ckbb Privacy Policy

This Privacy Policy ("Policy") describes how ckbb ("ckbb", "we", "us", "our") collects, uses, stores, shares, and protects personal data relating to individuals ("you", "Player", "User") who access or use the ckbb online gaming platform at ckbb.io and all associated sub-pages and services (the "Platform"). This Policy forms part of our Terms & Conditions and should be read alongside that document. By registering an account, using the ckbb Login, depositing funds, or otherwise accessing the Platform, you acknowledge that you have read and understood this Policy.

Section 1 Introduction

ckbb is committed to protecting the privacy and personal data of all players on our platform. We recognise that trust is the foundation of every player relationship, and that trust depends on transparent, fair, and lawful handling of personal information. This Policy is written in plain English so that every player — whether based in Dhaka, Chittagong, Sylhet, Khulna, or anywhere else in Bangladesh — can clearly understand their rights and our obligations.

ckbb processes personal data in accordance with internationally recognised data protection principles including purpose limitation, data minimisation, accuracy, storage limitation, integrity, confidentiality, and accountability. While Bangladesh does not yet have a comprehensive standalone data protection statute equivalent to European frameworks, ckbb voluntarily applies a high standard of data protection practice in line with global best practice for the benefit of all players.

This Policy applies to all personal data processed by ckbb in connection with the Platform, regardless of whether it is provided directly by you, collected automatically during your use of the Platform, or received from third-party partners such as payment processors and game providers.

Section 2 Data Controller

ckbb acts as the data controller in respect of personal data collected through the Platform. As data controller, ckbb determines the purposes for which personal data is processed and the means by which that processing is carried out. ckbb's contact details for all data protection enquiries are set out in Section 15 of this Policy.

Where ckbb engages third-party service providers (such as payment processors, game content providers, or identity verification services) to process personal data on its behalf, those providers act as data processors and are bound by contractual data processing agreements that restrict their use of your data to the specific purpose for which it was shared.

Section 3 Personal Data We Collect

ckbb collects the following categories of personal data in connection with the operation of the Platform:

3.1 Registration and Identity Data

• Consent: Processing for direct marketing communications (promotional emails, bonus announcements) where you have actively opted in. You may withdraw consent at any time by contacting support or updating your account communication preferences.

Section 7 Data Sharing and Third Parties

ckbb does not sell your personal data. We share personal data only in the limited circumstances described below, and only to the extent necessary for the specific purpose:

7.1 Payment Processors

To process deposits and withdrawals, ckbb shares your mobile number and transaction reference data with bKash, Nagad, Rocket, Upay, and Visa/Mastercard card processing networks as required to execute and confirm your transaction. These processors are independently operated entities with their own privacy policies governing their handling of your data.

7.2 Game Content Providers

Game providers including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi receive a player session token and stake/outcome data necessary to operate games on our platform. Game providers do not receive your full identity data, contact details, or payment method information.

7.3 Identity Verification Services

Where a third-party KYC service provider is used to verify your identity, we share your submitted identity documents and personal details with that provider. The provider processes this data solely for verification purposes and is contractually prohibited from using it for any other purpose.

7.4 Legal and Regulatory Disclosure

ckbb may disclose personal data to law enforcement agencies, regulatory bodies, or courts of competent jurisdiction where required to do so by law, court order, or in connection with the investigation of suspected fraud, money laundering, or other criminal activity.

7.5 Business Transfers

In the event of a merger, acquisition, or sale of substantially all of ckbb's business assets, player data may be transferred to the acquiring entity as part of that transaction. Players will be notified via the email address associated with their account before any such transfer takes effect, and the acquiring entity will be bound by the terms of this Policy.

Section 8 Cookies and Similar Technologies

ckbb uses cookies and similar client-side storage technologies to operate and improve the Platform. A cookie is a small text file stored on your device by your web browser when you visit our Platform. ckbb uses the following categories of cookies:

Cookie Category	Purpose	Can Be Disabled?
Strictly Necessary	Maintain your login session after you complete the ckbb Login process; remember your language and currency preferences; prevent cross-site request forgery.	No — the Platform cannot function without these.
Performance	Measure page load times, identify slow-loading resources, and monitor Platform stability and uptime.	Yes — disabling these does not affect your ability to play.
Analytics	Understand aggregate user behaviour (most-visited pages, most-played games, session length averages) to improve Platform design and content. Data is anonymised before analysis.	Yes — disabling these does not affect your ability to play.
Functional	Remember your responsible gaming settings (deposit limit values, session time-out preferences) between visits so you do not need to re-enter them each time.	Yes — but responsible gaming settings may revert to defaults.

ckbb does not use third-party advertising cookies or cross-site tracking technologies. You can manage cookie preferences through your browser settings. Note that disabling strictly necessary cookies will prevent the Platform from functioning correctly.

Section 9 Data Retention

ckbb retains personal data for the periods set out below, after which data is securely deleted or anonymised:

• Active account data: Retained for the duration of your account relationship with ckbb plus five years following account closure, in compliance with anti-money laundering record-keeping obligations.
• KYC and identity verification documents: Retained for five years from the date of verification or account closure, whichever is later.
• Financial transaction records: Retained for seven years from the date of each transaction in accordance with standard financial record-keeping requirements.
• Live chat and email support transcripts: Retained for two years from the date of the conversation, unless the conversation relates to an ongoing dispute or investigation, in which case it is retained until the matter is resolved.
• Marketing consent records: Retained for the duration of your consent and for two years following withdrawal of consent, as evidence of lawful processing.
• Server log and technical data: Retained for 90 days on a rolling basis, unless retained for longer in connection with a fraud or security investigation.

Section 10 Security Measures

ckbb implements a comprehensive set of technical and organisational security measures to protect your personal data against unauthorised access, loss, alteration, disclosure, or destruction:

• Encryption in transit: All data exchanged between your browser or app and ckbb's servers is encrypted using TLS 1.2 or higher with 256-bit AES encryption.
• Encryption at rest: Sensitive personal data stored in our databases is encrypted at rest. This includes KYC document files, financial records, and identity data.
• Password security: Passwords are hashed using bcrypt with a suitable cost factor. Plain-text passwords are never stored. ckbb staff cannot view your password — only a hash value is accessible to our systems.
• Access controls: Access to systems containing personal data is restricted to authorised ckbb personnel on a need-to-know basis. Multi-factor authentication is required for all internal system access.
• Network security: Our Platform infrastructure is protected by enterprise-grade firewalls, intrusion detection systems, and DDoS mitigation services.
• Regular security audits: ckbb conducts periodic vulnerability assessments and penetration testing of the Platform to identify and remediate security risks proactively.
• Incident response: In the event of a confirmed data breach that poses a risk to your rights, ckbb will notify affected players without undue delay via the email address associated with their account.

Despite these robust measures, no method of electronic transmission over the internet is entirely secure. ckbb cannot guarantee the absolute security of data in transit or at rest. Players are encouraged to use strong, unique passwords for their ckbb accounts and to enable SMS two-factor authentication (2FA) for an additional layer of protection.

Section 11 Your Data Rights

Subject to applicable law and certain limited exceptions, you have the following rights in respect of your personal data held by ckbb:

• Right of Access: You may request a copy of the personal data ckbb holds about you. We will provide this within 30 days of a verified request.
• Right to Rectification: You may request correction of inaccurate or incomplete personal data. Account profile updates (such as mobile number changes) can be made by contacting our support team.
• Right to Erasure: You may request deletion of your personal data where it is no longer necessary for the purpose for which it was collected, where you have withdrawn consent, or where processing is unlawful. Note that ckbb may be required by law to retain certain data (e.g., financial transaction records) even following an erasure request.
• Right to Restriction: You may request that ckbb restricts processing of your data in certain circumstances — for example, while the accuracy of data you have disputed is being verified.
• Right to Data Portability: Where processing is based on your consent or on contract performance, you may request that ckbb provides your personal data in a structured, commonly used, machine-readable format.
• Right to Object: You may object to processing based on ckbb's legitimate interests, including profiling for responsible gaming monitoring. ckbb will cease processing unless it can demonstrate compelling legitimate grounds that override your interests.
• Right to Withdraw Consent: Where processing is based on your consent (e.g., marketing communications), you may withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out prior to withdrawal.

To exercise any of the above rights, contact our support team via live chat or email at [email protected] (plain text — not a clickable link). We may require you to verify your identity before processing a data rights request. Requests will be responded to within 30 days; where a request is complex or numerous, we may extend this period by a further 30 days with notice.

Section 12 Minors and Age Restriction

The ckbb Platform is strictly for adults aged 21 years and above. ckbb does not knowingly collect personal data from persons under 21 years of age. Age verification is carried out as part of the ckbb Login registration process and via KYC documentation checks.

If ckbb becomes aware that personal data has been collected from a person under the age of 21, that account will be immediately suspended, all funds in the account will be held pending investigation, and the personal data associated with the underage account will be deleted from our systems as soon as practicable following confirmation of the player's age.

Account holders are responsible for ensuring that their ckbb Login credentials are not accessible to minors in their household. If you believe a minor has accessed the Platform using your account, please contact our support team immediately via live chat.

Section 13 International Data Transfers

ckbb's Platform infrastructure and data storage systems are hosted on servers operated by internationally reputable cloud infrastructure providers. As a result, your personal data may be stored on servers located outside Bangladesh. Where personal data is transferred internationally, ckbb ensures that appropriate safeguards are in place to protect your data to a standard equivalent to that applied within Bangladesh, including:

• Contractual data processing agreements incorporating internationally recognised standard data protection clauses.
• Transfer only to jurisdictions or entities that maintain data protection standards acceptable to ckbb's compliance function.
• Encryption of data in transit and at rest as described in Section 10.

By using the Platform, you acknowledge and consent to the transfer of your personal data to servers that may be located outside Bangladesh, subject to the safeguards described above.

Section 14 Changes to This Policy

ckbb reserves the right to update this Privacy Policy at any time to reflect changes in our data processing practices, applicable law, or Platform functionality. When material changes are made, ckbb will:

• Post the updated Policy on this page at ckbb.io/privacy-policy with a revised "Last Updated" date.
• Send a notification to the email address associated with your account at least 14 days before the changes take effect, where the changes are material to your rights.
• Display a prominent notice on the Platform for a period of not less than 14 days following publication of the updated Policy.

Your continued use of the Platform after the effective date of any update constitutes your acceptance of the revised Policy. If you do not accept the revised Policy, you must cease using the Platform and close your account prior to the effective date of the changes.
