3 Personal Data We Collect

bk664 collects personal data in three principal ways: data you provide directly, data generated automatically through your use of the Platform, and data received from third-party service providers. The following table summarises the categories of personal data we collect and the primary source of each category.

bk664 does not collect special categories of sensitive personal data (such as racial or ethnic origin, political opinions, religious beliefs, health data, or biometric data) except where strictly required by applicable law or where you have provided such data voluntarily in the context of a responsible gaming self-assessment.

4 How We Use Your Personal Data

bk664 uses the personal data we collect for the following specific purposes:

1. Account Management: To create, maintain, and manage your registered account, including verifying your identity and age (21+), processing password resets, and communicating account-related notifications;
2. Service Delivery: To provide access to the betting and casino services available on the Platform, settle bets, credit winnings, and maintain accurate records of your wagering activity;
3. Payment Processing: To facilitate deposits and withdrawals in BDT via bKash, Nagad, Rocket, and Upay, and to maintain a complete and accurate transaction history for your account;
4. Identity & Age Verification (KYC): To verify that you meet the minimum age requirement of 21 years and to satisfy anti-money laundering (AML) obligations by confirming your identity through document review;
5. Fraud Prevention & Security: To detect, investigate, and prevent fraudulent activity, money laundering, multi-accounting, bonus abuse, and other forms of prohibited conduct as defined in our Terms & Conditions;
6. Customer Support: To respond to your enquiries, resolve disputes, and provide assistance through our 24/7 English-language support team;
7. Platform Improvement: To analyse usage patterns, identify technical issues, conduct A/B testing, and improve the performance, security, and user experience of the Platform;
8. Responsible Gaming: To monitor your account activity for indicators of problem gambling and, where appropriate, to prompt you to use responsible gaming tools such as deposit limits and self-exclusion;
9. Legal & Regulatory Compliance: To comply with applicable laws, regulations, court orders, and legitimate requests from competent authorities;
10. Marketing Communications (opt-in only): To send you promotional offers, bonus notifications, and news about bk664 services, but only where you have expressly opted in to receive such communications. You may withdraw consent at any time.

5 Legal Basis for Processing

bk664 processes your personal data on one or more of the following legal bases, depending on the specific purpose of the processing activity:

• Contractual Necessity: Processing is necessary to perform our contractual obligations to you under the Terms & Conditions — for example, to create and manage your account, process deposits and withdrawals, and settle bets;
• Legal Obligation: Processing is required to comply with a legal or regulatory obligation applicable to bk664 — for example, KYC identity verification and AML transaction monitoring;
• Legitimate Interests: Processing is necessary for the purposes of bk664's legitimate business interests, provided those interests are not overridden by your rights and interests — for example, fraud detection, platform security, and product improvement;
• Consent: Where processing is based on your freely given, specific, informed, and unambiguous consent — for example, the sending of marketing and promotional communications. You may withdraw consent at any time by contacting [email protected].

6 Sharing of Personal Data

bk664 does not sell your personal data. We share your personal data only in the circumstances set out below, and only to the extent necessary for the specified purpose:

1. Payment Service Providers: We share financial data with bKash, Nagad, Rocket, and Upay solely to process your deposit and withdrawal transactions in BDT. These providers process your data under their own privacy policies and are responsible for the security of data within their own systems;
2. Identity Verification Partners: We may share identity documents and personal details with third-party KYC verification service providers for the purpose of confirming your identity and age in accordance with applicable AML requirements;
3. Game Technology Providers: Technical usage data may be shared with our casino game technology partners — including Evolution Gaming, Ezugi, Pragmatic Play, Spribe, Microgaming, and NetEnt — to the extent necessary to deliver game functionality and resolve technical disputes;
4. Fraud & Security Service Providers: We work with specialist third-party providers to assist with fraud detection, risk assessment, and platform security. These providers process data on our behalf under strict data processing agreements;
5. Legal & Regulatory Authorities: We may disclose personal data to law enforcement agencies, regulatory bodies, or courts where required to do so by applicable law, a court order, or a legitimate legal process;
6. Business Transfers: In the event of a merger, acquisition, restructuring, or sale of all or part of bk664's business assets, personal data held by bk664 may be transferred to the acquiring entity, subject to equivalent data protection obligations.

7 Cookies & Tracking Technologies

bk664 uses cookies and similar tracking technologies to operate the Platform effectively, remember your preferences, analyse usage patterns, and support fraud detection. The following categories of cookies are used on the Platform:

• Strictly Necessary Cookies: These cookies are essential for the Platform to function. They enable core features such as user authentication, session management, and security. These cookies cannot be disabled without disrupting Platform functionality;
• Performance & Analytics Cookies: These cookies collect anonymised or aggregated information about how users interact with the Platform — such as pages visited, time spent, and error messages encountered — to help us improve performance and identify technical issues;
• Functional Cookies: These cookies remember your preferences and settings — such as language preference and display options — to personalise your experience on return visits;
• Fraud Detection Cookies: These cookies assist our security systems in identifying unusual patterns of behaviour that may indicate fraudulent activity, multi-accounting, or the use of automated tools on the Platform.

You may manage cookie preferences through your browser settings. Please note that disabling strictly necessary cookies will impair your ability to use the Platform, including your ability to log in and place bets. Disabling other categories of cookies will not prevent you from using the Platform but may affect your experience.

8 Data Retention

bk664 retains personal data for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable law. The following general retention periods apply:

Upon expiry of the applicable retention period, personal data is securely deleted or anonymised in a manner that prevents reconstruction of the original data. Where data is anonymised rather than deleted, the anonymised data may be retained indefinitely for statistical and analytical purposes.

9 Data Security

bk664 implements a comprehensive set of technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, alteration, or disclosure. These measures include, but are not limited to:

• 256-bit SSL/TLS encryption for all data in transit between your device and our servers;
• Encryption of sensitive data fields at rest within our database infrastructure;
• Strict role-based access controls limiting internal access to personal data to authorised personnel with a legitimate operational need;
• Regular security assessments, penetration testing, and vulnerability scanning of the Platform;
• Comprehensive audit logging of all access to personal data by internal systems and staff;
• Formal incident response procedures to detect, contain, and notify affected parties in the event of a data breach.

While bk664 takes all reasonable steps to protect your personal data, no system of security is completely impenetrable. In the event of a data breach that is likely to result in a risk to your rights and freedoms, bk664 will notify affected users without undue delay at the email address registered on their account.

10 Your Rights

As a user of the bk664 Platform, you have the following rights in respect of your personal data. To exercise any of these rights, please submit a written request to [email protected]. bk664 will respond to all verified requests within 30 calendar days:

2. Right to Rectification: You have the right to request that inaccurate or incomplete personal data held about you be corrected or completed without undue delay;
3. Right to Erasure: In certain circumstances, you have the right to request that your personal data be deleted — for example, where the data is no longer necessary for the purpose for which it was collected. This right is subject to overriding legal obligations such as AML data retention requirements;
4. Right to Restriction of Processing: You have the right to request that processing of your personal data be restricted in certain circumstances — for example, while the accuracy of data you have contested is being verified;
5. Right to Data Portability: Where processing is based on your consent or on contractual necessity and is carried out by automated means, you have the right to receive your personal data in a structured, commonly used, machine-readable format;
6. Right to Object: You have the right to object to processing of your personal data where that processing is based on legitimate interests, including profiling. You also have an absolute right to object to processing for direct marketing purposes;
7. Right to Withdraw Consent: Where processing is based on your consent, you have the right to withdraw that consent at any time. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

11 Marketing Communications

bk664 sends marketing and promotional communications — including bonus offers, game launch announcements, and seasonal promotions — only to users who have expressly opted in to receive such communications during account registration or at a subsequent point through their account settings.

You may withdraw your consent to receive marketing communications from bk664 at any time by:

• Clicking the "unsubscribe" link included in any marketing email you receive from bk664;
• Updating your communication preferences in your account settings; or
• Submitting a written request to [email protected].

Please allow up to 5 business days for opt-out requests to take effect across all communication channels. Withdrawal of marketing consent does not affect the sending of transactional and account-related communications that are necessary for the operation of your account, such as deposit confirmations, withdrawal notifications, and security alerts.

12 Children & Minors

If you are a parent or guardian and believe that a person under 21 in your care has registered an account with bk664, please contact our support team immediately at [email protected]. We will investigate the matter and take appropriate action without delay, including the return of any deposited funds to the payment source.

bk664 strongly encourages parents and guardians to use parental control software to prevent underage individuals from accessing online gambling platforms.

13 Changes to This Policy

bk664 reserves the right to update or modify this Privacy Policy at any time. When a material change is made, we will notify registered users via the email address associated with their account at least 7 days before the change takes effect.

Your continued use of the Platform following the effective date of any updated Privacy Policy constitutes your acceptance of the revised terms. If you do not accept a material change to this Policy, you must cease using the Platform and contact our support team to arrange account closure.
