknown.
• Fingerprinting detection - Flags canvas fingerprinting, WebRTC leaks, font enumeration, and other browser identification techniques.
• Network tracking domain mapping - Maps outbound requests to their parent companies and data brokers.
• Automatic purpose classification - Categorizes each tracker by what it does: retargeting, analytics, session replay, A/B testing.
• Pre-consent cookie detection - Detects cookies set before you interact with any consent banner. A GDPR violation in plain sight.
