The 31win handles your personal data with care and in full compliance with the General Data Protection Law (LGPD — Law No. 13,709/2018). This Policy explains what we collect, why we collect it, how we use it, and what your rights are as a data subject.
The 31win, operator of the platform available at 31win.click, is the controller of personal data collected from Brazilian users under the General Data Protection Law (LGPD — Law No. 13,709/2018). This means that 31win is the entity responsible for decisions regarding how data is collected, stored, used, and shared.
This Privacy Policy applies to all services offered by 31win: Sports Betting on football (Brasileirão Série A, Copa do Brasil, Libertadores), basketball (NBB), MMA/UFC, and other sports; online casino with slots, baccarat, roulette, and crash games; poker room; and all financial transactions carried out on the platform via Pix, boleto bancário, credit/debit card, PicPay, Mercado Pago, and TED transfers.
The 31win collects only the data necessary to provide platform services, meet legal obligations, and ensure user security. Data collection occurs at different points throughout your interaction with the site.
Data you provide directly:
Automatically collected data:
Third-party data: In specific fraud prevention cases, 31win may receive information from risk analysis bureaus or payment operators to confirm the legitimacy of transactions. This data is used exclusively for security purposes.
The data collected by 31win are used for specific, limited purposes. We do not use your data for purposes incompatible with those that justified its collection.
The LGPD requires that all personal data processing have a specific legal basis. The 31win bases its data processing activities on the following legal grounds set out in Article 7 of Law No. 13,709/2018:
Whenever we process data based on consent, we ensure the request is clear and specific, and that refusing or withdrawing consent does not prevent you from using the core services of 31win.
The 31win may share your personal data with third parties in the following limited and controlled circumstances:
The 31win uses cookies and similar technologies to ensure the platform works properly, improve the user experience, and — with your consent — for analytics and marketing purposes.
Types of cookies used:
You can manage your cookie preferences through your browser settings. Please note that disabling essential cookies may prevent access to key features of the 31win, such as keeping your session active or accessing your betting wallet.
We do not use tracking technologies that collect data outside our site environment or share information with third-party advertising networks without your express consent.
The 31win implements technical and organizational measures to protect your personal data against unauthorized access, loss, alteration, or destruction. Key safeguards include:
In the event of a security incident that may affect your personal data, 31win will notify the Autoridade Nacional de Proteção de Dados (ANPD) and affected users within the deadlines established by the LGPD, with clear information about what occurred and the measures taken.
The 31win retains your personal data for as long as necessary to fulfill the purposes described in this Policy, unless a longer period is required or permitted by law.
The general retention criteria are:
When data is no longer needed for any of the listed purposes and there is no legal obligation to retain it, 31win proceeds with the secure deletion or irreversible anonymization of the data.
The LGPD grants you a set of rights over your personal data processed by 31win. You may exercise any of them at any time, free of charge, through the platform's support.

The 31win is a platform exclusively for users aged 18 and over. We do not intentionally collect data from anyone under 18, and registration requires age confirmation along with a valid CPF, which is verified against the date of birth provided.
If we identify that data from a minor was inadvertently collected — for example, through unauthorized use of an adult's account — the data will be immediately deleted and the account closed. Legal guardians who become aware of such misuse should contact 31win immediately so that the necessary steps can be taken as a priority.
The 31win may send marketing communications — such as emails about promotions, new casino games, special odds on the Libertadores, or poker tournaments — only to users who have explicitly consented to this type of communication during registration or at a later time.
Every marketing communication from 31win includes a visible and functional unsubscribe link. Clicking it removes you from the marketing list within 48 hours. Unsubscribing from marketing does not affect essential transactional communications, such as withdrawal confirmations, security alerts, and account notifications.
Users under an active responsible gambling self-exclusion are automatically removed from all marketing lists and receive no promotional communications for the duration of the exclusion. This block is applied system-wide and requires no separate request.
To manage your communication preferences at any time, go to your account settings on the 31win or contact support with the subject "Marketing Preferences".
The 31win may update this Privacy Policy periodically to reflect changes in Brazilian legislation, particularly the LGPD and ANPD regulations, or to incorporate improvements to the platform's data protection practices.
When significant changes occur — such as updates to processing purposes, the types of data collected, or the legal bases used — you will be notified by email at least 15 days before the changes take effect. Minor editorial updates with no material impact may be made without individual notification.
The date of the last revision of this Policy is shown at the top of this page. We recommend reviewing this document periodically, especially after receiving a change notification from the 31win. Continued use of the platform after the effective date of any changes constitutes acceptance of the revised Policy.
For any questions, requests, or complaints regarding the processing of your personal data by 31win, you can reach us through the following channels:
Requests related to data subject rights are responded to within up to 15 business days, as established by the LGPD. Requests requiring more complex review may be extended, provided the data subject is notified of the reason and the new deadline.
If you are not satisfied with the response from 31win, you may submit your complaint directly to the National Data Protection Authority (ANPD), the federal regulatory body responsible for overseeing LGPD compliance in Brazil.
From registration to withdrawal, see how your data moves through the platform securely, with a defined purpose at every step.
The LGPD gives you real control over your data. Here are the rights you can exercise at any time in the 31win.
Data protection isn't just talk — it's the result of concrete choices in architecture, process, and culture
All communication between your mobile device or computer and the servers of 31win is encrypted to the same standard used by Brazilian banks such as Nubank, Itaú, and Bradesco. Your login credentials, banking details, and betting history always travel through a secure channel.
The 31win was built to comply with the General Data Protection Law (LGPD) from the ground up. We have a designated Data Protection Officer (DPO), processes in place to respond to data subject requests, and processing activity records as required by the ANPD.
The 31win does not sell, rent, or transfer user data to third parties for their own commercial purposes. We share only what is strictly necessary with payment processors and technical service providers — always under contract and with confidentiality obligations consistent with the LGPD.
The 31win offers 2FA for all accounts, adding an extra layer of security beyond your password. With 2FA enabled, even if someone obtains your password, they won't be able to access your account without the code sent to your phone. We strongly recommend enabling it for all users.
The 31win does not store data indefinitely. Each data category has a clear retention period, defined by the purpose of processing and the applicable legal obligations. When data is no longer needed and there is no legal requirement to keep it, it is securely and irreversibly deleted or anonymized.
Staff at 31win who handle personal data undergo dedicated privacy and LGPD training. Internal access to sensitive data follows the least-privilege principle — each person accesses only what is required for their role. Access is continuously audited and monitored.
