Terms and Conditions

Thank you for checking out our Terms and Conditions.

Our lawyers are currently busy finalizing the complete legal text, but in essence here is how it works:

Placing an order and paying

When placing an order, you will be re-directed to PayPal. PayPal handles the payment between us, i.e. you pay to PayPal and the money are then in our account at PayPal.

In this way, your credit card information or PayPal details are never reaching lesson.one, they stay between you and PayPal.


Once your order is placed, we ship the book(s) to you, normally leaving us within 3 days – often faster. Books are shipped through the Danish postal service. Tracking is unfortunately not possible.

Your data

Once again: your credit card details only reach PayPal. Other data related to handling your order, e.g. your name, email, address, and country is stored only in our webservers, and not passed on to anyone else.

USA and Canada

At this point we do not ship and sell to USA and Canada, please place your order for the book with Amazon.


For any questions, please contact us at contact@lesson.one

Changes to Terms and Conditions

Terms and Conditions may change without notice, and will always be available at our website.
