Website Cookie Scanner

Every time you visit a website, it can store small pieces of data on your browser called cookies. These cookies serve a wide range of purposes, from remembering your login session and language preferences to tracking your behavior across the entire internet for targeted advertising.

Not all cookies are created equal. Necessary cookies are essential for a website to function correctly — they handle authentication, shopping carts, security tokens, and user preferences. Without them, most modern websites would not work properly. These cookies are generally considered privacy-friendly because they only serve the site you are visiting.

Analytics cookies, on the other hand, are used by services like Google Analytics, Mixpanel, and Hotjar to measure how visitors interact with a website. While they help website owners improve their services, they also collect data about your browsing patterns, session duration, pages visited, and device information. This data can be aggregated to create detailed behavioral profiles.

Marketing and advertising cookies are the most invasive category. Set by third-party ad networks and social media platforms, these cookies follow you across websites to build a comprehensive profile of your interests, demographics, and purchasing intent. Companies like Facebook, Google, and dozens of ad tech intermediaries use these cookies to serve you targeted advertisements.

Regulations like the GDPR in Europe and the CCPA in California have forced websites to be more transparent about their cookie usage, requiring explicit consent before setting non-essential cookies. However, enforcement varies widely, and many websites still deploy extensive tracking by default. Using tools like this cookie scanner helps you understand what a website is doing before you decide to accept its cookies.
