Cookie policy

01

Essential storage

Essential storage supports language choice, administrator sign-in and isolated Material Lab sessions. Material Lab also keeps an active job reference locally so an accepted generation can resume after a refresh.

• greencycle-language: language choice
• Supabase authentication cookies: administrator sign-in only
• shangjian-material-lab-session and local active-job record: Material Lab continuity

02

Optional analytics

When configured and accepted, first-party analytics records public page paths, referral domains, device categories and fixed browsing events. PostHog may also receive this limited event set if separately configured; person profiles, automatic click capture and session recordings are disabled.

• Disabled until explicit consent; Do Not Track and Global Privacy Control are respected
• shangjian-analytics-visitor: random browser identifier valid for up to 90 days
• shangjian-analytics-session: random visit identifier renewed after 30 minutes of inactivity
• Raw identifiers are pseudonymised on the server and are not shown in management reports; search terms, form content and query strings are excluded
• Changing to Essential only clears these local identifiers and stops collection

03

Session attribution

The site may retain landing-page and campaign information in session storage so an enquiry includes its source. This record expires with the browser session and is used only when a form is submitted.

04

Change your choice

Use the Cookie settings control at the lower-left of public pages to accept or reject optional analytics at any time. Clearing browser storage also resets the choice.
