Privacy and cookies

Reading, searching and learning

The published pages can be read without an account. The site serves its own fonts, styles and illustrations. Its learning tools perform their calculations in your browser. The site runs without advertising tags. Optional Google Analytics is described below.

Using the site search sends the search terms in the page address to the web server so it can return matching records. As with other requests, the hosting service may record the address requested, connection information such as an IP address, the time and the response code in its access or security logs. Please keep personal information out of searches.

Editorial correction notes

The contact page uses essential cookies to protect its form and display the result of a submission. These cookies support the contact function. The archive stores the page or topic, the suggested correction, any source link and the date in a private editorial inbox. Notes are available to the site operator for checking and are never automatically published. The form does not ask for your name or email. Please do not include pupil information, addresses, or copies of private records.

Links to other websites

When you follow a link to a school, trust, government service or teaching resource, you are visiting a separately operated site. Its privacy notice applies there. Questions about content or information submitted to this archive can be raised through the contact page.

Optional Google Analytics

With your permission, this website uses Google Analytics 4 to measure public page visits and improve the site. Google receives page information and browser/network data when analytics is enabled. Google scripts are not requested before you choose Allow analytics. Choose Reject analytics to keep them disabled, or use Analytics preferences to change or withdraw your choice. The choice is stored in this browser under serallo.analytics-consent.v1 and is valid for 180 days; clearing site data removes it. Google Analytics may set _ga and ga* cookies with a 180-day expiry that can be refreshed on use. Advertising features, Google signals and advertising personalisation are disabled. Page and referring addresses are sent without query strings or fragments. We do not send form fields or tool entries to Google Analytics. The loader is disabled on recognised private routes and pages marked noindex in their HTML metadata. Google may process information outside the UK. Withdrawing consent disables further analytics for this site and removes the Analytics cookies this code can access; it does not erase information already sent to Google.
