Counting visits
We use Google Analytics to count visits: which lists are opened, roughly where visitors are in the world, what kind of device they use and which files they download. It sets cookies whose names start with _ga. The numbers only help us decide which lists to improve. They are never sold and never used for adverts.
Visitors in the UK, the EU, the EEA and Switzerland are asked first, and nothing is counted unless they say yes. Everyone else is counted straight away. You can change your answer at any time with Cookie settings, at the bottom of every page. Saying no stops the counting and removes the _ga cookies.
Everything else
Pages and card pictures are served by Cloudflare, which keeps standard server logs. Fonts come from Google Fonts.
