What information does a cookie store?
Cookies do not usually 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, personalisation of content, 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 website with Firefox or Chrome you will see that the website does not realise that you are the same person because it is actually associating the browser, not the person.
