Our Privacy Commitments

Six principles guide how 31bd handles your personal information. Full details are provided in the numbered sections below.

1. Information We Collect

31bd collects personal information from you directly when you register, make a deposit, place a bet, or contact our support team. We also collect certain information automatically when you use the Platform. The categories of information we collect are set out below.

Registration and Identity Information

• Bangladesh mobile number used to create your account, receive OTP verification codes, and receive account notifications.
• Identity document details (national ID, passport, or other KYC documents) when required for account verification.
• A self-selected username and password (stored in hashed form — 31bd staff cannot view your plaintext password).

Financial and Transaction Information

• Deposit and withdrawal records, including amounts, dates, and the payment method used (bKash, Nagad, Rocket, or Upay account reference).
• Betting history, including markets wagered on, stake amounts, odds accepted, and results.
• Bonus and promotion redemption records.

Technical and Usage Information

• IP address, device type, operating system, and browser type collected each time you access the Platform.
• Session data including login timestamps, pages visited, game sessions, and actions taken within the Platform.
• Cookie and local storage identifiers used to maintain your session and remember your preferences.

2. How We Use Your Information

31bd uses the personal information we collect for the following purposes. We do not use your information for any purpose not listed here without first obtaining your explicit consent.

• To create, operate, and maintain your 31bd account, including verifying your identity and age during the KYC process.
• To process deposits and withdrawals via bKash, Nagad, Rocket, Upay and other supported payment methods, and to maintain accurate financial records of all transactions.
• To detect and prevent fraud, money laundering, bonus abuse, and other prohibited conduct as defined in the 31bd Terms and Conditions.
• To provide customer support and respond to your queries, complaints, and disputes in a timely and accurate manner.
• To personalise your experience on the Platform, including surfacing betting markets, game recommendations, and promotional offers that are relevant to your activity.
• To comply with applicable legal obligations, including record-keeping requirements and cooperation with law enforcement authorities where required by applicable law.

3. Legal Basis for Processing

31bd processes your personal data on one or more of the following legal bases, depending on the specific processing activity and applicable law.

• Contractual necessity — processing required to perform the contract between you and 31bd, for example creating your account, processing bets, and handling deposits and withdrawals.
• Legal obligation — processing required to comply with applicable laws, including anti-money laundering obligations, KYC requirements, and cooperation with regulatory authorities.
• Legitimate interests — processing carried out for 31bd's legitimate business interests, such as fraud prevention, Platform security, and service improvement, where those interests are not overridden by your rights.
• Consent — where 31bd processes your personal data for marketing or promotional communications, we will do so only where you have given clear, affirmative consent. You may withdraw that consent at any time by contacting support.

4. Sharing Your Information

31bd does not sell, rent, or trade your personal data. We share personal information with third parties only in the following limited circumstances.

• Payment processors — we share transaction reference data with bKash, Nagad, Rocket, and Upay to facilitate deposits and withdrawals. These providers operate under their own privacy policies and are bound by their respective regulatory obligations.
• Game providers — game session data may be shared with providers such as Pragmatic Play, Evolution Gaming, Ezugi, and Spribe to operate their games on the 31bd Platform. These providers receive only the data necessary for game delivery.
• Legal and regulatory authorities — we may be required to disclose your personal data to law enforcement, regulatory bodies, or courts when required to do so by applicable law or a valid legal order.
• Fraud prevention and security services — anonymised or pseudonymised transaction data may be shared with fraud detection services to protect the Platform and its users from fraudulent activity.

All third parties who receive personal data from 31bd are required to process that data only for the purpose for which it was shared, to maintain appropriate security measures, and to comply with applicable data protection laws.

5. Payment Data

When you make a deposit or request a withdrawal on the 31bd Platform, your transaction is processed via your selected mobile financial service (bKash, Nagad, Rocket, or Upay). 31bd does not store your mobile banking PIN, bKash wallet PIN, or any authentication credentials for these services. We record only the transaction reference number, the amount, the date, and the mobile number associated with your payment account, for the purposes of reconciliation and dispute resolution.

Your payment account details are used solely to execute and record transactions. 31bd does not use your payment details for any marketing purpose and does not share them with third parties except as described in Section 4 of this policy.

6. Data Retention

31bd retains your personal data for as long as your account is active and for a defined period after account closure. The standard retention period for closed account data is five years from the date of account closure, after which personal data is securely deleted or anonymised. This retention period reflects 31bd's obligations to maintain financial records for compliance and audit purposes.

In certain circumstances — for example where an account is under investigation for suspected fraud or where a legal hold is in place — personal data may be retained for longer than the standard period. 31bd will inform you if your data is being retained beyond the standard period for such reasons, to the extent permitted by applicable law.

7. Cookies and Tracking Technologies

The 31bd Platform uses cookies and similar local storage technologies to operate certain features of the site and to improve your experience. The types of cookies we use are as follows.

• Essential cookies — required for the Platform to function correctly, including session management (keeping you logged in) and security tokens. These cookies cannot be disabled without preventing you from using the Platform.
• Analytics cookies — used to understand how players navigate and use the Platform, enabling 31bd to improve site performance and user experience. Analytics data is aggregated and does not identify individual users.
• Preference cookies — used to remember your language preference and other personalisation settings so that you do not have to re-enter them each visit.

You may disable non-essential cookies through your mobile browser's settings. Please note that disabling essential cookies will impair the functionality of the 31bd Platform and may prevent you from logging in or completing transactions.

8. Your Privacy Rights

As a registered 31bd member, you have the following rights in relation to your personal data. To exercise any of these rights, contact 31bd support at [email protected]. We will respond to all valid requests within 30 days.

• Right of access — you may request a copy of the personal data that 31bd holds about you.
• Right to rectification — if you believe that any personal data we hold about you is inaccurate or incomplete, you may request that we correct or update it.
• Right to erasure — you may request deletion of your personal data, subject to any legal or regulatory retention obligations that prevent us from complying immediately.
• Right to restrict processing — you may request that we restrict the processing of your personal data in certain circumstances, for example while a complaint or correction request is being investigated.
• Right to withdraw consent — where processing is based on your consent, you may withdraw that consent at any time. Withdrawal of consent does not affect the lawfulness of processing carried out before withdrawal.

31bd will not discriminate against you for exercising any of your privacy rights. If you are dissatisfied with our response to a privacy request, you may escalate your complaint by contacting our support team directly at [email protected].

9. Security

31bd implements industry-standard technical and organisational security measures to protect your personal data against unauthorised access, disclosure, alteration, or destruction. These measures include 256-bit SSL encryption for all data transmitted between your device and the 31bd Platform, password hashing using modern cryptographic algorithms, restricted access controls limiting staff access to personal data on a need-to-know basis, and regular security reviews of the Platform's infrastructure.

No method of electronic transmission or storage is completely secure. While 31bd takes reasonable steps to protect your personal data, we cannot guarantee absolute security. If you suspect that your account has been compromised, please contact support immediately at [email protected].

10. Minors

The 31bd Platform is strictly for adults aged 21 and above. We do not knowingly collect personal data from any person under the age of 21. If 31bd becomes aware that personal data has been collected from a minor, we will immediately close the relevant account and delete all associated personal data. If you believe that a minor has registered on the 31bd Platform, please contact us at [email protected] so that we can take prompt action.

11. Changes to This Privacy Policy

31bd may update this Privacy Policy from time to time to reflect changes in our practices, applicable law, or the features of the Platform. When we make material changes, we will display a notice on the Platform and update the "Last Updated" date at the top of this page. We encourage you to review this Privacy Policy periodically. Continued use of the 31bd Platform after any update constitutes your acceptance of the revised policy.
