8857bet Privacy Policy – LGPD Data Protection

1. About This Privacy Policy

This Privacy Policy describes how the platform 8857bet, accessible at https://8857bet.best, collects, uses, stores, and protects the personal data of its users. It was drafted in compliance with the General Data Protection Law (LGPD, Law No. 13,709/2018), Brazilian consumer protection legislation, and the applicable Banco Central do Brasil regulations governing digital financial transactions.

The goal of this Policy is to be straightforward and easy to understand — not a dense legal text that no one actually reads. If you have any questions about any section, our support team is available 24 hours a day in Brazilian Portuguese to help you before you make any decision.

This Policy applies to all users registered on the 8857bet, to unregistered visitors accessing the platform, and to anyone who interacts with our communication channels, including chat and email support.

2. Who Is the Data Controller

For the purposes of the LGPD, the controller of personal data collected by the platform is 8857bet, operator of the Sports Betting and online casino platform available at https://8857bet.best. The controller is responsible for all decisions regarding the processing of users' personal data, including purpose, means, and storage duration.

The data protection officer (DPO) designated by the 8857bet can be contacted by email at contato@8857bet.best with the subject line "LGPD Request". All requests are answered within 15 business days, as required by law.

3. What Data We Collect

The 8857bet collects three main categories of personal data, as described below:

The 8857bet does not collect sensitive data as defined by the LGPD (such as biometric, health, or sexual orientation data) unless strictly necessary for identity verification and only with the user's explicit consent.

Credit and debit card data are not stored on 8857bet — they are tokenized and processed directly by certified payment gateways (PCI-DSS), meaning even our internal team cannot access your full card number.

4. How We Use the Data Collected

Each piece of data collected by 8857bet has a specific, documented purpose. The main uses are outlined below:

• Service provision: create and manage your account, process bets on football (Brasileirão Série A, Copa do Brasil, Libertadores), MMA/UFC, volleyball, basketball NBB, e-sports and live casino, and settle results;
• Financial transactions: process deposits via Pix, bank slip (boleto), credit/debit card, PicPay, Mercado Pago, or TED, and process withdrawals to the bank account linked to your CPF;
• Identity verification (KYC): confirm that you are 18 or older, that the CPF provided is valid, and that the bank details belong to the same account holder;
• Security and fraud prevention: detect unusual behavior, multiple accounts, use of automation tools, and money laundering attempts, in compliance with Law No. 9,613/1998;
• User support: answer questions, resolve disputes, and maintain a service history for quality assurance purposes;
• Personalization: suggest relevant promotions (such as bonuses for Brasileirão or UFC betting) based on your usage history — always in an aggregated, non-intrusive way;
• Marketing communications: send emails and notifications about promotions and updates, only if you have given express consent during registration. You may withdraw this consent at any time;
• Legal obligations: comply with regulatory requirements from the Banco Central do Brasil, the Receita Federal, and other competent authorities, including reporting of suspicious transactions.

The 8857bet does not use your data for automated decision-making with significant legal impact without the possibility of human review — a right guaranteed by Article 20 of the LGPD.

5. Legal Bases for Data Processing (LGPD)

All personal data processing carried out by 8857bet is grounded in at least one of the legal bases set out in Article 7 of the LGPD:

• Contract performance (art. 7, V): processing is necessary to provide the services agreed upon at registration — betting, Pix withdrawals, bonuses, and support;
• Compliance with a legal or regulatory obligation (art. 7, II): user identification (KYC), transaction reporting to BACEN, and compliance with anti-money laundering regulations;
• Legitimate interest (art. 7, IX): platform security, fraud prevention, risk analysis, and continuous improvement of the user experience — always respecting the rights and reasonable expectations of data subjects;
• Consent (Art. 7, I): sending marketing communications by email or push notifications. Consent is collected in a clearly highlighted manner during registration and may be withdrawn at any time.

Whenever the legal basis is consent, 8857bet ensures that consent is freely given, informed, unambiguous, and documented. Revoking consent does not affect any processing that was lawfully carried out prior to revocation.

6. Sharing Data with Third Parties

The 8857bet does not sell users' personal data. Data sharing only occurs in the following situations, always limited to the minimum information necessary:

• Payment gateways: financial data is shared with certified payment processors (PCI-DSS) to handle transactions via Pix, boleto, credit/debit card, PicPay, Mercado Pago, and TED. These companies act as operators and are contractually prohibited from using the data for any other purpose;
• Game providers: minimal session data is shared with certified slots, live casino, and crash games providers to ensure the integrity of results. No identifiable data is transmitted beyond the anonymous session ID;
• Competent authorities: data may be disclosed upon court order or at the request of the Brazilian Central Bank, the Federal Revenue Service, or the Financial Activities Control Council (COAF), as provided for under Brazilian law;
• IT service providers: cloud infrastructure, security analysis tools, and transactional email services operate as sub-processors under contracts that impose the same confidentiality and security obligations required by the LGPD.

In all sharing scenarios, 8857bet requires partners to maintain security and confidentiality standards equivalent to those applied internally. Any contractual breach by a partner may result in the immediate termination of the relationship.

7. Cookies and Tracking Technologies

The platform 8857bet uses cookies and similar technologies to ensure services work correctly, personalize the user experience, and analyze platform performance. The cookies used fall into the following categories:

• Essential cookies: required for the platform to function — they keep your session active, secure login with two-factor authentication, and process financial transactions. They cannot be disabled without affecting your ability to use the platform;
• Preference cookies: remember your settings, such as language, preferred odds, and favorite sports (football, UFC, e-sports). These are optional and can be disabled in your browser settings;
• Analytics cookies: collect aggregated, anonymous data on how users navigate the platform, which pages they visit, and how long they spend in each section. This data helps 8857bet to continuously improve the experience;
• Security cookies: detect unusual behavior, unauthorized access attempts, and the use of automation tools to protect your account and the integrity of the platform.

To manage your cookie preferences, go to your browser settings (Chrome, Safari, Firefox, or any other). Rejecting essential cookies may prevent access to certain features of 8857bet, including login and deposit processing via Pix.

8. How Long We Retain Your Data

The 8857bet retains users' personal data for the minimum period necessary to fulfill the purposes for which it was collected, in compliance with the minimum legal retention periods established under Brazilian law:

• Registration and financial data: retained for at least 5 years after account closure, as required by Brazilian Central Bank regulations and tax legislation;
• Transaction history: retained for a minimum of 5 years for tax audit purposes, anti-money laundering compliance, and dispute resolution;
• Security logs: retained for up to 6 months, except in cases of active fraud investigation or court order;
• Support communication data: retained for up to 2 years for quality control purposes and resolution of potential disputes;
• Marketing data (with consent): retained for as long as consent remains active. Withdrawing consent results in the immediate removal of data from communication lists.

Once retention periods have expired, data is securely deleted or irreversibly anonymized so that it is no longer possible to identify the data subject from the remaining information.

9. Data Security

The 8857bet applies technical and organizational measures to protect users' personal data against unauthorized access, alteration, disclosure, or destruction. The key measures include:

• 256-bit SSL encryption across all communications between the user and the platform's servers;
• Passwords stored with one-way cryptographic hashing — not even our own team has access to your password;
• Two-factor authentication (2FA) available to all users and mandatory for withdrawals above R$ 5,000.00;
• Role-based access control (RBAC) — each team member at 8857bet only accesses the data necessary for their specific role;
• Continuous infrastructure monitoring with automatic alerts for suspicious access attempts or traffic anomalies;
• Tokenization of card data processed by PCI-DSS certified payment gateways;
• Encrypted backups with redundant storage locations to ensure data availability even in the event of hardware failure.

In the event of a security incident that could pose a risk or cause harm to users, 8857bet will notify the National Data Protection Authority (ANPD) and affected data subjects within a reasonable timeframe, as required by Article 48 of the LGPD. The notification will include the nature of the incident, the data involved, and the measures taken to mitigate the impact.

10. Your Rights as a Data Subject

The LGPD guarantees you, as the data subject whose data is processed by 8857bet, a set of rights that can be exercised at any time. Below are all the rights provided under Article 18 of Law No. 13,709/2018 and how to exercise them on our platform:

To exercise any of the rights listed above, send an email to contato@8857bet.best with the subject line "LGPD Request — [type of right]" and your registered CPF for identification. All requests are answered within 15 business days. In the event of a refusal, 8857bet will provide the reasons in writing.

11. Minors

The platform 8857bet is strictly prohibited for anyone under 18 years of age. The platform does not intentionally collect, process, or store personal data belonging to minors.

At the time of registration, all users must confirm they are 18 years of age or older. Date-of-birth verification via CPF is performed automatically during the identity verification process. Any account identified as belonging to a minor is immediately suspended, the data is preserved for the minimum legal retention period, and the case may be reported to the relevant authorities in accordance with Brazilian child and adolescent protection legislation (ECA, Law No. 8,069/1990).

If you are a parent or legal guardian and suspect that a minor has created an account on 8857bet, please contact us immediately at contato@8857bet.best. Our team will treat this as the highest priority.

12. International Data Transfers

In some cases, personal data collected by 8857bet may be processed on servers located outside Brazil — for example, by cloud infrastructure providers or by casino and slots game providers headquartered in other countries.

All international data transfers carried out by the 8857bet is subject to the guarantees set out in Articles 33 to 36 of the LGPD. This means data is only transferred to countries or organizations that offer a level of protection equivalent to Brazilian law, or through contractual instruments that ensure users retain the same rights.

The 8857bet does not carry out international transfers of registration or financial data for advertising or market analysis purposes. Any transfer is strictly limited to the technical operation required to deliver the contracted services — such as processing live casino games or analyzing odds for international sports.

13. Changes to This Privacy Policy

The 8857bet may update this Privacy Policy at any time to reflect changes in its services, Brazilian legislation, or data processing practices. Any material change will be communicated to users via their registered email at least 7 days in advance, except where urgent regulatory requirements apply.

The date of the last update is always shown at the top of this page. Continued use of the platform 8857bet after the changes take effect constitutes tacit acceptance of the updated version. If you disagree with the changes, you may close your account before the effective date, as described in the Terms and Conditions.

The current version of this Policy is always the one published at https://8857bet.best/privacy-policy. Previous versions may be requested from the DPO for historical reference.
