Summary of Key Points
Six pillars of our approach to privacy and data protection at mx39
This Privacy Policy describes how the platform mx39 (mx39.best) collects, uses, stores, and protects your personal data. By creating an account or using any mx39 service, you confirm that you have read and understood this policy. We apply the General Data Protection Law (LGPD – Law No. 13.709/2018) at every stage of processing your information.
The mx39 is an online betting and digital casino platform designed exclusively for the Brazilian market. We operate at mx39.best and offer Sports Betting (with a focus on Brazilian football — Brasileirão Série A, Copa do Brasil, Libertadores), e-sports, crash games, Live Casino, roulette, jackpot, and the VIP Program.
For the purposes of this Privacy Policy, mx39 acts as controller of the personal data of users registered on the platform, as defined by the LGPD. This means we are responsible for decisions about how and why your data is processed.
In specific situations — such as payment processing via Pix, PicPay, or Mercado Pago — mx39 acts as the controller regarding data processed by our partner financial institutions, which have their own privacy policies.
When you register and use mx39, you provide us with the following information:
As you browse the platform, we automatically collect certain technical information:
Mx39 collects only the data strictly necessary to provide the contracted services and meet applicable legal obligations. Data minimization is a core principle of our operation.
Data collected by mx39 is used exclusively for the following purposes:
Mx39 never uses your data to make discriminatory decisions based on racial, ethnic, gender, or any other characteristic protected under Brazilian law. Your betting history is used solely to calculate VIP Program bonuses and personalize suggestions within the platform.
All personal data processing carried out by mx39 is grounded in one of the legal bases set out in the LGPD. The primary basis used for each purpose is:
| Purpose | Legal Basis (LGPD) |
|---|---|
| Account creation and management | Contract performance |
| Payment processing | Contract performance |
| Identity verification (KYC) | Compliance with a legal obligation |
| Anti-money laundering | Compliance with a legal obligation |
| Sending promotional communications | Consent |
| Behavioral analysis for platform improvement | Legitimate interest |
| Security and Fraud Prevention | Legitimate interest |
When processing is based on your consent, you may withdraw it at any time without affecting any processing already carried out.
Mx39 does not sell your personal data to third parties under any circumstances. Sharing occurs only in the situations below, always with appropriate protection:
To process payments, we share the necessary financial data with the following institutions, each with their own security and LGPD compliance policies:
We use cloud, security, and analytics service providers that may process data on our behalf as processors, always under contract with data protection clauses compliant with the LGPD.
Mx39 may be required to share data with Brazilian authorities — such as the Ministry of Finance, the Central Bank, or the Judiciary — when required by law, court order, or regulations applicable to the betting and digital entertainment sector in Brazil.
All data sharing is internally documented. You have the right to request information about who your data has been shared with over the past 12 months by contacting us at contato@mx39.best.
Mx39 applies strict technical and organizational measures to protect your personal data against unauthorized access, loss, alteration, or improper disclosure:
No security system is completely foolproof. In the event of a security incident that may affect your data, mx39 will notify the affected users and the National Data Protection Authority (ANPD) within the timeframes established by the LGPD.
You also play a role in keeping your account secure by using a strong, unique password, never sharing it with anyone, and immediately notifying mx39 of any suspected unauthorized access at contato@mx39.best.
Mx39 retains your personal data for as long as necessary to fulfill the purposes for which it was collected and to meet applicable legal obligations:
Once the applicable retention period has elapsed, data is securely deleted or anonymized so that the individual can no longer be identified. You may request early deletion of your data, subject to any legal retention obligations described above.
Mx39 uses cookies and similar technologies to ensure the platform functions correctly and to continuously improve the user experience. The types of cookies used are:
Required for the platform's basic operation — session authentication, bet slip, language preferences, and security. They cannot be disabled without affecting your use of the platform. They do not collect data for marketing purposes.
These help us understand how users navigate mx39 — which pages are visited most, how long users spend in each section, and where any difficulties arise. Data is aggregated and anonymized before any analysis. You can disable these cookies in your browser settings.
They store your usage preferences — such as theme, language, and betting settings — so you don't have to reconfigure them on every visit. They are automatically cleared when you clear your browsing data.
Mx39 does not use third-party cookies for behavioral advertising or remarketing. Tracking cookies for external partners' commercial purposes are disabled by default and will only be enabled with your explicit consent.
To manage cookies, access your browser settings. Most modern browsers — Chrome, Firefox, Safari, Edge — allow you to control cookies by type and by domain. Disabling essential cookies may prevent access to certain platform features.
The General Data Protection Law (Lei nº 13.709/2018) grants you, as the owner of your personal data, a set of rights that mx39 is fully committed to upholding:

Mx39 verifies CPF and date of birth at registration to identify and block underage accounts. Any account that circumvents this control using false documents is closed immediately upon detection.
Mx39 operates with a focus on the Brazilian market and prioritizes storing and processing data on servers located in Brazil or in countries that offer an adequate level of data protection as defined by the LGPD.
In specific situations — such as the use of cloud infrastructure providers — data may be transferred to servers outside Brazil. When this occurs, we ensure that:
You can request information about specific international transfers of your data by contacting contato@mx39.best with the subject line "LGPD Request – International Transfers".
Mx39 may update this Privacy Policy from time to time to reflect changes in data processing practices, new legal requirements, or improvements to our approach to privacy.
When we make significant changes, we will notify you at least 15 days in advance by email (to the address registered on your account) and via an in-platform notification. The date of the last update is always shown at the top of this document.
Changes required by immediate legal obligation may take effect without prior notice, with simultaneous communication to affected users. Continued use of the platform after the effective date of any changes constitutes acceptance of the updated policy.
We recommend reviewing this policy periodically. If you disagree with any changes, you may request account closure and deletion of your data before the effective date.
