One major risk associated with accumulated cookies is third-party tracking. Websites often share stored cookies with advertisers and other third parties, who can use this data to build detailed profiles of your online behavior. This information can then be used to serve you targeted ads, potentially bombarding you with unwanted solicitations. Moreover, stored cookies can sometimes be exploited by hackers to gain unauthorized access to your accounts and personal information. Additionally, accumulated cookies can slow down your device, leading to inefficient performance and a diminished user experience.
