What is measured
The site uses Google Analytics 4 to see which pages are read and from what kind of device. It informs which information to expand, not who anyone is.
How it is anonymised
The IP address is truncated before storage. Google's advertising signals and ad personalisation are switched off, so the data does not feed advertising profiles.
What there is none of
- No advertising and no sponsored placements.
- No third-party cookies for advertising.
- No data is sold or shared.
- No forms, accounts or subscriptions, so no names or addresses are collected.
How to opt out
Your browser can block analytics, and Google's opt-out add-on disables it across every site. The content works the same with analytics blocked: the site is static and does not depend on it.
Corrections and questions
Any error gets fixed. The verification policy and the source criteria are in methodology and sources which explains how to flag a detail that does not add up.
