How long cookies are stored on your PC

It depends on the type of cookies. There are two different types of computer cookies:

Session cookies

Session cookies (“non-persistent cookie”) are cookies that only exist as long as your session on the web site lasts and expires as soon as you leave the website. The primary purpose of session cookies is to help with navigation. Such as by indicating whether or not you’ve already visited a particular page. Retaining information about your preferences once you’ve visited a page. So session cookies are used to facilitate your activities within that site.

Persistent cookies

The second type of cookies is “persistent cookies”. Persistent cookies are stored on your computer in order to recognize user and retain his/her personal preferences when he/she returns to a website. E.g. because of persistent cookies a website remembers your name and password on protected login pages, your email address appears by default when you open your Yahoo! or Hotmail email account or your personalized home page appears when you visit your favorite online merchant. Persistent cookies exist beyond the life of your Internet session and may live for months or years. In most browsers, you can adjust the length of time that persistent cookies are stored. If anyone has access to your computer, he or she may use information stored in persistent cookies to gather personal information about you.
