cookie可能是四种类型之一。一种是“必要的”。这些对你浏览一个网站和使用它的功能是必要的,例如向在线购物车添加商品。第二种类型是“表现”。它们收集关于你如何使用网站的信息。收集的信息包括,例如,使用的互联网浏览器和操作系统,以前访问过的网站域名,访问次数,平均访问时长,以及浏览的页面。他们收集的信息不会识别您的个人身份;它保持聚合和匿名。性能cookie帮助我们改善我们网站的用户友好性,并增强您的体验。第三种类型是“功能性”。 Functional cookies remember choices you have made related to our website (such as your username, your language, your region, and your preferences as to user-customizable aspects of a web page’s appearance, such as text size and fonts) in order to provide enhanced, more personal features. The information these cookies collect may be anonymized, and they cannot track your browsing activity on other websites. The fourth type is “targeted advertising.” These cookies track your browsing activities and enable advertisers to send to you (that is, to pop-up on your screen) advertising related to things in which your browsing history indicates that you likely have an interest. They can also track and control the number of times you see an ad and so can measure the effectiveness of advertising campaigns. They are usually placed by advertising networks with the website operator’s permission. They remember that you have visited a website and this information is shared with advertisers. As an example, if you visit a page on our website related to one of our products, you may begin to see pop-up notices related to that or other products in your future Internet browsing.
