Cookies are generally small text files stored by your web browser when you use websites. The cookies which the website uses do not identify individual users, and are widely used in order to make its website work, or work more efficiently, by tracking users during a “session” while they are visiting the web site, or being able to identify them when they return for another “session.”
Again, cookies are not used to identify specific persons - only to be able to track a specific user of the website, sometimes when they leave the website and come back, to make sure the website works well for that user and for other users.
