We take privacy issues seriously here, and for this reason we only collect the information required to process your order, and clarify it in case of a query.
The site is set up so that you don't need to register to browse the products, only to buy things through the shopping cart system. The financial side of things is handled through Paypal, as it allows us to take online payment using a secure and private system, consequently all financial data stays with Paypal and is not made available to us.
