bk4 Privacy Policy — How We Handle Your Personal Data

bk4 ("we", "us", "the Platform") is committed to protecting the privacy and personal data of every player who uses our online gaming services. This Privacy Policy describes the categories of personal data we collect about you when you register, deposit, play, or otherwise interact with bk4, the purposes for which we process that data, the legal basis for doing so, the third parties with whom we may share it, and the rights you have in relation to your personal data.

This Privacy Policy applies to all users of bk4, including players accessing the platform from Dhaka, Chittagong, Sylhet, Rajshahi, Khulna, Barisal, Rangpur, Mymensingh, and all other locations within Bangladesh. By creating an account or using any bk4 service, you acknowledge that you have read and understood this Privacy Policy and consent to the collection and processing of your personal data as described herein.

bk4 uses the personal data we collect for the following purposes:

• Account management: to create, maintain, and administer your bk4 player account, including processing your registration, verifying your identity, and managing your account settings.
• Payment processing: to process deposits and withdrawals via bKash, Nagad, Rocket, Upay, and bank transfer; to verify that funds originate from payment methods registered in your name; and to maintain a complete transaction history for your account.
• Legal compliance: to comply with age verification requirements, anti-money laundering (AML) obligations, Know Your Customer (KYC) regulations, and any other applicable legal requirements.
• Fraud prevention and security: to detect, investigate, and prevent fraudulent transactions, account takeover attempts, bonus abuse, and other prohibited conduct that would harm bk4 or its player community.
• Responsible gaming: to monitor account activity for indicators of problem gambling and to enforce responsible gaming tools such as deposit limits and self-exclusion requests where activated by you or mandated by our responsible gaming policy.
• Service communications: to send you important account notifications, security alerts, transaction confirmations, and updates to these policies. We do not send unsolicited promotional emails without your consent.

bk4 does not use your personal data for automated decision-making that produces legal effects or similarly significant effects without human review. Where automated systems flag an account for review (for example, fraud detection), a human member of the bk4 compliance team reviews the flag before any account action is taken.

bk4 processes payment data in connection with your deposits and withdrawals. We do not store your full bKash PIN, Nagad PIN, bank card number, or internet banking credentials on our servers. Payment authentication is handled directly by the payment provider's secure gateway. bk4 retains only the transaction reference number, amount, timestamp, and payment method type required to maintain your account transaction history and to process any queries or disputes.

All withdrawals from bk4 are returned to the same payment method used for the original deposit, and to an account confirmed as belonging to the registered player. This policy protects players against unauthorised fund diversions and ensures that bk4 cannot be used as a vehicle for financial crime.

As a bk4 player, you have the following rights in relation to your personal data. To exercise any of these rights, contact bk4 support at [email protected] with the subject line "Data Rights Request" and your registered mobile number:

• Right of access: you may request a copy of all personal data bk4 holds about you. We will provide this within 30 days of a verified request.
• Right to rectification: if any personal data we hold about you is inaccurate or incomplete, you may request that we correct it. Identity data corrections will require supporting documentation.
• Right to erasure: you may request deletion of your personal data. We will fulfil erasure requests subject to our legal obligations to retain certain data (for example, transaction records required for AML compliance cannot be deleted before the mandatory retention period expires).
• Right to restriction: you may request that we restrict the processing of your personal data while a rectification or erasure request is under review, or where you contest the accuracy of data we hold.
• Right to withdraw consent: where processing is based on your consent (for example, promotional communications), you may withdraw that consent at any time by updating your account notification preferences or contacting support. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

bk4 will respond to all data rights requests within 30 days. Where a request is complex or we receive a high volume of requests, we may extend this period by a further 30 days and will notify you accordingly. There is no charge for exercising your data rights.

bk4 reserves the right to update this Privacy Policy at any time to reflect changes in our data practices, applicable law, or platform functionality. When material changes are made, we will notify registered players via on-platform notification or by SMS to your registered mobile number at least 7 days before the revised policy takes effect. The revised policy will be published on this page with an updated "Last updated" date.

Your continued use of bk4 after the effective date of any revised Privacy Policy constitutes your acceptance of the revised policy. If you do not agree with the changes, you must stop using the platform and may request account closure by contacting bk4 support.
