oktk1 Privacy Policy — How We Handle Your Data

Your privacy matters to us. This policy explains exactly what personal data oktk1 collects, why we collect it, how we use it, and the rights you have over your own information.

Last updated: 1 January 2026

1. Introduction

This Privacy Policy ("Policy") describes how oktk1 ("oktk1", "we", "us", "our"), the operator of the online casino and sports betting platform at https://oktk1.bio, collects, processes, stores, and protects the personal data of users ("you", "your", "Player") who register for or use the Platform. This Policy forms part of our wider legal framework alongside the Terms and Conditions and Responsible Gaming Policy.

By creating an account or continuing to use the Platform, you acknowledge that you have read this Policy and consent to the collection and use of your personal data as described herein. If you do not consent, please do not use the Platform and contact us at [email protected] to request account closure. oktk1 is committed to handling your personal data with care, transparency, and in accordance with applicable data protection principles.

oktk1 does not sell your personal data to third parties. We share data only with trusted service partners directly necessary for operating the Platform, and only to the extent required for that purpose.

2. Data We Collect

oktk1 collects personal data through several means: directly from you when you register, make a deposit, contact support, or update your account; automatically through your use of the Platform; and from third-party service providers involved in payment processing, KYC verification, and fraud prevention. The categories of data we collect are described below:

👤

Identity & Registration Data

Full name, date of birth, mobile number, email address, and any government-issued identity document (National ID, passport) submitted during KYC verification.

💳

Financial & Payment Data

Transaction records (deposit amounts, withdrawal requests, dates, and reference numbers) and the mobile wallet identifiers (bKash, Nagad, Rocket, Upay) or card type (Visa, Mastercard) used. We do not store full card numbers or mobile wallet PINs.

📱

Device & Technical Data

IP address, device type, operating system, browser type, screen resolution, session timestamps, and approximate geographic location derived from IP. This data is collected automatically each time you access the Platform.

🎮

Gameplay & Betting Activity

Games played, bets placed, bet amounts, outcomes, bonus claims, session durations, and responsible gaming tool usage (e.g. deposit limits set, self-exclusion requests). This data is retained for regulatory compliance and responsible gaming monitoring.

📞

Communications Data

Records of your interactions with oktk1 support, including live chat transcripts, email correspondence, and any feedback or complaint submissions. These records are retained to ensure consistent service quality and to resolve disputes.

3. How We Use Your Data

oktk1 uses the personal data we collect for specific, legitimate purposes. We do not use your data for any purpose beyond what is described in this Policy without obtaining your prior consent. The primary purposes for which we process your data are:

  • Account management — to create, maintain, and secure your Player account, process login authentication, and enforce account-level limits or restrictions.
  • Payment processing — to facilitate deposits and withdrawals via your chosen payment method, verify payment authenticity, and maintain an accurate record of all financial transactions on your account.
  • KYC and age verification — to comply with our obligations to verify player identity and age before processing withdrawals, and to prevent underage gambling and financial fraud.
  • Responsible gaming — to monitor gameplay patterns for signs of problem gambling, enforce self-exclusion and deposit limits set by the player, and proactively contact players who display indicators of at-risk behaviour.
  • Customer support — to respond to queries, investigate complaints, resolve disputes, and improve the quality of our support service based on interaction history.
  • Platform improvement and fraud prevention — to analyse anonymised usage data to improve Platform performance and user experience, and to detect, investigate, and prevent fraudulent transactions, account abuse, and security incidents.

Where oktk1 wishes to use your data for direct marketing communications (such as promotional emails or in-Platform notifications about bonuses and offers), we will seek your explicit consent before doing so. You may withdraw marketing consent at any time by contacting [email protected] or adjusting your notification preferences in your account settings.

Every instance of personal data processing at oktk1 is grounded in one of the following recognised legal bases:

Basis A

Contractual Necessity

Processing is necessary to perform the contract between you and oktk1 — specifically, to operate your account, process your deposits and withdrawals, verify your identity, and deliver the gaming services you have registered to use. Without this processing, we cannot fulfil our obligations to you as a player.

Basis B

Legal Obligation

Certain processing activities — particularly KYC identity and age verification, transaction record-keeping, and the reporting of suspicious transactions — are required by applicable laws and regulatory requirements governing online gaming and financial services. oktk1 is obligated to perform this processing regardless of your preferences.

Basis C

Legitimate Interests

Where processing is not required by contract or law, oktk1 may process data on the grounds of legitimate interests — for example, fraud prevention, security monitoring, and Platform quality improvements. In each such case, we balance our interests against your rights and freedoms, and we do not process data where your interests override ours.

5. Cookies and Tracking Technologies

oktk1 uses cookies and similar technologies (such as local storage and session tokens) to operate the Platform, maintain your login session, remember your preferences, and improve Platform performance. The types of cookies we use include:

  • Essential cookies — required for the Platform to function. These include session authentication tokens and security cookies. They cannot be disabled without breaking core Platform functionality.
  • Functional cookies — used to remember your language preference, display settings, and last-visited game category so the Platform loads in a state familiar to you.
  • Analytics cookies — aggregated, anonymised data about how users navigate the Platform. This data does not identify individual users and is used solely to improve Platform design and performance.
  • Security cookies — used by our fraud detection systems to identify unusual login patterns, concurrent session anomalies, and other security signals that may indicate unauthorised access attempts.

You may adjust cookie preferences through your browser settings, but please note that disabling essential cookies will prevent you from logging in or using core Platform features. oktk1 does not use third-party advertising cookies or cross-site tracking cookies.

6. Data Sharing and Third Parties

oktk1 does not sell, rent, or trade your personal data with third parties for their own marketing or commercial purposes. We share your data only in the following limited circumstances:

  • Payment processors and mobile wallet providers (bKash, Nagad, Rocket, Upay, Visa, Mastercard) — solely to authorise and complete financial transactions initiated by you. These providers have their own privacy policies and are independently responsible for how they handle data on their own systems.
  • KYC and identity verification partners — third-party verification service providers who process submitted identity documents to confirm your name, age, and document authenticity. These providers are bound by confidentiality agreements and may only use your data for verification purposes.
  • Game content providers (Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, Ezugi) — limited gameplay session data is passed to game provider APIs to load and manage game rounds. These providers do not receive your identity or financial data.
  • Law enforcement and regulatory authorities — where oktk1 is legally required to disclose personal data in response to a lawful request from a competent authority, court order, or applicable legal obligation. oktk1 will notify you of such disclosures where permitted by law.

All third-party partners who receive your data are subject to data processing agreements with oktk1 that restrict their use of your data strictly to the purposes for which it was shared. We do not permit our partners to use your data for their own independent purposes.

7. Payment Data and Mobile Wallet Security

When you initiate a deposit or withdrawal via bKash, Nagad, Rocket, or Upay, the payment PIN entry and wallet authentication occur entirely within your mobile wallet application. oktk1 does not intercept, store, or have access to your mobile wallet PIN at any point in the transaction process. Our payment integration receives only a transaction reference and confirmation status from the mobile wallet gateway — the same data visible in your own transaction history in the wallet app.

For card payments via Visa or Mastercard, card data is handled exclusively by our PCI-DSS compliant payment gateway partner. Full card numbers are never transmitted to or stored on oktk1 servers. oktk1 retains only the card type (Visa/Mastercard) and the last four digits for display purposes in your transaction history.

8. Data Security

oktk1 implements technical and organisational security measures designed to protect your personal data against unauthorised access, disclosure, alteration, or destruction. Our security infrastructure includes SSL/TLS encryption for all data transmitted between your device and our servers, access controls that restrict internal access to personal data on a need-to-know basis, regular security audits and vulnerability assessments of the Platform, and secure encrypted storage for all sensitive identity and financial records.

While we take all reasonable precautions to protect your data, no digital system is completely immune to risk. In the unlikely event of a data breach that poses a risk to your rights and freedoms, oktk1 will notify affected players as soon as practicable, providing details of the nature of the breach, the data involved, and the steps we are taking to address it.

Your account password is stored in a hashed, salted format and is never visible to oktk1 staff. Never share your password with anyone — oktk1 support will never ask for your password in any communication channel.

9. Your Data Rights

As a user of the oktk1 Platform, you have the following rights in relation to your personal data. To exercise any of these rights, contact us at [email protected]. We will acknowledge your request within 5 business days and aim to respond in full within 20 business days (Bangladesh Standard Time, UTC+6).

  • 🔍 Right of access — you may request a copy of the personal data oktk1 holds about you, along with information about how it is used and with whom it has been shared.
  • ✏️ Right to rectification — if any personal data we hold about you is inaccurate or incomplete, you may request that it be corrected or updated. Minor corrections (such as a name spelling) can often be resolved directly through your account settings.
  • 🗑️ Right to erasure (right to be forgotten) — you may request the deletion of your personal data where it is no longer necessary for the purposes for which it was collected, subject to our legal obligations to retain certain records (such as financial transaction data required by applicable law).
  • ⏸️ Right to restriction of processing — you may request that we restrict the processing of your personal data in certain circumstances, such as while a correction request is being verified or while a data erasure request is under review.
  • 📦 Right to data portability — where processing is based on your consent or on a contract, you may request that we provide your personal data in a structured, commonly used, machine-readable format so that it can be transferred to another service provider.
  • 🚫 Right to object — you may object to processing based on legitimate interests (including profiling) at any time. You may also withdraw consent for marketing communications at any time without affecting the lawfulness of processing that occurred before withdrawal.

Please note that some rights are subject to limitations. For example, we cannot erase financial transaction records where we are legally required to retain them. Where we are unable to fulfil a request in full, we will explain the reason clearly in our response.

10. Data Retention

oktk1 retains your personal data only for as long as necessary to fulfil the purposes for which it was collected, or as required by applicable laws and regulatory obligations. The general retention periods applied are: active account data is retained for the duration of your account's active status plus a minimum of 5 years following account closure; financial transaction records are retained for a minimum of 5 years from the date of the transaction to comply with financial record-keeping obligations; KYC identity documents are retained for a minimum of 5 years following account closure; support and communications records are retained for 2 years from the date of the last interaction.

When data is no longer required under applicable retention obligations, oktk1 will securely delete or anonymise it so that it can no longer be attributed to you as an individual. Anonymised aggregate data (from which no individual can be identified) may be retained indefinitely for statistical and Platform improvement purposes.

11. Children's Privacy

The oktk1 Platform is strictly for adults aged 21 and above. We do not knowingly collect personal data from individuals under the age of 21. If we become aware that personal data has been collected from a person under 21, we will immediately delete that data and close the associated account. If you believe that a person under 21 has registered on the Platform, please notify us at [email protected] immediately so that we can investigate and take appropriate action.

12. Changes to This Privacy Policy

oktk1 reserves the right to update this Privacy Policy at any time. When material changes are made to this Policy, we will notify active players via email or an in-Platform notification prior to the changes taking effect. The "Last updated" date at the top of this page will always reflect the date of the most recent revision. We encourage you to review this Policy periodically to stay informed about how we protect your data.

Your continued use of the Platform after the effective date of any updated Policy constitutes your acceptance of the revised terms. If you disagree with any changes to this Policy, you should stop using the Platform and may request account closure by contacting [email protected].
