What information does a cookie store?
Cookies don’t usually store information about you, like credit card numbers or banking information, photos, your ID or personal information, etc. The data stored are technical, personal preferences, content personalization, etc.
The web server doesn’t relate you as a person or even your web browser. Actually, if you are frequently on Internet Explorer and try to navigate on the same web with Firefox or Chrome, you will see that the web doesn’t realize that you are the same person because it is actually associating with the web browser, not the person.
What types of cookies are there?
Technical cookies: they’re the basic ones, and they let you know when a human or an automated application is navigating, when a registered or unregistered user navigates and basic tasks for any webpage’s well function.

Publicity cookies: they show advertisements depending on your navigation, your country of providence, language, etc.

Internal cookies are those that are generated by the web page you are visiting in that moment and third party cookies are those generated by services or external suppliers such as Facebook, Twitter, Google, etc.
What happens if I deactivate the cookies?
To understand the reach that deactivating cookies can have, here are a few examples:

You won’t be able to access to the personal area of that web, like for example My account, or My profile or My orders.
Online stores: it will not be possible to make online purchases; they will have to be over the phone or going to the store in person, if it has one.
