Cookies are small pieces of data that your browser stores when you visit a website, alongside similar technologies such as local storage. They let a site remember who you are between page loads instead of treating every click as a stranger's first visit.
On a platform built around discretion, cookies are what keep a signed-in session private and secure, remember the preferences you have already set and reduce the number of times you are asked to re-authenticate.
