Privacy Policy — btk11
At btk11, the privacy and security of your personal data are treated with the same seriousness as the security of your account funds. This Privacy Policy explains precisely what data btk11 collects from players in Bangladesh, why it is collected, how it is stored and protected, and what rights you hold over your own information. Please read this document carefully alongside our Terms & Conditions.
Our Core Privacy Commitments
Every interaction between your browser and btk11.app is protected by SSL (Secure Sockets Layer) encryption. This prevents unauthorised interception of your account details, payment information, and personal data in transit.
btk11 does not sell, rent, or trade your personal information to third-party marketers or data brokers. Your data is used solely for the purposes outlined in this Privacy Policy — operating the btk11 platform and keeping it secure.
You have the right to access, correct, or request deletion of your personal data held by btk11. Requests can be submitted to [email protected] at any time, and btk11 will respond within a reasonable timeframe consistent with applicable data protection obligations.
Payment details including bKash, Nagad, Rocket, and Upay mobile numbers and bank account identifiers are used exclusively for processing your deposits and withdrawals. btk11 does not store full card numbers; card transactions are handled directly by PCI-DSS compliant payment processors.
btk11 uses cookies and similar tracking technologies to maintain your session, remember your preferences, and analyse platform performance. You can manage your cookie preferences through your browser settings. Essential session cookies cannot be disabled without affecting platform functionality.
btk11 retains your personal data only for as long as necessary to provide the platform's services and to meet applicable legal and anti-money laundering (AML) compliance obligations. Once the retention period has elapsed, data is securely deleted or anonymised.
Data We Collect
btk11 collects personal data from you in several ways: directly when you register an account or contact support; automatically as you use the btk11 platform; and, in some circumstances, from third-party service providers who assist in identity verification or payment processing. The categories of data collected are described below.
Data You Provide Directly
When you register a btk11 account or interact with the platform's features, you may provide the following categories of personal data:
| Data Category | Examples | Purpose |
|---|---|---|
| Identity Data | Full name, date of birth, NID number | KYC verification, age confirmation, fraud prevention |

| Communications Data | Support chat transcripts, emails sent to btk11 | Customer support, dispute resolution, quality assurance |
| Identity Documents | NID scan, passport copy, utility bill (for KYC) | Age and identity verification per AML obligations |
Data Collected Automatically
When you access and use the btk11 platform, certain technical and behavioural data is collected automatically by our systems. This data does not typically identify you by name but forms part of your account profile and is used to maintain platform security and improve user experience:
- Device data: Device type, operating system, browser type and version, screen resolution, and device identifiers.
- Network data: IP address, approximate geographic location derived from IP, internet service provider (ISP) identity.
- Session data: Pages visited on btk11.app, time spent on each page, game sessions initiated, bets placed, features used, and session timestamps in Bangladesh Standard Time (BST, UTC+6).
- Cookie and tracking data: Session cookies, preference cookies, and analytics identifiers. See Section 4 for full cookie details.
How We Use Your Data
btk11 processes your personal data only for clearly defined, lawful purposes. We do not use your data in ways that are incompatible with the purposes for which it was originally collected. The primary purposes for which btk11 processes personal data are as follows:
Platform Operation & Account Management
Your identity, contact, and credential data are used to create and maintain your btk11 account, authenticate your logins, process your bets and casino gameplay, and manage your deposit and withdrawal requests. Without this processing, btk11 cannot provide its core services to you. This processing is necessary for the performance of our contractual obligations to you as a registered player.
Identity Verification & Compliance
btk11 is legally and operationally obligated to verify the identity and age of all registered players. Your identity documents and personal details are processed to fulfil Know Your Customer (KYC) requirements and to comply with applicable anti-money laundering (AML) obligations. This processing is carried out on the basis of legal obligation. btk11 may be required to share relevant data with law enforcement or regulatory bodies where legally compelled to do so.
Security & Fraud Prevention
Technical data including IP addresses, device identifiers, and session patterns are analysed by btk11's security systems to detect and prevent unauthorised account access, bonus abuse, account takeover attempts, and other fraudulent activity. This processing is carried out on the basis of btk11's legitimate interest in protecting the platform's integrity and the financial security of all registered players.
Customer Support
When you contact the btk11 support team at [email protected], the communications you send — including your name, account details, and the substance of your query — are processed to resolve your support request and to maintain a record of the interaction for quality assurance and dispute resolution purposes.
Responsible Gaming Monitoring
btk11 uses gameplay and session data to monitor for indicators of problem gambling behaviour, such as unusually extended session durations, rapid escalation of bet sizes, or frequent self-exclusion override requests. This monitoring is carried out in the interests of player welfare and supports btk11's responsible gaming programme described at btk11.app/responsible-gaming.
Promotional Communications
Where you have opted in to receive marketing communications, btk11 may use your email address and registered preferences to send you information about promotions, bonuses, and platform updates that are relevant to your interests as a btk11 player. You may withdraw your consent to marketing communications at any time by contacting [email protected] or by using the unsubscribe mechanism included in each marketing email.
Data Sharing & Third Parties
btk11 does not sell your personal data to third parties. However, in order to operate the platform effectively and to meet legal obligations, btk11 shares certain categories of personal data with carefully selected third-party service providers and, where legally required, with public authorities. All third parties with whom btk11 shares personal data are contractually required to handle that data securely and to use it only for the specific purpose for which it was shared.
Payment Processing Partners
To process your deposits and withdrawals, btk11 shares the minimum necessary payment data with its payment processing partners. This includes mobile financial service providers bKash, Nagad, Rocket, and Upay, as well as banking partners such as Dutch-Bangla Bank and City Bank, and international card schemes Visa and Mastercard. These partners process your financial data under their own privacy policies and applicable financial regulation. btk11 does not store full card numbers on its own systems.
Identity Verification Providers
btk11 may use third-party KYC and identity verification service providers to assist in verifying the identity documents submitted by players during the account verification process. These providers receive only the specific documents and personal data required for verification and are not permitted to use this data for any other purpose.
Game Technology Providers
Game content on btk11 is supplied by third-party game providers including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. These providers may receive anonymised or pseudonymised game session data to support game delivery, RNG certification, and technical support. Personal identity data is not shared with game providers for game delivery purposes.
Legal Disclosure
btk11 may disclose your personal data to law enforcement agencies, regulatory authorities, or courts where required to do so by applicable law, court order, or other binding legal instrument. In such cases, btk11 will disclose only the minimum data required to satisfy the legal obligation and will, where legally permissible, notify you that such a disclosure has been made.
Cookies & Tracking Technologies
btk11.app uses cookies and similar tracking technologies to ensure the platform functions correctly, to remember your preferences, and to understand how players interact with the platform so that the user experience can be continuously improved. The table below describes the categories of cookies used on btk11.app.
| Cookie Type | Purpose | Can Be Disabled? |

Managing Your Cookie Preferences
Most modern browsers allow you to control cookies through their settings panels. You can typically choose to block all third-party cookies, delete existing cookies, or receive a notification before a cookie is stored. Please note that disabling essential or security cookies will impair your ability to log in to your btk11 account and use the platform's features. For guidance on managing cookies in your specific browser, refer to the help documentation provided by your browser's publisher.
btk11 does not use cookies to track your activity on other websites or to build advertising profiles. The cookies deployed on btk11.app relate exclusively to the operation and improvement of the btk11 platform itself.
Data Retention & Storage
btk11 retains your personal data for as long as is necessary to fulfil the purposes described in this Privacy Policy, or for as long as is required by applicable legal and compliance obligations, whichever is longer. The following retention periods apply to the main categories of personal data held by btk11:
- Account and identity data: Retained for the duration of your active account relationship with btk11, plus a minimum of five (5) years following account closure to satisfy AML record-keeping obligations.
- Transaction records (deposits and withdrawals): Retained for a minimum of five (5) years from the date of each transaction, in line with financial record-keeping requirements.
- KYC identity documents: Retained for the duration of your account plus five (5) years following account closure, or for longer where required by a specific legal obligation or ongoing investigation.
- Customer support communications: Retained for three (3) years from the date of the communication to support dispute resolution and quality assurance review.
- Marketing preferences and consent records: Retained for the duration of your consent plus three (3) years, to demonstrate compliance with consent obligations.
- Technical and session logs: Retained for up to ninety (90) days for security monitoring and fraud detection purposes, after which they are automatically deleted or anonymised.
Data Storage Location
btk11's platform data is stored on secure servers. Where data is processed or stored by third-party service providers outside of Bangladesh, btk11 ensures that appropriate contractual safeguards are in place to protect the security and confidentiality of your data in accordance with applicable data protection standards.
Your Privacy Rights
As a btk11 player, you hold a number of rights in relation to the personal data that btk11 holds about you. These rights are described below. To exercise any of these rights, please contact the btk11 support team in writing at [email protected]. btk11 will acknowledge your request within three (3) business days and provide a substantive response within fourteen (14) business days, measured during Bangladesh Standard Time (BST, UTC+6) business hours.
Right of Access
You have the right to request a copy of the personal data that btk11 holds about you. This is sometimes called a Subject Access Request (SAR). btk11 will provide you with a summary of the data held, the purposes for which it is processed, and the categories of third parties with whom it has been shared, in a clear and readable format.
Right to Rectification
If you believe that any personal data btk11 holds about you is inaccurate or incomplete, you have the right to request that it be corrected. Please note that corrections to identity data may require additional verification documentation to ensure the integrity of your account record.
Right to Erasure
You may request that btk11 delete your personal data. btk11 will action erasure requests where the data is no longer necessary for the purposes for which it was collected and where no overriding legal obligation requires its continued retention. Where a legal retention obligation applies (such as AML record-keeping requirements), btk11 will explain why full erasure cannot be completed immediately and will confirm when the data will be deleted at the end of the applicable retention period.
Right to Restriction of Processing
You may request that btk11 restrict the processing of your personal data in certain circumstances — for example, while the accuracy of data is being contested, or while an objection to processing is being assessed. During a restriction period, btk11 will continue to store your data but will not actively process it for purposes beyond storage and legal compliance.
Right to Object to Processing
Where btk11 processes your personal data on the basis of legitimate interests — such as fraud detection or marketing analytics — you have the right to object to that processing. btk11 will assess your objection and will cease the relevant processing unless it can demonstrate compelling legitimate grounds that override your interests and rights.
Right to Withdraw Marketing Consent
Where btk11 sends you promotional communications based on your consent, you may withdraw that consent at any time by emailing [email protected] with the subject line "Unsubscribe from Marketing" or by using the unsubscribe link included in each marketing email. Withdrawal of marketing consent does not affect the lawfulness of processing carried out before the withdrawal.
Data Security Measures
btk11 implements a range of technical and organisational security measures designed to protect your personal data against unauthorised access, accidental loss, alteration, disclosure, or destruction. While no online platform can guarantee absolute security against all possible threats, btk11's security programme reflects industry best practices for online gaming and financial services platforms operating in the Bangladesh market and internationally.
Technical Safeguards
- SSL / TLS Encryption: All data transmitted between your device and btk11.app is encrypted using SSL/TLS protocols, preventing interception of your data in transit.
- Password Hashing: Account passwords are never stored in plain text. btk11 uses industry-standard cryptographic hashing algorithms to store password data, meaning that even btk11 staff cannot retrieve your original password.
- Access Controls: Access to personal data within btk11's internal systems is restricted on a strict need-to-know basis. Staff members can only access the specific data necessary for their role.
- Intrusion Detection: btk11's platform infrastructure is monitored by automated intrusion detection and threat response systems that identify and contain potential security incidents in real time.
- Secure Payment Handling: Card payment data is handled by PCI-DSS compliant payment processors. btk11 does not store full card numbers on its own servers.
Organisational Safeguards
- All btk11 staff who handle personal data are subject to confidentiality obligations and receive regular data protection and security training.
- Third-party service providers with access to personal data are vetted for security compliance before engagement and are contractually required to maintain appropriate security standards.
- btk11 conducts periodic internal reviews of its data security practices to identify and address emerging risks.
Security Incident Response
In the event of a personal data breach that is likely to result in a risk to your rights or interests, btk11 will take immediate steps to contain the breach, assess its scope and impact, and notify affected players via their registered email address as promptly as practicable. btk11 will also fulfil any applicable legal obligations in relation to breach notification.
If you suspect that your btk11 account has been accessed without your authorisation, or if you believe your personal data may have been compromised in connection with your use of btk11, please contact the support team immediately at [email protected] so that appropriate protective action can be taken without delay.
