- Adults only. You must be 18 or over to create an account.
- Your details. Give us accurate information when you register and keep it up to date.

Lessons and class access
Some lessons are open to everyone. A free account opens further lessons. If you study with DaviDAD as your teacher, your teacher can unlock extra lessons for your class.
- Class access belongs to you personally and lasts while you are in the class. If you leave the class, we will remove it.
- We may add, change or remove lessons at any time.
- The service is free and we cannot promise that it will always be available. We try to keep it running and to fix faults quickly.
Copyright and acceptable use
The lessons, text, layout and design of this website belong to DaviDAD. You may use them for your own personal study. You may not:
- copy, print, save, record or republish the lessons, in whole or in part;
- share your login, or the lessons, with people who do not have their own access;

The website blocks copying and printing of lessons for this reason. If you want to use material in your own teaching, ask first at contact@davidad.casa.
Suspension, ending your account and changes
You can close your account at any time by emailing contact@davidad.casa. We may suspend or close an account if you break these terms, and we will tell you why where we reasonably can.
There are no paid memberships at the moment. If we introduce them, the price and terms will be shown clearly before you pay.
We may change these terms from time to time. We will publish the new version here with a new date at the top. If you keep using the website after a change, you accept the new terms.
Liability, governing law and contact
Liability. The lessons are for general learning, and we cannot promise any particular result. The website is provided as it is. To the extent the law allows, DaviDAD is not responsible for indirect losses, or for losses caused by things outside our control. Nothing in these terms limits any right you have by law that cannot be excluded.
Your data. Our Privacy Notice explains how we handle your personal data.
Governing law. These terms are governed by the law of Vietnam. If we have a problem, please contact us first and we will try to settle it fairly. Any dispute we cannot settle will be dealt with by the courts of Vietnam. This does not remove any consumer protection you have under the law of the country where you live.
