ck4 Privacy Policy

This privacy policy ("Policy") applies to the ck4 platform and all related services. When you use the ck4 website, create an account, or use any of our services, you are considered to have accepted the terms of this Policy.

ck4 considers the protection of users' personal information a fundamental responsibility. This Policy is written so you can easily understand what information is collected, why it is collected, and how it is used. This Policy should be read alongside our Terms and Conditions, as both documents together form the complete basis of the relationship between ck4 and its users.

This Policy applies only to ck4's own services. Third-party websites or services may have their own privacy policies, for which ck4 is not responsible.

ck4 collects only the information necessary to provide its services. The different types of information are described below:

2.1 Information Provided at Registration

When you create an account on ck4, the following information is collected:

• Full name
• Date of birth (for age verification — the minimum age to use the service is 21)
• Email address
• Mobile number
• Your preferred username
• Password (stored in encrypted form and never readable in plain text)

2.2 Identity Verification Information

During account verification or the withdrawal process, ck4 may request a copy of your identity document or related papers. These documents are kept under strict security and are used only for the verification process.

2.3 Transaction Information

Records of transactions completed through bKash, Nagad, Rocket, or Upay during deposits or withdrawals are stored. This includes the transaction amount, time, and mobile wallet ID.

2.4 Automatically Collected Information

Information automatically collected during site use may include:

• IP address
• Browser type and version

• Page visit history and duration
• Cookie and session data

ck4 uses your information only for specific, lawful, and service-related purposes. No information is used beyond its stated purpose.

3.1 Account Management

Your registration information is used to create and maintain your account, keep the login process secure, and send OTP verification when needed.

3.2 Transaction Processing

Transaction information is used to correctly process deposit and withdrawal requests. Withdrawals are typically completed within 15 minutes to 2 hours.

3.3 Customer Support

If you contact us for assistance via 24/7 live chat or email, your account information is used to provide fast and accurate support.

3.4 Security and Fraud Prevention

Suspicious activity is monitored to protect accounts and financial transactions. Your information is kept secure through SSL encryption and security measures.

3.5 Responsible Gaming

ck4 maintains its responsible gaming policy by monitoring user gaming behaviour. Support is provided to users when needed in accordance with our Responsible Gaming Guidelines.

3.6 Service Improvement

Analytical data is used to improve the overall experience for users and to introduce new features. This analysis is not linked to any individual's identity.

ck4 does not sell any user's personal information to third parties. However, information may be shared with the following parties in limited circumstances:

4.1 Payment Processors

The minimum information required to complete transactions through bKash, Nagad, Rocket, and Upay is shared with the relevant mobile wallet service provider. This information is used solely to verify transactions.

4.2 Technology Service Partners

Technology partners used to operate the platform may have limited access to information. They are required to comply with ck4's privacy standards and may not use the information for any other purpose.

4.3 Legal Obligations

Information may be disclosed to the relevant authorities if required under applicable Bangladeshi law or by court order. In such cases, ck4 provides only the minimum information legally required.

Cookies are used on the ck4 website. Cookies are small text files stored in your browser that improve your experience on the site.

5.1 Essential Cookies

These cookies are necessary for the site's core functions — such as maintaining login sessions and security verification. Without them, the site will not function properly.

5.2 Performance Cookies

These cookies are used to monitor how many users visit which pages and for how long, in order to improve the site's speed and performance.

5.3 Cookie Control

Cookies can be limited or disabled from your browser settings. However, disabling essential cookies may cause some parts of the site to stop working properly.

ck4 follows industry-standard technical and organisational practices to protect your information.

6.1 Encryption

SSL (Secure Socket Layer) technology is used for all data transmission. This means that information exchanged between your browser and the ck4 server cannot be read by third parties. Passwords are never stored in plain text — only in encrypted form.

6.2 Access Control

Within ck4, only authorised staff can access user information, and only within the scope of their responsibilities. A log is kept of every access.

6.3 Data Retention Period

Relevant information is retained while the account is active. After an account is closed, certain information may be kept for as long as necessary to meet legal obligations, after which it is deleted.

6.4 Incident Response Plan

If a security incident occurs, ck4 acts promptly and notifies affected users in a timely manner. This process is managed according to a pre-defined incident response plan.

ck4 believes every user has the right to reasonable control over their own information. Your key rights are described below:

7.1 Right to Access Information

You may request at any time to know what information ck4 holds about you. To do so, contact the customer support team via 24/7 live chat or email.

7.2 Right to Correct Information

If your account contains incorrect or outdated information, you may request that it be corrected. A verification process may need to be followed in some cases.

7.3 Right to Close Your Account

You may permanently close your ck4 account at any time. When an account is closed, personal information is deleted; however, certain transaction records may be retained for a set period due to legal obligations.

7.4 Right to Opt Out of Marketing Communications

If you do not wish to receive promotional messages from ck4, notify the customer support team and the necessary steps will be taken. However, important account-related messages (such as security alerts) will continue to be sent.

All ck4 services are intended solely for individuals aged 21 or older. ck4 does not knowingly collect information from anyone under the age of 21.

If a person opens an account without meeting the age requirement and this comes to ck4's attention, that account will be closed immediately and the collected information will be deleted.

If a parent or guardian believes their child has registered on ck4, please contact the customer support team without delay.

ck4 reserves the right to update this privacy policy from time to time. If significant changes are made to the policy, users will be notified by email or through the site.

If you continue using the site after a revised policy is published, you will be considered to have accepted the revised policy. It is therefore advisable to visit this page periodically. The "Last Updated" date at the top of the policy will always show the date of the current version.

To learn more about this policy, you may read our Frequently Asked Questions (FAQ) or contact customer support directly.
