What Are Cookies?
Cookies are small text files (typically under 4KB) that websites store on your device when you visit. They help websites remember your preferences, keep you logged in, and understand how you use the site. This policy explains exactly which cookies UXUIPrinciples.com uses, why we use them, and how you can control them.
