What data is collected and why

This site collects minimal data. Here is what may be collected:

  • Analytics data — Page visits, traffic sources, and general usage behaviour via Google Analytics (managed through Google Tag Manager). This data is anonymised and used only to understand how the site is being used.
  • Cookieless analytics data — Page visits and general usage behaviour via PostHog, running in cookieless mode. Nothing is stored on your device and no lasting identifier is kept: visitors are counted with a privacy-preserving hash that resets daily. Data is processed on PostHog's servers in the EU.
  • Contact information — If you reach out via email, phone, or a contact form, your contact details are used solely to respond to your enquiry. This data is not stored in any database or shared with third parties.

No data is sold, rented, or shared with third parties for marketing purposes.

Legal basis for processing

Data processing on this site is based on:

  • Consent — Analytics and non-essential cookies are only activated after you give your consent via the cookie banner.
  • Legitimate interest — Basic technical data (e.g. server logs) necessary to keep the site running, and cookieless analytics (PostHog) that stores nothing on your device.

Cookies

This site uses cookies to enable analytics and remember your consent preferences. You can manage your cookie preferences at any time using the cookie settings button at the bottom of the page.

Cookie categories

  • Necessary — Required for the site to function. Cannot be disabled.

  • Functional — Remember preferences and settings. Only activated with your consent.
