dhk71 Privacy Policy

1. Who We Are

1.1 dhk71 ("we", "us", "our") operates the online betting and casino platform accessible at https://dhk71.io. We are the data controller responsible for the personal data collected through the platform.

1.2 Our primary market is Bangladesh, and our platform is designed to serve adult players (aged 21 and above) located across Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, Barisal, Rangpur, Mymensingh, Cox's Bazar, and the rest of Bangladesh.

1.3 All questions, concerns, or formal requests relating to this Privacy Policy should be directed to our support team at [email protected]. We aim to respond to all privacy-related inquiries within 30 days of receipt.

2. Data We Collect

2.1 We collect personal data in several categories depending on the nature of your interaction with the dhk71 platform. The table below sets out the main categories of data we hold and typical examples within each category:

2.2 We do not collect sensitive personal data such as racial or ethnic origin, political opinions, religious beliefs, biometric data, or health data, except where strictly required by applicable law (for example, medical documentation in the context of a responsible gaming self-exclusion request).

3. How We Collect Data

3.1 Directly from you — when you register an account, complete the KYC verification process, make a deposit or withdrawal, place a bet, contact our support team, or respond to a survey or promotion.

3.2 Automatically — through your use of the platform, we collect Technical Data and Usage Data via server logs, session cookies, local storage, and standard web analytics tools. This data is collected automatically whenever you access the dhk71 website or mobile application.

3.3 From third-party service providers — our payment processors (bKash, Nagad, Rocket, Upay, Visa, Mastercard) and identity verification partners may share data with us as part of transaction processing or KYC fulfilment. We only receive data from these providers that is necessary to complete the relevant operation.

3.4 From public sources — in limited circumstances, we may cross-reference publicly available information (for example, public records) to verify the accuracy of the information you have provided to us, particularly during the KYC process.

4. How We Use Your Data

4.1 dhk71 uses the personal data we collect for the following specific purposes:

• Account creation and management — to register your account, verify your identity, maintain your profile, and process your account-related requests.
• Service delivery — to allow you to access and use all features of the platform, including sports betting, live casino, slots, Aviator, and virtual sports.
• Payment processing — to process deposits and withdrawals securely via your chosen payment method (bKash, Nagad, Rocket, Upay, Visa, or Mastercard) and to maintain accurate financial records.
• KYC and fraud prevention — to verify your age and identity, detect and prevent fraudulent activity, money laundering, and other prohibited conduct as described in our Terms & Conditions.
• Responsible gaming — to monitor betting patterns for signs of problem gambling, apply limits and restrictions you have set, and proactively reach out where our systems flag potential harm.
• Customer support — to respond to your support queries, process complaints, and maintain records of our communications for quality assurance and dispute resolution.
• Legal compliance — to fulfil our obligations under applicable laws and regulations, including record-keeping requirements and responses to lawful requests from authorities.
• Marketing and promotions — to send you information about bonuses, promotions, and new features, but only where you have given your explicit consent to receive such communications. You may withdraw consent at any time.
• Platform improvement — to analyse usage patterns and technical performance so that we can improve the platform experience, fix bugs, and develop new features.
• Security — to monitor our systems for unauthorised access, protect User accounts from being compromised, and maintain the overall integrity of the dhk71 platform.

4.2 We do not use personal data to make fully automated decisions that produce legal or similarly significant effects on Users without human review. Where automated tools flag an account for review (for example, due to suspected fraud), a member of our team reviews the case before any action is taken.

5. Legal Basis for Processing

5.1 We process your personal data on one or more of the following legal bases, depending on the purpose:

• Contractual necessity — processing required to fulfil our contract with you (i.e., providing the platform services, processing payments, managing your account).
• Legal obligation — processing required to comply with applicable laws, including anti-money-laundering regulations, KYC requirements, and record-keeping obligations.
• Legitimate interests — processing necessary to pursue our legitimate business interests, such as fraud prevention, security monitoring, and platform analytics, provided these interests are not overridden by your rights and freedoms.
• Consent — processing for purposes where we have obtained your specific, informed consent, such as sending marketing communications. You may withdraw consent at any time by contacting [email protected] or using the opt-out mechanism in any marketing message.

6. Sharing Your Data

6.1 dhk71 does not sell, rent, or trade your personal data to third parties for their own commercial purposes under any circumstances.

6.2 We may share your data with carefully selected third-party service providers who assist us in operating the platform. These providers act as data processors on our behalf and are contractually required to process your data only according to our instructions and to maintain appropriate security standards. Categories of such providers include:

• Payment processors — bKash, Nagad, Rocket, Upay, Visa, Mastercard, and their acquiring partners, for the purpose of processing deposits and withdrawals.
• Identity verification providers — specialist KYC and age-verification services used to validate government-issued identity documents.
• Game content providers — studios such as Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi, who deliver their game content directly to your browser via the dhk71 platform. These providers may collect limited technical data (such as game session IDs) as part of normal game operation.
• Cloud infrastructure and hosting providers — secure data centre and cloud service providers used to host the platform and its databases.
• Customer support software providers — platforms used to manage live chat and email support interactions.
• Analytics providers — tools used to analyse platform usage in aggregate. Where possible, analytics data is anonymised before processing.

6.3 We may disclose your personal data to law enforcement agencies, regulatory bodies, courts, or other public authorities where we are required to do so by applicable law, or where disclosure is necessary to protect the rights, property, or safety of dhk71, its users, or the public.

6.4 In the event of a merger, acquisition, or sale of all or part of the dhk71 business, your personal data may be transferred to the acquiring entity as part of that transaction, subject to the same protections described in this Privacy Policy.

7. Cookies & Tracking Technologies

7.1 dhk71 uses cookies and similar tracking technologies (including local storage and session tokens) to operate the platform, remember your preferences, maintain your login session, and analyse how the platform is used.

7.2 The main categories of cookies we use are:

• Essential cookies — required for the platform to function. These include session authentication tokens and security cookies. They cannot be disabled without breaking core platform functionality.
• Functional cookies — used to remember your preferences such as language settings, preferred payment method, and responsible gaming limit configurations.
• Analytics cookies — used to understand how users navigate the platform so that we can identify popular features, diagnose errors, and improve user experience. Data collected by analytics cookies is aggregated and does not identify individual users.
• Marketing cookies — used only with your consent to track the effectiveness of promotional campaigns and personalise bonus offers. You may opt out of marketing cookies at any time.

7.3 You can control cookies through your browser settings. Disabling essential cookies will prevent you from using core platform features including logging in and placing bets. Disabling non-essential cookies will not affect your ability to use the platform but may limit certain personalisation features.

8. Data Security

8.1 dhk71 implements industry-standard technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, or disclosure. Key measures include:

• 256-bit SSL/TLS encryption for all data transmitted between your device and our servers.
• Encrypted storage of passwords using industry-standard hashing algorithms. Plain-text passwords are never stored.
• Role-based access controls limiting internal access to personal data on a strict need-to-know basis.
• Regular security audits and penetration testing of platform infrastructure.
• Two-factor authentication (2FA) available for all user accounts and mandatory for internal staff systems.
• Automated intrusion detection systems monitoring platform traffic for suspicious activity in real time.

8.2 Despite these measures, no internet-based platform can guarantee absolute security. In the event of a data breach that is likely to result in a risk to your rights and freedoms, dhk71 will notify affected users without undue delay.

8.3 You are responsible for keeping your own account credentials confidential. If you suspect your account has been compromised, contact [email protected] immediately so that we can secure your account.

9. Data Retention

9.1 We retain personal data for as long as necessary to fulfil the purpose for which it was collected, or as required by applicable law. The table below summarises our standard retention periods by data category:

9.2 Once a retention period has expired, data is either securely deleted or fully anonymised so that it can no longer be associated with any individual user. Anonymised data may be retained indefinitely for aggregate statistical analysis.

10. Your Rights

10.1 As a user of the dhk71 platform, you hold the following rights with respect to your personal data. To exercise any of these rights, contact us at [email protected] with your account username and a description of your request. We will respond within 30 calendar days.

• Right of access — you may request a copy of all personal data we hold about you, along with information about how it is processed.
• Right to rectification — you may request correction of any inaccurate or incomplete personal data we hold about you.
• Right to erasure — you may request deletion of your personal data where it is no longer necessary for the purpose it was collected, where you withdraw consent, or where we have no legal basis for continued processing. Note that some data must be retained to comply with legal obligations (see Section 9) and cannot be deleted on request.
• Right to restrict processing — you may request that we restrict the processing of your data in certain circumstances, for example while a dispute about accuracy is resolved.
• Right to data portability — you may request a structured, machine-readable copy of the personal data you have provided to us, for the purpose of transferring it to another service provider.
• Right to object — you may object to processing carried out on the basis of legitimate interests or for direct marketing purposes. Where you object to direct marketing, we will stop immediately.
• Right to withdraw consent — where processing is based on your consent, you may withdraw that consent at any time without affecting the lawfulness of prior processing.

10.2 We will not charge a fee for exercising your rights unless a request is manifestly unfounded or excessive. In such cases, we will explain the reason and any applicable fee before proceeding.

11. Children's Privacy

11.1 The dhk71 platform is strictly intended for adults aged 21 years and above. We do not knowingly collect personal data from any person under the age of 21. Account registration requires confirmation of minimum age, and KYC verification is used to enforce this requirement.

11.2 If we become aware that personal data has been collected from a person under the age of 21, we will delete that data immediately, close the associated account, and handle any funds in the account in accordance with our underage gambling policy as set out in the Terms & Conditions.

11.3 If you believe a person under the age of 21 has registered an account on dhk71, please contact us immediately at [email protected] so that we can investigate and act without delay.

12. International Data Transfers

12.1 In order to deliver our services, some of your personal data may be transferred to and processed by service providers located outside Bangladesh. Where such transfers occur, we take steps to ensure that your data receives an equivalent level of protection as it would under applicable Bangladeshi law.

12.2 Safeguards we apply to international data transfers include: using only service providers who operate under recognised data protection frameworks; incorporating data processing agreements with appropriate contractual clauses; and limiting the scope of data transferred to the minimum necessary for the service being provided.

12.3 Game content delivered by third-party studios (Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, Ezugi, and others) may be hosted on infrastructure located outside Bangladesh. These providers are contractually bound to process any user data in accordance with applicable data protection requirements.

13. Third-Party Links

13.1 The dhk71 platform does not contain links to external third-party websites. All links within the platform navigate to other sections of https://dhk71.io. Accordingly, this section is provided for completeness and transparency only.

13.2 If you independently navigate to any third-party website (for example, the website of a payment provider such as bKash or Nagad), that website's own privacy policy governs the collection and use of your data. dhk71 is not responsible for the privacy practices of any third-party services accessed independently by Users.

14.1 dhk71 reserves the right to update or amend this Privacy Policy at any time. The "Last updated" date at the top of this document reflects the date on which the most recent revision was made.

14.2 Where changes are material — that is, where they significantly affect how we collect, use, or share your personal data — we will notify registered users by email and/or via an in-platform notification at least 14 days before the changes take effect.

14.3 Your continued use of the dhk71 platform following the effective date of any revised Privacy Policy constitutes your acceptance of the changes. If you do not agree with the revised policy, you must cease using the platform and may request account closure by contacting [email protected].
