1 What Are Cookies?

Cookies are small text files placed on your device by websites. They serve many purposes — some useful (like remembering your preferences), some privacy-invasive (like tracking you across the internet for ads). We only use the former.

Most browsers allow you to: view cookies stored by a site, delete individual cookies, block cookies from specific sites, or block all third-party cookies. Check your browser's Help section for instructions.
