Our Commitment

Privacy at the Core of bk664

bk664 is committed to safeguarding the personal information of every player who uses our platform. The six principles below summarise our approach to privacy — each one is applied consistently across our systems, processes, and third-party relationships.

Minimal Data Collection

bk664 collects only the information that is strictly necessary to deliver our services, verify player identity, process transactions, and comply with applicable obligations. We do not collect data speculatively or for undefined future purposes.

End-to-End Encryption

All data transmitted between your device and the bk664 platform is protected by 256-bit SSL/TLS encryption. Sensitive fields such as passwords and payment credentials are hashed or tokenised and never stored in plain text on our servers.

No Data Sales

bk664 does not sell, rent, or trade your personal information to advertisers, data brokers, or any unaffiliated third party for commercial purposes. Your data is used solely to operate, improve, and protect the bk664 service.

Player Control & Transparency

You have the right to access, correct, restrict, and request deletion of your personal data at any time. bk664 provides clear mechanisms to exercise these rights and will respond to all verified requests within a reasonable timeframe.

Controlled Third-Party Sharing

Where bk664 engages third-party service providers — such as KYC verification partners, payment processors, and game studios — those parties are contractually obligated to process your data only as instructed by bk664 and to maintain appropriate security standards.

Regular Policy Reviews

Privacy regulations and platform features evolve continuously. bk664 reviews this Privacy Policy at least once per year and updates it promptly whenever material changes occur. Players are notified of significant updates via their registered email address.

Section 1

Information We Collect

When you use the bk664 platform — whether browsing as a visitor, registering an account, depositing funds, placing wagers, or contacting our support team — we may collect several categories of personal information. The table below sets out each category, the specific data points involved, and the reason for collection.

All data collection by bk664 is purposeful. We do not collect data that has no defined use within our platform operations.

Category	Data Points Collected	Purpose
Identity Data	Full legal name, date of birth, National ID number, passport or driving licence details	Age verification, KYC compliance, prevention of duplicate accounts
Contact Data	Email address, mobile phone number, district or division (e.g., Dhaka, Chittagong, Sylhet)	Account communication, transaction alerts, responsible gaming notifications
Financial Data	Mobile wallet identifiers (bKash, Nagad, Rocket, Upay numbers), bank account reference data, transaction history, deposit and withdrawal amounts in ৳	Payment processing, anti-money-laundering review, withdrawal verification
Technical Data	IP address, device type and model, operating system, browser type and version, time zone (BST UTC+6)	Fraud detection, duplicate account identification, platform performance optimisation
Usage Data	Pages visited, games played, wager amounts, session duration, betting history, login timestamps	Service personalisation, responsible gaming monitoring, product improvement
Communications Data	Support chat transcripts, email correspondence, dispute records	Customer service delivery, complaint resolution, staff training quality assurance
Marketing Preferences	Opt-in/opt-out status for promotional communications, preferred game categories	Sending relevant promotions only to players who have consented to receive them

Data you provide directly. The majority of the personal data bk664 holds about you is information you provide voluntarily during account registration, KYC submission, payment setup, or when contacting our support team. You are not obligated to provide this information, but withholding mandatory fields (such as identity and age verification data) may prevent you from accessing certain platform features.

Data collected automatically. When you access the bk664 platform, certain technical and usage data is collected automatically via server logs, session tracking, and cookies. This data is used primarily for security, performance monitoring, and fraud prevention — not for building advertising profiles.

Data from third parties. In limited circumstances, bk664 may receive supplementary identity or risk-assessment data from KYC verification partners or payment processors. Any third-party data received is handled under the same standards as data collected directly, and is used only for the stated purpose.

Section 2

How We Use Your Data

bk664 uses personal data for a defined set of operational, legal, and service-improvement purposes. We do not use your data for any purpose that has not been disclosed in this Privacy Policy. The primary uses are as follows:

Account creation and management: To register your bk664 account, verify your identity and age, maintain your account settings, and manage your session securely across devices.
Payment processing: To facilitate deposits and withdrawals via bKash, Nagad, Rocket, Upay, and supported Bangladeshi bank accounts, and to maintain an accurate record of all financial transactions in your account history.
Platform delivery: To provide access to casino games, sports betting markets (including BPL, IPL, T20 World Cup), crash games, fishing games, and all other bk664 services in a stable, personalised manner.
Fraud prevention and security: To detect, investigate, and prevent duplicate accounts, unauthorised access, bonus abuse, money laundering, and other activities that breach our Terms & Conditions or applicable law.
Responsible gaming monitoring: To track betting patterns that may indicate problem gambling behaviour, to apply deposit limits or self-exclusion tools at a player's request, and to reach out proactively where our systems flag elevated risk indicators.
Customer support: To respond to your enquiries, resolve disputes, process complaints, and maintain a record of our interactions for service quality purposes.
Legal and regulatory compliance: To meet any obligations imposed by applicable law, including anti-money-laundering requirements, record-keeping obligations, and cooperation with lawful investigations by competent authorities.
Service improvement and analytics: To analyse aggregated, anonymised usage patterns across the bk664 platform to improve game selection, site navigation, and overall player experience. Individual-level data is not used for this purpose without appropriate anonymisation.
Marketing communications: To send promotional offers, bonus notifications, and platform updates — but only to players who have explicitly opted in to receive such communications. You may withdraw marketing consent at any time by contacting [email protected] (plain text — not a clickable link).

bk664 does not use automated decision-making (including profiling) that produces legal or similarly significant effects on players without human review. Where automated tools assist in fraud or risk assessment, a human agent reviews outcomes before any account action is taken.

Section 3

Legal Basis for Processing

bk664 processes personal data only where a valid legal basis exists for doing so. Depending on the nature of the processing activity, one or more of the following legal bases applies:

Contractual necessity: Processing that is required to fulfil the contract between you and bk664 — specifically, the account registration agreement and the Terms & Conditions you accepted when joining the platform. Without this processing, bk664 cannot deliver the services you have signed up to receive.
Legal obligation: Processing that bk664 is required to perform in order to comply with applicable laws and regulations, including anti-money-laundering obligations, age verification requirements, and data retention mandates.
Legitimate interests: Processing carried out to pursue bk664's legitimate business interests — such as fraud prevention, platform security, and service improvement — provided those interests are not overridden by your own privacy rights and interests. bk664 conducts a proportionality assessment before relying on this basis.
Consent: Processing of optional data categories — primarily marketing communications and certain cookie-based tracking — where you have given freely, specific, informed, and unambiguous consent. You may withdraw consent at any time without affecting the lawfulness of prior processing.

Where bk664 relies on legitimate interests as the legal basis, you have the right to object to that processing. To exercise this right, contact the bk664 privacy team at [email protected] (plain text — not a clickable link) with the subject "Privacy Objection". bk664 will review your objection and cease the relevant processing unless compelling legitimate grounds exist that override your interests, rights, and freedoms.

Section 4

Data Sharing & Disclosure

bk664 does not sell your personal data. We share personal information only in the limited circumstances described below, and always subject to appropriate contractual or legal safeguards:

Payment processors and mobile wallet providers: Transaction data (including mobile wallet identifiers and ৳ amounts) is shared with bKash, Nagad, Rocket, Upay, and supported banks solely to process your deposits and withdrawals. These providers operate under their own privacy policies and are independently regulated.
KYC and identity verification partners: Identity documents and related personal data may be shared with accredited third-party KYC verification services to confirm your age and identity as required. These partners are contractually bound to use your data only for verification purposes and to delete it once the process is complete.
Game providers and studios: Certain technical session data (such as your player ID, game session identifiers, and wager results) is shared with game providers including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi to deliver their games on the bk664 platform. These providers do not receive your contact or financial data.
Fraud prevention and security services: Aggregated technical and behavioural data may be shared with specialist fraud-detection providers to identify suspicious activity patterns. Individual personal data shared in this context is minimised and subject to strict processing restrictions.
Legal and regulatory authorities: bk664 may disclose personal data to competent courts, regulators, law enforcement bodies, or other authorities where required to do so by law, or where disclosure is necessary to protect the rights, property, or safety of bk664, its players, or the public.
Corporate transactions: In the event of a merger, acquisition, or transfer of bk664's business operations, personal data held by bk664 may be transferred to the acquiring entity, subject to the same privacy protections as set out in this Policy. Affected players will be notified in advance where legally permissible.

No cross-border data sales. bk664 does not transfer or sell your personal data to foreign advertising networks, data brokers, or marketing companies. Any international transfer of data — for example, to a game provider's servers located outside Bangladesh — is conducted under contractual data protection clauses that maintain the same standard of protection as this Policy.

Section 5

Cookies & Tracking Technologies

bk664 uses cookies and similar tracking technologies to operate the platform, maintain your session, remember your preferences, and analyse aggregate usage patterns. The following cookie categories are in use:

Cookie Type	Purpose	Duration
Strictly Necessary	Essential for the platform to function — maintains your login session, remembers your language preference, and prevents cross-site request forgery (CSRF). Cannot be disabled without breaking core platform functionality.	Session / up to 24 hours
Performance & Analytics	Collects anonymised data on page load times, error rates, and navigation paths to help bk664 identify and resolve technical issues and improve the overall player experience.	Up to 12 months
Functional	Remembers your display preferences, previously visited game categories, and table/slot filter settings so the platform feels personalised on return visits.	Up to 6 months
Security & Fraud Prevention	Supports device fingerprinting and session consistency checks used to detect account takeover attempts, bot activity, and suspicious login patterns.	Up to 30 days

Managing cookies. You can control cookie settings through your browser preferences. Most modern browsers allow you to block or delete cookies on a per-site or global basis. Note that disabling strictly necessary cookies will impair your ability to log in and use the bk664 platform. Disabling performance or functional cookies will not prevent access but may reduce the quality of your experience.

No third-party advertising cookies. bk664 does not use cookies from third-party advertising networks or social media platforms for the purpose of tracking you across other websites or building advertising profiles. Our use of tracking technologies is limited to operating and improving the bk664 platform itself.

Do Not Track. Some browsers send a "Do Not Track" (DNT) signal to websites. bk664 respects the intent of DNT signals — where a DNT signal is detected, bk664 limits tracking to strictly necessary cookies only and disables all non-essential analytics and functional cookies for that session.

Section 6

Data Retention

bk664 retains personal data only for as long as is necessary to fulfil the purpose for which it was collected, or as required by applicable legal, regulatory, or operational obligations. The following retention periods apply as a general guide:

Active account data: All personal and transactional data associated with an active bk664 account is retained for the duration of the account's active status. This includes identity records, payment history, and betting activity logs.
Closed account data: Following the closure of a bk664 account — whether at the player's request or by bk664 — personal data is retained for a minimum period (typically 5 years from closure) to satisfy anti-money-laundering record-keeping requirements and to resolve any post-closure disputes or regulatory enquiries.
KYC documents: Identity verification documents (National ID, passport, driving licence) are retained for the period required by applicable law, and are securely destroyed thereafter. bk664 does not retain KYC documents beyond the legally mandated retention window.
Communication records: Support chat transcripts and email correspondence are retained for up to 3 years from the date of the last interaction, to support complaint resolution and staff quality assurance.
Technical and usage logs: Server logs and session data used for fraud detection and security purposes are retained for up to 12 months, after which they are anonymised or deleted.
Marketing data: Where you have opted in to marketing communications, your marketing preference data is retained until you withdraw consent. Following withdrawal, your email address is added to a suppression list to prevent future communications — it is not deleted immediately, as retention of the suppression record prevents accidental re-subscription.

When personal data is no longer required and no legal obligation mandates its retention, bk664 securely destroys or anonymises it in accordance with our internal data lifecycle management procedures. Anonymised data (which cannot be used to identify any individual) may be retained indefinitely for aggregated statistical analysis.

Section 7

Your Privacy Rights

As a bk664 player, you hold a number of rights in relation to your personal data. bk664 is committed to respecting and facilitating these rights. To exercise any of the rights listed below, contact the bk664 privacy team at [email protected] (plain text — not a clickable link) with the subject line "Privacy Request — [Right Type]". bk664 will acknowledge your request within 3 business days and respond in full within 30 days.

Right of Access Request a copy of all personal data bk664 holds about you, along with information on how it is being used.

Right to Rectification Request correction of any inaccurate or incomplete personal data held in your bk664 account or records.

Right to Erasure Request deletion of your personal data where it is no longer necessary for the purpose it was collected, subject to legal retention obligations.

Right to Restriction Request that bk664 restricts processing of your data — for example, while the accuracy of a data point is being contested.

Right to Portability Request your personal data in a structured, commonly used, machine-readable format for transfer to another service provider.

Right to Object Object to processing based on legitimate interests or for direct marketing purposes. bk664 will cease that processing unless compelling grounds override your objection.

Right to Withdraw Consent Where processing is based on your consent (e.g., marketing emails), you may withdraw that consent at any time without affecting prior lawful processing.

Rights re: Automated Decisions Request human review of any decision made about you using automated processing where that decision has a significant effect on your account status.

bk664 will not charge a fee for handling privacy requests in standard circumstances. Where a request is manifestly unfounded or excessive (for example, repetitive requests within a short timeframe), bk664 may charge a reasonable administrative fee or decline to act, and will explain the reason for doing so in writing.

Section 8

Data Security Measures

bk664 employs a layered security architecture to protect your personal data against unauthorised access, accidental loss, alteration, and unlawful disclosure. The key technical and organisational measures in place include:

256-bit SSL/TLS encryption: All data transmitted between your browser or app and the bk664 platform is encrypted in transit using industry-standard TLS 1.2 or higher. This prevents interception of your credentials, payment data, and personal information during transmission.
Password hashing: Account passwords are never stored in plain text. bk664 uses a strong, salted hashing algorithm so that even in the unlikely event of a database breach, your password cannot be recovered from stored data.
Access controls: Access to personal data within bk664's internal systems is strictly limited to staff members who require it to perform their job functions. Role-based access controls and audit logging are applied to all systems holding sensitive player data.
Two-factor authentication (2FA): bk664 supports and encourages the use of 2FA on all player accounts. Enabling 2FA significantly reduces the risk of unauthorised account access even if your password is compromised.
Intrusion detection and monitoring: bk664's infrastructure is monitored continuously for anomalous activity, unauthorised access attempts, and indicators of compromise. Alerts are reviewed by our security team around the clock on Bangladesh Standard Time (BST, UTC+6).
Regular security assessments: bk664 conducts periodic security reviews and vulnerability assessments of its platform to identify and remediate weaknesses before they can be exploited.
Data minimisation at rest: Only the minimum data necessary for each operational function is stored in live production systems. Older records are archived in encrypted, access-controlled storage tiers with separate authentication requirements.

Your responsibilities. While bk664 implements robust technical safeguards, the security of your account also depends on the steps you take. Use a strong, unique password for your bk664 account, enable 2FA, do not share your login credentials with anyone, and log out of your account when using shared or public devices. If you suspect that your account has been compromised, contact bk664 support immediately at [email protected] (plain text — not a clickable link).

Data breach response. In the event of a personal data breach that poses a risk to your rights and freedoms, bk664 will notify affected players without undue delay — and within 72 hours of becoming aware of the breach where feasible. Notifications will be sent to the registered email address on your account and will include a description of the nature of the breach, the categories of data involved, the likely consequences, and the measures bk664 has taken or proposes to take in response.

Section 9

Third-Party Services

The bk664 platform integrates with a number of third-party services to deliver a complete gaming and betting experience to players across Bangladesh. This section explains how each category of third-party service interacts with your personal data.

Game providers: bk664 partners with internationally recognised game studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. When you launch a game from one of these providers, a secure game session is established between your device and the provider's servers. The provider receives your anonymous player session ID and game activity data — they do not receive your name, contact details, or payment information.
Payment service providers: To process deposits and withdrawals, bk664 works with bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, City Bank, and BRAC Bank. These providers receive only the transaction data required to execute your payment. bk664 does not store your full mobile wallet PIN, bank card number, or internet banking credentials — these are entered directly on the provider's own secure interface.
KYC verification services: Identity verification is handled by accredited third-party KYC providers. These providers process your submitted documents under strict data handling agreements and are prohibited from using your identity data for any purpose other than the specific verification task requested by bk664.
Customer support tools: bk664's support team uses internal ticketing and communication tools to manage player enquiries. Any personal data included in your support messages is accessible only to authorised support staff and is retained in accordance with the retention periods set out in Section 6 of this Policy.
Analytics services: bk664 may use privacy-preserving analytics tools to monitor platform performance and aggregate player behaviour patterns. Where such tools are used, they are configured to anonymise IP addresses and avoid collection of personally identifiable information at the analytics layer.

Third-party links. The bk664 platform does not contain outbound links to third-party websites for commercial or advertising purposes. If you navigate away from bk664 to a payment provider's interface (for example, bKash or Nagad), you are subject to that provider's own privacy policy from the moment you leave the bk664 platform. bk664 is not responsible for the privacy practices of third-party sites or services.

All third-party service providers engaged by bk664 are required to sign data processing agreements that bind them to process personal data only as instructed by bk664, to implement appropriate security measures, and to assist bk664 in meeting its obligations under this Privacy Policy.

Section 10

Policy Updates & Contact

Right to amend. bk664 reserves the right to update or replace this Privacy Policy at any time to reflect changes in our data practices, platform features, or applicable legal requirements. Where changes are material — meaning they substantially affect how we use or protect your personal data — bk664 will provide at least 7 days' advance notice to registered players via their registered email address or via a prominent on-platform notification before the updated Policy takes effect.

Non-material changes. Minor amendments such as typographical corrections, structural reorganisation that does not alter the substance of any provision, or clarifications that do not change the meaning of existing text may be implemented without prior notice. The "Effective Date" shown at the top of this Policy will be updated to reflect the date of the most recent revision.

Continued use. Your continued use of the bk664 platform after an updated Privacy Policy has come into effect constitutes your acknowledgement of the changes. If you do not agree with the updated Policy, you should stop using the platform and contact bk664 to request account closure before the effective date of the revised Policy.

Version history. bk664 maintains an internal record of all previous versions of this Privacy Policy. Players who wish to review a prior version may submit a written request to the privacy team, and bk664 will provide the requested version within 10 business days.

Contact the privacy team. For any questions, concerns, data subject access requests, or formal complaints relating to this Privacy Policy or bk664's data practices, please contact us at:

Email: [email protected] (plain text — not a clickable link)
Subject line: "Privacy Request — [describe your enquiry]"
Response time: Acknowledgement within 3 business days; full response within 30 days
Support hours: 24/7 — Bangladesh Standard Time (BST, UTC+6)

This Privacy Policy was last reviewed and updated on 1 January 2026. This is Version 2.0 of the bk664 Privacy Policy. Players are encouraged to review this page periodically. If you have unresolved concerns about our data practices that we have not addressed to your satisfaction, you have the right to escalate the matter to the relevant data protection authority or competent dispute resolution body in your jurisdiction.
