Privacy

We do not ask you to register, and we do not collect names, addresses or payment details, because nothing is paid for here. Ordering, payment, delivery and returns all happen at checkout, wherever you place the order.

What is collected

Server logs. Our host records standard request data such as IP address, page requested, timestamp and user agent, for delivery and abuse prevention.
The calculators. The figures you type into the tools on this site are worked out in your own browser. They are not transmitted to us and not stored.

Links out

Buy buttons take you to a retail partner. Once you are there, that site's own privacy policy and cookies apply, and affiliate programmes generally record that the visit came from us so any commission can be attributed. We do not receive your personal details from that process.

Getting in touch

Write to contact@bthfst.net with any privacy question, including a request to know what a log holds about you, and we will answer.

Measuring before you order

You buy furniture for a tight room by the inch, and a photograph tells you nothing about the clearance left over. Our guides work out the footprint, the ceiling a top bunk needs and the load a frame carries.
