What this policy covers
This page covers basic site analytics, functional browser storage, and the advertising technologies active when Google AdSense is running on this site.
How advertising cookies work on this site
Google AdSense is active on this site
This site uses Google AdSense, a third-party advertising service operated by Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). Google AdSense uses cookies, web beacons, and similar technologies to serve advertisements based on your prior visits to this and other websites.
What Google collects
Google's advertising cookies may collect your IP address, browser type, device identifiers, pages visited, and behavioural signals across sites that use Google advertising services. This data is used to serve relevant advertisements and to measure their performance.
Managing your ad preferences
You can opt out of personalised advertising at any time by visiting Google's Ads Settings. You can also opt out of third-party vendor use of cookies for personalised advertising by visiting aboutads.info.
Data retention
Data collected through Google AdSense is retained according to Google's own data retention policies. Data collected directly by this site (such as correction emails) is retained only as long as needed to respond to the enquiry.
Functional preferences
Browser localStorage is used to remember your dark-mode preference and cookie consent status. This stores no personally identifiable information.
Analytics
We may use privacy-respecting analytics tools to understand which pages are most useful and where readers exit. Where analytics are active, they are configured to anonymise IP addresses.
Google AdSense cookies
When Google AdSense is running, Google may set cookies such as DSID, IDE, and NID on your device. These are Google's cookies, governed by Google's Privacy Policy.
External links
When you navigate away via an external link, that site's own privacy policy applies. We are not responsible for the data practices of third-party sites.
