Last updated: January 2026
This Privacy Policy describes how wi888 — a Sports Betting and online casino platform available at wi888.best — collects, uses, stores, shares, and protects the personal data of its users. This document was prepared in compliance with the General Data Protection Law (LGPD — Law No. 13,709/2018) and applies to all visitors and account holders on the platform.
At wi888, privacy is not a box-ticking compliance exercise — it is a real part of our commitment to the Brazilian player. You deserve to know what we do with your information, why we do it, and what your rights are. That is exactly what this policy explains, plainly and without the runaround.
1. Introduction and Data Controller
A wi888 acts as controller of personal data collected on this platform, as defined under art. 5, item VI of the LGPD. This means we are responsible for all decisions regarding the processing of your data — how it is collected, the purposes for which it is used, and how long it is retained.
This policy applies to:
- Visitors to wi888.best, regardless of whether they have a registered account;
- Users registered on the wi888 platform, including active, inactive, and closed-account holders (during the legal retention period);
- Anyone who contacts wi888 support through any channel.
By using the platform, you confirm that you have read and understood this Privacy Policy. If you have any questions, please contact our support team before completing your registration.
2. Personal Data We Collect
A wi888 collects only the data necessary for platform operation and compliance with applicable legal obligations. Data is divided into the following categories:
2.1 Data you provide during registration and platform use:
- Full name;
- CPF (Cadastro de Pessoa Física);

- Mobile phone number;
- Full residential address (for identity verification purposes);
- Identity documents (national ID, driver's license, or passport) submitted during the KYC process;
- Banking and payment data: Pix key, account number, credit/debit card details (tokenized — we do not store the full card number), Mercado Pago, PicPay, or other payment method information.
2.2 Data automatically generated during platform use:

- Device type, operating system, and browser used;
- Browsing history within the platform (pages visited, session duration);

2.3 Data received from third parties:
- Identity verification information from KYC service providers;
- Fraud prevention data from partners specialized in payment security;
- Information from restriction lists (such as responsible gambling self-exclusion lists) where required by applicable law.
Sensitive data: wi888 does not intentionally collect sensitive personal data (such as racial origin, religious belief, or genetic or biometric data) in the context of its activities. Should such data be voluntarily shared by the user, it will be handled with enhanced protection and used solely for the purpose stated at the time of collection.
3. How We Use Your Personal Data
A wi888 uses collected data solely for the purposes described below:
- Account registration and management: Creation, maintenance, and verification of your account, including the KYC process required for withdrawals and regulatory compliance;
- Financial transaction processing: Processing of deposits and withdrawals via Pix, credit/debit card, boleto bancário, Mercado Pago, PicPay, and TED transfer — always in BRL;

Not used for third-party advertising: wi888 does not use your personal data for ad targeting on third-party platforms, nor does it share your information with advertising networks for that purpose.
4. Legal Basis for Processing (LGPD)
All personal data processing carried out by wi888 has a legal basis under the LGPD (art. 7). The main legal bases used are:
- Contract performance (art. 7, V): Processing required to fulfill the service agreement entered into between you and wi888 at the time of registration — this includes account management, bet processing, and financial transactions;
- Compliance with a legal or regulatory obligation (art. 7, II): Processing required to comply with applicable Brazilian law, including anti-money laundering regulations and the sector's tax and regulatory obligations;
- Legitimate interest (art. 7, IX): Used for platform security, fraud prevention, and service improvement — always ensuring that legitimate interest does not override the fundamental rights and freedoms of the data subject;
- Consent (Art. 7, I): For sending marketing communications and promotions — consent is obtained freely, informedly, and unambiguously, and may be withdrawn at any time without affecting your use of the platform's other services;
- Credit protection (art. 7, X): Queries to credit protection systems and identity verification checks, where applicable to the identity verification process.
5. Sharing Data with Third Parties
A wi888 does not sell your personal data. Sharing with third parties occurs only in the strictly necessary cases listed below, always with contractual confidentiality and data protection safeguards:
- Payment processors: To process deposits and withdrawals via Pix, credit/debit card, boleto bancário, Mercado Pago, PicPay, and TED transfer. These partners act as data processors and are contractually required to protect the information they receive;
- Game providers: To enable the live casino, slots, and poker experience (such as Evolution Gaming and Pragmatic Play). Only the minimum data necessary for the gaming session is shared;
- KYC and fraud prevention services: For identity verification and risk analysis, using the data required for the verification process;
- Technology infrastructure: Servers, cloud services, and analytics tools used in the technical operation of the platform — all governed by contracts with specific data protection clauses;
- Competent authorities: When required by law, court order, or applicable regulation — such as in investigations involving money laundering, fraud, or other illegal activities. In such cases, data is shared only to the extent strictly necessary and, where legally permitted, with notification to the data subject.
Intra-group transfer: If wi888 is part of a corporate group, data may be shared internally for operational purposes, always in accordance with the same protection standards set out in this policy.
6. Cookies and Tracking Technologies
A wi888 uses cookies and similar technologies to ensure the platform functions correctly and to improve the user experience. The types of cookies used are:
- Essential cookies: Required for the platform's core functionality — such as keeping your session active, remembering your language preferences, and securing access. These cannot be disabled without affecting how the site works;
- Performance and analytics cookies: Collect information about how you navigate the platform (pages visited, session duration, errors encountered) in an aggregated and anonymized form. Used to improve site performance and usability;
- Functional cookies: Allow the platform to remember your settings and preferences across sessions, such as your preferred deposit method or recent bets;
- Marketing cookies (with consent only): Used to identify and track visitors across sessions for remarketing purposes — only after explicit consent has been given. You may refuse or withdraw this consent at any time through the platform's cookie settings.
You can manage your cookie preferences through your browser settings or via the preferences panel available on the platform. Disabling essential cookies may affect the proper functioning of some wi888 features.
7. Personal Data Security
A wi888 implements technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or improper destruction. Key measures in place include:
- 256-bit SSL/TLS encryption: All communication between your device and wi888's servers is encrypted using 256-bit SSL — the same standard used by financial institutions in Brazil;
- Data encryption at rest: Sensitive data stored on our servers is encrypted at rest, ensuring protection even in the event of unauthorized physical access to the infrastructure;
- Payment data tokenization: Credit and debit card details are tokenized — we never store the full card number in our systems;
- Role-based access control: Only employees with a justified operational need are granted access to user data, and all such access is logged and regularly audited;
- Two-factor authentication: Available for user accounts — we recommend enabling it for added protection;
- Security monitoring: Automated intrusion detection and anomaly monitoring systems continuously oversee the platform;
- Security testing: We conduct penetration testing and security audits on a regular basis with specialized partners.
In the event of an incident: If wi888 identifies a security breach that may pose a risk to data subjects, we will notify the Autoridade Nacional de Proteção de Dados (ANPD) and the affected users within the timeframes required by the LGPD — generally within 72 hours of becoming aware of the incident.
8. Data Retention and Deletion
A wi888 retains your personal data only for as long as necessary for the purposes for which it was collected, or for the period required by applicable law. The general retention criteria are:
- Active account: Data is retained for as long as the account remains active and for as long as necessary to provide the contracted services;
- After account closure: Essential data is retained for a minimum of 5 (five) years after account closure, in accordance with Brazilian tax and anti-money laundering legislation;
- Financial transaction data: Deposit, withdrawal, and betting records are kept for at least 5 (five) years for audit and compliance purposes;
- Support communication data: Support history is retained for 2 (two) years after account closure;
- Marketing data: Deleted immediately upon withdrawal of consent, unless another legal basis justifies retention.
Once the legal retention period has ended, your data is securely deleted or anonymized in a way that no longer allows identification of the data subject.

10. International Data Transfers
A wi888 may transfer personal data to servers or partners located outside Brazil in specific operational situations — such as cloud infrastructure, game providers, and security tools. When this occurs, we adopt the following safeguards:
- We verify whether the destination country provides an adequate level of data protection, as assessed by the ANPD;
- When the destination country does not offer equivalent data protection, we use standard contractual clauses, data processing agreements (DPA), or other mechanisms provided under art. 33 of the LGPD;
- All partners that receive data through international transfers are subject to the same confidentiality and security obligations established in this policy.
Under no circumstances is personal data transferred to countries that do not offer adequate protection guarantees, unless appropriate contractual safeguards are in place.
11. Minors
A wi888 is a platform intended exclusively for users aged 18 (eighteen) and over. We do not intentionally collect personal data from minors. Registration requires a date of birth and CPF, which are verified to confirm that the user meets the age requirement.
If we become aware that we have collected data from a person under the age of 18, we will take the following immediate steps:
- Account closure without prior notice;
- Freezing of all balances and transactions associated with the account;
- Deletion of the minor's personal data from the platform's systems within the operationally feasible timeframe;
- Report to the relevant authorities when applicable.
Parental and guardian responsibility: If you believe a minor has used the wi888 platform, please contact our support team immediately at suporte@wi888.best. We will take all appropriate measures to protect the child or adolescent involved.
12. Changes to this Privacy Policy
A wi888 may update this Privacy Policy periodically to reflect changes in legislation, our data processing practices, or platform operations. When material changes occur, you will be notified via:
- Email notification sent to the address registered on your account;
- A prominent notice on the platform upon your next login after the update;
- Updating the "Last updated" date at the top of this policy.
Continued use of the platform after changes take effect constitutes acceptance of the updated Privacy Policy. For changes involving new data processing that requires consent, we will request that consent explicitly before initiating the new processing.
We recommend reviewing this policy periodically to stay informed about how wi888 protects your data. The most recent version will always be available at wi888.best/privacy-policy.
13. Contact & Data Protection Officer (DPO)
A wi888 has appointed a Data Protection Officer (DPO), as required by art. 41 of the LGPD, who serves as the communication channel between the company, data subjects, and the National Data Protection Authority (ANPD).
