Privacy Policy — How btk1 Protects Your Data

About This Privacy Policy

This Privacy Policy ("Policy") sets out how btk1 ("the Platform", "we", "us", "our") collects, uses, stores, shares, and protects the personal information of individuals ("you", "your", "the Player") who access or use the btk1 website and associated services, including sports betting, live casino, slot games, promotional activities, and all account and payment functionality.

This Policy applies to all btk1 users, including registered account holders, visitors browsing the platform without an account, and former account holders whose data we may still be required to retain for legal or regulatory purposes. It covers all personal data collected through the btk1 website, our live chat support system, WhatsApp communications, and any other channel through which you interact with btk1.

btk1 takes its data protection responsibilities seriously. We are committed to handling your personal information with integrity, transparency, and in accordance with applicable data protection principles. Where we process your data, we do so only for defined, legitimate purposes and with appropriate safeguards in place.

This Policy was last reviewed and updated in January 2026. The current version supersedes all prior versions of the btk1 Privacy Policy.

Personal Data We Collect

btk1 collects personal data from you in several ways — directly when you provide it, automatically through your use of the platform, and from trusted third-party sources where permitted. The categories of personal data we collect are described below.

We do not collect sensitive personal data such as racial or ethnic origin, religious beliefs, biometric data (except where a photograph is submitted for age/identity verification), or health information, unless directly relevant to a responsible gaming request.

How We Use Your Personal Data

btk1 uses the personal data it collects for the following specific, legitimate purposes:

• Account management: To create, maintain, verify, and administer your btk1 player account, including processing your registration details and authenticating your identity at login.
• Service delivery: To provide access to betting markets, casino games, live dealer tables, slot games, promotional offers, and all other btk1 platform features.
• Payment processing: To process deposits via bKash, Nagad, Rocket, Upay, Visa, and Mastercard, and to execute withdrawal requests to your verified payment method.
• Identity and age verification: To verify that you are who you say you are, that you are at least 21 years of age, and that your payment method belongs to you. We may use third-party verification services for this purpose.
• Fraud prevention and security: To detect, investigate, and prevent fraudulent transactions, money laundering, collusion, bonus abuse, and other forms of prohibited conduct as defined in our Terms and Conditions.
• Customer support: To respond to your enquiries, resolve disputes, process complaints, and provide assistance via live chat, WhatsApp, and email.
• Responsible gaming: To monitor gaming patterns for signs of problem gambling, to enforce deposit and session limits you have set, and to process self-exclusion requests promptly and effectively.
• Legal compliance: To comply with applicable laws and regulations, including anti-money laundering obligations, and to respond to lawful requests from competent authorities.
• Platform improvement: To analyse usage data in aggregate form to understand how players interact with the platform and to inform product development, technical improvements, and content strategy.
• Marketing communications: Where you have given explicit consent, to send you information about btk1 promotions, bonuses, and new game releases. You may withdraw consent for marketing communications at any time by contacting support.

btk1 does not use your personal data for automated decision-making that produces significant legal effects, except where such processing is necessary to assess fraud risk or to enforce responsible gaming obligations, in which case you retain the right to request human review of any automated decision.

Legal Basis for Processing

btk1 processes your personal data on one or more of the following legal bases, depending on the specific processing activity:

• Contractual necessity: Processing your identity, contact, and financial data is necessary to enter into and perform the contract between you and btk1 — specifically, to provide you with a registered player account and the associated gaming and payment services.
• Legal obligation: Certain processing activities — including identity verification, transaction record-keeping, and cooperation with law enforcement — are required by applicable laws and regulations. btk1 must carry out this processing regardless of your preferences.
• Legitimate interests: btk1 processes technical and usage data on the basis of its legitimate interests in operating a secure, well-functioning platform, preventing fraud and abuse, and improving its services. We carry out a balancing exercise to ensure these interests do not override your privacy rights.
• Consent: Where processing is based on your consent — for example, receiving marketing communications — you may withdraw that consent at any time by contacting btk1 support. Withdrawal of consent does not affect the lawfulness of processing carried out before the withdrawal.

Cookies & Tracking Technologies

btk1 uses cookies and similar tracking technologies on its website. A cookie is a small text file placed on your device when you visit a website. We use the following categories of cookies:

• Strictly necessary cookies: These are essential for the platform to function. They maintain your login session, remember your language preference, and enable core security features. These cookies cannot be disabled without impairing platform functionality.
• Performance and analytics cookies: These collect anonymised information about how visitors use the btk1 platform — for example, which pages are visited most frequently and whether error messages are encountered. This data helps us improve the platform.
• Functional cookies: These remember choices you have made, such as your preferred deposit method or game display settings, to provide a more personalised experience during future visits.
• Session cookies: These are temporary cookies that are deleted automatically when you close your browser. They are used to maintain your active session while you navigate the platform.

You can manage cookie preferences through your browser settings. Please be aware that disabling certain cookies may affect the availability of platform features. btk1 does not use third-party advertising cookies or permit third-party ad networks to place cookies on the btk1 platform.

Sharing Your Data with Third Parties

btk1 does not sell, rent, or commercially trade your personal data. We share personal data with third parties only in the following defined circumstances:

• Payment processors: Your financial data is shared with payment processing partners — including bKash, Nagad, Rocket (Dutch-Bangla Bank), Upay, Visa, and Mastercard — solely to execute the deposit and withdrawal transactions you initiate. These providers operate under their own privacy policies and applicable financial regulations.
• Identity verification providers: Where required, we may share identity and document data with third-party Know Your Customer (KYC) verification services to confirm your identity and age. These providers are contractually bound to process your data only for verification purposes.
• Game studios and content providers: Certain usage data may be shared with certified game studios — including Evolution Gaming, Pragmatic Play, Ezugi, NetEnt, Microgaming, and Spribe — to resolve disputes about game outcomes or to comply with their fair-play audit obligations. No unnecessary personal data is shared with game providers.
• IT and platform service providers: We use third-party technology vendors for hosting, data storage, security monitoring, and platform infrastructure. These vendors act as data processors on our behalf and are permitted to use your data only as we direct, under formal data processing agreements.
• Legal and regulatory authorities: btk1 may disclose personal data to law enforcement agencies, financial intelligence units, or other competent authorities where required to do so by law, or where disclosure is necessary to protect the legal rights, safety, or property of btk1 or other users.

In all cases where personal data is shared with third parties, btk1 takes reasonable steps to ensure that the recipient applies equivalent standards of data protection and processes the data only for the specified purpose.

Data Security

btk1 implements a range of technical and organisational measures to protect your personal data against unauthorised access, disclosure, alteration, and destruction. Our security framework includes the following measures:

• SSL/TLS encryption: All data transmitted between your device and the btk1 platform is encrypted using industry-standard SSL/TLS protocols. You can verify this by the padlock symbol in your browser's address bar.
• Password hashing: Account passwords are stored in hashed form using a strong cryptographic algorithm. btk1 does not store passwords in plaintext and our staff cannot read your password.
• OTP authentication: Sensitive account actions, including login, withdrawal requests, and password resets, are protected by one-time password (OTP) verification sent to your registered mobile number. Never share your OTP with anyone.
• Access controls: Access to personal data within btk1's internal systems is restricted to personnel who require it to perform their role. Access is governed by role-based permissions and is subject to regular audit.
• Monitoring and intrusion detection: btk1 operates continuous security monitoring to detect suspicious activity, unauthorised access attempts, and potential data breaches in real time.
• Data breach response: In the event of a personal data breach that poses a risk to your rights and freedoms, btk1 will notify affected individuals without undue delay and take all reasonable steps to contain and remediate the breach.

While btk1 employs robust security measures, no online platform can guarantee absolute security. You remain responsible for maintaining the confidentiality of your own login credentials and for logging out of your account after each session, particularly on shared or public devices.

Data Retention

btk1 retains personal data only for as long as necessary to fulfil the purpose for which it was collected, or as required by applicable legal or regulatory obligations. The following general retention periods apply:

• Account data: Retained for the duration of your active account, plus a minimum of five years following permanent account closure. This retention period is required for anti-money laundering compliance and financial record-keeping obligations.
• Transaction records: Deposit and withdrawal records, including associated payment method data and transaction confirmations, are retained for a minimum of five years from the date of the transaction.
• Identity verification documents: Copies of identification documents submitted during the KYC process are retained for the duration of the account relationship plus five years, in line with applicable legal requirements.
• Customer support records: Live chat transcripts, WhatsApp message records, and support ticket logs are retained for up to two years from the date of the interaction, or longer if the matter is subject to ongoing dispute or legal proceedings.
• Technical and usage data: Log files and platform usage data are retained for up to 12 months in identifiable form, after which they may be anonymised and retained indefinitely for aggregate analytics purposes.
• Marketing consent records: Records of your marketing consent (or withdrawal of consent) are retained for five years from the date of the consent action, to demonstrate compliance with applicable requirements.

On expiry of the applicable retention period, personal data is securely deleted or irreversibly anonymised. Anonymised data that can no longer be used to identify you is not subject to this Policy and may be retained and used for statistical and platform improvement purposes indefinitely.

Your Privacy Rights

Subject to applicable law, you hold the following rights in respect of the personal data btk1 holds about you. To exercise any of these rights, please contact our support team via live chat or WhatsApp. We will respond to all verified requests within a reasonable timeframe.

Children's Privacy

btk1 is strictly an adults-only platform. Our services are intended for players who are at least 21 years of age. btk1 does not knowingly collect personal data from individuals under the age of 21.

If we become aware that personal data has been collected from a person under the age of 21, we will take immediate steps to delete that data and close the associated account. If you believe that a minor may have registered on the btk1 platform, please contact our support team immediately so we can investigate and act without delay.

Parents and guardians are encouraged to use parental control tools available on their devices and broadband connections to restrict access to online gambling platforms by minors. btk1 supports initiatives that promote responsible online environments for young people.

International Data Transfers

btk1 primarily serves players based in Bangladesh, and where possible, personal data is processed within the region. However, some of our third-party service providers — including cloud hosting providers, identity verification services, and game studio partners — may be located in or process data through servers based in other countries.

Where personal data is transferred outside of Bangladesh, btk1 takes reasonable steps to ensure that the recipient applies standards of data protection that are materially equivalent to those applied by btk1 itself. This may include the use of contractual data processing agreements, security certifications, or other appropriate safeguards.

By using the btk1 platform and providing your personal data, you acknowledge that your data may be transferred to and processed in countries outside Bangladesh as described in this section. btk1 will always ensure that such transfers are conducted lawfully and with appropriate protections in place.

Changes to This Privacy Policy

btk1 reserves the right to update or revise this Privacy Policy at any time to reflect changes in our data practices, applicable law, or platform features. When material changes are made, we will publish the updated Policy on this page with a revised effective date and, where appropriate, notify registered players via in-platform notification or a message to their registered mobile number or email address.

We encourage you to review this Policy periodically to stay informed about how btk1 protects your personal data. The date at the top of this page always reflects the most recent revision. Your continued use of the btk1 platform following the publication of a revised Policy constitutes your acknowledgement of the updated terms.
