Cookies and local storage
The site offers optional Google Analytics. Google Tag Manager and Google Analytics are blocked unless you select “Accept analytics”. Rejecting analytics is equally available and does not affect access to the site. Hosting or security providers may set strictly necessary cookies or retain request logs to deliver and protect the site.

Forms and newsletter
Professional enquiry forms are submitted directly to Formspree, which may use technical and anti-spam information. Newsletter forms are submitted directly to Buttondown. Neither service is embedded as a tracking widget by this site.
Embedded content and analytics
No third-party video or social-media embeds are loaded on the audited pages. Training videos are local placeholders unless a local media source is supplied. If you accept analytics, Google Tag Manager loads container GTM-MGSLVKBV and may load Google Analytics. Google may then receive usage information such as pages viewed, approximate location, device and browser information, referrer and interaction data, and may set analytics cookies. The site does not use advertising tags. Cloudflare Web Analytics is not enabled by the application code.
Managing storage
You can clear local storage using browser controls. Doing so resets saved calculator documents, theme choice, training progress, locally saved activity responses and the saved analytics preference. Use “Cookie preferences” in the footer to accept or reject analytics at any time. Withdrawing consent reloads the page without analytics; use browser controls to remove any Google cookies already stored. If advertising or other tracking is introduced, this page and the consent controls must be updated before those tags are published.
