What Cookies and Similar Technologies Are
Cookies are small files that a website stores in your browser to recognize it from one page to the next, or from one visit to the next. Similar technologies do the same job by other means, such as the browser’s local storage.
First-party cookies are stored under this site’s domain, even when a tool from another company sets them; third-party cookies are stored under that company’s domain, such as Google or Microsoft. Each section gives the name, who sets it, what it is for and how long it lasts.
