zk666 Privacy Policy
This Privacy Policy explains how zk666 collects, uses, stores, and protects your personal information when you use our platform. We are committed to handling your data with care and transparency.
Introduction
This Privacy Policy ("Policy") describes how zk666 ("the Platform", "we", "us", "our") collects, processes, stores, and protects the personal information of individuals ("you", "the Player", "the User") who register an account on or otherwise interact with the zk666 website at https://zk666.onl. This Policy forms part of our overall Terms and Conditions. By creating an account or using the Platform, you acknowledge that you have read and understood this Policy and consent to the processing of your personal data as described herein.
This Policy applies to all players accessing the Platform from any location in Bangladesh, including Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, Barisal, Rangpur, Mymensingh, and Cox's Bazar. If you do not agree with how we process your data as described in this Policy, please do not use the Platform. If you have questions about this Policy at any time, contact us at [email protected].
Privacy at a Glance
1. Information We Collect
When you register and use the zk666 platform, we collect personal information that falls into two broad categories: information you provide directly to us, and information collected automatically when you use the Platform. The following is a detailed list of the information we collect directly from you:
- Full name and date of birth — collected at registration for account creation and age verification purposes to confirm that you are aged 21 or above.
- Bangladeshi mobile number — your primary identifier on the Platform, used for account login, SMS verification codes, and withdrawal confirmation notifications.
- Government-issued identity document details — collected as part of KYC (Know Your Customer) verification before your first withdrawal. This may include your National ID (NID) number and a scanned copy or photograph of the document.
- Mobile banking account details — the bKash, Nagad, Rocket, or Upay account number registered in your name, used to process deposits and withdrawals. We verify that this number matches the name on your zk666 account.
- Support communications — any messages, emails, or chat transcripts exchanged between you and the zk666 support team, retained to maintain a record of account-related queries and resolutions.
In addition to the information you provide directly, the Platform automatically collects the following technical and behavioural data when you access or use zk666:
- Device and browser information — device type, operating system version, browser type and version, screen resolution, and language settings, collected to ensure the Platform renders correctly on your device.
- IP address and approximate location — used for fraud detection, responsible gaming compliance (including restricting access from jurisdictions where online gambling is prohibited), and session security.
- Game activity and session data — records of games played, bets placed, deposit and withdrawal history, and session durations. This data is used for account management, dispute resolution, bonus tracking, and responsible gaming monitoring.
2. How We Use Your Information
The specific purposes for which we process your personal data are as follows:
- Account creation and management — to register your account, maintain your account profile, authenticate your login sessions, and provide you with access to the Platform's features.
- Identity and age verification — to confirm that you are aged 21 or above, that you are who you say you are, and that your account details are consistent with your KYC documents. This is a mandatory compliance step before any withdrawal is processed.
- Payment processing — to initiate, complete, and reconcile your deposits and withdrawals via bKash, Nagad, Rocket, or Upay. Transaction records are maintained for accounting, audit, and dispute resolution purposes.
- Fraud prevention and security — to detect and investigate suspicious account activity, prevent money laundering, verify the legitimacy of transactions, and protect the integrity of the Platform for all users.
- Responsible gaming compliance — to monitor gameplay patterns that may indicate problematic gambling behaviour, to enforce self-imposed deposit limits and exclusion periods, and to ensure that players under 21 are not able to access the Platform.
- Customer support — to respond to your account queries, investigate complaints, and resolve disputes. Support correspondence is retained for a reasonable period to maintain a full record of communications.
Service improvement — aggregated and anonymised data about Platform usage patterns may be analysed to understand how players use zk666 and to inform future improvements. This analysis does not involve reviewing personally identifiable data at the individual level.
3. Sharing Your Information
zk666 does not sell or rent your personal data to third parties. We may share your personal data with the following categories of third parties, but only to the extent necessary for the delivery of our services:
- Payment processors — bKash, Nagad, Rocket, and Upay receive the transaction data necessary to process your deposits and withdrawals. These providers operate under their own privacy and data security frameworks as regulated mobile financial service providers in Bangladesh.
- Game content providers — Pragmatic Play, Evolution Gaming, Spribe, NetEnt, Microgaming, Ezugi, and other game studios whose content is displayed on zk666 may receive anonymised session identifiers necessary for game delivery and RNG audit purposes. These providers do not receive your full personal profile.
- Fraud prevention and compliance partners — zk666 may share data with third-party identity verification and fraud detection services where required to fulfil our compliance obligations, including KYC and anti-money laundering checks.
- Regulatory and law enforcement authorities — if we are required by applicable law, court order, or regulatory direction to disclose your personal data, we will do so. Where legally permitted, we will attempt to notify you of such a requirement in advance.
zk666 does not transfer your personal data to parties outside of these categories. Any service provider who receives your data on our behalf is contractually required to handle it securely, use it only for the purpose for which it was shared, and not to retain it beyond the period required to fulfil that purpose.
4. Payment Data and Mobile Banking
All financial transactions on zk666 are conducted via Bangladesh's mobile banking infrastructure: bKash, Nagad, Rocket, and Upay. When you make a deposit or request a withdrawal, zk666 records the transaction amount, the mobile banking account number used, the transaction reference number provided by the mobile banking provider, and the date and time of the transaction. This data is retained for account reconciliation, audit, and dispute resolution purposes.
zk666 does not store your full mobile banking PIN, password, or one-time passcode (OTP). These credentials are entered directly into your mobile banking app and are never transmitted to or stored on the zk666 platform. We store only the reference data described above, which allows us to verify that a transaction occurred without retaining the credentials that authorise access to your mobile banking account.
5. Cookies and Tracking Technologies
The zk666 platform uses cookies and similar lightweight tracking technologies to maintain your login session, remember your preferences, and collect anonymised analytical data about how the Platform is used. The types of cookies we use are:
- Essential cookies — strictly necessary for the Platform to function. These include session cookies that keep you logged in during your visit and security tokens that protect your account from cross-site request forgery attacks. These cookies cannot be disabled without affecting your ability to use the Platform.
- Functional cookies — cookies that remember your settings and preferences across sessions, such as your chosen language version of the site, so you do not have to re-select these settings each time you visit.
- Analytics cookies — anonymised data about page views, session lengths, and navigation paths on the Platform. This data is used in aggregate form to understand how the Platform is used and to identify areas for improvement. Individual players are not identified in analytics reports.
You may disable non-essential cookies through your mobile browser settings. Please note that disabling essential cookies will prevent you from logging in to your zk666 account. zk666 does not use third-party advertising cookies or cross-site tracking pixels.
6. Data Security
zk666 employs industry-standard technical and organisational measures to protect your personal data against unauthorised access, accidental loss, destruction, and alteration. These measures include SSL/TLS encryption for all data in transit, access controls limiting which personnel can view personal data, secure server infrastructure, and regular internal security reviews. While no digital platform can guarantee absolute security, zk666 takes its data protection obligations seriously and updates its security practices in response to emerging threats.
In the event of a data breach that is likely to result in a risk to your rights or interests, zk666 will notify affected players as promptly as practicable and will take immediate steps to contain and remediate the breach. You can help protect your account by keeping your login credentials confidential, logging out after each session, and promptly reporting any suspicious activity to [email protected].
7. Data Retention
zk666 retains your personal data for as long as your account is active and for a reasonable period thereafter as required for legal, regulatory, audit, and dispute resolution purposes. Specifically: account registration data and KYC documents are retained for a minimum of five years following account closure to meet standard anti-money laundering record-keeping requirements; transaction records are retained for a minimum of five years; support correspondence is retained for two years from the date of the last communication in each support thread.
If you request deletion of your account, we will deactivate your access to the Platform promptly. However, we are obliged to retain certain records (transaction history, KYC documents, support correspondence) for the retention periods described above even after your account is deactivated, as required by our compliance obligations. Data that is no longer required for any legitimate purpose will be securely deleted or anonymised.
8. Your Rights
As a player on the zk666 platform, you have the following rights in relation to your personal data. To exercise any of these rights, contact us at [email protected] with your registered mobile number and a description of the request:
- Right of access — you may request a copy of all personal data we hold about you. We will provide this within 30 days of a verified request.
- Right of rectification — if any personal data we hold about you is inaccurate or incomplete, you may ask us to correct or update it. Account details such as your registered name or date of birth may require supporting documentation before they can be amended.
- Right to erasure — you may request deletion of your personal data and closure of your account. We will fulfil this request subject to our legal obligation to retain certain records for compliance and audit purposes as described in the Data Retention section above.
- Right to restrict processing — in certain circumstances you may ask us to restrict the processing of your personal data, for example while a rectification request is being reviewed.
- Right to object to marketing — if you have opted in to receive promotional communications from zk666, you may withdraw that consent at any time by updating your account preferences or by contacting [email protected].
All rights requests are handled by the zk666 support team. We will verify your identity before processing any request that results in disclosure, modification, or deletion of personal data. Requests are handled within 30 days. If we are unable to fulfil a request due to a legal obligation, we will explain the reason in our response.
9. Children and Minors
The zk666 platform is strictly intended for adults aged 21 and above. We do not knowingly collect personal data from any person under the age of 21. Registration requires confirmation that the applicant is aged 21 or above, and KYC verification is used to enforce this requirement. If we discover that personal data has been collected from a person under the age of 21, we will immediately suspend the associated account, delete the personal data collected, and forfeit any balance held in the account.
If you are a parent or guardian and believe that a person under the age of 21 has registered an account on zk666 using their personal details or yours, please contact us immediately at [email protected]. We will investigate the matter and take appropriate action without delay.
10. Changes to This Privacy Policy
zk666 reserves the right to update or revise this Privacy Policy at any time. When we make material changes to this Policy, we will update the "Last Updated" date at the top of this page. For significant changes that affect your rights or how we process your personal data in a materially different way, we will make reasonable efforts to notify you directly via SMS or the contact information held on your account.
Your continued use of the zk666 Platform after any update to this Policy constitutes your acceptance of the revised Policy. If you do not agree with the revised Policy, you should stop using the Platform and may request closure of your account by contacting [email protected]. We encourage you to review this page periodically so that you are always aware of how your data is being handled.
