While cookies are useful for customizing preferences or retaining certain personal information for repeat customers purchasing products online, they can also be intrusive when it comes to collecting demographic information or tracking your every movement on the internet. Cookies enable companies to not only track and document your surfing habits on any particular site, but also across all sites. Over time, an accurate profile can be built of your likes, dislikes, what products and services you purchase, and at what frequency you buy them.
Cookies are only as intrusive as you allow them to be. They can store only the information you volunteer; if you don’t want a site to have any of your personal information, don’t enter it.
