At tk3666, your privacy is a core responsibility, not an afterthought. This Privacy Policy explains in plain terms what personal data we collect, why we collect it, how it is used, and the rights you hold over your own information as a Player on our platform.
These six principles summarise our approach to data privacy. The full legal detail is in the policy document below.
We only collect data that is genuinely necessary to provide, secure, and improve our services.
All personal data is stored on encrypted servers. Access is restricted to authorised personnel only.
Your personal information is never sold or rented to third-party marketing companies or data brokers.
Access, correct, or request deletion of your data at any time by contacting our support team.
Data shared with third parties is limited to what is strictly required to process payments and verify identity.
Personal data is retained only as long as necessary for the purposes it was collected, then securely deleted.
tk3666 ("we", "us", "our") operates the online casino and sports betting platform accessible at tk3666.biz (the "Platform"). This Privacy Policy sets out the basis on which personal data collected from our Players, visitors, and users ("you", "your") will be processed by us. Please read this policy carefully to understand our practices regarding your personal data.
This Privacy Policy applies to all personal data collected through your use of the Platform, including data provided during account registration, identity verification, deposits and withdrawals, customer support interactions, and your general browsing activity on tk3666.biz.
tk3666 is committed to handling your personal data with the highest standards of care and transparency. We operate a platform designed for the Bangladesh market, serving Players who communicate primarily in English, and we apply data protection principles consistent with internationally recognised best practices to ensure your information is treated responsibly at every stage of its lifecycle.
By registering an Account on the Platform, depositing funds, placing a wager, or simply browsing tk3666.biz, you acknowledge that you have read and understood this Privacy Policy and you consent to the processing of your personal data as described herein. If you do not agree with any part of this policy, you should cease using the Platform and contact us at [email protected] to request Account closure.

tk3666 will not use your personal data to make fully automated decisions that produce significant legal or similarly significant effects on you without providing a means for human review. Where automated processing is used (e.g., fraud detection flags), a human compliance team member will review any outcome before an adverse action such as Account suspension is taken.
tk3666 processes your personal data on one or more of the following legal bases:
tk3666 does not sell or rent your personal data to any third party. We share your data only in the limited circumstances described below, and only to the extent necessary for the stated purpose.
We share the minimum necessary financial data with bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, and other payment partners to facilitate deposits and withdrawals. These providers process payment data under their own privacy terms and are not permitted to use the data for any purpose other than processing the transaction.
When you play a game on the Platform, your session data (Player ID, wager amounts, game round IDs) is shared with the relevant Game Provider (e.g., Pragmatic Play, Evolution Gaming, Spribe) to deliver the game and record outcomes. Game Providers are not provided with your full personal profile.
To assist with KYC compliance, tk3666 may use a third-party identity verification service. Documents you submit for KYC purposes may be transmitted to and processed by such a partner, which is bound by confidentiality obligations and data processing agreements with tk3666.
tk3666 may disclose personal data to competent government authorities, law enforcement agencies, or courts where we are legally required to do so, or where we reasonably believe disclosure is necessary to protect the rights, property, or safety of tk3666, our Players, or the public.
In the event of a merger, acquisition, restructuring, or sale of all or substantially all of tk3666's assets, your personal data may be transferred to the relevant successor entity. We will notify registered Players via email in advance of any such transfer where it materially affects their data rights.
tk3666 uses cookies and similar tracking technologies to operate the Platform effectively and to understand how Players use our services. A cookie is a small text file placed on your device when you visit a website. Cookies cannot execute programs or deliver viruses; they are solely used to store information that helps the Platform function and improve over time.
| Cookie Type | Purpose | Duration |
|---|---|---|
| Strictly Necessary | Maintain your login session, remember your Account state, enable core Platform functions | Session / up to 24 hours |
| Functional | Remember your language preference (English), display settings, and responsible gaming limit preferences | Up to 30 days |
| Analytics | Aggregate data on page visits, session duration, and navigation patterns to help us improve the Platform (data anonymised) | Up to 12 months |
| Security | Detect fraudulent activity, bot access, and suspicious login patterns | Session-based |
You can control and manage cookies through your browser settings. Most browsers allow you to refuse new cookies, delete existing cookies, and set preferences for specific websites. Please note that disabling strictly necessary cookies will impair the functionality of tk3666.biz and may prevent you from logging in or completing transactions. Disabling functional and analytics cookies will not prevent you from using the Platform but may affect your experience.
tk3666 does not use third-party advertising cookies or behavioural tracking cookies that profile you for the benefit of third-party advertisers.
tk3666 takes the security of your personal data seriously and implements a range of technical and organisational measures to protect it from unauthorised access, loss, alteration, disclosure, or destruction.
tk3666 retains personal data only for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable legal, regulatory, or contractual obligations. The following retention periods apply as a general guide:
| Data Category | Retention Period | Reason |
|---|---|---|
| Account and registration data | Duration of account + 5 years after closure | Legal obligation, dispute resolution |
| KYC / identity documents | 5 years from date of collection | Anti-money laundering compliance |
| Financial transaction records | 7 years from transaction date | Financial record-keeping obligations |
| Betting and game history | 5 years from the date of the session | Dispute resolution, responsible gaming audit |
| Customer support communications | 3 years from the date of the interaction | Quality assurance, complaint handling |
| Technical / server logs | Up to 12 months | Security monitoring, fraud detection |
| Self-exclusion records | Permanent (or until formal request for removal post-exclusion period) | Responsible gaming safeguarding |
When a retention period expires and there is no overriding legal basis for continued storage, tk3666 will securely delete or anonymise the personal data concerned. Anonymised data (from which no individual can be identified) may be retained indefinitely for statistical and analytical purposes.
As a Player whose personal data is processed by tk3666, you hold the following rights with respect to that data. To exercise any of these rights, please contact us at [email protected] with the subject line "Data Rights Request" and your registered Account username.
If you are a parent or guardian and you believe that your child has provided personal data to tk3666 without your consent, please contact us immediately at [email protected]. We will investigate and take appropriate action within 48 hours of receiving your report.
tk3666 encourages parents and guardians to make use of parental control software and filtering tools to prevent minors from accessing online gambling platforms. We support responsible gaming education and work to ensure that our age verification processes are as robust as possible.
The tk3666 Platform may contain references to, or visual branding of, third-party service providers such as payment partners (bKash, Nagad, Rocket) and game providers (Pragmatic Play, Evolution Gaming, Spribe, etc.). While we integrate with these services operationally, tk3666 does not control the privacy practices of these third parties and is not responsible for their data handling.
When you interact with a third-party payment service (for example, completing a bKash transaction to deposit funds), the data you provide directly to that third-party service is governed by their own privacy policy. tk3666 receives only the transaction confirmation data described in Section 3 of this policy.
Game content delivered by third-party game providers is governed by those providers' own terms of service regarding data collected within their game environments. tk3666 provides only the Player ID and session parameters necessary to launch the game; the game provider's platform handles the remainder of the game session independently.
tk3666 reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data practices, legal obligations, or the services we offer. The effective date at the top of this document will be updated whenever material changes are made.
Where changes are material — meaning they meaningfully affect how we collect, use, or share your personal data — tk3666 will notify registered Players via the email address associated with their Account at least 14 days before the changes take effect. For non-material changes, the updated policy will be published on this page without advance notice.
Your continued use of the Platform following the effective date of any revised Privacy Policy constitutes your acceptance of the updated terms. If you do not agree with the changes, you should cease using the Platform before the effective date and contact us to close your Account.
If you have any questions, concerns, or requests relating to this Privacy Policy or tk3666's data practices, please reach our support team using the details below. We are available around the clock to assist you.
