Privacy Notice

This notice explains how this site handles information in connection with its reference material and contact form. This site is an independent information site. It has no accounts, payments, newsletter or registrations. A reader can view the reference information without creating an account or joining a mailing list.

Information entered in the contact form

When a visitor uses the contact form, the form receives the name, e-mail address and message entered by that visitor. This information is used only to reply to the enquiry. The name and e-mail address allow a reply to be addressed, while the message gives the context needed to respond.

Visitors should include only information relevant to their question. The contact form is not an account or registration service. Information entered there is not used to enrol a visitor in a newsletter, arrange a payment or create an account.

Automatic anti-spam check

The contact form uses an automatic anti-spam check. Its purpose is to help distinguish ordinary enquiries from unwanted automated submissions. This check operates as part of the form and does not change the stated purpose for which the name, e-mail address and message are used: replying to the visitor.

Aggregate measurement of visits

Visits to this site are measured in aggregate. The measurement is used to understand visit activity as a whole, not to identify a reader. Aggregate measurement concerns patterns across visits rather than identifying a particular person who has read a page.

This measurement is separate from the contact form. Reading a page does not require a visitor to provide a name or e-mail address through the form. Where a visitor does choose to send a message, the details supplied there are handled for the reply purpose described above.

Pages outside this site and questions

Some pages linked from this site are outbound pages provided elsewhere. Those pages have their own privacy rules, which may differ from the practices described in this notice. The privacy arrangements for an outbound page are determined by the provider of that page, rather than by this site's notice.

Questions about data handled by this site can be sent through the contact page. A message sent there should relate to the question being raised, and the form details are used only to reply. This notice describes the stated information practices of this independent reference site; it does not set the privacy rules for other pages.
