oknn Privacy
Policy
At oknn, the privacy and security of your personal information is a foundational commitment — not an afterthought. This Privacy Policy explains precisely what data we collect when you use oknn.win, how that data is used and protected, who it may be shared with, and what rights you hold over your own information as a player based in Bangladesh.

All data transmitted between your device and oknn.win is protected by 256-bit SSL/TLS encryption. Your login credentials, payment details, and personal information are never transmitted in plain text.
KYC Data Handled Securely
Identity documents submitted for KYC verification are stored in an encrypted document vault with restricted staff access. Documents are reviewed by trained compliance personnel only and are never shared with advertisers.
No Third-Party Data Sales
oknn does not sell, rent, or barter your personal data to any third-party marketing organisation, data broker, or advertising network. Your information stays within the oknn platform ecosystem.
Transparent Cookie Use
oknn uses only functional, analytics, and session cookies necessary to operate the platform. No invasive third-party advertising cookies are placed without your knowledge. You can manage cookie preferences in your browser settings at any time.

oknn retains your personal data only for as long as is necessary to fulfil the purpose for which it was collected, comply with legal obligations, or resolve disputes. Once the retention period expires, data is securely deleted or anonymised.
Your Rights Are Respected
You hold clear rights over your personal data including the right to access, correct, export, and request deletion of information we hold about you. Submit a data request at any time by contacting .
Data We Collect
When you interact with the oknn platform — whether by browsing oknn.win, registering an account, making a deposit, placing a wager, or contacting our support team — oknn collects certain categories of personal information.

How We Use Your Data
oknn processes your personal data only for clearly defined and legitimate purposes. We do not use your data in ways that are incompatible with the purposes described at the time of collection. The following outlines the primary purposes for which your data is used, along with the legal basis for each processing activity.
- Account Management and Service Delivery: We use your registration data to create and maintain your oknn account, authenticate your identity during oknn Login sessions, process deposits and withdrawals, apply bonuses and promotional awards, and maintain an accurate record of your betting and gaming history.
- Identity Verification and KYC Compliance: Your identity and address verification documents are processed to confirm that you meet the eligibility requirements set out in our Terms & Conditions — including the 18+ age requirement — and to comply with applicable anti-money-laundering (AML) standards. This processing is necessary for the performance of our contractual obligations to you and for compliance with legal requirements.
- Payment Processing: Your financial details are used solely to execute the deposit and withdrawal instructions you submit through the oknn cashier. Payment data is transmitted to our payment partners (bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, and card processors) only to the minimum extent necessary to complete the transaction.
- Fraud Prevention and Security: We analyse device data, IP addresses, login patterns, and transaction behaviour to detect and prevent fraudulent activity, money laundering, multi-accounting, and other prohibited conduct as defined in our Terms & Conditions.
- Responsible Gaming Monitoring: Usage data — including session frequency, session duration, deposit frequency, and wagering patterns — is monitored to identify potential signs of problem gambling behaviour. Where indicators are detected, our responsible gaming team may reach out to offer support resources.
- Customer Support: Communications you send to the oknn support team are used to resolve your queries, investigate disputes, process complaints, and improve the quality of our support services.
- Marketing Communications (with consent only): Where you have explicitly opted in to receive promotional communications from oknn, we may use your email address or mobile number to send you information about bonuses, new game launches, seasonal promotions (such as those tied to BPL cricket, Eid, or Pohela Boishakh), and other offers. You may withdraw this consent at any time by contacting or by following the unsubscribe instructions in any marketing message.
- Platform Improvement and Analytics: Aggregated and anonymised usage data is analysed to understand how players interact with the oknn platform, identify areas for improvement, and develop new features and content.
Cookies & Tracking Technologies
oknn uses cookies and similar tracking technologies to ensure the platform functions correctly, to remember your preferences between sessions, and to gather aggregate analytics data that helps us understand how players use oknn.win. This section explains what types of cookies we use and how you can manage them.
Types of cookies used on oknn.win:
- Strictly Necessary Cookies: These cookies are essential for the platform to function. They enable core features such as session authentication (keeping you logged in during your oknn Login session), security token validation, and load balancing. Without these cookies, key features of the platform would not operate correctly. These cookies cannot be disabled.
- Functional Cookies: These cookies remember choices you make on the platform — such as your preferred language display, last-visited game category, or responsible gaming limit settings — so that you do not need to re-enter them on every visit.
- Analytics Cookies: oknn uses anonymised analytics data (collected via first-party analytics tools) to understand which pages are most visited, how players navigate between sections such as the casino lobby, cricket betting markets, and slots pages, and how long players spend in each area. This data is aggregated and does not identify you as an individual.
- Security and Fraud Detection Cookies: These cookies are used to identify and flag unusual or suspicious activity patterns — such as multiple rapid login attempts from different locations — as part of our fraud prevention infrastructure.
You may control cookie settings through your browser's built-in privacy controls. Most modern browsers allow you to view, block, or delete individual cookies. Please note that disabling strictly necessary cookies will impair the functionality of the oknn platform, and some features — including maintaining your logged-in session — may not work correctly if essential cookies are blocked.
Data Sharing & Third Parties
oknn does not sell, rent, or trade your personal data to third parties for commercial purposes. However, in order to operate the platform effectively and comply with our legal obligations, we share limited personal data with a small number of trusted third-party service providers and authorities, as described below.
Categories of third parties with whom oknn may share your data:
- Payment Service Providers: When you make a deposit or request a withdrawal, the minimum necessary payment details are transmitted to the relevant payment partner — such as bKash, Nagad, Rocket, Upay, or our card processing provider — solely to execute the transaction. These providers process your data under their own privacy policies and are contractually required to maintain the security of any data shared with them.
- Game Content Providers: Third-party game studios integrated into the oknn platform — including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi — may receive a player session token and anonymised game-history data necessary to deliver their game content and maintain RNG audit logs. These providers do not receive your full name, contact details, or payment information.
- Identity Verification Services: Where oknn employs third-party KYC technology to automate document verification, your identity documents may be processed by that provider's secure verification infrastructure. All such providers are contractually bound to process your documents solely for the purposes of identity verification and to delete them upon completion of the verification process.
- Legal and Regulatory Authorities: oknn will disclose personal data to law enforcement agencies, regulatory bodies, financial intelligence units, or courts where required to do so by applicable law, or where disclosure is necessary to prevent or investigate fraud, money laundering, or other criminal activity. In such cases, we will disclose only the minimum data required by the lawful request.
- Professional Advisors: In the context of legal proceedings, audits, or corporate transactions, oknn's legal counsel, auditors, or other professional advisors may have access to relevant personal data under strict confidentiality obligations.
Data Security & Storage
Protecting the personal data of oknn players is a core operational priority. We implement a layered security architecture combining technical, organisational, and procedural controls designed to prevent unauthorised access, accidental loss, disclosure, alteration, or destruction of your personal information.
Technical security measures in place at oknn:
- Transport Layer Security: All data in transit between your browser or mobile device and oknn.win is encrypted using TLS 1.2 or higher, enforced via a valid SSL certificate. The oknn.win domain is served exclusively over HTTPS.
- Data Encryption at Rest: Sensitive personal data stored in oknn's databases — including identity verification documents, financial records, and authentication credentials — is encrypted at rest using AES-256 encryption.
- Access Controls: Access to personal data within oknn's internal systems is governed by strict role-based access controls. Only authorised personnel with a documented business need may access player data, and all access is logged and audited.
- Password Security: Account passwords are stored using a one-way cryptographic hashing algorithm. oknn staff cannot view your plaintext password at any time. If you forget your password, a secure reset process is triggered — your password is never retrieved or transmitted in plain form.
- Intrusion Detection: oknn's infrastructure is monitored around the clock using automated intrusion detection systems that flag and escalate anomalous access patterns for human review.
- Penetration Testing: The oknn platform undergoes regular independent security assessments to identify and remediate potential vulnerabilities before they can be exploited.
In the event of a personal data breach that is likely to result in a risk to your rights and freedoms, oknn will take prompt remedial action and notify affected players by email as soon as practicably possible, providing details of the nature of the breach, the data affected, and the steps being taken to mitigate any harm.

Please note that this right is subject to legal retention obligations — for example, financial transaction records must be retained for a minimum period under applicable anti-money-laundering regulations, and such records cannot be deleted before the retention period expires.
- Right to Restrict Processing: In certain circumstances — such as where you contest the accuracy of your data or object to a particular processing activity — you may request that oknn restrict the processing of your data while the matter is being resolved.
- Right to Data Portability: Where processing is based on your consent or on contractual necessity, you have the right to receive your personal data in a structured, commonly used, machine-readable format so that it can be transferred to another service provider.
