Booking services
The calendar loads only after a successful enquiry. Calendly presents its own cookie controls, including Decline, I understand and Cookie settings; these are not hidden or overridden. Our Google consent choices do not control cookies on Calendly’s domain. Calendly may load security and payment-provider cookies even when you are booking a free call.
Other browser storage
bigcookie.consent.v1 stores your category choices in local storage for 180 days. bigcookie.enquiry.attribution holds visit attribution in session storage for the current tab. bigcookie.conversion entries prevent repeat conversion events during that tab’s session. These entries are not cookies. Conversion entries contain random identifiers, not your contact details.
Rejecting Google cookies blocks our Google tags before they load. Changing a previous choice to reject removes accessible first-party Google measurement cookies. The site cannot delete cookies belonging to other domains; those can be managed in your browser or the provider’s own controls.
