Privacy / updated 23 July 2026
Minimum data, clear choice.
The website works without analytics consent. Optional GA4 measurement starts only after explicit acceptance.
Contact form
The form does not store data on the server. It prepares a message in the user's email application. Data is transmitted only when the user sends that message.
Optional GA4 analytics
After consent, GA4 may measure page views, traffic source, approximate device information and events such as CTA clicks, form starts and qualified enquiries. Advertising measurement and ad personalisation remain disabled.
Consent is the basis for optional analytics. It can be declined or changed at any time through Privacy settings in the footer. The preference is stored locally under ml_analytics_consent.
Provider and further information
Google Analytics is the measurement provider after consent. Google's privacy information is available at policies.google.com/privacy.
