Privacy Policy —
51bd Data Protection Commitment
At 51bd, your privacy is not an afterthought — it is a foundational part of how we operate. This Privacy Policy explains precisely what personal data we collect when you use the 51bd platform, why we collect it, how it is stored and protected, who it may be shared with, and what rights you hold over your own information. We encourage you to read this document carefully alongside our Terms & Conditions.
Our Privacy Principles
Six core commitments that define how 51bd handles your personal information. The full legal detail for each principle follows in the policy sections below.
Minimal Data Collection
51bd collects only the personal data that is strictly necessary for account registration, identity verification, payment processing, and the delivery of platform services. We do not collect data speculatively or in excess of what each specific purpose requires.
No Third-Party Data Sales
Your personal data is never sold, rented, or traded to third-party marketers or advertisers under any circumstances. Data sharing with third parties is strictly limited to service providers who are contractually obligated to handle your information in compliance with this Privacy Policy.
SSL Encryption & Secure Storage
All data transmitted between your device and the 51bd platform is protected by industry-standard SSL/TLS encryption. Stored personal data is held in secured environments with access controls, audit logging, and regular security reviews to prevent unauthorised access or disclosure.
Your Rights Are Respected
Every registered player at 51bd has the right to access, correct, or request deletion of their personal data. You may also request a copy of the data we hold about you, object to certain types of processing, or restrict how your data is used by contacting our support team at any time.
Defined Retention Periods
51bd does not retain personal data indefinitely. Retention periods are set according to the purpose for which data was collected and any applicable legal obligations. Account data is retained for as long as your account remains active; data may be retained beyond account closure where required by law or for fraud prevention purposes.
Breach Notification
In the event of a data breach that is likely to result in a risk to your rights, 51bd is committed to notifying affected players promptly via their registered email address. We will provide clear information about the nature of the breach, the data involved, and the steps we are taking to mitigate any potential harm.

01 Introduction
51bd operates as a safe and reliable online betting and casino platform serving players in Bangladesh. We are committed to protecting the privacy and personal data of every individual who interacts with the 51bd platform, whether through the website at 51bd.io, through any associated mobile interface, or through our customer support channels.
This Privacy Policy describes in plain, formal English what personal information 51bd collects about you, the legal basis on which it is processed, how it is stored and protected, the circumstances in which it may be shared, how long it is retained, and the rights you have in relation to your own data. It should be read together with the 51bd Terms & Conditions and the Responsible Gaming policy, both of which are incorporated by reference.
51bd takes its data protection responsibilities seriously. We apply appropriate technical and organisational measures to safeguard personal data and we do not use your information for any purpose beyond those described in this Policy without your explicit consent.
02 Data Controller
For the purposes of this Privacy Policy, 51bd acts as the data controller in respect of all personal data collected from players accessing the platform at 51bd.io. As data controller, 51bd determines the purposes for which and the means by which personal data is processed.
All data protection enquiries, subject access requests, deletion requests, and objections to processing should be directed in writing to the 51bd Data Protection contact at: [email protected]
When contacting us regarding a data protection matter, please include your registered account username and a clear description of your request. We will acknowledge your enquiry within 5 business days and aim to provide a substantive response within 30 calendar days.

04 How We Collect Your Data
51bd collects personal data through the following channels:
4.1 Directly From You
The majority of personal data we hold is provided directly by you during the account registration process, when completing KYC verification, when making deposits or withdrawals, when contacting customer support, or when opting in to promotional offers. You control what information you provide through these interactions.
4.2 Automatically During Platform Use
When you access and use the 51bd platform, certain technical data is collected automatically through our server infrastructure and analytics tools. This includes your IP address, device specifications, browser type, session duration, pages visited, and in-game activity logs. This data is collected to ensure platform security, detect fraud, and improve the user experience.
4.3 From Payment Providers
When you make a deposit or request a withdrawal using bKash, Nagad, Rocket, Upay, or a bank transfer, our payment processing partners may share transaction confirmation data with 51bd, including the sender's registered mobile number, transaction reference ID, and transfer amount. This data is used solely to credit your 51bd account and maintain accurate financial records.
4.4 From Third-Party Game Providers
Live casino and slot game studios — including Evolution Gaming, Pragmatic Play, Ezugi, NetEnt, and Microgaming — may pass game session data back to 51bd's systems for the purposes of settling bets, resolving disputes, and maintaining audit logs. This data is limited to game outcomes, session identifiers, and wagered amounts; game providers do not share broader personal profile data with 51bd.
05 Purposes and Legal Basis for Processing
51bd processes personal data only for specified, explicit, and legitimate purposes. The table below summarises the primary purposes for which we process your data and the legal basis that justifies each type of processing.

| Account creation and management | Registration data | Contract performance |

Legitimate Interest: Where 51bd relies on "legitimate interest" as its legal basis, we have assessed that our interests in processing your data do not override your fundamental rights and freedoms. You may object to processing carried out on the basis of legitimate interest by contacting [email protected].
06 Cookies and Tracking Technologies
6.1 What Are Cookies
Cookies are small text files that are stored on your device when you visit a website. 51bd uses cookies and similar tracking technologies — including session tokens and local storage — to enable the platform to function correctly, to remember your preferences, to keep your session secure, and to gather anonymised analytical data about how players interact with the platform.
6.2 Types of Cookies Used
- Strictly Necessary Cookies: Required for the platform to operate. These include session authentication tokens, security cookies, and load balancing cookies. These cannot be disabled.
- Functional Cookies: Used to remember your language preferences, display settings, and last-used payment method to improve your experience on return visits.
- Analytical Cookies: Used to collect anonymised data about how players navigate the platform — such as pages visited, session duration, and feature usage — to help us improve platform design and performance.
- Fraud Prevention Cookies: Used to detect and prevent fraudulent activity, including the use of multiple accounts, by creating a device fingerprint linked to your account session.
6.3 Managing Cookies
You may manage or disable non-essential cookies through your browser settings. Please note that disabling functional or analytical cookies may affect your experience of the platform. Strictly necessary cookies cannot be disabled without preventing core platform functionality from working correctly.
Third-Party Cookies: Some game provider studios embedded within the 51bd platform (such as Evolution Gaming and Pragmatic Play) may set their own cookies as part of their game delivery infrastructure. These cookies are subject to the respective studios' own privacy policies and are outside 51bd's direct control.
07 Data Sharing and Disclosure
51bd does not sell your personal data to any third party. We may share your personal data with third parties only in the specific circumstances described below, and only to the extent necessary for the stated purpose.
7.1 Payment Service Providers
To process deposits and withdrawals, 51bd shares necessary transaction data with your chosen payment provider (bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, Islami Bank, or Sonali Bank). This is limited to the data required to complete the transaction and is governed by the payment provider's own terms and privacy policy.
7.2 Identity Verification Partners
Where 51bd uses a third-party KYC service provider to assist with identity verification, your identity documents and verification images may be shared with that provider. All KYC partners are contractually required to process this data only for verification purposes and to delete it following completion of the verification process.
7.3 Game Studio Providers
To deliver live casino, slot, and other gaming content, 51bd integrates with licensed third-party game studios. These studios may receive session identifiers and account reference codes (but not your full personal profile) necessary to initiate and settle game sessions. All studio integrations are subject to data processing agreements.
7.4 Legal and Regulatory Disclosure
51bd may be required to disclose personal data to law enforcement agencies, courts, or regulatory authorities where we receive a valid legal request or are under a legal obligation to do so. In such cases, we will disclose only the minimum data required to comply with the applicable legal obligation.
7.5 Fraud Prevention and Security
Where we detect or suspect fraud, money laundering, or other illegal activity, we may share relevant account data with specialist fraud prevention agencies, other betting platforms operating shared security intelligence programmes, or relevant authorities. This sharing is carried out on the basis of our legitimate interests and legal obligations.
7.6 Business Transfers
In the event of a merger, acquisition, or transfer of all or substantially all of 51bd's assets, player data may be transferred to the acquiring entity as part of that transaction. In such circumstances, 51bd will take reasonable steps to ensure that player data continues to be protected in a manner consistent with this Privacy Policy and will notify affected players via their registered email address prior to any such transfer taking effect.
08 International Data Transfers
The 51bd platform primarily serves players in Bangladesh. However, some of the third-party service providers we work with — including game studio providers and cloud infrastructure partners — may process or store data in data centres located outside Bangladesh. Where such international transfers take place, 51bd ensures that adequate safeguards are in place to protect your data, including contractual data processing agreements that impose data protection obligations equivalent to those described in this Policy.
If you have questions about the safeguards in place for any specific international data transfer involving your personal data, please contact us at [email protected].
09 Data Retention
51bd retains personal data only for as long as is necessary to fulfil the purpose for which it was collected, or as required by applicable law. The retention periods below apply as general guidelines:
| Data Category | Retention Period | Reason |
|---|---|---|
| Account registration data | Duration of account + 5 years post-closure | Legal obligation; dispute resolution |
| KYC identity documents | Duration of account + 5 years post-closure | Anti-money laundering compliance |
| Transaction and financial records | 7 years from transaction date | Financial record-keeping requirements |
| Betting and gaming activity logs | 3 years from session date | Dispute resolution; responsible gambling monitoring |
| Customer support communications | 3 years from last communication | Complaint records; quality assurance |
| Technical / device / IP data | 12 months from collection | Security and fraud prevention |
| Marketing consent records | Until consent is withdrawn + 1 year | Evidence of consent |
Where retention beyond these periods is required by a specific legal obligation or an ongoing investigation, 51bd will retain the relevant data until that obligation or investigation is resolved. Data that is no longer required is securely deleted or anonymised.
10 Security Measures
51bd implements a range of technical and organisational security measures to protect your personal data against unauthorised access, loss, alteration, or disclosure. These measures include, but are not limited to:
- SSL/TLS Encryption: All data transmitted between your device and 51bd's servers is encrypted using industry-standard TLS protocols.
- Encrypted Password Storage: Account passwords are never stored in plain text. They are hashed using a strong cryptographic algorithm with individual salting.
- Access Controls: Access to systems containing personal data is restricted to authorised 51bd personnel on a strict need-to-know basis. All access is logged and regularly audited.
- Infrastructure Security: 51bd's server infrastructure is hosted in secured data centres with physical access controls, redundant power systems, and network-level firewall protections.
- Regular Security Reviews: 51bd conducts periodic internal security assessments and works with third-party security specialists to identify and address vulnerabilities.
- Incident Response Plan: 51bd maintains a documented data breach response plan that includes containment procedures, impact assessment protocols, and player notification processes.
Player Responsibility: While 51bd implements robust security measures on the platform side, you are responsible for maintaining the security of your own account credentials. Use a strong, unique password for your 51bd account, do not share your login details with any third party, and contact [email protected] immediately if you suspect unauthorised access to your account.
11 Your Data Protection Rights
As a registered player at 51bd, you have the following rights in relation to your personal data. To exercise any of these rights, please contact [email protected] with your verified account details and a clear description of your request.

Right to Erasure
You may request the deletion of your personal data where it is no longer necessary for the purposes for which it was collected, where you withdraw consent (and no other legal basis applies), or where processing is unlawful. Note that erasure requests may be limited where 51bd is required by law to retain certain data (for example, financial transaction records).
Right to Restriction of Processing
You may request that 51bd restricts the processing of your personal data in certain circumstances — for example, while the accuracy of data you have contested is being verified, or while an objection to processing is being assessed.
Right to Data Portability
Where processing is based on your consent or on a contract, and is carried out by automated means, you have the right to receive a copy of your personal data in a structured, commonly used, and machine-readable format, and to request that it be transmitted to another controller where technically feasible.
Right to Object
You have the right to object at any time to the processing of your personal data where that processing is based on 51bd's legitimate interests. You also have an unconditional right to object to your data being processed for direct marketing purposes, including profiling related to direct marketing.

Where processing is based on your consent, you may withdraw that consent at any time without affecting the lawfulness of processing carried out prior to the withdrawal. To withdraw consent to marketing communications, use the unsubscribe link in any marketing email or contact [email protected] directly.
How to Exercise Your Rights: Submit all data rights requests to [email protected] with the subject line "Data Rights Request". Include your registered account username and, for security purposes, a brief description that allows us to verify your identity before actioning the request. We will respond within 30 calendar days. Complex requests may require up to an additional 60 days, in which case we will notify you of the extension and the reason for it.
12 Children and Minors
The 51bd platform is strictly intended for adults aged 21 and above. We do not knowingly collect personal data from any individual below the age of 21. Age verification is a mandatory step in the account registration process, and 51bd reserves the right to request documentary proof of age at any time.
If 51bd discovers or is notified that personal data has been collected from an individual below the minimum age of 21, we will immediately suspend the relevant account, delete all associated personal data, and reverse any financial transactions where technically possible. If you believe that a minor has registered an account on the 51bd platform, please report this to [email protected] immediately.
Parents and guardians are encouraged to make use of internet filtering tools to prevent minors from accessing online gambling platforms. Further guidance is available on the Responsible Gaming page.
13 Marketing Communications
51bd may send you promotional communications — including bonus offers, tournament announcements, seasonal promotions (such as Eid specials, Pohela Boishakh offers, and BPL season promotions), and platform updates — where you have given your explicit consent to receive such communications at the time of account registration or subsequently.
13.1 Opt-In
Marketing communications are sent only to players who have affirmatively opted in during the registration process or who have subsequently subscribed via their account settings or by contacting support. Consent is recorded with a timestamp and the channel through which it was given.

You may withdraw your consent to receive marketing communications at any time by:
- Clicking the unsubscribe link in any marketing email sent by 51bd;
- Contacting 51bd support at [email protected] with the subject line "Unsubscribe";
- Updating your communication preferences in your account settings.
Unsubscribe requests will be processed within 5 business days. Please note that opting out of marketing communications does not affect transactional communications (such as deposit confirmations, withdrawal notifications, security alerts, and account verification messages), which are sent as a necessary part of providing the platform service.
13.3 No Third-Party Marketing
51bd does not share your personal data with third-party marketers for the purpose of sending you marketing communications on their behalf. All marketing communications you receive from 51bd relate solely to 51bd platform products and promotions.

The notification will summarise the key changes and direct you to the updated Policy.
Your continued use of the 51bd platform following the effective date of any amended Privacy Policy constitutes your acceptance of the updated terms. If you do not agree to the amended Policy, you should cease using the platform and may request account closure by contacting [email protected].
