What information does a cookie store?

Cookies do not usually store sensitive information about you, such as credit card or bank data, photos, your ID, or personal information, etc. The data they keep is of a technical nature, personal preferences, content personalization, etc.

The web server does not associate you as a person but your web browser. In fact, if you usually browse with Internet Explorer and try to browse the same web with Firefox or Chrome, you will see that the web does not realize that you are the same person because it is actually associating the browser, not the person.
