What Are Cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. They are widely used by website owners to make their websites work, or to work more efficiently, as well as to provide reporting information. Cookies set by the website owner are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies," which enable third-party features or functionality to be provided on or through the website.
In practical terms, a cookie allows a site to remember your preferences — such as language settings or the articles you have already read on energy and endurance formulas — so you do not have to re-enter that information each time you return. The file itself is a simple text fragment; it does not execute code and cannot access other files stored on your device.
