Terms of Use

Courses are sold and charged by Hotmart, which also handles installments, receipts and the 7-day refund guarantee. Each course's access period is shown on its page.

Access is personal. Team plans (when available) state how many people may use them.

Lessons, materials, brands and texts belong to Master USA LLC or their authors. Copying, recording, reselling or sharing the content without written permission is prohibited.

When a course is completed, the student receives a certificate of completion issued by Master USA LLC, with a verification code. It certifies completion of a non-degree course; it is not an academic diploma.

Part of the support and the Master Specialist use artificial intelligence. Answers are educational guidance and may contain mistakes; when needed, the question is forwarded to a teacher. For electrical and hazardous installations, always follow a licensed professional.

By sending a voice message and song requests, you authorize Rádio Master to edit and broadcast your message with your first name and city. Offensive messages or messages violating third-party rights are not aired.

You may not use the site to send spam or illegal content, to try to access restricted areas or to disrupt the service.

We do our best to keep the site online and the information accurate, but the service is provided “as is”. Valid prices and terms are those shown on the Hotmart checkout page at the time of purchase.
