tk4666 Privacy Policy – How We Handle Your Personal Data

📋 Registration and Account Data

When you create an account on tk4666, we collect the personal information you provide directly, which may include your full name, date of birth, residential address, email address, mobile phone number, and a username of your choice. This data is used to create and manage your account, verify your identity, and communicate with you about your account activity.

We may also request copies of government-issued identity documents, such as your National Identity Card (NID) or passport, to verify your age and identity in accordance with our responsible gaming obligations. Providing this information is a condition of continued account access where verification is required.

💳 Payment and Transaction Data

To process deposits and withdrawals, tk4666 collects transaction data associated with your chosen payment method. For mobile wallet payments via bKash, Nagad, Rocket, and Upay, this includes the mobile number linked to your wallet and transaction reference numbers. For bank transfers via institutions such as Dutch-Bangla Bank, BRAC Bank, City Bank, Islami Bank, or Sonali Bank, we collect the account reference details necessary to complete the transfer. For Visa and Mastercard transactions, we collect only the data passed to us by the payment processor — we do not store full card numbers on our systems.

All payment data is processed through secure, encrypted channels. Transaction histories are retained for audit, fraud prevention, and financial compliance purposes.

🖥️ Technical and Usage Data

When you use the tk4666 platform, we automatically collect certain technical information about your device and session. This includes your IP address, device type, operating system, browser type and version, referring URL, pages visited, time and duration of sessions, and game activity logs. This data is used to maintain platform security, improve service quality, detect fraud or unusual activity, and analyse how players use the platform so we can enhance the experience.

💬 Communications Data

If you contact the tk4666 support team by email or any other communication channel, we retain a record of that correspondence, including the content of your message and any attachments, for the purpose of resolving your query and maintaining a service history. Support communications are stored securely and are accessible only to authorised support staff.

📣 Marketing Communications

Where you have opted in to receive promotional emails or notifications from tk4666, we may contact you with information about new games, bonuses, seasonal promotions (such as Eid specials, BPL tournament offers, or IPL promotions), and platform updates. You may withdraw your consent and opt out of marketing communications at any time by contacting [email protected]. Withdrawing consent does not affect the lawfulness of any processing carried out before your opt-out.

🤝 When We Share Your Data

tk4666 does not sell, rent, or trade your personal data to third parties for their own commercial purposes. We may, however, share your data with carefully selected third parties under the following circumstances:

🌐 International Data Transfers

Some of our third-party service providers operate from outside Bangladesh. Where personal data is transferred internationally, we take reasonable steps to ensure that such transfers are subject to appropriate contractual protections and that the receiving party maintains data security standards consistent with this Policy. By using the tk4666 platform, you consent to these transfers where they are necessary to deliver the services you have requested.

🗂️ How Long We Keep Your Data

tk4666 retains personal data for as long as your account remains active and for a reasonable period thereafter to comply with legal obligations, resolve disputes, enforce our agreements, and maintain accurate financial records. In general:

• Account data (name, address, contact details) is retained for the duration of your account and for a period of up to 5 years following account closure.
• Transaction records are retained for a minimum of 5 years to comply with financial record-keeping obligations.
• Identity verification documents are retained in accordance with applicable verification requirements and deleted securely once the retention period expires.

Where data is no longer required for any lawful purpose, tk4666 will securely delete or anonymise it in accordance with our internal data disposal procedures.

🔒 Technical and Organisational Measures

tk4666 implements a range of technical and organisational security measures to protect your personal data against unauthorised access, disclosure, alteration, or destruction. These measures include:

• 256-bit SSL/TLS encryption for all data transmitted between your device and our servers.

Despite these measures, no data transmission over the internet can be guaranteed to be completely secure.

🔞 No Services to Under-21s

The tk4666 platform is strictly 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 player who has provided personal data is under the age of 21, we will take immediate steps to close the account, void any transactions, and securely delete the data associated with that account. If you believe that a minor has registered on the platform, please contact us immediately at [email protected].
