Cookie Analyzer: Inspect Site Privacy Practices
Cookies are small pieces of data websites store in your browser to identify you, remember preferences, and track your activity. Our analyzer breaks down all cookies on a site and classifies them by purpose (session, tracking, marketing, third-party).
We show you the domain, expiration, SameSite policy, Secure/HttpOnly flags, and estimated purpose of each cookie. Essential for auditing GDPR/CCPA compliance or understanding how a site tracks its visitors.
The scan runs from your browser without sending data to servers. You can inspect any URL and get an immediate report of its cookie ecosystem.

Frequently Asked Questions
First-party cookies are set by the site you visit (e.g., session, preferences). Third-party ones come from external domains (usually trackers like Google Analytics, Facebook Pixel) and are the main GDPR concern.
Cookies without SameSite policy can be sent in cross-site requests, exposing you to CSRF. Modern browsers default to SameSite=Lax, but old cookies may not have this flag.
Blocking session cookies breaks logins on most sites. What you can safely do is block third-party trackers with extensions like uBlock Origin or Privacy Badger.
