All of the cookies we set are secure, first-party cookies. This means that cannot track you after you leave the site.

Our cookies do not expose any of your personal information, such as your name, email address, or password.

Opting In: If you live in a country under GDPR (or similar laws) OR you have Do-Not-Track set in your browser, you will have to opt in before we can set any non-essential cookies. This can be done using the "Cookie Consent" banner (not a pop-up) at the bottom of every page (above the footer). If you don't opt in, we will not set any non-essential cookies, which means that some of your preferences will not be remembered. If you do opt in, you will need to renew your consent at least once a year.
