What Are Cookies?

Cookies can be "session" cookies (deleted when you close your browser) or "persistent" cookies (remain on your device for a set period).

We also use similar technologies such as local storage, session storage, and web beacons, which function similarly to cookies. Throughout this policy, we refer to all of these as "cookies."
