Your Privacy at a Glance

2. Personal Data We Collect

When you register and use your mk666 account, we collect the following categories of personal data. We collect only what is necessary to deliver and improve the services you have requested and to comply with our legal and regulatory obligations.

• Identity data: your legal name, date of birth, and registered mobile number provided at registration.
• Contact data: your mobile number and, if provided, your email address, used for account notifications and support communications.
• Financial data: deposit and withdrawal history, payment method identifiers (mobile wallet numbers or bank account numbers), and transaction reference numbers.
• Gameplay data: game session logs, bet history, game outcomes, bonus usage, and responsible gaming tool settings.
• Technical data: IP address, device type, operating system, browser type and version, and session timestamps.
• Support data: the content of any communications you send to mk666 support, including chat transcripts, emails, and dispute records.

3. How We Use Your Personal Data

mk666 uses the personal data we collect for the purposes described below. We do not use your data for any purpose that is incompatible with the purpose for which it was originally collected, unless you provide your explicit consent or we are required to do so by law.

4. Legal Basis for Processing

mk666 processes your personal data on the following legal bases: (a) Contract performance — processing your registration data, payment data, and gameplay data is necessary to perform the contract between you and mk666 (i.e., to provide you with the online casino and sports betting services you have signed up for). (b) Legal obligation — we are required to collect and retain certain data (including identity verification records and transaction logs) to comply with anti-money laundering regulations and other applicable legal requirements. (c) Legitimate interests — we process technical data and usage analytics to maintain the security, stability, and integrity of the mk666 platform, provided that our legitimate interests in doing so are not overridden by your privacy rights. (d) Consent — where we send you promotional communications or process your data for any purpose not covered by the above bases, we will first obtain your explicit consent, which you may withdraw at any time by contacting support via the email in the footer of this site.

5. Payment Data and Financial Information

6. Sharing Your Personal Data

mk666 does not sell, rent, or trade your personal data to any third party for their own marketing purposes. We share your personal data only in the limited circumstances described below, and only to the extent necessary for the stated purpose.

7. Cookies and Tracking Technologies

mk666 uses cookies and similar tracking technologies to operate the platform, remember your session and preferences, detect fraud, and understand how players interact with the platform so we can improve it. A cookie is a small text file placed on your device when you visit a website. The mk666 platform uses the following types of cookies: strictly necessary cookies (required for the platform to function — these cannot be disabled), functional cookies (remember your language preference and other settings), and analytics cookies (help us understand platform usage patterns using anonymised data only).

You can control cookie usage through your browser settings. Please note that disabling strictly necessary cookies may prevent parts of the mk666 platform from functioning correctly. mk666 does not use advertising or retargeting cookies from third-party advertising networks. Any analytics data collected via cookies is anonymised and aggregated before being used for platform improvement purposes, and is never associated with your personal mk666 account record.

8. Data Retention

mk666 retains your personal data for as long as your account is active and for such period thereafter as is necessary for the purposes described in this Policy, including compliance with legal and regulatory obligations. Registration data and account records are retained for a minimum of five years following permanent account closure. Transaction records (deposit and withdrawal logs) are retained for a minimum of five years following the date of each transaction. Gameplay logs are retained for up to two years following the date of each game session, or longer if required for an ongoing dispute or investigation. Technical data (IP logs, session logs) are retained for up to twelve months. When data is no longer required, it is securely deleted or anonymised so that it can no longer be associated with any individual player.

9. Data Security

mk666 implements appropriate technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, or alteration. These measures include 256-bit SSL/TLS encryption on all data transmitted between your device and the mk666 servers, encrypted storage of sensitive account data, access controls that restrict internal access to personal data on a need-to-know basis, regular security audits and vulnerability assessments, and incident response procedures to detect, respond to, and recover from data security incidents promptly.

While mk666 takes data security seriously and implements industry-standard protections, no system is completely immune to security risks. In the event of a data breach that is likely to result in a high risk to your rights and freedoms, mk666 will notify affected players without undue delay using the contact information associated with their accounts, and will take all reasonable steps to contain the breach and minimise its impact. You can help protect your account by choosing a strong, unique password, enabling two-factor authentication, and never sharing your login credentials with any other person.

10. Your Rights Over Your Personal Data

As a player on the mk666 platform, you have the following rights in respect of your personal data. To exercise any of these rights, please contact mk666 support via the email address displayed in the footer of this page. We will respond to all rights requests within 30 days of receipt.

• Right of access: you may request a copy of all personal data mk666 holds about you.
• 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 purposes for which it was collected, subject to legal retention obligations.
• Right to restrict processing: you may request that mk666 restricts the processing of your data in certain circumstances, for example while a dispute is being investigated.
• Right to withdraw consent: where mk666 processes your data on the basis of your consent (for example, for promotional communications), you may withdraw that consent at any time without affecting the lawfulness of processing carried out before the withdrawal.

Please note that some of these rights are subject to conditions and exceptions. In particular, mk666 may decline a deletion or restriction request where retaining your data is required for compliance with legal obligations (for example, transaction records that must be retained for anti-money laundering purposes). Where mk666 declines a rights request, we will explain the reason for the refusal in writing.

11. Children and Minors

The mk666 platform is strictly for adults aged 21 and above. mk666 does not knowingly collect, store, or process personal data from any person under the age of 21. If we become aware that personal data has been submitted to mk666 by or on behalf of a person under the age of 21, we will delete that data immediately and permanently close the associated account. If you are a parent or guardian and you believe that a person under your care has registered an account on mk666, please contact us immediately via the support email displayed in the footer of this page. We will investigate and take appropriate action within 24 hours of receiving your notification.

12. Third-Party Links

The mk666 platform may contain references to the game providers and payment partners whose services are integrated into the platform (such as Evolution Gaming, Pragmatic Play, bKash, and Nagad). mk666 is not responsible for the privacy practices of any third-party service provider. Each provider operates under its own privacy policy, which governs how that provider collects and uses data in connection with its own services. mk666 strongly recommends that you review the privacy policies of any third-party service providers whose services you use in connection with your mk666 account.

13. Changes to This Privacy Policy

mk666 may update this Privacy Policy from time to time to reflect changes in our data practices, applicable law, or the services we offer. When we make material changes to this Policy, we will update the "Last updated" date at the top of this page. Where changes significantly affect your privacy rights, we will provide notice via the mk666 platform or via the contact information associated with your account before the changes take effect. Your continued use of the mk666 platform after the effective date of any updated Privacy Policy constitutes your acceptance of the revised Policy. If you do not accept the revised Policy, you must stop using the platform and may request account closure as described in our Terms & Conditions.
