Last updated: January 2026

Introduction

This Privacy Policy (the "Policy") describes how tk668 ("we", "us", "our", or "the Platform") collects, processes, stores, and protects the personal data of individuals ("you" or "the Player") who access or use the tk668 website at tk668.bio, including all associated gaming, betting, payment, and customer support services. This Policy applies to all players accessing tk668 from Bangladesh, including players located in Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, Barisal, Rangpur, Mymensingh, and Cox's Bazar.

By registering an account with tk668, making a deposit, placing a wager, or otherwise using the Platform, you acknowledge that you have read and understood this Policy and consent to the collection and processing of your personal data as described herein. If you do not consent to this Policy, please do not use the Platform. We may update this Policy from time to time; the most current version is always available at tk668.bio/privacy-policy.

Personal Data We Collect

tk668 collects personal data that is necessary to provide a safe, fair, and compliant online gaming and betting service. We collect data in the following categories.

• Registration data: your name, date of birth, mobile number, and any other information you provide when creating your tk668 account. This data is required to verify your eligibility to use the Platform, including confirming that you are 21 years of age or older.
• Identity verification documents: copies of government-issued identification (such as a National ID card or passport) that we may request to complete KYC obligations. These documents are used solely for identity verification and are stored securely.
• Transaction data: records of deposits and withdrawals processed via bKash, Nagad, Rocket, Upay, or other supported payment methods. We record transaction amounts, timestamps, and the payment method used. We do not store full payment credentials or mobile banking PINs.
• Gaming and wagering activity: records of games played, bets placed, bet amounts, game outcomes, and session durations. This data is retained for regulatory compliance, responsible gaming monitoring, and dispute resolution purposes.
• Technical and device data: your IP address, browser type and version, operating system, device model, mobile network, and session timestamps. This data is collected automatically when you access the Platform and is used for security monitoring, fraud detection, and platform optimisation.
• Customer support communications: records of any communications you initiate with our support team, including the content of messages, the subject matter of your enquiry, and the resolution provided. These records are retained to improve service quality and for audit purposes.

How We Use Your Personal Data

tk668 processes your personal data only for the purposes for which it was collected, as described below. We do not use your data for any purpose that is incompatible with the purpose for which it was originally collected without your prior consent.

• Account management: to create and maintain your tk668 account, verify your identity, manage your preferences and responsible gaming settings, process deposits and withdrawals, and communicate account-related notifications to you.
• Service delivery: to provide you with access to the games, betting markets, promotional offers, and customer support functions available on the Platform.
• Regulatory compliance and KYC: to meet our obligations under applicable anti-money-laundering rules, age verification requirements, and other regulatory obligations that apply to online gaming and payment services.
• Fraud prevention and security: to detect, investigate, and prevent fraudulent transactions, unauthorised account access, money laundering, bonus abuse, and other activities that breach our Terms and Conditions or applicable law.
• Responsible gaming: to monitor gaming patterns that may indicate problem gambling behaviour, to apply deposit limits, session restrictions, and cooling-off periods requested by the player, and to comply with self-exclusion requests.
• Platform improvement and analytics: to analyse aggregated, anonymised usage data in order to understand how players use the Platform and to make improvements to game selection, site performance, and mobile optimisation. Individual player profiles are not used for this purpose.

Legal Basis for Processing

tk668 processes your personal data on one or more of the following legal bases, depending on the specific processing activity.

• Contractual necessity: the processing of your registration data, transaction data, and gaming activity data is necessary to perform the contract between you and tk668 — that is, to provide you with the online gaming and betting services you have requested.
• Legal obligation: the processing of identity verification documents, transaction records, and certain gaming activity data is required to comply with applicable anti-money-laundering, age verification, and other regulatory requirements.
• Legitimate interests: the processing of technical and device data for fraud detection, security monitoring, and platform optimisation is carried out on the basis of tk668's legitimate interest in maintaining a secure, fair, and well-functioning platform.
• Consent: where we send you promotional communications about bonuses or seasonal offers, we do so on the basis of your consent. You may withdraw your consent to receive such communications at any time by contacting our support team or adjusting your account notification preferences.

How tk668 Protects Your Privacy

Sharing Your Personal Data

tk668 does not sell or share your personal data with third parties for their own marketing or commercial purposes. We share your data only in the limited circumstances described below, and only to the minimum extent necessary for the relevant purpose.

• Payment processors: we share transaction data with bKash, Nagad, Rocket, Upay, and other payment service providers solely to process your deposits and withdrawals. These providers process your data under their own privacy policies and are contractually required to handle your data securely.
• Game studios and technology providers: we share limited technical data with game studios (including Pragmatic Play, Evolution Gaming, Spribe, Ezugi, NetEnt, and Microgaming) and platform technology providers solely to facilitate game delivery, ensure fair play, and maintain platform performance.
• Regulatory and law enforcement authorities: we may disclose your personal data to relevant authorities where we are required to do so by applicable law, a court order, or a lawful request from a competent law enforcement agency. We will notify you of any such disclosure where we are legally permitted to do so.
• Business transfers: in the event of a merger, acquisition, or sale of all or substantially all of tk668's business assets, player data may be transferred as part of that transaction. We will notify affected players in advance of any such transfer and describe any change in processing that may result.

Cookies and Tracking Technologies

The tk668 platform uses cookies and similar tracking technologies to ensure the Platform functions correctly, to maintain your session while you are logged in, and to collect technical analytics data about how the Platform is used. Cookies are small text files placed on your device by your browser when you visit the Platform.

tk668 does not use third-party advertising cookies or cross-site tracking technologies. We do not build advertising profiles based on your browsing behaviour across other websites. The cookies used on the tk668 platform are limited to the following categories.

• Essential session cookies: these cookies are strictly necessary to operate the Platform. They maintain your logged-in state across pages, remember your language preference, and ensure that game data is correctly attributed to your account during a session. These cookies cannot be disabled without disrupting the functionality of the Platform.
• Performance and analytics cookies: these cookies collect anonymised data about how pages are accessed and which features are used most frequently. This information is used in aggregate to improve the Platform's performance and mobile experience. No individually identifying data is associated with these cookies.
• Security cookies: these cookies support fraud detection and session integrity functions. They help tk668 identify unusual login patterns, detect potential account compromise, and protect against automated attacks. They operate silently and do not collect browsing data from other websites.

Data Retention

tk668 retains your personal data for as long as your account is active and for a period thereafter as required by applicable law and our operational needs. Specifically: registration data and identity verification documents are retained for a minimum of 5 years from the date of account closure; transaction records are retained for a minimum of 5 years from the date of the transaction; gaming activity records are retained for a minimum of 3 years from the date of the activity; customer support communications are retained for 2 years from the date of the communication.

Where you request deletion of your personal data, we will action that request to the fullest extent permitted by law. Some data — particularly transaction records and identity verification documents — must be retained for the minimum statutory periods described above regardless of your deletion request, in order to comply with anti-money-laundering obligations and to resolve any disputes that arise after account closure. We will confirm in writing which data has been deleted and which has been retained, and the reason for any retention beyond your request.

Your Rights Over Your Personal Data

As a tk668 player, you have the following rights in relation to your personal data. To exercise any of these rights, please contact the tk668 support team. We will respond to all verified rights requests within 30 days of receipt.

• Right of access: you have the right to request a copy of all personal data we hold about you. We will provide this in a commonly used format within 30 days of a verified request.
• Right of rectification: if any personal data we hold about you is inaccurate or incomplete, you have the right to request that we correct or complete it. Corrections to registered account details (such as your name or mobile number) may require identity verification before they are applied.
• Right to erasure: subject to our legal retention obligations, you have the right to request deletion of your personal data. See the Data Retention section above for details of what may and may not be deleted in response to such a request.
• Right to restrict processing: you have the right to request that we restrict the processing of your personal data in certain circumstances — for example, where you contest the accuracy of the data or where you have objected to processing based on legitimate interests and the objection is pending consideration.
• Right to withdraw consent: where we process your personal data on the basis of your consent (for example, to send you promotional communications), you may withdraw that consent at any time. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

To exercise any of the rights described above, please contact the tk668 support team at [email protected]. All rights requests must be submitted from the email address or mobile number registered to your account so that we can verify your identity before processing the request. We do not charge a fee for rights requests unless they are manifestly unfounded or excessive.

Security Measures

tk668 implements a range of technical and organisational security measures designed to protect your personal data against unauthorised access, accidental loss, destruction, or disclosure. These measures include SSL encryption on all data transmissions, restricted access controls so that only authorised staff can access personal data on a need-to-know basis, regular security assessments of Platform infrastructure, and secure storage of identity verification documents with access logging.

Despite these measures, no online platform can guarantee absolute security against all possible threats. In the event of a personal data breach that is likely to result in a risk to your rights and freedoms, tk668 will notify affected players without undue delay and will take all reasonable steps to contain and remediate the breach. We will also notify relevant authorities where required by applicable law.

Changes to This Privacy Policy

tk668 may update this Privacy Policy from time to time to reflect changes in applicable law, our data processing practices, or the services we offer. Where we make a material change to this Policy, we will notify active players via the mobile number or contact details registered to their account, or by displaying a prominent notice on the Platform, at least 7 days before the change takes effect.

The most current version of this Policy is always available at tk668.bio/privacy-policy, and the date of the most recent update is shown at the top of this page. Continued use of the Platform following any update to this Policy constitutes your acceptance of the revised Policy. If you do not agree with any change, you must stop using the Platform and may request account closure by contacting tk668 support.
