Privacy policy

What data do we collect about you?

Our website collects and uses some of your personal data.

When you submit a form, we record the date, the time and your truncated IP address (with the final part removed) as proof of your consent.

We also obtain the personal identification and contact details you fill in on the forms and the content of your messages. If you accept measurement cookies, data about your browsing is also collected.

How do we collect your data?

Data is collected through the fields you fill in on the contact and quote forms:

• name, company, CNPJ (Brazilian company number), email and phone;
• city and state;
• subject, product of interest, order details (quantity, time frame and sector) and message;
• résumé attached in the contact form under the Careers subject (the only case in which the website accepts a file).

Our website also collects information about your browsing through measurement cookies, only if you accept them (see below).

What do we use your data for?

We use your identification and contact details to reply to your message and questions, to prepare and send the quote you requested and, under Careers, to assess your résumé in Maxim’s hiring processes. This data is kept for as long as needed for these purposes.

The record of the date, time and truncated IP address of each submission serves as proof of your consent and is kept with the message sent to Maxim. Your full IP address is only used at the moment of submission, in the server’s temporary memory, to limit repeated submissions from the same connection; it is not recorded or sent to Maxim.

Who do we share your data with?

Form data reaches the Maxim team by email, through Microsoft 365. The website is hosted by Vercel. Measurement cookies, which only run with your consent, are Google’s. These providers process the data on Maxim’s behalf, only for the purposes of this Policy, and some of them may process it outside Brazil, in accordance with the LGPD.

The corporate film is only loaded from YouTube (Google) if you press play; from then on, YouTube receives data from your connection, such as your IP address, and processes it under its own policy.

If submission through the website fails, the website prepares the message for your own email app; in that case, it is sent through your email provider, without the record of date, time and IP address.

Consent

The data you enter in the forms is processed based on your consent, given in the authorization box of each form; measurement cookies are used based on your acceptance in the cookie notice. Consent is the free, informed and unambiguous statement by which you authorize Maxim Cimentos Especiais to process your data.

Therefore, form data and measurement cookies are only processed with your prior and express consent; the only exception is the momentary use of your IP address for website security, described above.

Your consent is requested in each form and, separately, in the cookie notice, showing Maxim Cimentos Especiais’ commitment to transparency and good faith toward its users and customers.

By ticking the authorization box on a form, you state that you are aware of and agree to this Privacy Policy, and that you know your rights and how to exercise them.

You may withdraw your consent at any time, free of charge.

Withdrawing consent may prevent Maxim from completing the service that depends on that processing, such as replying to your request or assessing your résumé.

What are your rights?

Maxim Cimentos Especiais guarantees its users and customers the data subject rights set out in article 18 of the General Data Protection Law. You may, free of charge and at any time:

• Confirm whether your data is being processed, in a simplified form or in a clear and complete format.
• Access your data, requesting a readable copy in print or by secure and reliable electronic means.
• Correct incomplete, inaccurate or out-of-date data.
• Limit your data when it is unnecessary, excessive or processed in breach of the law, through anonymization, blocking or deletion.
• Request the portability of your data, through a report of the registration data that Maxim Cimentos Especiais processes about you.
• Delete data processed on the basis of your consent, except in the cases provided for by law.
• Know which public and private entities Maxim Cimentos Especiais has shared your data with.
• Be informed about the possibility of not giving consent and about the consequences of refusing.
• Withdraw your consent, no longer authorizing the processing of your data.

How can you exercise your rights as a data subject?

• Email: contato@maximcimentosespeciais.com.br
• Phone: +55 (11) 4645-6839
• The website’s Contact form, with the subject “Privacy and personal data (LGPD, Brazil’s personal data law)”

To confirm that the request comes from the data subject, we may ask for documents or other proof of your identity before handling it.

How and for how long will your data be stored?

The personal data collected by Maxim Cimentos Especiais is used and stored for as long as necessary to achieve the purposes listed in this Privacy Policy, taking into account the rights of data subjects and controllers.

In general, your data is kept for as long as it is needed to reply to your message or request or to assess your résumé and, if there is a contract with Maxim, for as long as that contract lasts. At the end of the storage period, personal data is deleted or anonymized, except in the cases provided for in article 16 of the General Data Protection Law, namely:

• I. compliance with a legal or regulatory obligation by the controller;
• II. study by a research body, ensuring, whenever possible, the anonymization of the personal data;
• III. transfer to a third party, provided that the data processing requirements of the LGPD are met; or
• IV. exclusive use by the controller, with no access by third parties, and provided that the data is anonymized.

In other words, personal information about you that is essential for complying with legal, judicial and administrative requirements and/or for exercising the right of defense in judicial and administrative proceedings will be kept, even if the rest of your data is deleted.

This storage reflects our commitment to security and privacy. We use technical safeguards aimed at the confidentiality and integrity of your data, appropriate to the risks, with access control over the stored information.

What do we do to keep your data secure?

To keep your personal information secure, we use physical, electronic and managerial tools aimed at safeguarding your privacy.

We apply these tools taking into account the nature of the personal data collected, the context and purpose of the processing and the risks that any breach would pose to the rights and freedoms of the data subject.

Among the measures we adopt are the following:

• Only authorized people have access to your personal data.
• Access to your personal data is granted only after a confidentiality commitment.
• Your personal data is stored in a secure and reliable environment.

Maxim Cimentos Especiais is committed to adopting best practices to prevent security incidents. However, no website is entirely secure and risk-free. Despite all our security protocols, problems caused exclusively by third parties, such as cyberattacks, or by the negligence or carelessness of the user or customer, may occur.

In the event of a security incident that may result in significant risk or harm to you or to any of our users and customers, we will report it to those affected and to the Brazilian National Data Protection Authority (ANPD), in accordance with the General Data Protection Law.
