To help us refine the design of the website and newsletter, we track the trends of our readers. Each reader of the website remains anonymous, but the tracking of the trends helps us to see what topics and documents are of most interest, which can inform future refinements. This information is not shared with external parties, and only used to improve how our website supports future visitors. We use Fathom to see trends from website visitors, and Campaign Monitor / MailChimp to see trends on our email newsletter. 

We have a subscription-based email mailing list for those interested, and we do not share this list with any other parties.
