Privacy policy

1. Who is responsible

The controller of your data is OpusBer System — Eduardo Blanco, based in Indaiatuba, São Paulo, Brazil. For anything about your data write to opusber.system@gmail.com.

2. What data we collect

We collect only what is needed:

• Contact form: name, business, WhatsApp, email, service of interest and the goal you tell us about.
• Virtual assistant: the messages you write and any data you choose to share in the conversation.
• Technical data: page visited, language, visit source and approximate location (country or region) inferred from the IP address.
• Cookies and browser storage, as explained in section 4.

3. Why we use it and the legal basis

• Answering your request and preparing a proposal: pre-contractual procedures and your consent (art. 7, I and V of the LGPD).
• Answering your questions through the virtual assistant and following up by WhatsApp or email: consent and pre-contractual procedures.
• Measuring site traffic: only with your consent.
• Site security and abuse prevention: legitimate interest (art. 7, IX).

We do not sell your data or use it for automated decisions that affect you.

4. Cookies

We use two categories:

• Necessary: they store your language and your cookie choice and let the assistant and the form work. They do not require consent.
• Measurement: Google Analytics 4, for usage statistics. They are turned on only if you click “Accept” or enable them under “Customize”.

You can change your choice at any time with the “Cookies” link at the bottom of the page.

5. Who we share your data with

To provide the service we use providers that process data on our behalf: site hosting, database, automation and messaging (including WhatsApp), artificial intelligence services for the assistant and, if you accept measurement cookies, Google Analytics. They receive only what their function requires.

6. International transfers

Some providers may process data outside Brazil. In that case we require adequate safeguards, as set out in art. 33 of the LGPD.

7. How long we keep it

We keep your data for as long as it is needed to handle your request and the business relationship and, afterwards, until you ask for its deletion, unless a legal obligation requires us to keep it.

8. Your rights

Under art. 18 of the LGPD you may ask at any time for:

• Confirmation that we process your data and access to it.
• Correction of incomplete, inaccurate or outdated data.
• Anonymization, blocking or deletion of unnecessary data or data processed without your consent.
• Portability of your data.
• Information about who we share it with.
• Withdrawal of consent.

Write to opusber.system@gmail.com and we will answer within the legal deadline. You may also lodge a complaint with Brazil's National Data Protection Authority (ANPD).

9. Security

We apply reasonable technical and organizational measures: encrypted connections, restricted access to data and separation between clients. No system is infallible, but we work to protect your information.

10. Minors

The site is not aimed at minors and we do not knowingly collect their data.

11. Changes to this policy

We may update this policy. The date of the last update appears below. Last updated: November 13, 2026.
