What this site collects

This site has no accounts, comments or forms, and I don't collect your name or email address here. Like most websites, the server keeps standard access logs (IP address, browser, pages visited) for security and troubleshooting.

Advertising

Some pages may show ads served by Google. Google and its partners use cookies to show ads based on your visits to this and other websites. You can turn off personalised ads in Google Ads Settings, and learn more in How Google uses information from sites that use its services.

Affiliate links

Some older posts contain affiliate links (for example Amazon, Rakuten and partner networks). If you buy through them I may earn a small commission at no extra cost to you.

Embedded content

Posts may include embedded maps and videos (Google Maps, YouTube). These behave as if you visited those sites and are covered by their own privacy policies.
