Our site processes the absolute minimum data required to deliver Web pages to you. Only a small percentage of the data survives longer than your request for a page. The remaining data is stored on a secure server at a secure site and is regularly purged from disk.
What Survives and Why?
Cookies are one way to transfer data from one Web page to another so you do not have to retype the data. You control cookies with settings in your Web browser. Our Web site does not need cookies. If you turn cookies off, the URL in the Web browser will contain an extra an extra field to help our Web server serve you.
Here is a URL from a browser with cookies on:

Our cookies are set to disappear when you close your browser and never store anything other than the cookie id field.
Your browser may choose to send us a field containing your browser brand and version. We keep that string for short while to check against the list of browsers we use in testing. We also keep a summary of browsers to track long term trends.
Your browser has to send us a request for a page so we know what page to send to you. We keep that request for short while so we can improve navigation between pages. We also keep a summary of page request so we can remove pages that are no longer used.
When you ask for extra information, your request becomes an email to us and we keep the email until we are sure you receive a useful answer. Your request might also be used to improve the information in our current Web pages. Your request is not passed on to any other organisation unless you specifically ask use to forward the information.
Your page and information requests go through the Internet. Some Internet service providers are required by their local laws to keep information for law enforcement agencies.
The feedback forms help us help you. We need an email address so we can send you an answer. When you send us feedback or a question, we send a copy of your request to you immediately. You get to see exactly what we see. Nothing is sent to any other organisation unless you ask us to send the information.
We may quote feedback questions on Web pages when expanding the pages. In those cases, we include only your initials and country.
Our surveys help us help you and other people. If you supply an email address, we will send you a summary of the survey results. Your name and email information is not attached to your survey answer so there is no way people can connect answers with individuals.
Our summaries, the ones with no names or email addresses, may be sent to people who can change things. If we survey road usage in Sydney, the summary results might go to politicians and the newspapers. Your name and email address are never included with the summary results. You will receive a copy of the summary so can send the summary to whoever you think will make a difference.
Our servers are locked in a secure site that protects against fire, storm, and theft. We use the Apache Web server because Apache is proven in 50,000,000 Web sites. We use PHP and PXL because both are easy to keep secure.
There is advertising on our site. We advertise only suppliers who we use regularly. There are no tricky linked images or cookies to track your way from our site to their site, no pop-ups, pop-overs, pop-unders, or interstitials.
Once you leave our site to visit another site, we cannot control what that site does. That is one of the reasons we open all external sites in new windows. If there is a problem with their site, you can just close the window.
Occasionally you may receive junk mail using our domain name because the junk mail creators like to pretend their email is from a legitimate source. You can add domain source checking to your email account to reduce junk mail. Your mail server will then check the mail is from a server belonging to the domain listed in the sending address.
