First-party cookie

First-party Cookies are created by a visited website a visitor entered directly. Using first-party cookies means it’s your domain collecting data. This translates into greater control and full ownership of data. In other words, you can handle the data responsibly and safeguard it as best as possible.

Website owners can use those cookies to automatically log users in, remembering language settings, gather analytics data for content personalization, and to other functions that ensure a better user experience.
