Human Systems EcologyPrivacy & measurement
Useful signals.
Limited intrusion.
Measurement should help improve this work without turning visitors into profiles. This page explains what is collected, what is optional and how you can change your choice.
First-party effectiveness data
The site records a small set of anonymous events needed to understand whether its pages and invitations are useful: the page visited, CTA identifier and label, broad destination type, referring website domain, campaign tags, broad viewport category, and date and time.
This first-party record does not include your name, email address, IP address, full referring URL, browser user-agent, or a persistent visitor identifier. It is not used for advertising or individual profiling.
Optional Google Analytics
Google Analytics is loaded only after you select Allow analytics. It helps show how visitors discover and move through the site, which pages hold attention and which invitations are selected.
The installation disables Google Signals and advertising-personalisation signals. Google states that GA4 does not log or store IP addresses. Google may still use cookies and process information under its own terms and privacy practices.
Your choice
Your analytics preference is stored only in this browser. You can change it below at any time. Choosing not to allow Google Analytics does not restrict the site.
