What Are Cookies and How Do They Track You?

Cookies are small pieces of data stored by your web browser when you visit a website. They can hold various types of information, such as login status, user preferences, and tracking data. By saving this information, cookies enable websites to remember users across sessions, improving the browsing experience.

There are two main types of cookies: session cookies and persistent cookies. Session cookies are temporary and expire when you close your browser, while persistent cookies remain on your device for a set duration or until deleted. Websites use both types to tailor user experiences and enhance functionality.

Cookies track you by storing information about your interactions with a website. For example, when you visit an online store, cookies can keep track of the items you add to your cart, your login details, and your browsing history. This data helps websites present more personalized content, such as recommendations based on past behavior.

Tracking cookies, specifically, are used by advertisers to follow your activity across different websites. This capability allows them to build a profile of your interests and deliver targeted ads. While this can make advertising more relevant, it also raises privacy concerns among users.

Most web browsers allow users to manage their cookie preferences. You can choose to block all cookies, allow only certain types, or regularly clear them. Additionally, many websites now provide clear notices about their use of cookies and ask for consent before deploying them, in compliance with regulations such as the GDPR.

In conclusion, cookies play a significant role in enhancing your web experience, but they also introduce privacy challenges. Being informed about how cookies work and how they track your online behavior can help you make better decisions regarding your online privacy.
