Cookies are small data files stored on your device by websites to retain information specific to your browsing. Developed to address the stateless nature of web pages, cookies act as a form of memory, enabling functionalities like staying logged in across pages and preserving preferences for future visits. Beyond enhancing user experience, cookies also facilitate behavioral advertising by tracking pages visited across sites to tailor ads to your interests. While nearly all websites employ cookies to provide personalized and interactive services, they can also influence your browsing in unexpected ways, sometimes benefiting others without your direct knowledge. Understanding cookies requires trust in the website's openness about their usage, as their effects can be both helpful and intrusive.
