- Only the information that you provide, or the choices you make while visiting a Web site, can be stored in a cookie. For example, the site cannot determine your name or e-mail address unless you choose to enter it into a pre-existing input box.
- Allowing a Web site to create a cookie does not give that site or any other site – access to the rest of your computer.
- Cookies cannot roam around inside your computer and collect personal information.
- Only the site that created the cookie can read it.
There are two types of cookies:
- The first type, a session cookie, only stays in your computer during the time you are logged into a particular site. When you leave the site, the cookie automatically deletes itself.
- The other type, called a persistent cookie, can have an indefinite shelf life or have a predetermined expiration date built in. These types of cookies are primarily used to remember you for a specified period of time. For instance, if you sign up for membership in a particular area, or enter a program that requires you to participate over a length of time, persistent cookies are used to remember you. Another example is with web sites that offer the ability to personalize the way the page is displayed.
