1. What Are Cookies
Cookies are small text files stored on your device by your web browser when you visit a website. They allow the site to remember your actions and preferences (such as login status) over a period of time, so you don't have to re-enter them each time you visit.
Cookies can be "session" cookies (deleted when you close your browser) or "persistent" cookies (remain until they expire or you delete them).

- To enable essential platform functionality (login sessions, security)

- To analyze site traffic and usage patterns
- To improve the performance and user experience of our Services
3. Types of Cookies We Use
