Privacy

We do not ask you to register, and we do not collect names, addresses or payment details: ordering, payment and returns all happen at our retail partner, not here.

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

Available payment methods

Shopping from a phone

We have no app of our own. Checkout happens at the retail partner, in your browser or in that partner's own app, which you can find on either store:

Google Play App Store

These links go to the stores themselves. There is no BBTO app.

Buying in bulk

Nearly everything in our range sells by the pack, which makes a sticker price a poor guide. The tools here work out what a single piece actually costs and compare pack sizes across the whole range.
