ck5 Privacy Policy

1. Introduction and Scope

This Privacy Policy ("Policy") sets out the practices of ck5 ("the Platform", "we", "us", "our") regarding the collection, use, storage, disclosure, and protection of personal information provided by individuals ("User", "Player", "you") who access or use our services at https://ck5.onl.

This Policy applies to all personal data collected through the ck5 website, mobile browser experience, customer support channels, and any other service operated under the ck5 brand. It covers data collected directly from you as well as data gathered automatically when you interact with our Platform.

By registering an account on ck5 or continuing to use our services, you acknowledge that you have read and understood this Policy and consent to the collection and use of your personal information as described herein. If you do not agree with any part of this Policy, you should discontinue use of the Platform and contact [email protected] to request account closure.

This Policy should be read alongside our Terms & Conditions and Responsible Gaming Policy, both of which are available on this website and form part of the overall agreement between you and ck5. In the event of any conflict between this Policy and a more specific data notice provided to you at the point of collection, the specific notice will prevail.

3. How We Use Your Personal Data

ck5 processes your personal data only where we have a lawful basis for doing so. The primary purposes for which we use your data, and the corresponding lawful basis for each, are set out below:

4. Sharing Your Personal Data

ck5 does not sell or rent your personal data to any third party. We may share your data only in the following limited and controlled circumstances:

4.1 Payment Service Providers

We share the minimum necessary financial data with our payment processing partners — including bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, Islami Bank, Sonali Bank, Visa, and Mastercard — solely to process your deposits and withdrawals. These partners are contractually bound to handle your data in accordance with applicable data protection standards and may not use it for their own marketing purposes.

4.2 Game Software Providers

When you play games provided by third-party studios — including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi — limited session data (such as player ID and bet amounts) is transmitted to those providers to facilitate gameplay, maintain game integrity, and resolve disputes. These providers are bound by data processing agreements that restrict their use of your data.

4.3 Legal and Regulatory Authorities

We may disclose your personal data to law enforcement agencies, regulatory bodies, or courts of competent jurisdiction when we are legally compelled to do so, when disclosure is necessary to protect the rights, property, or safety of ck5, our players, or the public, or when we are required to cooperate with an official investigation.

4.4 Business Transfers

In the event of a merger, acquisition, reorganisation, or sale of all or substantially all of the assets of ck5, your personal data may be transferred to the successor entity as part of that transaction. We will notify registered players by email prior to any such transfer and will ensure that the receiving entity is bound by privacy obligations no less protective than those set out in this Policy.

5. Data Retention

ck5 retains your personal data for as long as your account is active and for a defined period after account closure, in accordance with our legal obligations and legitimate business needs. The general retention schedule is as follows:

• Account and Identity Data: Retained for a minimum of 5 years following account closure to comply with anti-money laundering record-keeping requirements.
• Transaction and Financial Data: Retained for a minimum of 5 years from the date of each transaction.
• Customer Support Records: Retained for up to 5 years from the date of the relevant interaction.
• Responsible Gaming Records: Self-exclusion records are retained indefinitely to prevent re-registration by excluded players.
• Technical and Usage Data: Retained in anonymised, aggregated form for up to 2 years after collection.
• Cookie Data: Session cookies are deleted when your browser session ends. Persistent preference cookies expire within 12 months.

Upon expiry of the applicable retention period, personal data is securely deleted or anonymised in accordance with industry-standard data destruction practices.

6. Your Data Rights

You have the following rights in relation to the personal data that ck5 holds about you. To exercise any of these rights, please contact our support team in writing at [email protected]. We will acknowledge your request within 5 business days and fulfil it within 30 days, subject to identity verification.

7. Cookies and Similar Technologies

ck5 uses cookies — small text files stored on your device — and similar local storage technologies to enable the Platform to function correctly, remember your preferences, and gather anonymised analytics data. We do not use third-party advertising cookies or cross-site tracking pixels.

Types of Cookies We Use

• Strictly Necessary Cookies: Required for the Platform to operate. These include session authentication cookies that keep you logged in during your visit. They cannot be disabled without preventing core functionality.
• Preference Cookies: Store your language and display preferences so you do not need to re-enter them on each visit. These expire within 12 months.
• Analytics Cookies: Collect anonymised, aggregate data about how visitors navigate and use the Platform. This data is used exclusively to improve our services and is never linked back to an individual player's identity.

You may configure your browser to block or delete cookies at any time. Note that blocking strictly necessary cookies will prevent you from logging in to your ck5 account. For full instructions on managing cookies, please refer to your browser's help documentation.

8. Data Security

ck5 employs a comprehensive set of technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, or disclosure. Our security framework includes:

• 256-bit SSL/TLS encryption for all data transmitted between your device and our servers.
• Encrypted storage of sensitive data at rest, including payment credentials and identity documents.
• Role-based access controls that restrict internal access to personal data to authorised personnel only, on a need-to-know basis.
• Regular penetration testing and vulnerability assessments conducted by independent security specialists.
• Multi-factor authentication requirements for internal administrative access to production systems.
• Incident response procedures that require notification to affected players within 72 hours of discovering a personal data breach that poses a risk to their rights and freedoms.

While ck5 takes all reasonable precautions to secure your data, no online platform can guarantee absolute security against all possible threats. You are responsible for keeping your login credentials confidential and for notifying us immediately at [email protected] if you suspect any unauthorised access to your account.

9. Children and Under-Age Users

The ck5 Platform is strictly intended for adults aged 21 years and above. We do not knowingly collect personal data from individuals under the age of 21. If we become aware that a registered account belongs to a person under 21, we will immediately close that account, delete all associated personal data to the extent permitted by our legal retention obligations, and report the matter to our compliance team.

If you have reason to believe that a minor has created an account on ck5, please notify us immediately at [email protected] so that we can take prompt action.

10. Changes to This Privacy Policy

ck5 reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data practices, applicable law, or the services we offer. The effective date at the top of this page will be updated to reflect the date of the most recent revision.

Where changes are material — meaning they significantly affect how we collect, use, or share your data — we will notify registered players by email at least 7 days before the revised Policy takes effect. For non-material changes, we may update the Policy without advance notice. Your continued use of the Platform following publication of any revised Policy constitutes your acceptance of the updated terms.

We encourage you to review this Policy periodically. The current version is always available at https://ck5.onl/privacy-policy.
