ck366 Privacy Policy
At ck366, your privacy is not an afterthought — it is a foundational commitment. This Privacy Policy explains in clear, formal terms exactly what personal data we collect from players in Bangladesh, why we collect it, how we use and protect it, and what rights you hold over your own information.
These six principles underpin every data decision ck366 makes — from the moment you register your account to every deposit and withdrawal you process.
Collect Only What We Need
ck366 collects the minimum personal data required to operate the Platform, verify player identities, process payments in BDT, and comply with applicable legal obligations. We do not collect data for its own sake, and we do not purchase data from third-party marketing brokers.
Purpose Limitation
Every piece of data ck366 holds about you is used exclusively for the purpose for which it was collected — account management, payment processing, identity verification, fraud prevention, and responsible gaming compliance. We do not repurpose your data for unrelated commercial activities without your explicit consent.
Security by Design
All data transmitted between your device and ck366 is protected by 256-bit SSL/TLS encryption — the same standard used by major Bangladeshi banks. Stored data is secured with access controls, encryption at rest, and regular security audits conducted by our dedicated security operations team.
No Unauthorised Sharing
ck366 does not sell, rent, or trade your personal data to any third party for their own commercial purposes. We share data only with vetted, contractually bound service providers who assist us in operating the Platform — such as payment processors, identity verification services, and fraud prevention partners.
Your Rights Are Real
You have the right to access, correct, and request deletion of the personal data ck366 holds about you. You also have the right to object to certain types of processing and to request a copy of your data in a portable format. ck366 will respond to all verified data rights requests within 30 days of receipt.
Defined Retention Periods
ck366 does not retain your personal data indefinitely. Retention periods are defined by the type of data and the legal obligation associated with it. Account data is retained for the duration of your relationship with ck366 plus a defined period thereafter to satisfy regulatory requirements. When data is no longer required, it is securely deleted or anonymised.
Important: This Privacy Policy ("Policy") describes how ck366 ("ck366", "we", "us", "our") collects, uses, stores, and protects the personal data of players ("you", "your") who access or use the ck366 platform at https://ck366.io. By registering an account or using any part of the Platform, you acknowledge that you have read and understood this Policy and consent to the data practices described herein. If you do not agree to this Policy, you must discontinue your use of the Platform immediately.
Introduction
ck366 is Bangladesh's leading online betting and casino platform, offering cricket betting, live casino games, slot titles, fishing games, and a wide range of sports markets to players across Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, and beyond. In the course of providing these services, ck366 necessarily collects and processes personal data belonging to the players who use the Platform.
ck366 takes its responsibilities as a data controller seriously. This Policy is written in plain, formal English to ensure that every player — regardless of their technical background — can understand what data we hold about them, why we hold it, and how it is protected. We encourage all players to read this Policy carefully and to contact us at [email protected] if any aspect of it is unclear.
This Policy should be read in conjunction with ck366's Terms & Conditions and Responsible Gaming Policy, both of which are incorporated by reference. In the event of a conflict between this Policy and any other document, this Policy shall prevail in respect of privacy and data protection matters.
Data Controller
For the purposes of this Privacy Policy, the data controller — that is, the entity responsible for determining the purposes and means of processing your personal data — is ck366, operating the Platform at https://ck366.io.
All enquiries relating to the collection, use, storage, or deletion of your personal data should be directed to the ck366 Data Protection contact at:
- Email: [email protected] (plain text — not a clickable link)
- Platform: https://ck366.io
- Support Hours: 24 hours a day, 7 days a week
ck366 will acknowledge all data-related enquiries within 5 business days and will respond substantively within 30 days of receiving a verified request.
Data We Collect
ck366 collects personal data in the following categories, depending on how you interact with the Platform:
3.1 Identity Data
This includes your full legal name, date of birth, nationality, and government-issued identification details (such as your National Identity Card number, passport number, or driver's licence number). Identity data is collected primarily for the purpose of age and identity verification.
3.2 Contact Data
This includes your registered email address, mobile phone number, and residential address (including district, city, and postcode). We use contact data to communicate with you about your account, transactions, promotions you have opted into, and important Platform updates.
3.3 Financial Data
This includes your registered payment method details — such as your bKash, Nagad, Rocket, or Upay mobile wallet number or bank account details used for deposits and withdrawals. ck366 does not store full card numbers or mobile banking PINs. Financial data is used exclusively to process deposits and withdrawals denominated in Bangladeshi Taka (BDT).
3.4 Transaction Data
This includes the complete history of all deposits, withdrawals, bets, wagers, and bonus credits associated with your ck366 account. Transaction data is retained to facilitate account management, resolve disputes, and fulfil our legal obligations.
3.5 Technical Data
This includes your IP address, device type, operating system, browser type and version, screen resolution, and connection data collected automatically when you access the Platform. Technical data is used for fraud prevention, security monitoring, and Platform performance optimisation.
3.6 Usage Data
This includes information about how you navigate and use the Platform — such as pages visited, games played, session duration, click paths, and feature interactions. Usage data is analysed in aggregate to improve the Platform's user experience and to deliver relevant content.
3.7 Communications Data
This includes the content of any communications you send to ck366 via live chat, email, or any other support channel, including transcripts of chat sessions, email correspondence, and records of any complaints or disputes submitted to ck366.
3.8 Responsible Gaming Data
Where you use ck366's responsible gaming tools — such as setting deposit limits, requesting a cooling-off period, or applying for self-exclusion — we retain records of those requests and the settings applied. This data is used solely to enforce your chosen protections and is never used for marketing purposes.

ck366 collects personal data through the following channels and methods:
- Direct submission: Data you actively provide when registering an account, completing verification, making a deposit or withdrawal, contacting support, or setting responsible gaming preferences.
- Automated collection: Technical and usage data collected automatically via cookies, server logs, and similar tracking technologies when you access and navigate the Platform.
- Third-party sources: Identity verification data confirmed or supplemented by our accredited identity verification providers, fraud prevention partners, and payment processors (such as bKash, Nagad, Rocket, and Upay).

You may withdraw your consent to marketing communications at any time by contacting [email protected] or by using the unsubscribe mechanism in any marketing message.
Sharing Your Data
ck366 does not sell, rent, or share your personal data with third parties for their own independent commercial purposes. We share your data only in the following limited circumstances:
7.1 Service Providers
ck366 engages trusted third-party service providers to assist in operating the Platform. These include payment processors (bKash, Nagad, Rocket, Upay), identity verification providers, fraud prevention and AML screening services, cloud hosting and infrastructure providers, and customer support technology vendors. All such providers are bound by contractual data processing agreements that restrict how they may use your data and require them to maintain appropriate security standards.
7.2 Legal and Regulatory Disclosure
ck366 may disclose your personal data to law enforcement authorities, regulatory bodies, or courts of competent jurisdiction where required to do so by applicable law, court order, or regulatory directive. ck366 will notify you of any such disclosure where it is legally permitted to do so.
7.3 Business Transfers
In the event of a merger, acquisition, restructuring, or sale of all or part of ck366's business, your personal data may be transferred to the acquiring entity as part of the transaction. ck366 will ensure that any such transfer is governed by appropriate data protection safeguards and will notify affected players prior to any transfer taking effect, where practicable.
7.4 Responsible Gaming Registries
Where you apply for self-exclusion from ck366, your details may be shared with responsible gaming registries or industry self-exclusion schemes of which ck366 is a member, for the purpose of giving effect to your self-exclusion request across participating platforms. This sharing is carried out in your direct interest and pursuant to your explicit request.

Data Retention

Data Security
ck366 implements a comprehensive set of technical and organisational security measures designed to protect your personal data against unauthorised access, accidental loss, destruction, alteration, or disclosure. These measures include:
- Encryption in transit: All data transmitted between your device and ck366 is protected by 256-bit SSL/TLS encryption, ensuring that your personal and financial data cannot be intercepted in transit.
- Encryption at rest: Sensitive data stored in ck366's systems — including identity documents, financial data, and account credentials — is encrypted at rest using industry-standard encryption algorithms.
- Access controls: Access to personal data within ck366's systems is restricted on a strict need-to-know basis. All staff with access to personal data undergo regular security training and are bound by confidentiality obligations.
- Intrusion detection: ck366's systems are monitored continuously by automated intrusion detection and prevention systems. Any anomalous activity triggers immediate investigation by our security operations team.
- Regular security audits: ck366's data security practices and infrastructure are subject to regular internal reviews and periodic third-party security assessments.
- Incident response: In the event of a confirmed data security incident that affects your personal data, ck366 will notify you in accordance with applicable legal requirements and will take immediate steps to contain, investigate, and remediate the incident.
While ck366 takes all reasonable precautions to protect your data, no online platform can guarantee absolute security. You are also responsible for maintaining the security of your own account — please use a strong, unique password and do not share your login credentials with any third party.
Your Data Rights
As a player on the ck366 Platform, you hold the following rights with respect to the personal data we hold about you. To exercise any of these rights, please contact us at [email protected] with the subject line "Data Rights Request" and your registered account username.

Children & Minors
ck366 is strictly an adults-only platform. The Platform is not directed at, and is not intended to be used by, any person under the age of 21. ck366 does not knowingly collect personal data from individuals under 21 years of age.
If ck366 becomes aware that personal data has been collected from a person under the age of 21, ck366 will take immediate steps to close the associated account, forfeit any balances held in accordance with the Terms & Conditions, and permanently delete the personal data collected. If you believe that a minor may have registered an account on ck366, please contact us immediately at [email protected] so that we can investigate and take appropriate action.
Marketing Communications
ck366 may send you marketing communications about promotions, bonuses, new game launches, and seasonal offers — such as those tied to Pohela Boishakh, Eid, or cricket BPL season — where you have provided your consent at the time of registration or at a later date.
ck366 will not send you unsolicited marketing communications. Each marketing communication will include a clear, functioning unsubscribe mechanism. You may also withdraw your consent to marketing communications at any time by:
- Clicking the "Unsubscribe" link in any marketing email sent by ck366.
- Replying "STOP" to any marketing SMS sent by ck366 to your registered mobile number.
- Contacting ck366 support at [email protected] with the subject line "Marketing Opt-Out".
Please note that withdrawing your consent to marketing will not affect the delivery of transactional communications — such as deposit confirmations, withdrawal notifications, and account security alerts — which are sent as part of the operational service and do not require separate consent.

ck366 reserves the right to update or amend this Privacy Policy at any time. When material changes are made to this Policy, ck366 will notify affected players by email to their registered email address and/or by displaying a prominent notice on the Platform prior to the changes taking effect.
The "Last Updated" date at the top of this Policy will be revised each time an update is published.
