What it checks

Check	What	Impact
Ad trackers	Google Ads, Facebook Pixel, Criteo, etc.	-8 per tracker
Fingerprinting	FingerprintJS, canvas, WebGL, audio	-10 per script

Limitations

• Static HTML analysis only — doesn't execute JavaScript (use a browser extension for full JS tracking)
• Cookie detection is first-party response only — doesn't capture third-party cookies set by scripts
• Scores are relative, not absolute — useful for comparing sites, not as legal compliance
