Overview
Analytics and advertising cookies, including Microsoft Clarity, are on by default. You can turn them off at any time with Decline on the cookie banner or Cookie choices at the foot of any page.
Necessary (always on)
nbr_consent: remembers your cookie choice. Form protection: a hidden spam-blocking field that stores nothing.
Campaign tags (this visit only)
nbr_visit: the campaign tags, landing page and time of this visit. Cleared when you close the tab.
Ad click (on unless you decline)
nbr_attr: the Google or Microsoft ad click that brought you here, kept up to 90 days. Declining deletes it.
Analytics (on unless you decline)
Google Analytics (_ga, _ga_*), kept up to 2 years.
Microsoft Clarity (_clck, _clsk, CLID and related), kept up to 1 year. Clarity records how pages are used; it masks everything typed into forms.
Advertising (on unless you decline)
Google Ads (_gcl_au and related), kept up to 90 days.
Booking
Calendly may set its own cookies when you book.
Changing your choice
Use Cookie choices at the foot of any page. If you decline, analytics, advertising and Clarity stop, and the stored ad click is deleted at once.
