A cookie is a small amount of data, which often includes a unique identifier that is sent to your computer or mobile phone browser from a website’s computer and is stored on your computer’s or mobile phone’s hard drive. Each website can send its own cookie to your browser if your browser’s preferences allow it, which the site can then access when you visit it again to track online traffic flows, for example. A website cannot access cookies sent by other websites.
