Privacy

FAIL Cookie banner partner disclosure

banner_present: The page only displays an 'Access Denied' error message with no cookie or consent banner visible.
Fix: Ensure the cookie/consent banner is served even on error pages, or resolve the access-denied block so the site's standard consent banner loads.
partner_sharing_mentioned: No banner or consent copy is present, so no disclosure of data sharing with third-party partners appears on the page.
Fix: Display consent copy that explicitly discloses data sharing with third-party partners, even on error pages where tracking may occur.
partner_count_specific: Because no partner sharing is disclosed, no specific numeric count of partners is provided.
Fix: Include a specific numeric count of third-party partners (e.g., 'we share data with X partners') in the consent banner.
