What information does a cookie store?

Cookies usually do not store sensitive information about you, such as credit cards or bank details, photographs, your ID or personal information, etc. The data they store is of a technical nature, personal preferences, personalization of contents, etc.

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