bd4 Privacy Policy

1.1 Data You Provide Directly

When you register an account or interact with bd4 support, you provide us with personal data including:

• Full legal name as it appears on your national identity document;
• Date of birth (used for mandatory 21+ age verification);
• Registered mobile number (used for OTP authentication and payment);
• Mobile wallet account details (bKash, Nagad, Rocket, or Upay number);
• Residential address in Bangladesh;
• A copy of your National ID (NID) or passport when requested for KYC verification;
• Any correspondence you send to our support team, including chat transcripts and emails.

1.2 Data Collected Automatically

When you use the bd4 platform, we automatically collect technical and behavioural data, including:

• IP address and approximate geographic location;
• Device type, operating system, and browser version;
• Pages visited, games played, bet amounts, session duration, and click patterns;
• Login timestamps and frequency of access;
• Cookie and local storage identifiers (see Section 5 on Cookies).

1.3 Data from Third Parties

bd4 may receive personal data about you from third-party sources in limited circumstances, including:

• Payment processors (bKash, Nagad, Rocket, Upay) for transaction confirmation and fraud screening;
• Identity verification service providers when enhanced KYC checks are required;
• Game providers (Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, Ezugi) in relation to game session data and RNG outcomes.

2.1 Account Management and Service Delivery

The primary use of your personal data is to operate and maintain your bd4 account, process deposits and withdrawals, deliver game and betting services, provide customer support, and communicate important account-related information such as security alerts and policy updates.

2.2 Identity Verification and Fraud Prevention

bd4 uses identity and financial data to verify that all players are aged 21 or above, to screen transactions for signs of fraud or money laundering, to detect and prevent multi-accounting, and to ensure that withdrawals are processed to accounts held in the player's own name. These activities are a legal obligation and a core part of our responsible gaming framework.

2.3 Responsible Gaming Monitoring

Behavioural data — including bet frequency, session duration, deposit patterns, and loss history — is analysed by bd4 to identify signs of problem gambling. Where our systems detect unusual patterns consistent with compulsive gambling behaviour, our responsible gaming team may proactively reach out to the player to offer support tools such as deposit limits, cool-off periods, or self-exclusion.

2.4 Platform Improvement and Analytics

Aggregated, anonymised technical and behavioural data is used to improve the performance, reliability, and user experience of the bd4 platform. This includes identifying popular game categories, optimising page load times for mobile users across Dhaka, Chittagong, Sylhet, and other regions of Bangladesh, and prioritising new feature development.

2.5 Promotional Communications

With your consent at registration, bd4 may use your contact details to send you promotional offers, bonus announcements, and seasonal campaign information relevant to your interests (for example, BPL cricket betting promotions or Eid special bonuses). You may withdraw this consent at any time by contacting [email protected] or by adjusting your account notification preferences.

3.1 Payment Service Providers

To process deposits and withdrawals, bd4 must share transaction data with your chosen payment provider (bKash, Nagad, Rocket, or Upay). This sharing is limited to the information required to execute the transaction and is governed by each provider's own privacy practices. bd4 does not store full payment credentials on its own servers.

3.2 Game Providers

When you launch a game supplied by a third-party studio such as Pragmatic Play, Evolution Gaming, or Spribe, a game session token and anonymised player identifier are passed to that provider's platform to initialise the game. Game providers do not receive your name, mobile number, or financial details. All game providers used by bd4 are required to maintain their own data security standards.

3.3 Legal and Regulatory Disclosure

bd4 may be required to disclose personal data to law enforcement authorities, financial intelligence units, or other regulatory bodies where we are legally compelled to do so, or where we believe in good faith that disclosure is necessary to prevent fraud, money laundering, or harm to individuals. We will notify affected users of such disclosures where legally permitted to do so.

3.4 What We Will Never Do

• Sell or rent your personal data to advertisers, data brokers, or marketing agencies;
• Share your data with unrelated third parties for their own commercial purposes;
• Transfer your data to jurisdictions with inadequate data protection standards without appropriate safeguards;
• Use your data in any way that contradicts the stated purposes in this policy.

4.1 What Are Cookies

Cookies are small text files stored on your device when you visit bd4.games. They allow the platform to recognise your device, remember your session preferences, and collect anonymised usage analytics. bd4 uses both session cookies (which expire when you close your browser) and persistent cookies (which remain on your device for a set period).

4.2 Types of Cookies Used

• Strictly Necessary Cookies: Required for the bd4 platform to function. These include session authentication tokens and security cookies. They cannot be disabled.
• Functional Cookies: Remember your preferences such as language settings and notification choices to provide a more personalised experience.
• Analytics Cookies: Collect anonymised data about how players use bd4 — which games are most popular, how long sessions last, which pages are visited most. This data is aggregated and cannot identify individual players.

4.3 Managing Cookies

You can control non-essential cookies through your browser settings. Please note that disabling functional or analytics cookies may affect your experience on bd4.games — for example, your session preferences may not be retained between visits. Strictly necessary cookies cannot be disabled as they are essential to platform security and login functionality.

6.1 Security Measures

bd4 employs a layered security architecture to protect your personal data from unauthorised access, disclosure, alteration, or destruction. Key measures include 256-bit SSL/TLS encryption for all data in transit, bcrypt hashing for stored passwords, tokenisation of payment identifiers, OTP-based login authentication, intrusion detection systems, and regular third-party security audits of our infrastructure.

6.2 Data Retention Periods

bd4 retains personal data for the following periods:

• Active account data: Retained for the duration of your account's active status;
• Transaction records: Retained for a minimum of 5 years following the transaction date, in accordance with financial record-keeping obligations;
• KYC documents: Retained for a minimum of 5 years following account closure;
• Support correspondence: Retained for 3 years following resolution of the relevant matter;
• Analytics data: Anonymised after 12 months and retained in aggregate form thereafter.

6.3 Data Breach Response

In the event of a personal data breach that poses a risk to your rights and freedoms, bd4 will notify affected players without undue delay — and in any case within 72 hours of becoming aware of the breach. Notification will be sent to your registered mobile number and will include the nature of the breach, the data affected, and the steps bd4 is taking to mitigate harm.

7.1 Changes to This Policy

bd4 reserves the right to update this Privacy Policy at any time. Any material changes will be communicated to registered players via the contact details on their account, and the updated policy will be posted on this page with a revised effective date. Continued use of bd4 following notification of a material change constitutes acceptance of the revised policy.

7.2 Contact and Complaints

For any questions, requests, or concerns regarding this Privacy Policy or the handling of your personal data, please contact the bd4 Data Protection team. All privacy-related enquiries are handled in English and will receive a written response within 30 days.
