Essential preference cookie
The first-party dt-consent cookie stores cookie choices for 180 days. Language is determined by the page address; form content is not stored in this cookie. The preference record avoids asking the same question on every page.
Optional analytics
With permission, analytics may be used to understand site use. When enabled, _ga and _ga_* cookies are limited to 180 days. Ad personalization is disabled, and contact details, form text and search terms are excluded from measurement.
Changing your choice
Use “Cookie preferences” in the footer to accept, reject or withdraw permission. Rejecting analytics does not block navigation or project-form functionality.
