Cookies are small text files placed on your device when you visit a website. We also use similar technologies — local storage, session storage, pixels and the GTM dataLayer — for the same purposes. Throughout this policy "cookies" refers to all of them.
On your first visit you see a consent banner. Strictly necessary cookies load by default — they are required for the platform to function and the ePrivacy Directive does not require consent for them.
Analytics and marketing cookies are denied by default via Google Consent Mode v2. They only load after you click Accept all or enable the corresponding switch in Manage preferences. Your choices are stored in the wsu_cc_consent cookie for 365 days; revisit the "Manage cookies" link in the footer at any time to change them.
The table below lists every cookie that may be set when you use the site. Durations are upper bounds — some cookies expire sooner if you sign out or clear your browser storage.
