"Cookies" are small text files that are downloaded to your computer or mobile device when you visit websites. First-party cookies are those set by the website you are visiting. First-party cookies are cookies used by domains other than the website you are visiting.
Similar to Cookies, local storage technology, when used, allows websites to store information on your computer or mobile device. Local storage is often persistent, and unlike "Cookies," data in local storage is not automatically transmitted over the internet each time you visit the website that stores them.
