Cookie policy

Cookies are small pieces of information stored by a website in your browser. Similar technologies, including browser storage and security scripts, can support website functions without being advertising trackers.

The website does not include advertising trackers, a marketing mailing-list widget or an embedded booking calendar. Fonts are served from the website itself. The sample size calculator runs in your browser; its inputs are not submitted as an enquiry.

Cloudflare hosts and protects the website. The enquiry form uses Cloudflare Turnstile verification, which processes browser and device signals to detect automated requests. Depending on the security configuration and challenge, Cloudflare may use strictly necessary cookies or browser storage to support security checks.

Cloudflare explains these features, cookie purposes and applicable durations in its cookie policy and Turnstile Privacy Addendum. Security cookies, where used, are controlled by the relevant Cloudflare service and its configuration.

You can use your browser settings to inspect, block or delete cookies and site data. Blocking security scripts or essential browser storage may prevent enquiry verification from completing. You can send a general enquiry to [email protected] instead.

If optional analytics, advertising or other non-essential storage features are introduced, this policy and the relevant visitor choices will be updated before those features are enabled.

Our privacy policy explains enquiry handling, providers, international processing and your data protection rights.
