What are cookies on the computer?

Cookies are small text files, that the websites you visit create and store in your browser.  Cookies contain data of user logins, passwords, preferences, statistics and other information. Each time you visit an appropriate website, your browser sends to it cookies for identifying you as a user. As a result, you have a smoother passage when you visit the page the next time – you don’t need to enter a login and password each time.

Generally, cookies are used for:

  • Authenticating the user;
  • Storing user settings and personal preferences;
  • Monitoring the status of the user’s access session;
  • Conducting various user statistics.

Browsers collect users statistics for many purposes: to show you ads that are relevant to you, to calculate the pagerank of websites, to protect your data and more. You may have noticed cookie policy popups on some websites, which ask you to agree to collecting cookies from your computer or device. Why does this message appear? The reason is that the Cookie Privacy Law of some countries, such as the UK and EU, requires that websites provide information to visitors about collecting cookie data. The cookie privacy law requires the disclosure of information about processing personal data under various data subjects.

Cookies are simple text data and they cannot perform any action on their own. A cookie cannot therefore be a virus or spyware. Most modern browsers allow users to choose to accept cookies or not; however, declining them makes it impossible to work with some websites.

Why clear cookies on Mac?

Despite their usefulness, cookies have some disadvantages, among which are:

  • Anyone who has access to your computer can login to forums and websites under your name.
  • A large number of cookies take up disk space.
  • It is possible to trace the history of your visits, which is undesirable from the privacy point of view.
