Bk4's Privacy Policy — Your information is completely secure

Bk4 (bk4.fun) is deeply committed to the privacy of its users. This Privacy Policy explains what information we collect, how it is used, and the steps we take to keep your data safe. This policy applies to all bk4 services, mobile apps, and websites.

By creating an account or using the bk4 platform, you are considered to have agreed to this Privacy Policy. We recommend reading this page carefully and reaching out to our support team if you have any questions.

Bk4 collects three types of information — what you provide directly, what is collected automatically, and what we receive from third parties. Details are outlined below:

We only collect information that is necessary to provide our services. Collecting excessive or unnecessary data goes against our policy.

Bk4 uses your personal information only for specific, legitimate purposes. We never use your data for anything unnecessary or unauthorized. Our primary purposes for using your data are:

• Facilitating account registration, verification, and management.
• Processing deposits, withdrawals, and other financial transactions.
• Monitoring for fraud and money laundering prevention.
• Handling customer support and resolving complaints.
• Sending promotions, bonuses, and personalized offers (with your consent).
• Meeting legal obligations and fulfilling regulatory requirements.
• Analyzing platform performance and conducting security analysis.

Bk4 stores your data on secure servers and retains it only for as long as necessary. Certain information may be kept longer to meet legal obligations.

• Data for active accounts is retained for the duration of the account.
• Financial transaction records are retained for up to 5 years after account closure.
• KYC documents may be retained for up to 7 years as required by law.
• Log files and security-related data are generally retained for up to 12 months.
• Marketing preference data is retained until consent is withdrawn.

Bk4 never sells or rents your personal information to third parties. Your data may only be shared in the following limited circumstances:

• Payment Processors: Shared with bKash, Nagad, or our banking partners to complete transactions.
• Legal Authorities: When a valid order is received from a court or regulatory authority.
• Security Partners: Limited data shared with technology partners for fraud prevention.
• Game Providers: Required session data shared with game studios for specific games.

In all of the above cases, we ensure that third parties adhere to privacy standards equal to or higher than our own. We are legally accountable if any data is shared beyond the scope of those agreements.

The bk4 website uses cookies and similar tracking technologies to enhance your browsing experience. Cookies are small text files stored on your device.

• Essential Cookies: Required for login sessions and security — cannot be disabled.
• Performance Cookies: Used to monitor page load speed and detect errors.
• Functionality Cookies: To remember your preferences (language, theme).
• Analytics Cookies: Analyzing user behavior to improve our services.

You can manage cookies through your browser settings. However, disabling essential cookies may cause some platform features to stop working.

As a bk4 account holder, you have important rights over your personal data. These rights are recognized under international privacy laws, and bk4 fully upholds them:

Bk4 employs industry-leading security technologies to protect your data. Our security framework is built in multiple layers, so if one layer is ever compromised, your information remains protected.

• All data is stored and transferred using 256-bit AES encryption.
• A secure connection between the website and servers is maintained using TLS 1.3 protocol.
• Passwords are never stored in plain text — only in hashed and salted form.
• An automated 24/7 monitoring system is in place to detect suspicious activity.
• Regular security audits and penetration testing are conducted.
• Data backups are stored in separate, secure locations.

That said, no internet system is 100% secure. We strongly recommend using a strong password, keeping 2FA enabled, and avoiding logging in from other people's devices.

Bk4 strictly prohibits providing services to anyone under the age of 18. Our platform is designed exclusively for adults, and we never knowingly collect or store data from minors.

Age verification is carried out at the time of registration. If an account is opened using false information and this is later discovered, the account will be suspended immediately. If a parent or guardian believes their child has registered illegally, please contact our support team.

Bk4 reserves the right to update this Privacy Policy at any time. You will be notified of significant changes via your registered email or SMS.

Continued use of the platform after any changes will be considered acceptance of the updated policy. The latest version will always be available on this page — the date of the most recent update is shown at the top of the page.

If you have any questions, complaints, or requests regarding this Privacy Policy, please get in touch with our support team. We are available 7 days a week, 24 hours a day to assist you.
