What this site keeps
There is no account to make here, and there is no sign-up form on this site yet, so I am not collecting your name or your email address. The pages are counted as visits by the service that hosts the site, so I can see how many people read a page and which pages get read. Those counts carry no name, no email and no address.
Shop links
Some links on this site lead to a shop that sells something. If you buy through one of those links, the shop pays me a small commission and you pay the same price you would have paid anyway. When you click one of those links, the shop you land on may save a cookie on your device so it can tell the sale started from here. That cookie belongs to the shop, and the shop's own privacy policy covers it.
What I do not do
There is no advertising on this site, and I do not sell anyone's details, because I do not hold any. If I add a sign-up form or a measurement tool later, this page will say what it collects before it goes live.
If you write to me, I keep your message so I can reply, and I do not add you to any list. The Contact page says where to write.
