Privacy Policy
How tk11b Handles Your Data
Your privacy matters to tk11b. This Privacy Policy explains exactly what personal information we collect when you use our platform, why we collect it, how it is stored and protected, and the rights you hold over your own data. We are committed to full transparency in every aspect of data handling.
01 Information We Collect
When you register and use the tk11b platform, we collect personal information that is necessary to operate a safe, compliant, and functional online betting and casino service for users in Bangladesh. We collect information directly from you, automatically through your use of the platform, and, where required, from trusted third-party verification partners.

| Financial Data | bKash / Nagad / Rocket / Upay account numbers, bank account details (Dutch-Bangla Bank, City Bank, BRAC Bank, Islami Bank, Sonali Bank), Visa/Mastercard partial details | Deposit & withdrawal setup |

Information Collected Automatically
In addition to information you actively provide, tk11b automatically collects the following technical and behavioural data when you access our platform via mobile browser, desktop browser, or any other interface:
- IP address and approximate geographic location (city/region level, not precise GPS coordinates)
- Device type, operating system, and browser version
- Session timestamps, pages visited, features used, and duration of activity
- Betting history, game session data, wagering patterns, and bonus redemption activity
- Deposit and withdrawal transaction records, including timestamps, amounts in BDT, and payment method identifiers
- Referral source (the URL or channel through which you arrived at tk11b)
- Cookie identifiers and similar tracking tokens — see Section 5 for full cookie details
02 How We Use Your Data
tk11b uses the personal data we collect for clearly defined purposes only. We do not sell your personal data to third parties for their own marketing purposes. Every data use described below is tied to a specific operational, legal, or security need of the platform.
- Account Setup and Management: Your identity, contact, and credential data is used to create and maintain your tk11b account, authenticate your login sessions, and communicate important account updates to your registered mobile number or email address.
- Age and Identity Verification: We use identity documents and date-of-birth data to confirm that all users are aged 18 or above before allowing access to betting and casino products. This is a non-negotiable requirement and forms a core part of our responsible gaming commitment.
- Payment Processing: Financial data linked to bKash, Nagad, Rocket, Upay, and bank accounts is used exclusively for processing deposits to and withdrawals from your tk11b account in Bangladeshi Taka (BDT). We do not store full card numbers; only tokenised references are retained.
- Platform Personalisation: Behavioural and session data is used to surface relevant cricket odds, BPL and IPL betting markets, slot game recommendations, and live casino tables that align with your demonstrated preferences.
- Fraud Prevention and Security: IP addresses, device fingerprints, and transaction patterns are analysed continuously to detect and prevent unauthorised account access, multi-accounting, bonus abuse, money laundering, and other prohibited conduct.
- Regulatory Compliance: Where required by applicable law or in response to a lawful authority request, we may use and disclose your data to comply with legal obligations including anti-money laundering (AML) obligations.
- Customer Support: Communications data — including support tickets and email correspondence — is used to resolve account queries, process withdrawal disputes, and respond to responsible gaming requests.
- Platform Improvement: Aggregated and anonymised session and usage data is used to improve the tk11b platform, fix technical issues, and develop new product features.
- Promotional Communications: Where you have opted in to marketing communications, your contact data is used to notify you of seasonal promotions, bonus offers, and major sporting events such as the BPL, IPL, T20 World Cup, and ICC tournaments. You may opt out at any time via your account settings.
03 Legal Basis for Processing
tk11b processes your personal data on one or more of the following legal bases depending on the specific purpose for which the data is used:
| Processing Purpose | Legal Basis |
|---|---|
| Account registration and management | Performance of contract (you have agreed to our Terms & Conditions) |
| Age and identity verification (KYC) | Legal obligation; Legitimate interest in protecting minors |
| Payment processing (deposits and withdrawals) | Performance of contract |
| Fraud detection and security monitoring | Legitimate interest in protecting the platform and all users |
| AML compliance and regulatory reporting | Legal obligation |
| Marketing communications | Consent (opt-in); withdrawable at any time |
| Platform analytics and improvement | Legitimate interest in operating and improving our service |
| Responsible gaming monitoring | Legal obligation; Legitimate interest in user welfare |
Where processing is based on consent, you have the right to withdraw that consent at any time without affecting the lawfulness of processing carried out prior to withdrawal. Withdrawal of consent for essential processing purposes — such as identity verification — may result in account restriction, as these functions are integral to legal and safe operation of the platform.
04 Data Sharing & Disclosure
tk11b does not sell, rent, or trade your personal data to any third party for commercial gain. We share your data only where strictly necessary for the operation of our platform or where we are required to do so by law. The following categories of third parties may receive limited personal data for specific, defined purposes:
Payment Processors
To process deposits and withdrawals, we share relevant financial identifiers with bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, BRAC Bank, Islami Bank, Sonali Bank, Visa, and Mastercard processing networks. Only the minimum data required to complete a specific transaction is shared with each payment partner. We do not share your full betting history or identity documents with payment partners.
Identity Verification Partners
To fulfil our Know Your Customer (KYC) and age verification obligations, we may use trusted third-party identity verification services. These services receive only the verification documents necessary to confirm identity and age, and are contractually bound to process that data for verification purposes only.
Game Providers
The casino and slots content on tk11b is powered by certified third-party game providers including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. These providers receive a session token and an anonymised player identifier to deliver game content and record game session outcomes. Your full personal identity details are not shared with game providers.
Legal and Regulatory Authorities
tk11b will disclose personal data in response to a lawful and properly authorised request from a government body, law enforcement agency, or court of competent jurisdiction. We review all such requests carefully and disclose only the minimum data required to satisfy the legal obligation.
05 Cookies & Tracking Technologies
tk11b uses cookies and similar tracking technologies to operate the platform, maintain your login session, remember your preferences, and analyse how the platform is used. This section explains the types of cookies in use and your options for managing them.
What Are Cookies?
Cookies are small text files placed on your device by the tk11b web platform when you visit or log in. They allow the platform to recognise your device across page loads and sessions, maintain your authenticated state, and store lightweight preference data such as your preferred betting view or display language.
Cookie Categories Used by tk11b
| Cookie Type | Purpose | Duration |
|---|---|---|
| Strictly Necessary | Maintain your login session, secure your account token, enable core platform functions such as bet placement and deposit flow | Session |
| Functional | Remember your preferred odds format, saved betting slips, and display preferences | Up to 30 days |
| Analytics | Measure page views, feature usage, session duration, and navigation paths to improve the tk11b platform experience | Up to 12 months |
| Security | Detect and prevent suspicious login attempts, bot activity, and session hijacking | Session to 7 days |
Managing Cookies
Strictly necessary cookies cannot be disabled without significantly impairing platform functionality — disabling them will prevent you from logging in or placing bets. Functional and analytics cookies may be managed through your browser settings. Most modern browsers (Chrome, Firefox, Samsung Internet, and others commonly used by Bangladeshi mobile users) allow you to view, manage, and delete cookies through the browser's privacy or settings menu. Note that clearing cookies will log you out of your tk11b session and reset any saved preferences.
06 Data Retention
tk11b retains personal data for no longer than is necessary to fulfil the purpose for which it was collected or to comply with applicable legal retention obligations. The following retention periods apply as a general guide — specific regulatory requirements may mandate longer retention in certain categories:
- Active Account Data: Retained for the full duration of your active tk11b account relationship plus a minimum of five years following account closure, to satisfy AML record-keeping obligations.
- Transaction Records (Deposits and Withdrawals): Retained for a minimum of five years from the date of each transaction in accordance with financial record-keeping requirements.
- Identity Verification Documents (KYC): Retained for a minimum of five years from the date of verification or account closure, whichever is later.
- Customer Support Communications: Retained for three years from the date of the most recent communication in a given support case.
- Marketing Consent Records: Retained for the duration of your opted-in status plus two years following opt-out, to evidence that consent was properly obtained and withdrawn.
- Analytics and Session Data (Anonymised): Retained indefinitely in anonymised, aggregated form for platform improvement purposes. Individual session logs are deleted within 12 months.
- Closed Accounts — Responsible Gaming: Where an account is closed due to a self-exclusion request, a record of the self-exclusion decision is retained permanently to prevent re-registration in breach of the exclusion.
At the end of the applicable retention period, personal data is securely deleted or irreversibly anonymised. tk11b does not archive personal data beyond the periods described above unless required to do so by a lawful authority directive.
07 Your Data Rights
As a registered user of the tk11b platform, you hold the following rights with respect to your personal data. To exercise any of these rights, contact us at [email protected]. We will respond to all valid data rights requests within 30 days of receipt. In cases of complexity or high volume, we may extend this period by a further 30 days and will notify you accordingly.
- Right of Access: You may request a copy of all personal data we hold about you, along with a description of the purposes for which it is processed and the categories of third parties with whom it has been 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. You may also update much of your own account information directly through your account settings panel.
- Right to Erasure: You may request the deletion of your personal data where it is no longer necessary for the purpose for which it was collected, where you have withdrawn the consent on which processing was based, or where processing has been unlawful. This right is subject to any overriding legal retention obligations — for example, we cannot delete AML transaction records within the mandatory retention period.
- Right to Restrict Processing: In certain circumstances, you may request that we restrict the processing of your data while a query regarding its accuracy or the lawfulness of its processing is resolved.
- Right to Data Portability: Where processing is based on your consent or on the performance of a contract, and is carried out by automated means, you may request a copy of your data in a structured, commonly used, machine-readable format.
- Right to Object: You have the right to object to processing based on legitimate interest grounds, including profiling for platform personalisation purposes. You may opt out of marketing communications at any time via your account settings without affecting your ability to continue using the platform.
- Right to Withdraw Consent: Where processing is based on your consent, you may withdraw that consent at any time. Withdrawal will not affect the lawfulness of processing prior to the withdrawal date.
08 Data Security
tk11b takes the security of your personal data seriously and implements technical and organisational measures proportionate to the risk presented by the data we hold. The following security controls are in place across the tk11b platform:
- SSL/TLS Encryption: All data in transit between your device and the tk11b platform is encrypted using industry-standard SSL/TLS protocols. The padlock indicator in your browser confirms that your connection is secured.
- Password Hashing: Account passwords are never stored in plain text. They are hashed using a strong cryptographic algorithm before storage, meaning that even in the event of a data breach, your raw password cannot be recovered from the stored hash.
- Two-Step Verification (OTP): tk11b offers OTP-based two-step verification via your registered Bangladeshi mobile number. We strongly recommend all users enable this feature to significantly reduce the risk of unauthorised account access.
- Access Controls: Access to personal data within the tk11b organisation is restricted on a strict need-to-know basis. Staff members can only access the categories of data required to perform their specific role.
- Monitoring and Intrusion Detection: The platform operates continuous automated monitoring for suspicious access patterns, brute-force login attempts, and other security anomalies.
- Payment Data Security: Full payment card numbers are never stored on tk11b servers. Payment processing is handled via tokenised references managed by our certified payment partners. bKash, Nagad, and Rocket transactions are processed through the official APIs of those providers.
While tk11b implements robust security measures, no online platform can guarantee absolute security against all possible threats. You are responsible for maintaining the security of your account credentials and for notifying us immediately at [email protected] if you suspect any unauthorised activity on your account.
09 Third-Party Services
The tk11b platform integrates with a number of third-party services to deliver its full product range. This section describes how those integrations affect the handling of your personal data.
Game Content Providers
Casino and slot games on tk11b are provided by certified third-party studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. When you launch a game, a session is established with the relevant provider's game server using an anonymised session token. These providers' own privacy practices govern how they handle any data passed via that session token. tk11b does not pass your full name, NID details, or payment information to game providers.
Sports Data Feeds
Live cricket odds for BPL, IPL, T20 World Cup, and ICC events, as well as football and other sports markets, are powered by third-party sports data feed providers. These providers do not receive your personal data — the data flow is one-way (market data from the provider to tk11b) and your personal information plays no part in this integration.
Links from This Platform
The tk11b platform does not include links to external third-party websites. All navigation within the platform remains within the tk11b domain. This Privacy Policy does not apply to any third-party website that you may access independently of tk11b.
If you contact tk11b via email at [email protected], your email communications are handled by our email service infrastructure. Email messages related to account support are retained as described in the Data Retention section above and are accessible only to authorised support staff.
10 Policy Updates & Contact
tk11b reserves the right to update or amend this Privacy Policy at any time to reflect changes in our data practices, legal obligations, or platform features. When material changes are made — meaning changes that significantly affect how we use your personal data or the rights available to you — we will notify you via your registered email address or through an in-platform notification prior to the changes taking effect.
The effective date at the top of this page will always reflect the date on which the current version of the Privacy Policy came into force. We recommend reviewing this page periodically, particularly when you receive a notification of changes from the platform. Your continued use of tk11b following the publication of an updated Privacy Policy constitutes your acceptance of that updated policy.
