This Privacy Policy describes how Black Box, operated by 69.204.611 RICARDO DA SILVA MARQUES (CNPJ 69.204.611/0001-58), Rua Coronel José Pessoa, 10, Brazil ("Black Box", "we", "us"), collects, uses and protects personal information when you visit blackboxdr.site or use our apps and digital products.

  • Account and purchase data: your name, email address, products purchased, order dates and amounts.
  • Assessment answers: responses you choose to give in our optional questionnaires, used to recommend a suitable program.
  • Usage data: basic information about how you use our apps, such as lessons completed and login times.
  • Technical data: browser type, device type, IP address and similar data collected automatically when you visit our website.
  • Support messages: the content of emails you send to our support team.

How we use your information

  • To answer support requests;

We do not sell or rent your personal information to anyone.

Payments

Payments are processed by trusted, PCI-DSS compliant third-party payment processors. Your full card number is sent directly to the processor and is never stored on Black Box servers. We receive only limited information, such as the last four digits of your card and the transaction status.

Sharing your information

We share personal information only with service providers that help us run our business, such as payment processing, email delivery, app hosting and analytics. These providers may only use your data to perform services for us. We may also disclose information when required by law or to protect our rights and the safety of our users.

Cookies

Our website uses cookies and similar technologies to keep you signed in, remember preferences and understand how visitors use our pages. You can block or delete cookies in your browser settings; some features may not work properly without them.

Data retention

We keep personal information for as long as your account is active or as needed to provide our services, and afterwards only as long as required for legal, tax or accounting obligations.

Your rights

Depending on where you live, including under the Brazilian LGPD, the EU GDPR or US state privacy laws such as the CCPA, you may have the right to:

  • Access the personal information we hold about you;
  • Correct inaccurate information;
  • Request deletion of your information;
  • Opt out of marketing communications at any time;
  • Request a copy of your data in a portable format.

To exercise any of these rights, email [email protected]. We will respond within the time required by applicable law.

Security

We use reasonable technical and organizational measures, including encrypted connections (HTTPS), to protect your information. No method of transmission over the internet is completely secure, but we work to protect your data and review our practices regularly.

Children

Our products are intended for adults aged 18 and over. We do not knowingly collect personal information from children. If you believe a child has provided us with data, contact us and we will delete it.
