At 399w, your personal data is handled with care. This policy explains in plain language what we collect, how we use it, how we protect your information, and what rights you have under the LGPD.
Before reading the full document, here are the key points in plain language — no unnecessary legal jargon.

🔐 LGPD Law No. 13,709/2018All information transmitted between your phone or computer and 399w's servers is protected with SSL 256-bit encryption — the same security standard used by major Brazilian banks such as Itaú, Bradesco, and Banco do Brasil. Your financial and personal data never travels in plain text.
🔒 SSL 256-bit on all connections399w never sells users' personal data to third parties for commercial purposes. Data sharing is limited to essential operational partners — such as Pix payment processors — and to legal obligations. Under no circumstances is your data traded or disclosed for third-party marketing without your express consent.

399w uses the personal data it collects strictly for the purposes described below. No data is processed for any other purpose without prior notice and, where required, without the user's consent.
The LGPD requires that all personal data processing have a valid legal basis. 399w grounds its processing of user data on the following legal bases set out in Article 7 of Law No. 13,709/2018:
Where processing is based on consent, you may withdraw that consent at any time at no cost. Withdrawal does not affect the lawfulness of processing carried out prior to it. To withdraw consent, visit your account settings or reach out via privacidade@399w.best.
399w does not sell personal data of users. Data sharing is limited to the situations described below and always restricted to the minimum necessary for each purpose:
Essential operational partners: 399w shares data with service providers necessary for the platform to operate:
Legal and regulatory authorities: 399w shares data with public authorities when expressly required under Brazilian law — such as requests from the Judiciary, the Public Prosecutor's Office, the Federal Police, Receita Federal, or COAF. Such sharing is carried out strictly within the limits of the legal request, without disclosing more information than what is asked for.
Corporate transactions: In the event of a merger, acquisition, or restructuring of the company operating 399w, user data may be transferred to the successor entity, always with the protections set out in this policy maintained and with prior notice to users.
399w never sells, rents, or trades users' personal data with advertisers or data brokers. It never shares betting or financial data with employers, family members, or any third party not authorized by law. It never transfers data to countries without an adequate level of protection without the safeguards required by the LGPD.
399w implements appropriate technical and organizational measures to protect users' personal data against unauthorized access, loss, destruction, alteration, or improper disclosure. The key security measures in place include:
In the event of a security incident that results in risk or harm to users, 399w will notify the ANPD (Autoridade Nacional de Proteção de Dados) and the affected users within the timeframes set out in the LGPD, providing information about the nature of the incident, the data involved, and the measures taken to mitigate it.
The LGPD grants you, as the holder of personal data processed by 399w, the following rights, which may be exercised at any time at no cost:
Request confirmation of whether processing is taking place and obtain access to the personal data 399w holds about you, including the categories of data and the purposes of processing.
Request the correction of incomplete, inaccurate, or outdated personal data, such as an incorrect name, wrong date of birth, or outdated email address.

To request the transfer of your personal data to another service provider, in a structured, machine-readable format, where technically feasible.
Object to the processing of data carried out on the basis of legitimate interest where there are valid grounds for doing so, in accordance with the LGPD.
To withdraw consent given for processing based on this legal ground, at any time and without the need for justification, at no cost and without affecting access to the core service.
To exercise any of these rights, contact the 399w DPO by email at privacidade@399w.best. The response deadline is up to 15 business days, as established by the LGPD. If a request is denied, 399w will explain the reasons for the refusal, and you may file a complaint with the ANPD (Autoridade Nacional de Proteção de Dados).
399w retains users' personal data for as long as necessary to fulfill the purposes for which it was collected, in compliance with the minimum retention periods required by Brazilian law. The main retention periods are:
After account closure and once all legally required retention periods have been met, all personal data is securely deleted or irreversibly anonymized. Anonymized data is not considered personal data under the LGPD and may be retained for aggregated statistical analysis.
To request early deletion of your data — within the limits permitted by law — please contact our DPO at privacidade@399w.best. 399w will respond within 15 business days, indicating which data can be deleted immediately and which must be retained due to a legal obligation, with a specific justification for each category.
The 399w platform is strictly intended for users aged 18 and over. 399w does not intentionally collect personal data from minors. The registration process includes date of birth verification, and the platform performs identity verification (KYC) that includes age confirmation.
If 399w determines that it has collected data from a person under the age of 18, that information will be deleted immediately, the account will be closed, and, where applicable, the incident will be reported to the relevant authorities in accordance with Brazil's child and adolescent protection legislation (ECA — Law No. 8,069/1990).
If you are a parent or legal guardian and believe that a minor in your family has created an account on 399w, please contact us immediately at suporte@399w.best. The account will be closed and the data deleted at no cost and without penalty.
Some of 399w's technical and infrastructure partners may have servers located outside Brazil. When personal data is transferred internationally, 399w ensures that:
Most personal data belonging to 399w's Brazilian users is processed and stored on servers located in Brazil or in countries with an adequate level of protection recognized under Brazilian regulations.
399w may update this Privacy Policy periodically to reflect changes in Brazilian law, betting industry regulations, security practices, or platform operations. All material changes will be communicated at least 7 days in advance via the registered email address and through an in-platform notification.
The date of the last update is always shown at the top of this document. Continued use of the platform after any changes take effect constitutes acceptance of the revised policy. If you do not agree with the changes, you may close your account and request data deletion before the effective date of those changes.
To exercise your rights under the LGPD, clarify any questions about this Privacy Policy, or report any concerns regarding the processing of your personal data by 399w, please contact the Data Protection Officer (DPO):
When you register with 399w Whether you're betting on the Brasileirão, following a UFC card, or trying out the live casino slots, you're sharing personal information — your name, CPF, phone number, and financial details. It's natural to want to know what happens with that information, who can access it, and how long it's kept. This policy exists to answer those questions plainly, without filling pages with legal jargon nobody reads to the end.
The 399w collects data because it needs it to operate. Your CPF is required to verify that you are 18 or older and that you are who you say you are — a legal requirement for sports betting platforms in Brazil. Your phone number and email are needed to confirm your registration, send security alerts, and communicate account-related information. Your Pix key is required to process withdrawals. None of this data is collected out of curiosity or to be passed on to third parties — each piece of information serves a specific purpose and is retained only as long as that purpose requires.
Pix transformed the way Brazilians relate to digital finance — making payments instant, available around the clock, and free of charge. The 399w has embraced this model from day one: instant deposits and withdrawals in up to 5 minutes, 24 hours a day. When you request a withdrawal, 399w needs to process the transaction through Brazil's Central Bank systems and partner banks — this involves transmitting financial data securely and in encrypted form. No financial data travels in plain text between the platform and the payment systems.
Identity verification (KYC) can raise questions. Why does 399w ask for a photo ID before the first withdrawal? Because Brazilian regulations for the sports betting sector require platforms to verify users' identities before releasing payments — this protects both the user against fraudulent use of their account and the financial system against money laundering. Submitted documents are stored in an encrypted environment, accessible only by the compliance team, and are deleted after the minimum legal retention period. They are not shared externally and are not used for any purpose other than verification.
The LGPD gave Brazilians an important set of rights over their personal data — and 399w DPO Email
The cookies on 399w work transparently. Strictly necessary cookies — those that keep you logged in and protect your session against CSRF attacks — cannot be disabled because the platform simply cannot function without them. However, tracking cookies for advertising or detailed behavioral analysis are only activated with your explicit consent, which can be managed in your account or browser settings. This means 399w will not track your browsing outside the platform without your agreement.
When 399w needs to share data with partners — payment processors for Pix transactions, KYC providers for document verification, security services for fraud detection — this is done under contracts with data protection clauses aligned with the LGPD. These partners receive only the minimum data necessary for their specific function and are contractually prohibited from using that data for any other purpose. 399w is responsible for ensuring its partners comply with these obligations.
Privacy is not a secondary concern at 399w — is a core pillar of the trust that underpins the relationship with every user.
