Cookies and Website Storage
Your choice
Analytics is off by default. Accepting or rejecting it does not change access to the website or enquiry forms. lets you change your choice at any time.
Essential preferences and security
The browser stores your analytics choice in tg_analytics_consent_v1 for up to 180 days. Museum filters and scroll position use session storage during your visit. These preferences do not send your browsing history to the workshop. Hosting and Cloudflare security services may use technical storage needed to protect requests and prevent abuse.
Campaign context, only after analytics acceptance
tg_campaign_context_v1 uses session storage in the current browser tab for the first and latest page context and latest observed campaign labels. The record is no longer used after 30 minutes without activity or after 24 hours, and is reset on the next visit. Closing the tab normally clears session storage. Rejecting or withdrawing analytics removes this record. It contains public page paths and referring website origins, without complete URL queries or advertising click identifiers. Sharing it with an enquiry requires the separate optional form setting.
Google ad-click storage, only after a separate choice
tg_google_ads_choice_v1 and tg_google_ads_click_v1 use this tab's session storage only after the unchecked Google ad choice is selected. The first stores that choice and its notice version; the second stores available gclid, gbraid or wbraid identifiers and capture timestamps, without complete URLs or form contents. The choice lasts at most 24 hours. The identifier record is no longer used after 30 minutes without recorded activity or the choice's expiry and is discarded on the next access. Unticking the Google choice removes both records. This choice is independent of analytics and enables no advertising pixel. A further, unchecked enquiry choice is required before the identifier accompanies a submitted enquiry or any later qualified-lead measurement.
Google Analytics, only after acceptance
The website uses the existing Google Analytics property G-FV2MQSF5D6. Its _ga and _ga_* cookies distinguish visits and sessions and are configured here to expire after 180 days without extending that period on each visit. Measurement covers page visits and successful enquiries, not the text or photographs you submit. No advertising pixels are loaded by this website.
On withdrawal, the website disables analytics, removes its accessible first-party analytics cookies and reloads without the analytics library. Your choice is remembered separately from analytics cookies.
