1 Introduction
tk688 ("tk688", "we", "us", "our") operates the online casino and sports betting platform accessible at tk-688.bio. This Privacy Policy ("Policy") describes the types of personal data we collect from players and visitors ("you", "your"), the purposes for which that data is used, the conditions under which it may be shared, and the rights available to you in relation to your personal information.
This Policy applies to all data collected through the tk688 website, mobile-optimised interface, live chat support system, and any other digital touchpoint operated by tk688. It does not apply to third-party websites or services that may be linked from the platform — those parties maintain their own privacy practices, for which tk688 accepts no responsibility.
We review and update this Policy periodically to reflect changes in our data practices, platform features, and applicable standards. The effective date of the most recent revision is shown at the top of this page. Continued use of the tk688 platform following an update constitutes your acknowledgement of the revised Policy.
2 Data We Collect
tk688 collects personal data through several channels: directly from you when you register an account or contact support, automatically through your use of the platform, and from third-party payment and identity verification partners. The categories of data we collect are detailed below.
| Category | Examples | Collection Method |
|---|---|---|
| Identity Data | Full legal name, date of birth, nationality, government-issued ID number | Registration form; KYC verification |
| Contact Data | Mobile phone number, email address, city of residence (e.g., Dhaka, Chittagong, Sylhet) | Registration form; support interactions |
| Financial Data | Mobile wallet account number (bKash, Nagad, Rocket, Upay), transaction amounts in BDT (৳), deposit and withdrawal history | Payment processor integration |
| Technical Data | IP address, device type, browser type and version, operating system, session timestamps | Automatic collection via platform logs |
| Usage Data | Pages visited, games played, bets placed, session duration, click paths | Automatic collection via analytics tools |
| Communications Data | Live chat transcripts, support ticket content, feedback messages | Support channel interactions |
| Verification Documents | Copies of National ID card, passport, or driving licence submitted during KYC | Uploaded by player during account verification |
We do not collect sensitive personal data such as racial or ethnic origin, political opinions, religious beliefs, biometric data (other than photo ID for age verification), or health information, unless you voluntarily disclose such information through a responsible gaming self-exclusion request.
3 How We Use Your Data
tk688 uses the personal data it collects solely for defined, legitimate purposes related to the operation of the platform and the delivery of services to players in Bangladesh. We do not use your data for any purpose that is incompatible with the purpose for which it was originally collected without first obtaining your explicit consent.
- Account creation and management: To register your account, verify your identity and age, maintain your account profile, and process password reset requests.
- Transaction processing: To facilitate deposits and withdrawals through bKash, Nagad, Rocket, and Upay, and to maintain an accurate record of your transaction history in BDT (৳).
- Platform security and fraud prevention: To detect and prevent unauthorised access, multiple account creation, bonus abuse, money laundering, and other fraudulent activity.
- Customer support: To respond to your queries, resolve disputes, and maintain a record of our communications with you for quality assurance and training purposes.
- Responsible gaming: To monitor betting patterns that may indicate problem gambling behaviour and to apply self-exclusion, deposit limits, or other protective measures at your request or at our discretion.
- Legal compliance: To comply with applicable anti-money laundering (AML) and know-your-customer (KYC) obligations, and to respond to lawful requests from regulatory or law enforcement authorities.
- Platform improvement: To analyse usage patterns and technical performance data so that we can improve the stability, speed, and content of the tk688 platform.
- Marketing communications: To send you promotional offers, bonus notifications, and seasonal promotions (such as BPL or Eid specials) where you have opted in to receive marketing messages. See Section 11 for opt-out options.
4 Legal Basis for Processing
Every data processing activity carried out by tk688 is grounded in one or more recognised legal bases. The primary legal bases under which tk688 processes personal data are as follows:
- Contractual necessity: Processing required to perform our obligations under the tk688 Terms and Conditions — including account registration, payment processing, and support services — is carried out on the basis that it is necessary to deliver the services you have requested.
- Legal obligation: Where we are required to process your data to comply with a legal requirement — such as KYC verification, AML reporting, or responding to a court order — we process that data on the basis of legal obligation.
- Legitimate interests: We process certain categories of data (particularly Technical Data and Usage Data) on the basis of tk688's legitimate interests in operating a secure, reliable, and commercially viable platform. We conduct a balancing test to ensure our legitimate interests do not override your fundamental privacy rights.
- Consent: Where processing is not required by contract or law, and where it is not covered by a legitimate interest assessment, we will request your explicit consent before processing. You have the right to withdraw consent at any time without affecting the lawfulness of processing carried out before withdrawal.
5 Data Sharing & Third Parties
tk688 does not sell, rent, or trade your personal data to any third party. Data is shared with external parties only where strictly necessary to deliver the platform's services, meet legal obligations, or protect the integrity of the platform. The categories of third parties with whom we may share your data are listed below.
- Payment processors: bKash, Nagad, Rocket, and Upay receive the minimum financial data required to process your deposit and withdrawal transactions. These partners operate under their own privacy policies and are bound by applicable financial services regulations.
- Game providers: Certified game studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Ezugi, and Spribe may receive anonymised session data to support game delivery and technical troubleshooting. No personally identifiable information is shared with game studios beyond what is technically necessary.
- Identity verification services: Where enhanced KYC verification is required, tk688 may engage a third-party identity verification provider to validate your government-issued documents. Such providers are contractually bound to process your data solely for verification purposes.
- Legal and regulatory authorities: tk688 may disclose personal data to law enforcement agencies, financial intelligence units, or other competent authorities where required by law or in response to a valid legal request. tk688 will not voluntarily disclose player data to any authority without a lawful basis for doing so.
- Platform infrastructure providers: Cloud hosting and content delivery partners may process data on our behalf as part of the technical infrastructure that supports the tk688 platform. All such providers are subject to data processing agreements that restrict their use of your data.
6 Cookies & Tracking Technologies
tk688 uses cookies and similar tracking technologies to support the operation of the platform, remember your session preferences, and gather aggregated usage analytics. Cookies are small text files stored on your device by your web browser when you visit the tk688 platform.
The types of cookies used by tk688 are as follows:
- Strictly necessary cookies: These are essential for the platform to function. They manage your login session, maintain your account state during a gaming session, and ensure security tokens are correctly applied. These cookies cannot be disabled without breaking platform functionality.
- Functional cookies: These cookies remember your preferences — such as your selected language, display settings, and last-used payment method — so you do not need to reconfigure these settings on each visit.
- Analytics cookies: These cookies collect aggregated, anonymised data about how players use the tk688 platform. This data helps us identify which features are popular, where technical issues arise, and how to improve the overall user experience. Analytics data is not linked to your personal account without your consent.
- Marketing cookies: Where you have opted in to promotional communications, these cookies help us deliver relevant offers and track the effectiveness of our campaigns. You can opt out of marketing cookies at any time — see Section 11.
You can manage cookie preferences through your browser settings. Please note that disabling strictly necessary cookies may prevent you from logging into your tk688 account or using certain platform features.
7 Data Retention
tk688 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 general retention periods applied by tk688 are as follows:
- Active account data (identity, contact, financial records): Retained for the lifetime of your account plus a minimum of five (5) years following account closure, in compliance with anti-money laundering record-keeping requirements.
- KYC and verification documents: Retained for a minimum of five (5) years from the date of submission or from the date of account closure, whichever is later.
- Transaction records: Retained for a minimum of five (5) years from the date of each transaction.
- Support communications: Live chat transcripts and email correspondence are retained for up to two (2) years from the date of the interaction.
- Technical and usage data: Anonymised aggregated analytics data may be retained indefinitely. Non-anonymised technical logs are retained for up to twelve (12) months.
- Marketing consent records: Retained for the duration of your opt-in period plus one (1) year after opt-out, as evidence of your consent or withdrawal.
When personal data is no longer required, it is securely deleted or irreversibly anonymised using industry-standard methods. Where deletion is not immediately possible due to technical constraints, the data is placed in a restricted, inaccessible state until secure deletion can be performed.
8 Data Security
tk688 implements a multi-layered security framework to protect your personal data against unauthorised access, disclosure, alteration, and destruction. Our security measures include, but are not limited to:
- 256-bit SSL/TLS encryption on all connections between your device and the tk688 platform — the same encryption standard used by major financial institutions.
- Encrypted storage of all account passwords using modern hashing algorithms. tk688 staff cannot view your password in plaintext at any time.
- Role-based access controls that restrict internal access to personal data to only those team members who require it to perform their job functions.
- Regular security audits and penetration testing to identify and address vulnerabilities before they can be exploited.
- Fraud detection systems that monitor transaction patterns and login behaviour in real time to flag suspicious activity.
- Secure data centres with physical access controls, redundant power supplies, and off-site backup procedures.
Despite these measures, no online platform can guarantee absolute security. In the event of a data breach that poses a material risk to your privacy, tk688 will notify affected players promptly and take all reasonable steps to contain and remediate the incident.
9 Your Rights
As a player on the tk688 platform, you have a number of rights in relation to the personal data we hold about you. These rights are summarised below. To exercise any of these rights, please contact our support team via live chat or by emailing [email protected] (plain text — not a clickable link).
- Right of access: You have the right to request a copy of the personal data that tk688 holds about you, along with information about how it is used and shared.
- Right to rectification: If any personal data we hold about you is inaccurate or incomplete, you have the right to request that it be corrected or updated.
- Right to erasure: You may request that tk688 delete your personal data where it is no longer necessary for the purposes for which it was collected, where you have withdrawn consent, or where the data has been processed unlawfully. Note that this right may be limited where retention is required by law (e.g., AML record-keeping obligations).
- Right to restriction of processing: In certain circumstances, you may request that tk688 restrict the processing of your personal data — for example, while a dispute about data accuracy is being resolved.
- Right to data portability: Where processing is based on your consent or on a contractual necessity, you may request that your personal data be provided to you in a structured, commonly used, machine-readable format.
- Right to object: You have the right to object to the processing of your personal data for direct marketing purposes at any time. You may also object to processing based on legitimate interests, subject to tk688's ability to demonstrate compelling grounds that override your interests.
- Right to withdraw consent: Where processing is based on your consent, you may withdraw that consent at any time. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.
tk688 will respond to all verified data rights requests within thirty (30) calendar days of receipt. Where a request is complex or numerous, this period may be extended by a further sixty (60) days, in which case we will notify you of the extension and the reason for it.
10 Children's Privacy
If you are a parent or guardian and believe that your child has accessed the tk688 platform or submitted personal data without your knowledge, please contact our support team immediately via live chat. We treat all such reports as a priority and will act swiftly to remove the data and close the account.
tk688 encourages parents and guardians in Bangladesh to make use of parental control software and mobile device management tools to restrict access to gambling platforms for individuals under the age of 18. For further guidance, please visit our Responsible Gaming page.
11 Marketing Communications
tk688 may send you promotional communications — including welcome bonus offers, reload promotions, free bet credits, and seasonal campaigns tied to events such as the BPL, IPL, T20 World Cup, Eid, or Pohela Boishakh — where you have opted in to receive such messages during account registration or through your account settings.
Marketing messages may be delivered via SMS to your registered mobile number or to your registered email address. tk688 will not send unsolicited promotional messages to individuals who have not opted in, and we will not sell your contact details to third-party marketing firms.
You may opt out of marketing communications at any time by:
- Updating your communication preferences in your tk688 account settings panel.
- Contacting tk688 support via live chat and requesting removal from the marketing list.
- Following the unsubscribe instructions included in any marketing email you receive from tk688.
Please note that opting out of marketing communications does not affect transactional messages — for example, deposit confirmation notifications, withdrawal status updates, or security alerts related to your account. These messages are essential to the operation of your account and cannot be disabled.

tk688 reserves the right to update or revise this Privacy Policy at any time to reflect changes in our data practices, platform features, legal obligations, or industry standards.
