Privacy

As part of this, we believe that all our contributors and readers are entitled to privacy as they use our pages.

Email We do not collect email addresses in anyway, except for our voluntary mailing lists, all of which give clear instructions on unsubscribing and require positive confirmation that you wish to join. This means that entering an email address into a web form on our sites, or subscribing to a list via email will provoke a further email that requests confirmation that you wish to join. No one can sign you up for one of our lists without your permission, unless they have access to your computer.

Advertising None of our sites feature advertising that we benefit from in anyway. Third Party sites we link to, or reference dynamic content from, may contain advertising.

Cookies are a method by which a small text file (usually readable with a text editor) is stored on your computer in order to identify you to the web server at a later date. We may do that occasionally, to record prevent you having to log-in repeatedly, for instance. It is possible to turn cookies off completely, and you may wish to do this. However, you will lose functionality of certain dynamic content on Transdiffusion sites.

IP Addresses The internet works by giving each server and user a unique number - referred to as an IP Address - either permanently or on an ad-hoc basis. Our servers use IP Addresses in 3 ways: to provide the pages your web browser has requested; emails (and web form entries) sent to us generally record automatically the IP Address of the sender; our servers the IP Addresses of those who visit in case of abuse, but we don't link the address with specific users unless we detect abuse in the first place.

Web browsers Your web browser (eg Internet Explorer, Firefox, Mozilla, Opera etc) reports back certain information to our servers. This information is pretty anonymous - browser type, screen resolution, operating system - and this anonymous data is used by us to make sure we're not producing pages that the vast majority can't read.

Your browser also sends us slightly more specific information. This includes the page that referred you to us, any terms you used in a search engine to find us and which search engine you used, and which pages you visited whilst you were touring our sites (though not where you went afterwards, or unlinked sites you visited beforehand). We use this information to track the popularity of articles on our sites, the most popular search engines and what people are searching for. This information, although more specific, is still anonymous. We can't, and, frankly, don't want to identify you personally.
