51bd Privacy Policy — How We Handle Your Data

This Privacy Policy ("Policy") applies to all users of the 51bd website and platform, including players based in Dhaka, Chittagong, Sylhet, Rajshahi, Barisal, Rangpur, Khulna, Mymensingh, Cox's Bazar, and all other locations in Bangladesh and South Asia. By registering an account or using any part of the 51bd platform, you acknowledge that you have read and understood this Policy and consent to the collection, processing, and use of your personal data as described herein. If you do not agree with this Policy, please do not use the 51bd platform.

51bd collects personal information from you in three primary ways: information you provide directly during registration and account use; information generated automatically by your use of the platform; and information received from third-party payment providers when you make deposits or withdrawals. The specific data collected under each category is described below.

51bd uses the personal data we collect for the following purposes. We will not use your data for any purpose not listed here without first obtaining your explicit consent:

• Account creation, verification, and ongoing management — including KYC compliance, age verification (21+ requirement), and account security.
• Processing deposits and withdrawals via bKash, Nagad, Rocket, Upay, and INR payment channels — including reconciling transaction records and resolving payment disputes.
• Delivering the platform's betting and casino services — including presenting relevant game recommendations, live odds for BPL, IPL, T20 World Cup and other cricket markets, and personalised promotional offers where you have opted in.
• Fraud detection and prevention — including identifying suspicious account activity, chargebacks, multiple account registration, and bot usage, and sharing relevant data with payment providers where legally required.
• Customer support — to respond to your queries, complaints, responsible gaming requests, or technical issues submitted via email to [email protected].
• Legal and regulatory compliance — including retaining records as required by applicable law, responding to lawful requests from competent authorities, and enforcing our Terms & Conditions.

51bd does not use your personal data for automated profiling that produces legal or similarly significant effects without human review. Our game recommendation engine uses aggregated behavioural data to surface titles you may enjoy, but this does not affect your account standing or access rights in any way.

51bd takes the security of payment-related data extremely seriously. When you make a deposit via bKash, Nagad, Rocket, or Upay, 51bd receives only the confirmation data necessary to credit your account — we do not store your full mobile wallet credentials or PIN. Partial wallet numbers (e.g., the last four digits of your bKash number) may be retained in transaction logs for dispute resolution and fraud prevention purposes. These logs are encrypted at rest and accessible only to authorised 51bd staff on a need-to-know basis.

For INR deposits, 51bd applies equivalent data handling standards. Currency conversion is performed at the time of transaction using the prevailing exchange rate, and the converted BDT equivalent is reflected in your 51bd account balance. 51bd does not retain your full INR account number or UPI ID beyond what is required for transaction verification. All payment data is purged or anonymised in accordance with our data retention schedule set out in Section 6 of this Policy.

51bd uses cookies and similar tracking technologies to operate and improve the platform. Cookies are small text files stored on your device that help us keep your session active, remember your preferences, and gather anonymised analytics about how players use the site.

We use three categories of cookies: (1) Strictly necessary cookies — required for the platform to function (e.g., session authentication, CSRF protection). These cannot be disabled. (2) Functional cookies — used to remember your language preference and display settings. (3) Analytics cookies — used to understand aggregated usage patterns so we can improve the platform experience for Bangladesh players. Analytics cookies do not identify you personally.

51bd does not sell your personal data. We share your information only in the following limited circumstances, and only to the minimum extent necessary:

• Payment providers — We share transaction reference data with bKash, Nagad, Rocket, Upay, and INR payment processors solely to complete deposit and withdrawal processing and to resolve payment disputes.
• Game and platform providers — Anonymised behavioural data (e.g., which game types are most played by Bangladesh users) may be shared with game studios such as Pragmatic Play, Evolution Gaming, and Spribe to improve game performance and inform content development. This data does not include your name, mobile number, or financial details.
• Legal and regulatory authorities — 51bd may disclose your data to law enforcement, regulatory bodies, or other competent authorities where required to do so by applicable law, court order, or where 51bd has a legitimate interest in preventing fraud or protecting the safety of its users.
• Business transfers — In the unlikely event of a merger, acquisition, or sale of all or substantially all of 51bd's assets, your personal data may be transferred to the successor entity. You will be notified of any such transfer via the email or mobile number registered to your account before the transfer takes effect.

In all cases where 51bd shares data with third parties, we require those parties to maintain appropriate technical and organisational security measures and to use the data only for the purposes for which it was shared. 51bd remains accountable for the data shared under this Policy.

51bd retains your personal data for as long as your account is active and for such period thereafter as is required or permitted by applicable law. Specifically: account registration data and KYC documentation are retained for the duration of your account plus a minimum of five years after account closure, in line with standard anti-money laundering record-keeping obligations. Transaction records (deposit and withdrawal history) are retained for a minimum of five years from the date of each transaction. Support correspondence is retained for two years from the date of each interaction.

After the applicable retention period, personal data is securely deleted or anonymised so that it can no longer be linked to you as an individual. Where data is anonymised rather than deleted, the anonymised data may be retained indefinitely for statistical and product improvement purposes. Players may request early deletion of their personal data by contacting [email protected], subject to 51bd's legal obligation to retain certain records as described above.

As a 51bd player, you have the following rights in relation to your personal data. To exercise any of these rights, please contact [email protected] with the subject line "Privacy Rights Request":

• Right of access — You may request a copy of all personal data 51bd holds about you. We will provide this within 30 days of receiving your verified request.
• Right of rectification — If any personal data we hold about you is inaccurate or incomplete, you may request that we correct or complete it. Account details (name, mobile number) can also be updated by contacting support directly.
• Right of erasure — You may request deletion of your personal data where it is no longer necessary for the purposes for which it was collected, subject to 51bd's legal retention obligations described in Section 6.
• Right to restrict processing — In certain circumstances (e.g., where you contest the accuracy of data we hold), you may request that we restrict how we use your personal data while the matter is resolved.
• Right to object to marketing — If you have opted in to receive promotional communications from 51bd, you may withdraw that consent at any time by contacting [email protected]. Withdrawal of consent does not affect the lawfulness of processing carried out before your withdrawal.

51bd will acknowledge all privacy rights requests within 5 business days and aim to resolve them fully within 30 days. Where a request is particularly complex or we have received a high volume of requests, we may extend this period by a further 30 days and will notify you accordingly. There is no charge for submitting a privacy rights request.

51bd employs a range of technical and organisational security measures to protect your personal data from unauthorised access, disclosure, alteration, or destruction. These include: 256-bit SSL/TLS encryption on all data in transit; AES-256 encryption for sensitive data stored at rest; role-based access controls ensuring that only authorised 51bd personnel can access player data; regular security audits and penetration testing; multi-factor authentication for internal administrative systems; and automated anomaly detection to identify and respond to unusual access patterns in real time.

While 51bd takes all reasonable steps to protect your personal data, no online platform can guarantee absolute security. In the event of a data breach that is likely to result in a high risk to your rights and freedoms, 51bd will notify affected players as soon as practicable and will take all necessary steps to mitigate the impact of the breach. If you suspect that your 51bd account has been compromised, please contact [email protected] immediately.

The 51bd platform is strictly intended for adults aged 21 and above. We do not knowingly collect personal data from any person under the age of 21. If we become aware that we have inadvertently collected personal data from a minor, we will take immediate steps to delete that data and close the associated account. If you are a parent or guardian and believe that a person under 21 has registered a 51bd account using your or their personal details, please contact [email protected] immediately with the subject line "Underage Account Report". We treat all such reports as a top priority and will investigate and act within 24 hours.

51bd may update this Privacy Policy from time to time to reflect changes in our data practices, platform features, or applicable law. When we make material changes — such as changes to the categories of data we collect, the purposes for which we use it, or the third parties we share it with — we will notify registered players via the mobile number or email address on their account at least 14 days before the changes take effect. The updated Policy will always be available at 51bd.ws/privacy-policy. The date at the top of this Policy indicates when it was last revised. Your continued use of the 51bd platform after the effective date of any update constitutes your acceptance of the revised Policy.
