Find out more about cookies and what you can do
A cookie is simply a technology to remember something about you.
Without cookies, a website is like a goldfish that loses its memory every time you visit a new page. Once you visit a new page, you don't remember who you are.
Now this can be a good thing and a bad thing. Without memory, a website cannot do many things. It won't let you log in, because you forget who you are. It cannot allow you to buy anything, because it forgets what you are buying.
Cookies are not automatically good or bad, but it is worth understanding what you can do about them.
You can turn them off completely, but you should know that many Web sites simply won't work.
A better option would be to disable third-party cookies, which will prevent most websites from sharing information about you. Some browsers, like Safari, do this automatically.
And finally, you can take a closer look at any website that concerns you. Most websites have policies that explain what they do.
