ck644 Privacy Policy – How We Handle Your Data

Introduction and Scope

This Privacy Policy ("Policy") is issued by ck644 ("the Platform", "we", "us", "our") and applies to all personal data collected from individuals ("User", "Player", "you", "your") who access, register with, or use any service offered through the ck644 website and mobile web platform. By creating an account and using ck644, you acknowledge that you have read and understood this Policy and consent to the collection, processing, and storage of your personal data as described herein.

ck644 is committed to handling all personal data responsibly, transparently, and in compliance with applicable data protection principles. This Policy should be read in conjunction with ck644's Terms and Conditions, which govern your overall use of the platform. In the event of any conflict between this Policy and the Terms and Conditions regarding the treatment of personal data, the terms of this Policy shall prevail.

What Data We Collect

ck644 collects personal data only to the extent necessary to provide safe, compliant, and high-quality gaming services to players in Bangladesh. The categories of personal data we collect are set out below.

ck644 does not collect sensitive personal data such as racial or ethnic origin, political opinions, religious beliefs, genetic data, or biometric data for the purpose of uniquely identifying a person. Where age verification requires review of identity documents, those documents are processed only for the purpose of confirming eligibility and are not used for any other purpose.

How We Use Your Data

ck644 uses personal data solely for the following defined purposes. We do not use your data for purposes that are incompatible with those listed below, and we do not use automated decision-making to take decisions with significant legal or similarly significant effect on individuals without human review.

• Account creation, management, and authentication: to create and maintain your ck644 account, verify your identity at login, and keep your account credentials secure.
• KYC and compliance: to verify your age, identity, and eligibility to use the platform in compliance with our responsible gaming obligations and anti-money laundering requirements.
• Payment processing: to facilitate deposits and withdrawals via bKash, Nagad, Rocket, Upay, and other supported payment methods, and to maintain accurate financial records of all transactions.
• Responsible gaming monitoring: to track gaming activity for signs of problematic gambling behaviour, to apply and enforce the responsible gaming tools you have set on your account, and to intervene proactively where necessary to protect player welfare.
• Fraud and security: to detect, investigate, and prevent fraudulent transactions, account abuse, money laundering, collusion, and other prohibited conduct as defined in our Terms and Conditions.
• Service improvement and personalisation: to analyse platform usage patterns, improve our games and features, and where you have given consent, to send you relevant promotional communications about offers and bonuses on ck644.

ck644 will not use your personal data for any purpose that was not disclosed at the time of collection without first obtaining your explicit consent or establishing another valid legal basis for the new purpose. If we intend to use your data for a materially different purpose in the future, we will notify you in advance and, where required, seek your consent before doing so.

Legal Basis for Processing

ck644 processes personal data only where there is a valid legal basis for doing so. The legal bases on which we rely are described below in relation to the main processing activities carried out on the platform.

Contractual Necessity

Processing of identity data, contact data, financial data, and gaming activity data is necessary for the performance of the contract between you and ck644 — specifically, to provide you with a registered account, to process your deposits and withdrawals, to credit winnings to your account, and to enforce the Terms and Conditions that govern your use of the platform.

Legal Obligation

Processing for KYC verification, age verification, anti-money laundering checks, fraud investigation, and responsible gaming monitoring is carried out to comply with legal and regulatory obligations applicable to the operation of the platform. ck644 is required to retain certain records of these activities for defined periods.

Legitimate Interests

Processing of technical and usage data for platform security, fraud prevention, and service improvement is carried out on the basis of ck644's legitimate interest in operating a secure, reliable, and fair gaming environment. ck644 has assessed that this processing does not override the privacy interests of individual users given the limited nature of the data processed and the security controls in place.

Consent

Processing for direct marketing communications (promotional emails, bonus notifications, and personalised offers) is carried out only where you have given your explicit consent. You may withdraw your consent to marketing communications at any time by contacting ck644 support or by updating your communication preferences in your account settings. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

Sharing Your Data

ck644 does not sell, rent, or trade your personal data to any third party. We share personal data with third parties only in the following limited circumstances:

• Game providers (e.g. Pragmatic Play, Evolution Gaming, Spribe, Ezugi): ck644 shares minimum necessary session and account data with licensed game providers to enable game delivery, result verification, and RTP auditing. Game providers are contractually bound to process this data only for these purposes.
• Payment processors (bKash, Nagad, Rocket, Upay, BRAC Bank, City Bank): ck644 shares the minimum necessary transaction data with payment processors to facilitate deposits and withdrawals. These providers operate under their own regulatory frameworks and privacy policies.
• Fraud prevention and KYC service providers: ck644 uses specialist third-party identity verification and fraud detection services. These providers process data under strict data processing agreements and may not use the data for any purpose beyond those services.
• Legal and regulatory authorities: ck644 will disclose personal data to law enforcement, regulatory bodies, or courts where required to do so by applicable law, court order, or regulatory direction. ck644 will notify affected users of such disclosures where legally permitted to do so.

Cookies and Tracking Technologies

ck644 uses cookies and similar tracking technologies (collectively "Cookies") to operate the platform, remember your session, and improve your user experience. This section explains the types of Cookies we use, their purpose, and how you can manage them.

Strictly Necessary Cookies

These Cookies are essential for the platform to function correctly. They enable core functionality such as session management, secure login, and navigation between pages. Strictly necessary Cookies cannot be disabled without preventing you from using the platform. No consent is required for these Cookies as they are technically necessary for service delivery.

Functional Cookies

Functional Cookies enable the platform to remember your preferences, such as your chosen language setting, responsible gaming tool configurations, and display preferences. These Cookies improve the quality of your experience but are not strictly necessary. They are activated only where you have not disabled them in your browser settings.

Analytics Cookies

Analytics Cookies help ck644 understand how players use the platform — which pages are visited most frequently, where users encounter errors, and how navigation flows are used. This data is aggregated and anonymised where possible and is used solely to improve the platform. ck644 does not use analytics data to build individual user profiles for marketing or advertising purposes. You may opt out of analytics Cookies by adjusting your browser settings or device privacy controls.

Data Security

ck644 implements appropriate technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, alteration, disclosure, or destruction. These measures include, but are not limited to: SSL/TLS encryption for all data transmitted between your device and the platform; encrypted storage of sensitive account and financial data; access controls that restrict internal access to personal data on a strict need-to-know basis; regular security assessments and penetration testing of platform infrastructure; and staff training on data protection obligations and information security best practices.

While ck644 takes data security seriously and invests continuously in its security infrastructure, no online platform can guarantee absolute security against all threats. In the event of a personal data breach that is likely to result in a high risk to your rights and freedoms, ck644 will notify affected users without undue delay, providing details of the breach, the data affected, and the steps taken to mitigate the impact. Users are also encouraged to take personal security measures, including using a strong, unique password for their ck644 account and enabling two-factor authentication where available.

Data Retention

ck644 retains personal data only for as long as is necessary for the purposes for which it was collected, subject to any applicable legal retention obligations that may require data to be kept for longer periods. The following general retention periods apply: active account data is retained for the duration of the account relationship and for a period of five years following account closure; KYC and identity verification documents are retained for a minimum of five years from the date of account closure in compliance with applicable anti-money laundering obligations; transaction records are retained for a minimum of five years from the date of the transaction; responsible gaming records (including self-exclusion records) are retained for a minimum of seven years to support the effectiveness of player protection measures over time.

Upon expiry of the applicable retention period, personal data will be securely deleted or anonymised so that it can no longer be associated with an identified or identifiable individual. Where data is anonymised rather than deleted, ck644 may continue to use that anonymised data for analytical and platform improvement purposes, as it no longer constitutes personal data.

Your Rights Over Your Personal Data

Subject to applicable law, you have the following rights in respect of the personal data that ck644 holds about you. To exercise any of these rights, please contact ck644 support using the contact details provided at the end of this Policy. ck644 will respond to all verified rights requests within a reasonable period.

These rights are not absolute and may be subject to limitations under applicable law — for example, ck644 may be required to retain certain data for anti-money laundering compliance even if you request erasure. Where ck644 is unable to fulfil a rights request in full, we will explain the reason and the extent to which the request can be fulfilled. You also have the right to raise a complaint with a relevant data protection supervisory authority if you believe your data has been processed unlawfully.

Protection of Minors

ck644 strictly prohibits use of the platform by persons under the age of 21. We do not knowingly collect personal data from persons under 21. If we become aware that personal data has been collected from a person under the minimum age, we will immediately close the associated account, delete the personal data collected, and return any deposited funds subject to verification checks. Parents and guardians who believe a minor may have accessed ck644 are encouraged to contact our support team immediately so that the account can be reviewed and closed without delay. ck644 also encourages households with minors to use appropriate parental control software on shared devices to prevent access to online gaming platforms.

Changes to This Privacy Policy

ck644 reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data processing practices, applicable law, or platform functionality. Where changes are material — meaning they significantly affect the way in which we collect, use, or share your personal data — we will notify registered users in advance via the platform or by email. The notice period for material changes will be a minimum of 14 days prior to the effective date of the revised Policy.

The date at the top of this Policy reflects when it was last updated. Your continued use of ck644 after the effective date of any revised Policy constitutes your acceptance of the revised terms. The current version of this Privacy Policy is always available on the ck644 website. If you have concerns about any proposed changes, you are welcome to contact our support team before the changes take effect.
