Here is some information on what types of information is received and collected when you visit roamingdownunder.com. In summary, I respect people's privacy and never give or sell personal information to third parties.
As with most other websites, the web hosting software collects data and stores it in log files. This data includes your IP (internet protocol) address, your ISP (internet service provider), the browser you used to visit this site (Internet Explorer, Firefox, etc), the date and time you visited this site and which pages you visited. Nothing identifies you personally.
I use monthly summaries of this information to see bulk trends such as total visitor numbers, which pages are most (and least) visited, and which countries the website is most commonly viewed from.
Some of the advertisers may use technology such as cookies and web beacons when they advertise on this site, which will send these advertisers (and Google, through the Google AdSense program) information including your IP address, your ISP, the browser you used to visit our site, and in some cases, whether you have Flash installed. They generally use this for geotargeting purposes (showing New York real estate ads to someone in New York, for example) or showing certain ads based on previous sites visited (such as showing cooking ads to someone who frequents cooking sites).
This website is not a blog, and has no comments system requiring e-mail addresses. The only way I can receive an e-mail address is if somebody chooses to send an e-mail to the address on my contact page. I do not, and will never, use senders' e-mail addresses for any purpose other than replying to that sender.
