Privacy Policy — 399btd

1. Information We Collect

399btd collects personal information from you in several ways during the course of your relationship with us as a registered player. The categories of information we collect are described below, together with the context in which each category is gathered.

1.1 Registration and Identity Information

When you create a 399btd account, we collect the information you provide during the registration process. This includes your full legal name, date of birth, email address, mobile phone number, and the username and password you choose for your account. If you are required to complete our Know Your Customer (KYC) verification process, we will also collect copies of identity documents such as your National ID Card (NID), passport, or driving licence, and proof-of-address documents such as utility bills or bank statements.

1.2 Financial and Transaction Information

To process deposits and withdrawals, we collect details about the payment methods you use. For mobile financial services such as bKash, Nagad, Rocket, and Upay, this includes your registered mobile number and transaction reference numbers. For bank transfers, this includes account holder name, bank name, branch, and account number. For card payments via Visa or Mastercard, we collect the card type, the last four digits of the card number, and the billing name. Full card numbers and CVV codes are never stored by 399btd — they are transmitted directly to our certified payment processor over encrypted channels.

We also maintain records of all deposits, withdrawals, bonus credits, wager amounts, and game outcomes associated with your account for accounting, dispute resolution, and regulatory compliance purposes.

1.3 Technical and Device Information

When you access the 399btd platform, our servers automatically collect certain technical information about your device and connection. This includes your IP address, browser type and version, operating system, device identifiers, screen resolution, referring URL, pages visited within the platform, session duration, and time-stamps of access events. This data is used for security monitoring, fraud detection, platform optimisation, and analytics purposes.

1.4 Communications and Support Records

If you contact our customer support team via email, live chat, or any other channel, we retain records of those communications, including the content of your messages and any attachments you provide. These records allow us to resolve disputes effectively, improve our service quality, and maintain an audit trail of player interactions.

1.5 Voluntary Information

From time to time, you may voluntarily provide additional information — for example, when participating in a survey, entering a promotion, or providing feedback. Any such information is collected with your consent and used only for the stated purpose of the activity in question.

3. Cookies and Tracking Technologies

The 399btd platform uses cookies and similar tracking technologies to operate effectively, enhance user experience, and gather analytical insights. This section explains what cookies we use, why we use them, and how you can manage your cookie preferences.

3.1 What Are Cookies

Cookies are small text files that are placed on your device when you visit a website. They are widely used across the internet to make websites function correctly, to remember your preferences between sessions, and to provide website operators with information about how their platforms are being used. Cookies do not contain executable code and cannot directly harm your device.

3.2 Types of Cookies We Use

• Strictly Necessary Cookies: These cookies are essential for the 399btd platform to function. They manage your login session, maintain your account authentication state, enable the cashier to process transactions, and ensure platform security features operate correctly. These cookies cannot be disabled without materially impairing your ability to use the platform.
• Functional Cookies: These cookies remember your preferences — such as your preferred language settings, display options, and last-visited game sections — so that you do not have to reset them every time you return to 399btd.
• Analytical Cookies: We use anonymised analytical cookies to understand how players navigate the 399btd platform, which game categories are most popular, and where users encounter difficulties. This data is used exclusively to improve the platform experience and is not linked to any individual player identity.
• Security and Fraud-Prevention Cookies: These cookies help us identify potentially fraudulent login attempts, detect unusual activity patterns consistent with bot usage, and protect the integrity of betting markets.

3.3 Managing Your Cookie Preferences

You can manage or disable non-essential cookies through your browser settings. Most modern browsers — including Chrome, Firefox, Safari, and Edge — provide options to view, delete, and block cookies on a per-site basis. Please note that disabling functional cookies may affect your experience on the 399btd platform, and disabling strictly necessary cookies will prevent you from logging in or completing financial transactions.

4. Data Sharing and Disclosure

399btd does not sell your personal data. We share your information only in the limited circumstances described below, and only to the extent necessary for the stated purpose.

4.1 Payment Service Providers

To process your deposits and withdrawals, we share relevant financial information with our authorised payment processing partners. These include the operators of bKash, Nagad, Rocket, and Upay integrations, card payment gateways, and Bangladeshi banking partners. Each payment service provider operates under its own privacy policy and is bound by contractual data protection obligations consistent with those described in this policy. Payment processors receive only the minimum data required to complete the transaction and are not permitted to use that data for any other purpose.

4.2 Identity Verification Partners

Where we use third-party KYC verification services to confirm your identity and age, we share the identity documents and personal information you submit with those partners. These partners are selected on the basis of their security standards and are contractually required to process your data solely for verification purposes and to delete it once verification is complete.

4.3 Legal and Regulatory Authorities

399btd may be required by applicable law, court order, or regulatory directive to disclose certain player information to relevant authorities. This may include law enforcement agencies, financial intelligence units, or other government bodies with jurisdiction over gambling, anti-money laundering, or data protection matters. We will comply with all lawful disclosure requests and will notify you where we are legally permitted to do so prior to disclosing your data.

4.4 Responsible Gaming Organisations

Where a player has voluntarily enrolled in a self-exclusion scheme or where we have identified a player as at risk of gambling-related harm, we may share limited account information with responsible gaming support organisations or national self-exclusion registries to give effect to any exclusion request and to protect the player's wellbeing.

4.5 Service Providers and Technology Partners

We engage third-party service providers to assist with platform operations, including game technology providers (such as Pragmatic Play, Evolution Gaming, Spribe, and Ezugi), cloud hosting providers, analytics platforms, and customer support software vendors. These providers access only the data necessary to perform their contracted services and are bound by data processing agreements that prohibit use of your data for independent purposes.

5. Data Retention and Storage

399btd retains your personal data for as long as necessary to fulfil the purposes for which it was collected, to comply with applicable legal and regulatory obligations, and to resolve any disputes that may arise. The following retention principles apply:

5.1 Active Account Data

While your 399btd account remains active, we retain all account registration data, transaction records, game history, and communication logs as necessary to operate your account and provide our services. You can request a copy of all data held about you at any time during this period.

5.2 Post-Closure Retention

Following the closure of your account — whether initiated by you or by 399btd — we retain your personal data for a minimum period of five (5) years from the date of closure. This retention period is driven primarily by anti-money laundering regulations and financial record-keeping requirements that oblige us to maintain transaction records and identity verification documents for a defined statutory period. After this retention period expires, your data will be securely deleted or anonymised.

5.3 Communication Records

Records of customer support interactions, complaints, and dispute correspondence are retained for a period of three (3) years from the date of the last communication in the relevant thread, or until any related dispute is fully resolved, whichever is the later date.

5.4 Analytical Data

Anonymised, aggregated analytical data — from which no individual player can be identified — may be retained indefinitely for the purpose of long-term platform performance analysis and product development. Such data is not considered personal data once fully anonymised.

6. Your Privacy Rights

As a 399btd player, you have the following rights in relation to the personal data we hold about you. To exercise any of these rights, please contact us at [email protected] with sufficient detail to identify your account and the specific right you wish to exercise. We will respond to all verified requests within a reasonable timeframe.

6.1 Right of Access

You have the right to request a copy of all personal data that 399btd holds about you. We will provide this information in a structured, commonly used format. There is no fee for a standard access request, though we reserve the right to charge a reasonable administrative fee for repetitive or manifestly unfounded requests.

6.2 Right to Rectification

If any personal data we hold about you is inaccurate or incomplete, you have the right to request that we correct it. For basic account details such as email address and phone number, you may be able to update these directly via your account settings. For identity documents and legally verified data, corrections must be requested through our support team and may require re-verification.

6.3 Right to Erasure

You may request that we delete your personal data where it is no longer necessary for the purposes for which it was collected, where you have withdrawn consent (and no other lawful basis applies), or where you believe the data has been unlawfully processed. Please note that this right is subject to our legal obligations to retain certain categories of data as described in Section 5 — we may not be able to fulfil an erasure request in full where a legal retention obligation applies.

6.4 Right to Restrict Processing

In certain circumstances — for example, where you have contested the accuracy of your data and we are in the process of verifying it — you have the right to request that we temporarily suspend the processing of your data (other than storing it) while the matter is resolved.

6.5 Right to Object to Marketing

You have the right to object to the use of your personal data for direct marketing purposes at any time. Upon receipt of such an objection, we will cease sending you marketing communications promptly and will update your communication preferences accordingly.

7. Data Security Measures

399btd takes the security of your personal data seriously and has implemented a comprehensive set of technical and organisational measures designed to protect your information against unauthorised access, accidental loss, destruction, or disclosure.

7.1 Encryption

All data transmitted between your browser or device and the 399btd platform is encrypted using Transport Layer Security (TLS) with a minimum of 256-bit encryption. This applies to all platform pages, including the account login interface, the cashier, game lobbies, and customer support chat. Our SSL certificate is maintained in active status at all times and is renewed before expiry.

7.2 Access Controls

Access to systems and databases containing personal player data is restricted to authorised 399btd employees and approved third-party processors who require access to perform their job functions. All internal access is logged, and access privileges are reviewed periodically. Employees with access to personal data receive regular training on data protection obligations and security best practices.

7.3 Fraud and Anomaly Detection

399btd operates automated fraud detection and anomaly monitoring systems that analyse login patterns, transaction behaviour, and platform activity in real time. Where suspicious activity is detected — such as login attempts from unrecognised devices or IP addresses, unusual withdrawal requests, or patterns consistent with account compromise — automated safeguards are triggered and our security team is alerted for manual review.

7.4 Incident Response

In the event of a data security incident that affects your personal information and poses a risk to your rights or interests, 399btd will notify you as promptly as reasonably practicable following discovery of the incident, subject to any overriding legal constraints. Notification will be sent to your registered email address and will include a description of the nature of the incident, the categories of data affected, the likely consequences, and the steps we are taking to address it.

8. Policy Updates and Contact

399btd reserves the right to update this Privacy Policy at any time to reflect changes in our data practices, legal obligations, or platform services. When we make material changes to this policy, we will publish the updated version on this page with a revised "Last Reviewed" date and, where the changes are significant, we will notify registered players via their registered email address.

We encourage you to review this Privacy Policy periodically to stay informed about how we protect your personal information. Your continued use of the 399btd platform following the publication of an updated Privacy Policy constitutes your acceptance of the revised terms. If you do not agree to an updated version of this policy, you should cease using the platform and contact us to arrange closure of your account.

If you have any questions, concerns, or complaints about this Privacy Policy or about the way 399btd handles your personal data, please do not hesitate to contact us. Our team is available to assist you and will respond to all privacy-related enquiries within a reasonable timeframe.

This Privacy Policy was last reviewed and updated in January 2026. It applies to all personal data collected by 399btd in connection with the operation of the 399btd online casino and sports betting platform serving players in Bangladesh.
