Very little, and nothing you would expect from a shop or a service. This site has no user accounts, no sign-up forms, no checkout and no payment processing, so we never collect names, passwords, payment details or anything similar through the site itself.

What is collected is the ordinary technical information every website receives when a browser visits it:

• Usage and device information. Pages visited, approximate location at country or region level, browser and device type, and how a visitor arrived (for example, from a search engine). This reaches us in aggregated, statistical form, not as a profile of an identifiable person.
• Server logs. Like any website, our hosting keeps standard logs (such as IP addresses and timestamps) for security and to keep the site running.
• Anything you send us. If you contact us through the site’s published routes, we receive whatever you choose to include in that message — which is why we ask readers to send page URLs and descriptions of problems, not personal details.
