We explain clearly and directly how 57ein collects, uses, stores, and protects your personal data — in full compliance with the LGPD (Law No. 13.709/2018).
The 57ein is the Sports Betting and online casino platform responsible for processing the personal data of users registered at 57ein.net. Under the LGPD framework, the 57ein acts as controller — the entity that determines the purposes and means of personal data processing.
This Privacy Policy applies to all individuals who access, register for, or use the platform's services 57ein, including Sports Betting (football — Brasileirão Série A, Copa do Brasil, Libertadores —, MMA, UFC, basketball via NBB, volleyball, e-sports, and other sports), Live Casino games, slots, blackjack, poker, and all other available features.
For questions about this policy or about how your personal data is handled, please contact us at privacidade@57ein.net or through the support available at suporte@57ein.net.
In plain language: The 57ein is the entity that decides how your data is used and how it is protected. This policy explains all of that transparently, without unnecessary legal jargon.
The 57ein only collects data necessary to operate the platform, process transactions, and meet legal obligations. Below are the categories of data we collect and when each is obtained:
Data provided by you during registration:
Data collected during platform use:
Data collected for identity verification (KYC):
We do not collect: sensitive data such as racial origin, religious beliefs, health information, or sexual orientation. The 57ein has no interest in or operational need for that type of information.
The 57ein uses collected data solely for the purposes described below. No data is used for any purpose other than those stated here without your explicit consent:
The 57ein may send promotional emails about available bonuses and offers. You can unsubscribe from these communications at any time by clicking the unsubscribe link in any email or by contacting our support team.
The LGPD requires that every personal data processing operation have a specific legal basis. The 57ein bases the processing of your data on the following legal grounds, as set out in Article 7 of Law No. 13.709/2018:
| Legal Basis | Purpose at 57ein |
|---|---|
| Contract execution | Account operation, bet processing, deposits and withdrawals |
| Compliance with a legal obligation | KYC, anti-money laundering, compliance with regulatory authorities |
| Legitimate interest | Fraud prevention, platform security, anti-fraud monitoring |
| Consent | Sending promotional communications and email marketing |
When processing is based on consent — such as sending promotional emails — you have the right to withdraw that consent at any time, with no impact on your use of the platform. Withdrawing consent for marketing communications does not affect processing carried out under other legal bases, such as the execution of the usage contract for 57ein.
The 57ein does not sell, rent, or otherwise trade your personal data with third parties for advertising or marketing purposes. Data sharing occurs only in the specific situations described below, always for the purpose of operating the platform or fulfilling legal obligations:
In short: Your data is shared only with those who need it for the 57ein to function properly. Never for those looking to purchase a customer list or send unsolicited advertising.
The 57ein adopts technical and organizational measures to protect your personal data against unauthorized access, accidental loss, destruction, or improper disclosure. The key measures in place include:
No security system is entirely foolproof. In the event of a security incident affecting your personal data — such as an unauthorized access breach —, the 57ein will take the necessary containment measures and notify the affected data subjects and the ANPD (Autoridade Nacional de Proteção de Dados) in accordance with the timeframes and conditions established by the LGPD.
Data is stored on servers located in Brazil or in countries that offer a level of protection compatible with the LGPD, as detailed in Section 10.
The 57ein uses cookies and similar technologies to keep the platform running smoothly and to improve the user experience. Below we explain the types of cookies used and what each one does:
You can manage cookie preferences in your browser settings. Disabling non-essential cookies will not affect basic platform use, but may impact personalization features. Disabling strictly necessary cookies will prevent the 57ein.
Important note: The 57ein does not use third-party cookies for advertising tracking on other sites. Our cookies exist to make the platform work and to improve it — not to track you outside of 57ein.
The LGPD guarantees you, as the data subject whose personal data is processed by 57ein, the following rights. You may exercise them at any time by contacting us at privacidade@57ein.net:
Request a copy of all personal data that 57ein holds about you — in a readable, organized format.
Request the correction of incomplete, inaccurate or outdated data — such as your name, date of birth or registered address.
Request the deletion of data processed based on your consent. Data required by legal obligation (such as KYC) must be retained for the period required by law.
Receive your data in a structured, interoperable format for transfer to another controller, where technically feasible.
Object to processing based on legitimate interest or withdraw consent given for marketing communications at any time.
Know which entities the 57ein shared your data and for what reason — with full transparency regarding each recipient.
To exercise any of these rights, please contact us at privacidade@57ein.net identifying themselves with their full name and CPF. The 57ein will respond within a period of up to 15 business days, as provided under the LGPD. We may request additional documentation to verify your identity before processing the request — this verification is a security measure to prevent third parties from accessing your data.
If you believe your rights as a data subject are not being respected by 57ein, you have the right to file a complaint with the ANPD (National Data Protection Authority), pursuant to Article 55-J of the LGPD.
The 57ein retains your personal data only for as long as necessary for the purposes for which it was collected, respecting the minimum periods required by law. The main retention periods are as follows:
Once the applicable retention period expires, data is securely deleted or anonymized — making individual identification impossible — for statistical purposes.
The 57ein prioritizes storing data on servers located in Brazil. When data is transferred to infrastructure located in other countries — as may occur with certain cloud providers or technology services —, the 57ein ensures that such transfers occur only to countries or organizations that provide an adequate level of protection, in accordance with the criteria established by the ANPD.
In cases where the transfer takes place to countries without an adequacy decision from the ANPD, the 57ein adopts the safeguards set out in the LGPD — including standard contractual clauses and specific data protection commitments with the vendors involved.
In all cases, internationally transferred data remains subject to this Privacy Policy and the protections of the LGPD. You may request information about specific international transfers involving your data by emailing privacidade@57ein.net.
The 57ein is an adult entertainment platform restricted to users aged 18 and over. We do not knowingly collect personal data from minors. If we identify that an account was created or used by someone under 18, we will close the account immediately and delete the data collected, except where retention is required by legal obligation.
If you are the guardian of a minor and believe they may have created an account on 57ein, contact us immediately at suporte@57ein.net so that we can take the necessary steps.
Protection of minors: The 57ein applies age verification measures at registration — including CPF validation and, where required, document verification — specifically to prevent minors from accessing the platform.
The 57ein may update this Privacy Policy periodically to reflect changes in data processing practices, applicable legislation, or the services offered by the platform. The date of the most recent update is always shown at the top of this page.
Material changes — those that expand the scope of processing or reduce your rights as a data subject — will be communicated by email at least 7 days in advance before they take effect. Minor changes, such as text corrections or clarifications, may be published without prior notice.
We recommend you review this page periodically. Continued use of the platform 57ein after the effective date of an updated version constitutes acceptance of the new practices described. If you do not agree with the changes, you may request account closure by contacting support.
To exercise your rights as a data subject, clarify questions about this Privacy Policy, or report any concern related to the processing of your personal data by 57ein, use the channels below:
The 57ein maintains a Data Protection Officer (DPO) responsible for overseeing the platform's privacy practices and serving as the point of contact with the ANPD. The DPO can be reached by email at privacidade@57ein.net.
The response period for data subject rights requests is up to 15 business days from receipt of the complete request with verified identification. In more complex cases, this deadline may be extended, with prior notice and justification provided to the requester.
ANPD: If you believe that the 57ein did not adequately respond to a request regarding your personal data, you may contact the National Data Protection Authority directly through the gov.br/anpd portal.
Six concrete commitments that underpin every line of this policy
All data transmitted between your mobile device or computer and the servers of 57ein is encrypted with 256-bit SSL — the same standard used by banks in Brazil. Passwords are never stored in plain text: we use irreversible cryptographic hashing with an individual salt for each account.
The 57ein has adapted all its internal processes to comply with the requirements of the General Data Protection Law (Lei nº 13.709/2018) — from minimal data collection to the mechanisms that allow users to exercise their rights. This is not a differentiator; it is an obligation we take seriously.
The 57ein does not sell, rent, or share your data with advertisers or data brokers. Your data goes only to the necessary operational partners — such as Pix processors and game providers — and never to third-party advertising campaigns.
Within the 57ein, only employees who require certain data to carry out their role have access to it. Every access is recorded in audit logs. A support agent, for example, cannot see your full CPF or banking details — only what is necessary to resolve your request.
Access, correction, deletion, portability — these LGPD rights are real and enforceable at 57ein. Simply send an email to privacidade@57ein.net and our team will respond within 15 business days. We never leave requests unanswered or create obstacles to make exercising your rights difficult.
Emails about bonuses and promotions from 57ein are only sent with your consent. Every email includes a working unsubscribe link — one click and you stop receiving them. Essential account notifications (withdrawal confirmations, security alerts) are still sent regardless, as they are part of the terms of service.
