Master USA LLC
Privacy Policy
Updated October 16, 2026
MasterCursos.PRO is operated by Master USA LLC, based in Orlando, Florida (USA). This policy explains what personal data we collect, why, who we share it with and how you can exercise your rights, including those under Brazil's LGPD and US privacy laws.
1. Data we collect
Data you give us: name, e-mail, WhatsApp, interests, level-test answers, messages sent to our virtual assistants, to the Master Specialist and to our WhatsApp, and the voice message you record for Rádio Master's DJ for a Day.
Student account: e-mail, name, lesson progress, quiz scores and certificates.
Purchases: processed by Hotmart. Hotmart sends us your name, e-mail and the product bought so we can unlock access. We never receive or store card data.
Site usage: pages visited, device type and essential session cookies. On Rádio Master we count listening time and approximate region (country, state and city provided by the network); we do not store your IP address.
2. How we use it
To serve you, recommend courses, unlock purchased courses, issue certificates, answer questions (by people or by AI supervised by the teacher), send VIP List news when you subscribe, air your voice message when you send it to DJ for a Day, and measure audience and site quality.
Legal basis: your consent (forms and VIP List), performance of a contract (purchased courses) and our legitimate interest in keeping the site safe and working.
3. Who we share it with
Only with providers needed to run the service: hosting and database (Supabase and the site's hosting platform), e-mail delivery, Hotmart (payments), WhatsApp/Meta when you talk to us there, and AI providers that generate support answers. We do not sell your data.
Data may be stored in the United States or other countries where these providers operate, under appropriate contractual safeguards.
4. How long we keep it
Contact and VIP List data: until you ask to leave. Student data and certificates: while the account exists and as required by law. DJ for a Day voice messages: up to 12 months. Radio statistics: aggregated.
5. Your rights
You may request access, correction, a copy or deletion of your data, or withdraw consent at any time. Every VIP List e-mail has an unsubscribe link.
For any privacy request, message our team on WhatsApp (the “WhatsApp” button in the site footer) with the word “Privacy”. We reply within 15 days.
6. Cookies
We use essential cookies and browser storage for login, preferences (language, radio volume) and to remember that you have signed up. Audience is measured in aggregate. You can clear cookies in your browser settings.
7. Security
We use encrypted connections (HTTPS), permission-based access control in the database and restricted staff access. No system is 100% immune; if a relevant incident happens, we will notify affected people and authorities where the law requires.
8. Minors
Courses are intended for adults, or for minors with the consent and supervision of a parent or guardian.
9. Changes
We may update this policy. The date at the top shows the version in force.
