399b Privacy Policy — Your Data, Protected

How 399b Protects Your Privacy

Six core commitments that define how we handle your personal data every single day.

256-bit SSL Encryption

Every piece of data transmitted between your device and the 399b platform is protected by 256-bit SSL encryption — the same standard used by major banks. Your login details, payment information, and personal data are encrypted at every point of transfer.

Secure Data Storage

Your personal data is stored on secure, access-controlled servers. Only authorised 399b personnel with a legitimate operational need can access player data, and all access is logged and audited. We do not store payment card details on our servers.

No Third-Party Data Sales

399b does not sell, rent, or share your personal information with advertisers or data brokers. The only time your data is shared with a third party is when it is strictly necessary to operate the platform — for example, with payment processors to handle your transactions.

You Control Your Data

399b players have the right to access, correct, and request deletion of their personal data at any time. You can update most of your account information directly from your account settings, or contact the support team for assistance with data requests.

Marketing Opt-Out

If you do not want to receive promotional emails or SMS messages from 399b, you can opt out at any time from your account settings or by contacting support. Opting out of marketing does not affect your ability to use the platform or receive important account notifications.

Regular Security Audits

399b's data security practices are reviewed and audited on a regular basis. We update our security measures in response to new threats and industry best practices. Our security team monitors the platform continuously for any signs of unauthorised access or data breach.

1 Introduction

This Privacy Policy explains how 399b ("399b", "we", "us", "the platform") collects, uses, stores, and protects the personal information of players who register and use the 399b online gaming platform at 399b.net. This policy applies to all players accessing 399b from Bangladesh and any other jurisdiction where the platform is available.

By creating a 399b account or using any part of the platform, you confirm that you have read and understood this Privacy Policy and consent to the collection and use of your personal data as described here. If you do not agree with this policy, you should not use the 399b platform.

399b is committed to handling your personal data responsibly. We collect only what we need, use it only for legitimate purposes, and protect it with industry-standard security measures. This policy is written in plain language because we believe every 399b player deserves to understand exactly how their information is handled — not just the ones who read legal documents for fun.

This Privacy Policy should be read alongside the 399b Terms and Conditions. Together, these documents govern your relationship with the 399b platform.

2 Data We Collect

399b collects personal data in several ways — directly from you when you register or use the platform, automatically through your use of the site, and occasionally from third parties such as payment processors. Below is a clear breakdown of the categories of data we collect and why.

Data Category Examples How Collected
Identity Data Full name, date of birth, national ID number Registration form, KYC verification
Contact Data Mobile number, email address Registration form, account settings
Financial Data bKash / Nagad / Rocket account number, transaction history Deposit and withdrawal requests
Technical Data IP address, device type, browser, operating system Automatically on site visit
Usage Data Games played, bet amounts, session duration, login times Automatically during platform use
Communications Data Support chat transcripts, email correspondence When you contact 399b support

399b does not collect sensitive personal data such as racial or ethnic origin, political opinions, religious beliefs, or health information unless specifically required by law or for responsible gaming purposes.

3 How We Use Your Data

Every piece of data 399b collects is used for a specific, legitimate purpose. We do not collect data speculatively or hold information we have no use for. Here is how your personal data is used on the 399b platform:

  • To create and manage your 399b account, including verifying your identity and age during registration.
  • To process deposits and withdrawals via bKash, Nagad, and Rocket, and to maintain accurate transaction records.
  • To detect and prevent fraud, money laundering, and other prohibited activities on the platform.
  • To provide customer support and respond to your queries, complaints, and account requests.
  • To send you important account notifications such as deposit confirmations, withdrawal updates, and security alerts.
  • To send promotional communications about 399b bonuses and offers — only if you have opted in to receive them.
  • To comply with legal and regulatory obligations applicable to the operation of an online gaming platform.
  • To analyse platform usage patterns and improve the 399b user experience over time.
  • To enforce the 399b Terms and Conditions and protect the rights of all players on the platform.

399b uses your usage data and gaming history to support responsible gaming. If our systems detect patterns that suggest a player may be experiencing gambling-related harm, we may reach out proactively to offer support tools.

4 Legal Basis for Processing

399b processes your personal data on one or more of the following legal bases, depending on the specific purpose of the processing:

  • Contract performance: Processing your data is necessary to provide the 399b service you have signed up for — including account management, deposits, withdrawals, and game access.
  • Legal obligation: 399b is required by law to collect and retain certain data, including identity verification records and transaction histories, for anti-money laundering and fraud prevention purposes.
  • Legitimate interests: 399b has a legitimate interest in processing data to detect fraud, improve platform security, and analyse usage patterns to enhance the player experience.
  • Consent: Where 399b relies on your consent — for example, to send you marketing communications — you have the right to withdraw that consent at any time without affecting the lawfulness of processing carried out before withdrawal.

5 Data Sharing

399b does not sell, rent, or trade your personal data to any third party. Your information is shared only in the limited circumstances described below, and only to the extent necessary for the stated purpose.

  • Payment processors: bKash, Nagad, and Rocket receive the minimum data necessary to process your deposits and withdrawals. These providers operate under their own privacy policies and are bound by applicable data protection obligations.
  • Identity verification providers: When KYC verification is required, your identity documents may be processed by a third-party verification service operating under strict confidentiality agreements.
  • Legal authorities: 399b may be required to disclose player data to law enforcement or regulatory authorities in response to a lawful request, court order, or legal obligation. We will notify affected players where legally permitted to do so.
  • Platform service providers: Certain technical functions of the 399b platform — such as hosting, analytics, and customer support tools — are provided by third-party vendors who process data on our behalf under strict data processing agreements.

All third parties who process data on behalf of 399b are contractually required to handle that data securely and use it only for the specific purpose for which it was shared.

6 Cookies & Tracking Technologies

399b uses cookies and similar tracking technologies to operate the platform, remember your preferences, and analyse how players use the site. A cookie is a small text file stored on your device when you visit a website. Cookies do not contain your personal information directly, but they can be used to identify your browser or device.

The types of cookies used on the 399b platform include:

  • Essential cookies: Required for the platform to function. These include session cookies that keep you logged in and security cookies that protect against cross-site request forgery. These cannot be disabled.
  • Functional cookies: Remember your preferences such as language settings and display options to personalise your experience on 399b.
  • Analytics cookies: Help 399b understand how players navigate the platform, which pages are most visited, and where technical issues occur. This data is aggregated and anonymised.
  • Marketing cookies: Used only if you have consented to receive personalised promotions. These track which 399b offers you have viewed or interacted with.

You can manage your cookie preferences through your browser settings. Note that disabling essential cookies may affect the functionality of the 399b platform. For most players, the default cookie settings provide the best experience.

7 Data Retention

399b retains your personal data for as long as your account is active and for a period after account closure as required by law and legitimate business needs. The specific retention periods for different categories of data are as follows:

  • Account and identity data: Retained for the duration of your account and for a minimum of five years after account closure, in line with anti-money laundering regulations.
  • Transaction records: Retained for a minimum of five years from the date of each transaction to comply with financial record-keeping requirements.
  • Support communications: Retained for two years from the date of the last communication, unless a longer period is required for an ongoing dispute or legal matter.
  • Technical and usage data: Retained for up to 24 months in identifiable form, after which it is anonymised or deleted.
  • Marketing consent records: Retained for as long as you remain opted in, plus a reasonable period after opt-out to demonstrate compliance.

When data is no longer required, 399b deletes or anonymises it securely. Players can request early deletion of certain data categories — see Section 8 for details of your rights.

8 Your Privacy Rights

As a 399b player, you have a number of rights in relation to your personal data. 399b is committed to honouring these rights promptly and without unnecessary barriers. Here is a summary of what you are entitled to:

Right of Access

Request a copy of all personal data 399b holds about you. We will provide this within 30 days of your request.

Right to Rectification

Ask us to correct any inaccurate or incomplete personal data held in your 399b account.

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

Ask 399b to restrict processing of your data in certain circumstances, such as while a dispute about accuracy is being resolved.

Right to Portability

Receive your personal data in a structured, machine-readable format so you can transfer it to another service if you choose.

Object to processing of your data for direct marketing purposes at any time. We will stop immediately upon receiving your request.

To exercise any of these rights, contact the 399b support team via live chat or email at [email protected]. We will respond within 30 days. In some cases, we may need to verify your identity before processing your request.

9 Children's Privacy

The 399b platform is strictly for adults aged 18 and over. 399b does not knowingly collect personal data from anyone under the age of 18. If you are a parent or guardian and believe that a minor has registered on 399b or provided personal data to the platform, please contact us immediately at [email protected].

Upon receiving a verified report of underage registration, 399b will close the account immediately, delete all associated personal data, and return any deposited funds to the original payment method after deducting any winnings generated during the period of underage use, in accordance with the 399b Terms and Conditions.

399b uses age verification checks during registration and may request additional proof of age at any time. Protecting minors from online gambling is a responsibility we take seriously.

10 Security Measures

399b implements a comprehensive set of technical and organisational security measures to protect your personal data against unauthorised access, loss, alteration, or disclosure. These measures include:

  • 256-bit SSL/TLS encryption for all data transmitted between your device and the 399b platform.
  • Encrypted storage of sensitive data including passwords (stored as salted hashes, never in plain text) and financial account references.
  • Role-based access controls ensuring that only authorised personnel can access player data, and only to the extent required for their role.
  • Continuous monitoring of platform infrastructure for signs of intrusion, unusual access patterns, or data breach attempts.
  • Regular penetration testing and security audits conducted by independent security professionals.
  • Two-factor authentication (2FA) available for all player accounts to add an extra layer of login security.

Despite these measures, no online platform can guarantee absolute security. In the unlikely event of a data breach that affects your personal information, 399b will notify affected players promptly and take immediate steps to contain and remediate the breach.

You also play a role in keeping your 399b account secure. Use a strong, unique password, enable 2FA, and never share your login credentials with anyone. If you suspect your account has been compromised, contact 399b support immediately via live chat.

399b may update this Privacy Policy from time to time to reflect changes in our data practices, legal requirements, or platform features. When we make changes, the updated policy will be published on this page with a revised "Last Updated" date at the top.

For significant changes that materially affect how we use your personal data, 399b will notify you via email or an in-platform notification before the changes take effect. Your continued use of the 399b platform after any update constitutes acceptance of the revised Privacy Policy.

We recommend bookmarking this page and reviewing it periodically. The "Last Updated" date at the top always reflects when the most recent change was made.
