399ok collects personal data through the following channels:
4.1 Directly From You
We collect data that you provide to us directly when you register a 399ok account via the 399ok Login registration form, complete KYC verification, make a deposit or withdrawal, place a bet, contact support, or respond to a survey or promotion.
4.2 Automatically Through Platform Use
When you access 399ok.io or use the 399ok application, our servers and analytics tools automatically record technical and usage data including your IP address, device information, session timestamps, and navigation behaviour. This data is collected using server-side logging, cookies, and similar tracking technologies.
4.3 From Payment Partners
When you make a deposit or withdrawal using bKash, Nagad, Rocket, or Upay, our payment processing partners may share transaction confirmation data with 399ok to allow us to credit your 399ok wallet or process your withdrawal. This data transfer is limited to what is strictly necessary for payment processing and account reconciliation.
4.4 From Identity Verification Services
Where 399ok uses third-party identity verification tools to assist with KYC document authentication, those providers may return a verification result and confidence score to 399ok. The underlying document images are processed in accordance with those providers' own data processing agreements.
4.5 From Third-Party Game Providers
Game providers integrated into the 399ok Casino platform — including Evolution Gaming, Pragmatic Play, NetEnt, Microgaming, Ezugi, and Spribe — may share session-level gaming data with 399ok for the purposes of wallet settlement, bonus tracking, responsible gaming monitoring, and fraud detection.
5. Legal Basis for Processing
399ok processes your personal data on the following legal grounds:
- Contractual Necessity: Processing your identity data, transaction data, and account credentials is necessary to provide the Services you have contracted for when you registered a 399ok account. Without this processing, we cannot operate your account, accept deposits, settle bets, or process withdrawals.
- Legitimate Interests: We process technical and device data, betting and gaming activity data, and communications data on the basis of our legitimate interests in operating a secure, fair, and financially sustainable platform — including fraud prevention, responsible gaming monitoring, platform improvement, and customer support quality management. We have assessed that these interests are not overridden by your privacy rights.
- Legal Obligation: We process identity and KYC documentation data in part to comply with applicable platform standards, anti-money-laundering obligations, and Know Your Customer requirements. We may be required to retain certain records and disclose them to relevant authorities.
- Consent: Where we send you direct marketing communications, we do so only on the basis of your consent, which you may withdraw at any time. We will not send marketing communications to you without your prior consent.
6. How We Use Your Data
399ok uses the personal data we collect for the following specific purposes:
6.1 Account Management
To create and maintain your 399ok account, authenticate your identity at each 399ok Login session, manage your wallet balance, process deposits and withdrawals, apply bonuses and promotions, and communicate with you about your account status.
6.2 Identity Verification & Fraud Prevention
To verify that you are aged 21 or above and that your account details are accurate through our KYC process. To detect, investigate, and prevent fraudulent transactions, money laundering, match-fixing, multi-accounting, and other prohibited activities as defined in the 399ok Terms & Conditions.
6.3 Sports Betting & Casino Services
To operate the sportsbook, including accepting bets on BPL, IPL, T20 World Cup, and other cricket markets; to settle bets in accordance with published rules; to manage the 399ok Casino lobby; and to connect your sessions to the third-party game providers whose titles are featured on the platform.
6.4 Responsible Gaming
To monitor your gaming and betting activity for indicators of problem gambling; to enforce deposit limits, session reminders, cooling-off periods, and self-exclusion requests that you activate; and to ensure that 399ok's responsible gaming obligations are met at a platform level.
6.5 Customer Support
To respond to your enquiries and complaints via live chat and email; to maintain records of your support interactions for quality assurance and dispute resolution purposes; and to fulfil our complaint escalation obligations under the Terms & Conditions.
6.6 Marketing (With Consent)
Where you have provided consent, to send you promotional offers, bonus notifications, BPL and IPL season promotions, Eid reload offers, and other marketing communications via email or platform notifications. You may withdraw this consent at any time by updating your communication preferences in your account settings or by contacting [email protected].
6.7 Platform Improvement & Analytics
To analyse aggregate usage patterns to improve the performance, design, and content of the 399ok platform; to test new features; and to optimise the betting and casino experience for Bangladeshi players. Analytics processing uses aggregated or pseudonymised data wherever possible.
No Automated Decision-Making: 399ok does not make solely automated decisions about you (i.e., decisions made without any human involvement) that have significant legal or similarly significant effects on you. Where automated tools are used in fraud detection or responsible gaming monitoring, a human review is available on request.
7. Data Sharing & Disclosure
399ok does not sell, rent, or trade your personal data to third parties for their own commercial purposes. We share your data only in the following limited circumstances:
7.1 Payment Service Providers
We share the minimum necessary transaction data with bKash, Nagad, Rocket, and Upay to process your deposits and withdrawals. These providers operate under their own privacy policies and are independently responsible for data they collect through their own platforms. 399ok does not store full mobile wallet account credentials on its servers.
7.2 Game Providers
To deliver casino and crash game sessions, we share a session token and wallet reference with third-party game providers including Evolution Gaming, Pragmatic Play, NetEnt, Microgaming, Ezugi, and Spribe. These providers receive only the data necessary to authenticate your game session and return results to the 399ok platform.
7.3 Identity Verification Partners
Where we use a third-party KYC or identity verification service, your identity documents and associated data are shared with that provider solely for the purpose of document authentication. We select verification partners that maintain data protection standards consistent with this Policy.
7.4 Legal & Regulatory Disclosure
399ok may disclose personal data to law enforcement authorities, government bodies, or other regulatory agencies where we are required to do so by applicable law, court order, or where we have a good-faith belief that disclosure is necessary to investigate fraud, money laundering, match-fixing, or other criminal activity involving 399ok's platform.
7.5 Business Transfers
In the event that 399ok undergoes a business restructuring, merger, acquisition, or sale of assets, your personal data may be transferred to the successor entity as part of that transaction. You will be notified of any such transfer via an in-platform notification or email to your registered address before the transfer takes effect.
We Do Not Sell Your Data: 399ok will never sell, rent, or otherwise commercially exploit your personal data to data brokers, advertisers, or unrelated third-party businesses. Your data is used exclusively for the purposes described in this Privacy Policy.
8. Cookies & Tracking Technologies
399ok uses cookies and similar technologies on the 399ok.io website and application to provide, secure, and improve our Services. A cookie is a small text file placed on your device when you visit our website. The following categories of cookies are used by 399ok:
8.1 Strictly Necessary Cookies
These cookies are essential for the 399ok platform to function. They maintain your 399ok Login session, store your wallet authentication token, preserve your language and display preferences, and enable the security features that protect your account. These cookies cannot be disabled without preventing you from using core platform functionality.
8.2 Performance & Analytics Cookies
These cookies collect anonymous, aggregated information about how players use the 399ok platform — for example, which betting markets are most visited, how long players spend in the casino lobby, and where technical errors occur. This data helps us improve platform performance and user experience. No personally identifiable information is transmitted via these cookies.
8.3 Functional Cookies
These cookies remember your preferences — for example, your preferred sports betting view, your default deposit method, and your responsible gaming settings — so that you do not need to re-enter them at each 399ok Login session.
8.4 Marketing & Attribution Cookies
Where you have consented to marketing communications, attribution cookies help us understand which promotional channel led you to 399ok, enabling us to measure the effectiveness of our campaigns and serve you relevant offers. You may opt out of marketing cookies at any time through your account settings.
Cookie Management: You can control and manage cookies through your browser settings. Disabling strictly necessary cookies will impair your ability to use the 399ok platform. Disabling other cookie categories will not prevent you from accessing 399ok but may reduce the personalisation of your experience.
9. Data Retention
399ok retains your personal data for as long as is necessary to fulfil the purposes set out in this Privacy Policy, and in accordance with our legal and compliance obligations. The following retention periods apply:
| Data Category | Retention Period | Reason |
|---|---|---|
| Account registration & identity data | Duration of account + 5 years post-closure | KYC compliance and fraud prevention records |
| KYC documents | Duration of account + 5 years post-closure | Anti-money-laundering record-keeping obligations |
| Financial & transaction data | 7 years from transaction date | Financial record-keeping and dispute resolution |
| Betting & gaming history | 5 years from activity date | Dispute resolution and responsible gaming monitoring |
| Technical & device logs | 12 months from collection | Security incident investigation |
| Support communications | 3 years from last interaction | Dispute resolution and quality assurance |
| Marketing consent records | Until consent withdrawn + 3 years | Evidence of consent for compliance purposes |
Where you request deletion of your personal data and no overriding legal retention obligation applies, 399ok will securely delete or anonymise your data within 30 days of receiving and validating your request.
10. Data Security
399ok takes the security of your personal data seriously and implements a range of technical and organisational measures to protect it against unauthorised access, loss, destruction, or alteration. These measures include:
- 256-bit SSL/TLS Encryption: All data transmitted between your device and the 399ok platform — including 399ok Login sessions, deposit and withdrawal requests, and personal data submissions — is encrypted using 256-bit SSL/TLS protocols.
- Password Hashing: Account passwords are never stored in plain text. 399ok uses industry-standard one-way hashing algorithms with unique salts to store password credentials securely.
- Access Controls: Access to personal data within 399ok's internal systems is restricted to authorised personnel on a strict need-to-know basis. All internal data access events are logged and subject to periodic audit.
- Two-Step Verification: 399ok offers two-step verification to all registered players as an additional layer of 399ok Login security. We strongly encourage all players to activate this feature.
- Penetration Testing: 399ok's platform undergoes regular security assessments to identify and remediate potential vulnerabilities before they can be exploited.
- Data Minimisation: 399ok collects and retains only the personal data that is genuinely necessary for the purposes described in this Policy. We do not retain data beyond the periods set out in Section 9.
Despite these measures, no internet-based platform can guarantee absolute security. In the event of a data security incident that is likely to result in a risk to your rights and freedoms, 399ok will notify affected players promptly and take immediate steps to mitigate the impact.
Your Role in Security: You play an important part in keeping your account secure. Choose a strong, unique password for your 399ok account, enable two-step verification, and never share your 399ok Login credentials with anyone. 399ok will never ask for your password via email, SMS, or live chat.
11. Your Rights
As a registered 399ok player, you hold the following rights in respect of the personal data that 399ok processes about you:
11.1 Right of Access
You have the right to request a copy of the personal data that 399ok holds about you, together with information about the purposes for which it is processed, the categories of data held, the recipients to whom it has been disclosed, and the retention period applied. 399ok will respond to subject access requests within 14 business days.
11.2 Right to Rectification
You have the right to request that 399ok corrects any inaccurate personal data we hold about you, or completes any incomplete data. You may update many of your account details directly through your 399ok account settings following 399ok Login. For changes to core identity data (name, date of birth), you will be asked to provide supporting documentation.
11.3 Right to Erasure
You have the right to request that 399ok deletes your personal data where it is no longer necessary for the purposes for which it was collected, where you have withdrawn your consent (where consent was the legal basis for processing), or where you object to the processing and there are no overriding legitimate grounds. This right is subject to 399ok's legal data retention obligations, which may require us to retain certain records even after account closure.
11.4 Right to Restriction of Processing
You have the right to request that 399ok restricts the processing of your personal data in certain circumstances — for example, while the accuracy of data you have contested is being verified, or while an objection to processing is being assessed.
11.5 Right to Data Portability
Where we process your personal data on the basis of your consent or contract performance, and where the processing is carried out by automated means, you have the right to receive a copy of your personal data in a structured, commonly used, machine-readable format.
11.6 Right to Object
You have the right to object to 399ok processing your personal data on the basis of legitimate interests, including for direct marketing purposes. If you object to direct marketing, 399ok will cease processing your data for that purpose immediately.

11.7 Right to Withdraw Consent
Where 399ok processes your personal data on the basis of your consent (for example, for marketing communications), you may withdraw that consent at any time without affecting the lawfulness of processing carried out before withdrawal. To withdraw consent, update your communication preferences in your account settings or contact [email protected].
To exercise any of the above rights, please contact 399ok via live chat or at [email protected]. We will acknowledge your request within 48 hours and respond in full within 14 business days. We may need to verify your identity before processing your request to ensure that personal data is not disclosed to an unauthorised party.
12. Children's Privacy
The 399ok platform is strictly intended for adults aged 21 years and above. 399ok does not knowingly collect, process, or store personal data from any individual under the age of 21. Age verification is a mandatory step in the 399ok registration and KYC process.
If 399ok becomes aware that personal data has been collected from an individual under the age of 21, that account will be immediately closed, all deposited funds will be returned to the source payment method where technically feasible, and all associated personal data will be securely deleted from our systems.
21+ Only: If you are a parent or guardian and believe that a person under the age of 21 has created a 399ok account using false information, please contact us immediately at [email protected]. We will investigate and take immediate action. Protecting minors from access to gambling platforms is a core responsibility that 399ok takes extremely seriously.
13. Third-Party Links & Integrations
The 399ok platform integrates with third-party services including payment processors and game providers as described elsewhere in this Policy. The 399ok website does not contain links to unrelated external websites. However, the third-party game providers and payment service providers whose services are accessible through the 399ok platform operate under their own privacy policies and data processing practices.
399ok is not responsible for the privacy practices of third-party game providers (Evolution Gaming, Pragmatic Play, NetEnt, Microgaming, Ezugi, Spribe) or payment service providers (bKash, Nagad, Rocket, Upay) in respect of data they collect independently through their own platforms. We encourage you to review the privacy policies of these providers directly where their services are relevant to you.
14. Marketing Communications
399ok may send you promotional communications about bonuses, seasonal offers (including BPL season promotions, Eid reload bonuses, T20 World Cup special markets, Pohela Boishakh offers, and Victory Day promotions), new game launches, and platform updates — but only where you have explicitly consented to receive such communications.
Each marketing email or notification we send will include a clear and easy mechanism to opt out of future communications. You may also manage your marketing preferences at any time through your 399ok account settings following 399ok Login, or by contacting [email protected]. Opting out of marketing communications will not affect your ability to use the 399ok platform or receive service-related communications about your account.
No Unsolicited Marketing: 399ok will never send you marketing communications without your prior consent. If you receive a communication claiming to be from 399ok that you did not consent to, please report it to [email protected] immediately.
15. Changes to This Privacy Policy
399ok reserves the right to update, amend, or replace this Privacy Policy at any time to reflect changes in our data processing practices, applicable legal requirements, or the services we offer. When material changes are made, we will notify registered players via email to their registered address or via an in-platform notification displayed at the time of their next 399ok Login session.
The updated Policy will be published on this page with a revised effective date at the top of the document. Your continued use of the 399ok platform following notification of any amendment constitutes your acceptance of the revised Privacy Policy. If you do not accept the revised Policy, you must cease using the platform and may request account closure by contacting our support team.
We encourage you to review this Privacy Policy periodically to stay informed about how 399ok protects your personal data.
