tk5667 Privacy Policy — How we use your information

Tk5667 only collects information that is necessary to provide its services. Minimizing data collection is a core part of our policy.

• Registration Information: Full name, mobile number, email address, date of birth, and preferred username.
• KYC Verification Data: National ID (NID) number and photo — required only at the time of your first withdrawal.
• Payment Information: bKash/Nagad number, bank account details (if applicable), and transaction history.
• Activity Data: Login timestamps, device and browser used, IP address, betting history.
• Contact Information: Messages and chat history sent to support — used for issue resolution and service quality improvement.
• Cookies & Session Data: Technical information is collected automatically to improve your experience on the site.

Every piece of data we collect has a specific, legitimate reason behind it. We never collect information on the basis that it might come in handy someday.

• To create and manage your account — and to verify that you are who you say you are.
• To process payments and keep deposits and withdrawals secure.
• To verify age and identity — ensuring no one under 18 can access the service.
• To detect and prevent fraud — protecting your account and funds.
• To improve customer service and resolve issues more efficiently.
• To meet legal and regulatory obligations — where applicable.
• To inform you of relevant offers and bonuses — but only with your consent.

All data on tk5667 is stored on secure, encrypted servers. Different types of information are protected by separate layers of security.

• General account data is stored in an encrypted database — accessible only to authorized personnel.
• KYC documents (NID photos) are stored in a separate, high-security storage environment — isolated from the general database.
• Payment information is stored in compliance with PCI-DSS standards — card numbers and payment PINs are never stored.
• Server firewalls and intrusion detection systems are active 24/7.
• Regular security audits are conducted — any vulnerabilities are identified and addressed promptly.

We are fully transparent about where your data may go. In short: tk5667 does not sell your data or share it for advertising purposes.

• Payment Processors: Only the information necessary to process a transaction is shared with bKash, Nagad, or your bank.
• KYC Service Provider: Trusted third parties are used for identity verification — they are bound by their own privacy policies.
• Law Enforcement: Data may be disclosed in response to a valid legal order or court directive.
• Anti-Fraud System: Limited data may be shared with specialized systems for fraud prevention purposes.
• No data is shared with advertisers or marketing companies.
• When data is shared with third parties, it is strictly for a defined purpose and limited to the minimum necessary.

Tk5667 uses cookies on this website — they are necessary for the site to function smoothly. Cookies do not collect personal information.

• Necessary Cookies: Essential for login sessions and security — these cannot be disabled.
• Performance Cookies: This helps us identify where the site may be slow — no personal data is collected.
• Preference Cookies: Your language and display preferences are remembered, making future logins more convenient.
• Performance and preference cookies can be disabled from your browser settings, though some features may not function as expected.
• Tk5667 does not use third-party advertising tracking cookies.

We retain your data only for as long as it is needed — no longer. Even after an account is closed, certain information may need to be kept for a defined period for legal and compliance reasons.

• Data for active accounts is retained until the account is closed.
• Transaction records are retained for 5 years after account closure for legal and regulatory compliance.
• KYC documents may be retained for up to 3 years after account closure.
• Support chat history is retained for up to 1 year.
• Once the retention period ends, data is permanently deleted — it is not kept in any backup.

As a tk5667 user, you have certain fundamental rights. To exercise any of them, contact our support team directly.

• Right to Know: You have the right to know what personal information we hold about you.
• Right to Rectification: You can request corrections to any inaccurate or outdated information.
• Right to Erasure: When closing your account, you may request the deletion of any data that is not required to be retained.
• Right to Object to Processing: You may object to the use of your data for specific purposes.
• Data Portability: You can request to receive your data in a standard portable format.
• We will respond to any rights request within 30 days of receipt.

Tk5667 goes beyond written policies — real technical measures are in place to protect your data, and they work around the clock.

• HTTPS is enforced across all connections — the site will never load over HTTP.
• Passwords are never stored in plain text — we use bcrypt hashing.
• Multiple failed login attempts will temporarily lock your account — to protect against brute force attacks.
• OTP verification is mandatory when logging in from a new device.
• Regular penetration testing is conducted to identify potential security vulnerabilities.
• Staff access is limited to the minimum level required — no one can view data beyond what their role demands.

Tk5667 is strictly for users aged 18 and above. Ensuring we never collect data from minors is something we take very seriously.

• Date of birth is verified at registration — anyone under 18 is not allowed to create an account.
• Age is definitively verified during KYC using your NID.
• If we become aware that any minor's data has been collected, it is deleted immediately and the account is closed.
• Parents wishing to close their child's account should contact us at support@tk5667.best.

We update this policy when necessary. Maintaining transparency throughout any changes is a commitment we stand by.

• If this policy is updated, the "Last Updated" date at the top of this page will reflect the change.
• You will be notified of any significant changes via your registered mobile number or account notifications.
• Continued use of the service after any changes will be considered acceptance of the updated policy.
• If you object to the updated policy, please close your account and notify us at support@tk5667.best.
