What we measure and why
We measure how the site is used (page views, use of the animations, reading of the posts, link clicks) to learn which content is useful and improve it. There are no ads, we don't sell data and we don't build profiles for any other purpose. We don't ask you to sign up or collect contact details unless you email us.
