This means that users do not need to re-configure their preferences on each visit. Without cookies, a website treats you as a new visitor each time you load a web page. For example, if you log in to a website and switch to another web page, the website will no longer recognize you and you will be logged out. Huawei will not use cookies for any purposes not stated in this Statement. You can manage or delete cookies based on your preferences. For details, visit AboutCookies.org.
