We use two audience-measurement tools — Google Analytics and Microsoft Clarity — to understand how the encyclopedia is read. Clarity records the browsing path (clicks, scrolling, pointer movements) anonymously, with input fields masked. No advertising, no sharing for commercial purposes. You can accept or decline them — you can change your choice at any time. We also count the pages you read with an anonymous, cookie-free measurement hosted on our own server: “Decline” stops it too.
