Privacy Policy.

What this site collects, what it uses it for and what your rights are. In plain language.

Talk to ARX

Provisional version of November 10, 2026. Applies to the ARX Protocol website.

ARX Protocol treats privacy as part of its work. This policy explains, in plain language, which personal data we collect on this site, what we use it for, who we share it with and what your rights are, under the General Data Protection Law (Law No. 13,709/2018, the LGPD).

1. Who is responsible for your data

The data controller is ARX Protocol [legal name to be filled in], registered under CNPJ [to be filled in], headquartered at [address to be filled in], São Paulo, SP.

Contact for privacy matters: contato@protocolarx.com.br. Data protection officer: [name to be filled in].

2. What data we collect and why

Technical access logs: IP address, date and timeOn every access to the siteSecurity and operation of the site, and compliance with the Marco Civil da Internet (Brazil's internet civil rights framework)Legal obligation (art. 7, II) and legitimate interest (art. 7, IX)

We do not ask for sensitive data on this site. Please do not send documents, passwords or health information through the form.

To organize and route contacts, we use automated service tools, including artificial intelligence. They read your answers to take your case to whoever handles the matter and to prepare the first reply. If a decision about you is made solely by automated means, you may ask for it to be reviewed (LGPD, art. 20).

3. Cookies

Cookies are small files that the site stores in your browser. We use three types:

  • Essential: store your choices, such as language, light or dark version and your response to the cookie notice. They do not depend on consent.
  • Measurement: show how the site is used. They are only activated if you accept.
  • Advertising: let us measure the results of our campaigns on Google and Meta (Facebook and Instagram). They are only activated if you accept.

You can change your mind at any time:

4. Who we share with

We do not sell personal data. We share only with those who help us operate the site and serve you:

  • website hosting and email provider;
  • providers of the service tools that organize and answer contacts, including artificial intelligence;
  • Google and Meta, for measuring the site and ads, only if you accept cookies;
  • WhatsApp, when you choose to contact us through that channel;
  • authorities, when there is a legal obligation or a court order.

Some of these providers store data outside Brazil. In those cases, the transfer follows the LGPD rules on international transfers.

5. How long we keep it

  • Contacts and proposals: for as long as the conversation lasts and for up to 5 years afterward, to meet legal deadlines.
  • Measurement and ad data: up to 14 months.
  • Access logs: 6 months, as required by the Marco Civil da Internet.

After these periods, the data is deleted or anonymized.

6. Your rights

You may, at any time and at no cost:

  • confirm whether we process your data and request access to it;
  • correct incomplete or outdated data;
  • request the deletion, blocking or anonymization of unnecessary data;
  • request portability;
  • find out who we share your data with;
  • withdraw the consent you gave.

To exercise any of them, write to contato@protocolarx.com.br. We respond within 15 days. You may also file a complaint with Brazil's National Data Protection Authority (ANPD).

7. How we protect it

The site uses an encrypted connection. Access to the contacts received is restricted to the ARX people who need them to serve you. No system is completely immune to failures. If an incident occurs that may cause relevant risk, we will notify the affected data subjects and the ANPD.

8. Children and teenagers

This site is intended for adults and businesses. We do not knowingly collect data from anyone under 18.

9. What this policy does not cover

This policy covers only this site. The systems ARX installs for clients, such as cameras, access control and alarms, are governed by the contract for each project. In those, the client is responsible for the data of the people who move through their space.

10. Changes to this policy

We may update this text. The date at the top indicates the version in effect. Important changes will be announced on the site itself.

11. Protected content

The texts, images and case studies on this site are for the exclusive use of ARX Protocol. Copying, reproducing or using this content without written authorization is not permitted. The site uses technical measures to make copying difficult, and the full rules are in section 5 of the Terms of Use.
