1. Introduction
399bt ("we", "us", "our") operates https://399bt.bio and is responsible for the personal data of all registered players as data controller. This Privacy Policy ("Policy") describes how 399bt collects, processes, stores, shares, and protects personal data in connection with your use of the 399bt Platform, including the website, mobile site, and all associated services.

Before reading the full policy, here is a plain-language summary of the five most important things 399bt commits to regarding your personal data.
SSL Encryption on Every Session
Every connection between your device and the 399bt Platform is encrypted with SSL. Your login credentials, personal details, and payment information are never transmitted in plain text.
No Sale of Personal Data
399bt does not sell, rent, or share your personal data with third parties for their own marketing purposes. Your data is used exclusively to operate the 399bt Platform and fulfill our legal obligations.
Payment Data Stays with Your Provider
399bt does not store your bKash, Nagad, Rocket, or Upay PIN codes or full account credentials. Payment transactions are processed directly through the respective mobile money providers' secure APIs.
Right to Access & Correct Your Data
You have the right to request a copy of the personal data 399bt holds about you, and to request correction of any inaccurate data, at any time by contacting [email protected].
Right to Delete Your Data
You may request deletion of your personal data by contacting [email protected]. Deletion requests will be processed subject to any legal retention obligations 399bt is required to fulfill (for example, transaction records required for anti-money-laundering compliance).
3. Information We Collect
399bt collects personal data only where it is necessary for the purposes described in this Policy. The categories of data we collect and the means by which we collect them are set out below.
Registration Data
When you register a 399bt account, we collect: your Bangladeshi mobile phone number (used as your account username), a password you choose, and your date of birth (to verify that you are aged 21 or above). We may also request your full legal name and a copy of a government-issued identity document during KYC verification.
Transaction Data
Every deposit and withdrawal processed through your 399bt account generates a transaction record containing: the transaction reference number, the payment method used (bKash, Nagad, Rocket, or Upay), the transaction amount in BDT, the date and time of the transaction, and the transaction status. 399bt does not store your mobile money PIN or full account number.
Activity & Gaming Data
399bt records your betting and gaming activity on the Platform, including bets placed, games played, bet amounts, outcomes, and session timestamps. This data is used to operate the Platform correctly, calculate winnings, resolve disputes, identify problem gambling patterns, and fulfill responsible gaming obligations.
Technical & Device Data
When you access the 399bt Platform, our servers automatically record certain technical information, including: your IP address, browser type and version, operating system, device type, screen resolution, pages visited on the Platform, session duration, and referring URL. This data is used for Platform security, fraud detection, and technical optimisation. It is not linked to your personal identity beyond what is necessary for security purposes.
4. How We Use Your Information
399bt uses the personal data it collects solely for the following purposes. We do not use your data for any purpose not listed here without first obtaining your explicit consent.
- To create and administer your 399bt account, including verifying your identity and age (21+) as required.
- To process deposits, withdrawals, and all financial transactions through your selected mobile money provider (bKash, Nagad, Rocket, or Upay).
- To operate the betting and gaming features of the Platform, including settling bets, tracking game history, calculating bonuses, and enforcing responsible gaming tools such as deposit limits and self-exclusion.
- To detect and prevent fraud, money laundering, underage gambling, multiple account operation, and other prohibited conduct as defined in our Terms and Conditions.
- To respond to your support inquiries, complaints, and dispute submissions via [email protected], and to provide ongoing customer service in Bengali.
- To send you transactional communications (deposit confirmations, withdrawal notifications, account security alerts) and, where you have opted in, promotional communications about bonuses and offers. You may opt out of promotional communications at any time by contacting [email protected].
5. Legal Basis for Processing
399bt processes personal data only where a lawful basis for that processing exists. The three primary legal bases under which 399bt processes personal data are as follows.
Contractual Necessity
The majority of the data processing 399bt carries out is necessary to perform the contract between 399bt and you as a registered player — specifically, to create and maintain your account, process your transactions, settle your bets, and provide the Platform services you have signed up for.
Legal Obligation
Certain processing activities are required to comply with applicable legal obligations, including KYC identity verification, anti-money-laundering checks, age verification, and transaction record-keeping requirements. These obligations exist independently of the contract between 399bt and any individual player.
Legitimate Interests
Some processing activities are carried out based on 399bt's legitimate interests as a business, including Platform security monitoring, fraud detection, technical optimisation, and the maintenance of accurate betting records for dispute resolution purposes. Where processing is based on legitimate interests, 399bt has assessed that those interests are not overridden by your rights and freedoms as a data subject.
6. Sharing Your Information
399bt does not sell, rent, or trade personal data. We share personal data only in the limited circumstances described below, and only to the extent necessary for the stated purpose.
Mobile Money Payment Processors
To process deposits and withdrawals, 399bt must pass transaction data (mobile number, amount, transaction reference) to your chosen mobile money provider — bKash, Nagad, Rocket, or Upay. This data sharing is necessary to execute your payment and is governed by the privacy policy of the respective mobile money provider.
Game Content Providers
Casino game content on 399bt is provided by licensed third-party studios including Pragmatic Play, Evolution Gaming, Ezugi, NetEnt, and Microgaming. These providers may receive session data necessary to operate individual game rounds (e.g. stake amounts, game outcomes) but do not receive your personal identity information such as your name, mobile number, or payment details.
Legal & Regulatory Disclosure
399bt may be required to disclose personal data to law enforcement agencies, regulatory authorities, or courts where required by applicable law, including in connection with anti-money-laundering investigations, fraud investigations, or court orders. 399bt will disclose only the minimum data required to comply with such a request, and will notify the affected player of the disclosure where legally permitted to do so.
7. Payment Data & Mobile Money
All financial transactions on 399bt are processed in Bangladeshi Taka (BDT) through the mobile money providers you select — bKash, Nagad, Rocket, or Upay. 399bt does not store full mobile money account numbers or PIN codes. When you initiate a deposit or withdrawal, the minimum transaction information required (mobile number registered to your 399bt account, transaction amount, and a unique transaction reference) is passed to the relevant mobile money provider's API to authorise and execute the transaction.
Transaction records — including the date, amount, payment method, and outcome of each transaction — are retained by 399bt for a minimum of five (5) years from the date of the transaction to comply with applicable financial record-keeping requirements. These records may be accessed by 399bt's compliance team and, where legally required, by regulatory or law enforcement authorities.
8. Cookies & Tracking Technologies
The 399bt Platform uses cookies and similar tracking technologies to operate core Platform functions, maintain your login session, and analyse Platform usage. The following types of cookies are used on 399bt.
- Essential cookies: required for the Platform to function correctly. These include session cookies that keep you logged in and security cookies that protect your account. These cookies cannot be disabled without breaking core Platform functionality.
- Performance cookies: used to collect anonymised data about how visitors use the Platform, such as which pages are visited most frequently and how long sessions last. This data helps 399bt improve the Platform's speed, stability, and usability.
- Functionality cookies: used to remember your preferences within the Platform, such as your selected language version. These cookies improve your experience but are not strictly essential to Platform operation.
Most mobile browsers allow you to manage cookie preferences through the browser's settings menu. Disabling essential cookies may prevent some or all Platform features from working correctly. 399bt does not use third-party advertising cookies or cross-site tracking technologies.
9. Data Retention
399bt retains personal data only for as long as is necessary for the purposes for which it was collected or as required by applicable law. The following retention periods apply: account data and KYC documents are retained for the duration of your account plus a minimum of five (5) years after account closure; transaction records are retained for a minimum of five (5) years from the date of each transaction; gaming activity logs are retained for a minimum of three (3) years; technical and device data is retained for a maximum of twelve (12) months.
When the applicable retention period expires, 399bt will securely delete or anonymise the relevant personal data so that it can no longer be linked to any individual. Where anonymisation is not possible, 399bt will ensure secure deletion using industry-standard data destruction methods.
10. Your Rights
As a registered 399bt player, you hold the following rights in relation to the personal data we hold about you. To exercise any of these rights, contact [email protected]. 399bt will respond to all rights requests within 30 days of receipt.
Right of Access
You have the right to request a copy of all personal data 399bt holds about you. We will provide this data in a commonly used electronic format within 30 days of your request.
Right to Rectification
You have the right to request correction of any inaccurate or incomplete personal data 399bt holds about you. If you believe any information in your 399bt account is incorrect, contact [email protected] with details of the correction required.
Right to Erasure
You have the right to request that 399bt delete your personal data, subject to any legal retention obligations that prevent immediate deletion. Where full deletion is not immediately possible due to legal obligations, 399bt will suppress your data so that it is not actively used and will delete it as soon as the retention obligation expires.
Right to Restrict Processing
You have the right to request that 399bt restrict the processing of your personal data in certain circumstances — for example, where you contest the accuracy of the data or where you have objected to processing based on legitimate interests, while that objection is being assessed.
Right to Object
You have the right to object to 399bt processing your personal data where that processing is based on legitimate interests. If you object, 399bt will cease that processing unless it can demonstrate compelling legitimate grounds for the processing that override your interests, rights, and freedoms, or unless the processing is necessary for the establishment, exercise, or defence of legal claims.
11. Security Measures
399bt implements industry-standard technical and organisational security measures to protect the personal data it holds against unauthorised access, disclosure, alteration, and destruction. Key security measures include: SSL encryption on all Platform connections; encrypted storage of account passwords using one-way hashing; access controls limiting which 399bt personnel can access personal data and on what basis; regular security reviews of Platform infrastructure; and prompt response protocols for any suspected data security incidents.
In the event of a personal data breach that is likely to result in a risk to your rights and freedoms, 399bt will notify affected players without undue delay via the contact details registered to their 399bt account, and will take all reasonable steps to mitigate the impact of the breach. You should also take steps to protect your own account by keeping your password confidential, not sharing your login credentials with anyone, and contacting [email protected] immediately if you suspect your account has been compromised.
12. Minors & Age Restriction
The 399bt Platform is strictly for adults aged 21 years and above. 399bt does not knowingly collect personal data from any person under the age of 21. Registration on 399bt constitutes confirmation by the registrant that they are at least 21 years of age. If 399bt discovers that personal data has been collected from a person under the age of 21, that data will be deleted immediately and the account permanently closed.
13. Changes to This Policy
399bt reserves the right to amend this Privacy Policy at any time. Any amended version of this Policy will be published on this page with an updated effective date. Where an amendment materially changes how 399bt processes your personal data, 399bt will make reasonable efforts to notify registered players via their registered contact details before the amended Policy takes effect.
Continued use of the 399bt Platform after an amended Privacy Policy has been published constitutes your acceptance of the amended Policy. It is your responsibility to review this Policy periodically. If you do not accept the amended Policy, you may request account closure by contacting [email protected].
