399de Privacy Policy

How 399de collects, uses, and safeguards your personal information on our Bangladesh betting platform.

Effective 2026
Last updated: January 2026

1. Introduction

399de operates Bangladesh's trusted online casino and sports betting platform at 399de.pro. We are committed to protecting the privacy of every player who registers, deposits, or plays on 399de. This Privacy Policy sets out what personal information we collect, why we collect it, how we use and protect it, and what rights you hold over your own data.

This Privacy Policy applies to all users of the 399de platform, including registered account holders and visitors browsing without an account. By accessing 399de or opening an account, you confirm that you have read and accept this Privacy Policy. If you do not accept it, please do not use the platform.

399de does not sell your personal data to third parties, advertisers, or data brokers. All personal information collected by 399de is used solely to operate your account, verify your identity, process payments, prevent fraud, and improve the 399de service for players in Bangladesh.

2. Our Privacy Commitments

Six core principles guide every data decision 399de makes.

🔐

SSL Encryption

All data between your device and 399de servers is protected by SSL. Your login and payment details are never transmitted in plain text.

🚫

No Data Selling

399de never sells, rents, or trades your personal information with any third party for commercial gain.

🎯

Purpose Limitation

We collect only what is needed to run your account and process transactions. No speculative or unnecessary data is gathered.

🗑️

Right to Erasure

Request deletion of your personal data at any time by emailing [email protected], subject to our legal retention obligations.

📋

Transparent Policy

This policy is written in plain language. We do not hide data practices in technical footnotes or confusing legal language.

🙋

Player Control

Access, correct, export, or delete your data any time by contacting 399de support. We respond to all requests within 30 days.

3. Information We Collect

399de collects personal information in three ways: information you provide directly when you register or use the platform, data generated automatically by your use, and information received from third-party payment and identity verification partners.

Information You Provide Directly

When you register for a 399de account or update your profile, you provide us with the following:

  • Your full name, date of birth, and Bangladesh residential address provided at registration or during KYC verification.
  • Your Bangladesh mobile phone number, used as your primary account identifier and for account security communications.
  • Identity documents submitted for KYC verification, such as your National Identity Card (NID), passport, or driving licence, including document images.
  • Payment method details including your bKash, Nagad, Rocket, or Upay mobile wallet number, or bank account details where bank transfer is used. Full card numbers are never stored by 399de.

Automatically Generated Data

When you access or use the 399de platform, our systems automatically collect the following technical and behavioural data:

  • Device information including device type, operating system version, browser type, and unique device identifiers, used to optimise the 399de interface for your device and to detect unusual access patterns.
  • IP address and approximate geolocation derived from your IP, used for fraud detection, jurisdictional eligibility checks, and security monitoring. GPS-level location tracking is not used.
  • Session data including login timestamps, pages visited, game sessions started, bets placed, and navigation flow, used to detect prohibited conduct, investigate disputes, and improve the platform.
  • Cookies and similar tracking technologies as described in Section 7 of this Privacy Policy.

Information from Third Parties

399de may receive supplementary information from payment partners (bKash, Nagad, Rocket, Upay, and bank transfer providers) and identity verification service providers. This information is used only to verify your identity, confirm payment method ownership, and meet anti-money laundering obligations. We do not purchase data about you from commercial data brokers.

4. How We Use Your Information

399de uses your personal information for the following purposes, each supported by a clear legal basis described in Section 5:

  • Account management: creating and maintaining your 399de player account, authenticating your login, and enabling access to games, deposits, withdrawals, and bonus features.
  • Payment processing: handling your deposits and withdrawals via bKash, Nagad, Rocket, Upay, and bank transfer; reconciling your balance; and maintaining transaction records as required by applicable financial regulations.
  • Identity verification (KYC): confirming that you meet eligibility requirements to use 399de, including age verification (21+), residency, and payment method ownership, in compliance with anti-money laundering regulations.
  • Fraud prevention and security: monitoring account activity for signs of prohibited conduct, identity fraud, payment fraud, money laundering, and unauthorised access.
  • Customer support: responding to your queries, complaints, and dispute resolution requests. Support communications may be retained for quality assurance and as evidence in dispute resolution.
  • Platform improvement: analysing aggregated, anonymised usage data to improve the 399de platform, fix bugs, optimise mobile performance for Bangladesh players, and develop new features.

399de does not use your personal data for automated profiling that produces legally significant effects on you, and we do not make fully automated decisions about your account without a human review step available on request.

5. Legal Basis for Processing

Every use of your personal data by 399de is supported by at least one of the following legal bases.

Contractual Necessity

Most processing by 399de is necessary to perform our contract with you — to operate your account, accept bets, process deposits and withdrawals, and provide the services in our Terms and Conditions. Without this processing, we cannot provide the 399de service.

Legal Obligation

Some processing is required by applicable law, including anti-money laundering legislation, financial record-keeping requirements, and fraud reporting obligations. Transaction records and KYC documents are retained for the periods required by applicable regulations, even after account closure.

Legitimate Interests

Certain activities — fraud detection, security monitoring, platform analytics, and responsible gaming monitoring — are conducted on the basis of 399de's legitimate interests in running a safe and fair platform. Where we rely on this basis, we have assessed that our interests do not override your fundamental privacy rights.

6. Sharing Your Information

399de does not share your personal data with third parties except in the following circumstances, each of which is necessary for operating the platform or required by law:

  • Payment service providers: 399de shares payment-relevant data (your name, mobile wallet number, or bank account number) with bKash, Nagad, Rocket, Upay, and bank transfer partners solely to process your deposits and withdrawals. These providers are contractually prohibited from using your data for their own independent purposes.
  • Identity verification providers: where identity cannot be confirmed from documents you submit directly, 399de may share identity data with a licensed KYC verification service. These providers are bound by strict data processing agreements and may not use your data for any other purpose.
  • Law enforcement and regulators: 399de will disclose personal data to law enforcement agencies or regulatory bodies where required by applicable law or a valid legal order. Affected players will be notified where legally permitted.
  • Business transfers: in the event of a merger, acquisition, or sale of 399de's business, your personal data may transfer to the acquiring entity as part of that transaction. Affected players will be notified and the acquiring entity must honour this Privacy Policy.

In every case where 399de shares your data with a third party, we require that party to maintain appropriate security measures and to use your data only for the purpose for which it was shared.

7. Cookies and Tracking Technologies

399de uses cookies and similar browser-based technologies to operate the platform, maintain your session state, and collect the usage analytics described in Section 3. We do not use third-party advertising cookies or cross-site tracking technologies that follow you across the web.

Essential Cookies

Essential cookies are strictly necessary to operate 399de. They maintain your login session, store your language preference, and enable the deposit flow. Essential cookies cannot be disabled without breaking core platform functionality. They are set automatically when you access 399de and do not require your consent. They expire at the end of your browser session or after a fixed period (typically 30 days for session tokens).

Analytics Cookies

399de uses first-party analytics cookies to collect aggregated, anonymised data on how players navigate the platform — for example, which game categories are most visited and where errors occur. This data is used exclusively to improve 399de and is not shared with any advertising or analytics third party. You may disable analytics cookies in your browser settings without affecting your ability to use 399de.

8. Data Retention

399de retains your personal data for as long as your account remains active and for any additional periods required by applicable law or needed to resolve disputes. Specific periods: active account data is kept for the lifetime of the account; transaction records and KYC documents are retained for a minimum of five years after the relevant transaction or account closure (whichever is later), as required by financial regulations; customer support communications are kept for two years from the date of the communication; anonymised analytics data has no fixed deletion schedule as it contains no personal identifiers.

When personal data is no longer required and is not subject to a legal retention requirement, 399de will securely delete or irreversibly anonymise it. Players who have closed their accounts may request confirmation of deletion by emailing [email protected].

9. Your Privacy Rights

You have the following rights over the personal data 399de holds about you. To exercise any right, contact us at [email protected] with your registered account details and a description of the right you wish to exercise. We will respond within 30 days.

  • Right of access: request a copy of all personal data 399de holds about you, along with an explanation of the purposes for which it is processed and who it has been shared with.
  • Right to rectification: if personal data 399de holds about you is inaccurate or incomplete, request that we correct or complete it. Changes to identity data may require fresh KYC verification.
  • Right to erasure: request deletion of your personal data where it is no longer necessary for the purpose collected, or where you withdraw consent (where consent was the legal basis). This right is subject to our legal retention obligations — we cannot delete transaction records or KYC documents before the mandated retention period expires.
  • Right to data portability: request a copy of your personal data in a structured, machine-readable format so that you may transfer it to another service provider.
  • Right to object: object to processing carried out on the basis of 399de's legitimate interests. We will cease that processing unless we can demonstrate compelling legitimate grounds that override your interests, rights, and freedoms.

399de will not discriminate against you — for example by restricting game access or reducing bonus offers — because you have exercised a privacy right. Exercising your rights is protected and will have no adverse effect on your 399de account.

10. Data Security

399de implements technical and organisational measures to protect your personal data from unauthorised access, accidental loss, destruction, alteration, or disclosure. These measures include: SSL/TLS encryption for all data in transit; encryption at rest for sensitive data including identity documents and payment details; access controls restricting employee access on a need-to-know basis; regular security assessments and vulnerability testing of the 399de platform; and incident response procedures to detect, contain, and report security events promptly.

No internet platform can guarantee absolute security. While 399de maintains robust security practices, we cannot warrant that your data will never be compromised by an event outside our reasonable control. In the event of a data breach likely to risk your rights and freedoms, 399de will notify affected players promptly and take all reasonable steps to contain the breach and minimise harm.

11. Children's Privacy

399de is strictly an adult-only platform. We do not knowingly collect personal data from persons under 21 years of age. Registration requires confirmation that the player is aged 21 or older. If 399de discovers that data has been collected from a person under 21, we will immediately delete that data, close the associated account, and return any deposited funds to the payment method used, minus any forfeited bonus amounts. If you believe a person under 21 has registered on 399de, please contact [email protected] so we can investigate and act promptly.

12. Changes to This Privacy Policy

399de may update this Privacy Policy from time to time to reflect changes in our data practices, applicable law, or platform functionality. When we make a material change, we will update the Last updated date at the top of this page and, where the change significantly affects how we use your personal data, notify you via the platform's notification system or by SMS to your registered mobile number.

Your continued use of the 399de platform after a revised Privacy Policy is posted constitutes acceptance of the revised policy. If you do not accept the changes, cease using the platform and request account closure by emailing [email protected].

13. Contact Us

If you have questions about this Privacy Policy, wish to exercise a data right, or want to make a complaint about how 399de has handled your personal data, please contact our support team. We are committed to resolving all privacy-related enquiries promptly and transparently.
