zz661 Privacy Policy
At zz661, protecting your personal data is not an afterthought — it is a core part of how we operate. This Privacy Policy explains exactly what information we collect, why we collect it, how we use and protect it, and what rights you have over your own data as a user of Bangladesh's premier online casino platform.
How We Treat Your Personal Data
Six core commitments guide every data decision we make at zz661. These are not aspirations — they are operational standards enforced across all teams and systems.
Secure by Default
All data transmitted between your device and our servers is encrypted using 256-bit SSL technology. We apply industry-standard security controls including firewalls, access logging, and intrusion detection to safeguard your account data at all times.
Minimal Collection
We collect only the data that is strictly necessary to provide our services, process your transactions, verify your identity, and comply with our legal obligations. We do not collect data speculatively or for purposes beyond those stated in this policy.
No Data Selling
zz661 does not sell, rent, or trade your personal information to third parties for their own marketing or commercial purposes. Your data is used solely to operate your account and improve your experience on the platform.
Transparency First
We tell you clearly what data we hold, why we hold it, and who we may share it with. There are no hidden data practices at zz661. This Privacy Policy is written in plain English so every user can understand their rights and our obligations.
Your Control
You have meaningful rights over your own data — including the right to access, correct, delete, or restrict its use. We make it straightforward to exercise these rights by contacting our support team at any time via email.
Defined Retention
We do not hold your data indefinitely. Retention periods are defined for each data category and aligned with our legal and operational requirements. Once the retention period expires, your data is securely deleted or anonymised.
Summary: This Privacy Policy describes how zz661 ("we", "us", "our") collects, processes, stores, and protects the personal data of users ("you", "your") who access the zz661 platform at https://zz661.io. By registering an account or using our services, you confirm that you have read and understood this policy. For questions, contact us at [email protected].
Introduction
zz661 is Bangladesh's premier online betting and casino platform, offering cricket sportsbook, live casino games, slots, and local favourites such as Teen Patti and Andar Bahar. We are fully committed to protecting the privacy and personal data of every user who interacts with our platform.
This Privacy Policy applies to all personal data collected by zz661 through the website at https://zz661.io, any associated mobile interfaces, our customer support channels, promotional communications, and any other service offered under the zz661 brand (collectively, the "Platform"). It applies to all registered users, including those located in Dhaka, Chittagong, Sylhet, Khulna, Rajshahi, Barisal, Rangpur, Mymensingh, and Cox's Bazar, as well as any other Bangladeshi users who access the Platform.
This policy should be read alongside our Terms & Conditions and our Responsible Gaming page, both of which are incorporated by reference. By accessing or using the Platform, you acknowledge that you have read and agree to the data practices described in this Privacy Policy. If you do not agree, please discontinue use of the Platform immediately.
Effective Date: This Privacy Policy is effective as of 1 January 2026. The most recent version will always be available at https://zz661.io/privacy-policy. Please review it periodically, as it may be updated in accordance with Section 12 below.
Data We Collect
We collect personal data from you in three ways: directly from you when you interact with the Platform, automatically when you access the Platform, and from third parties where permitted. The categories of personal data we collect are set out in the table below.
| Category | Examples | How Collected |
|---|---|---|
| Identity Data | Full name, date of birth, National ID number, passport number, photograph | Provided by you during registration and KYC verification |
| Contact Data | Email address, mobile phone number, residential address | Provided by you during registration or account updates |
| Financial Data | bKash / Nagad / Rocket / Upay account numbers, bank account details, transaction history, deposit and withdrawal amounts in BDT | Provided by you when making deposits or withdrawals; generated by Platform transactions |
| Technical Data | IP address, device type, browser type and version, operating system, screen resolution, time zone | Collected automatically when you access the Platform |
| Usage Data | Pages visited, games played, bets placed, session duration, click paths, feature interactions | Collected automatically via server logs and analytics tools |
| Communications Data | Support chat transcripts, email correspondence, feedback submissions | Provided by you when contacting our support team |
| Responsible Gaming Data | Deposit limit settings, self-exclusion status, cooling-off period history, session time alerts | Generated when you use responsible gaming tools on the Platform |
2.1 Special Category Data
We do not intentionally collect special category data (such as health information, religious beliefs, or biometric data) unless you volunteer it — for example, if you contact us to discuss a gambling-related health concern. Any such data is treated with the highest level of care and is used only to provide the support you have requested.
2.2 Data You Choose Not to Provide
Where providing certain personal data is optional, declining to provide it may limit your access to specific features. For example, failure to complete KYC verification will prevent you from processing withdrawals, as set out in our Terms & Conditions.
How We Use Your Data
zz661 uses your personal data only for the purposes described below. We do not use your data for any purpose that is incompatible with the reason it was originally collected without first obtaining your consent.
- Account Management: To create, maintain, and manage your zz661 account, including processing registration details, managing login credentials, and handling account settings and preferences.
- Transaction Processing: To process deposits and withdrawals via bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank, and other accepted payment methods. All transaction amounts are denominated in Bangladeshi Taka (BDT).
- Identity Verification (KYC): To verify your identity and age (21+ requirement), confirm ownership of payment methods, and comply with our anti-money laundering obligations.
- Service Delivery: To provide access to casino games, cricket sportsbook, live casino, slots, and all other Platform services. To personalise your experience and recommend games relevant to your playing history.
- Customer Support: To respond to your queries, complaints, and support requests submitted via email or live chat. To maintain a record of communications for quality assurance and dispute resolution.
- Responsible Gaming: To monitor gameplay patterns for signs of problem gambling, enforce deposit limits and self-exclusion settings, and contact users who may benefit from responsible gaming resources.
- Security and Fraud Prevention: To detect, investigate, and prevent fraudulent activity, money laundering, bonus abuse, multi-accounting, and other prohibited conduct as defined in our Terms & Conditions.
- Platform Improvement: To analyse usage patterns, test new features, and improve the performance, reliability, and user experience of the Platform.
- Legal Compliance: To comply with applicable laws, regulations, court orders, and requests from competent authorities.
- Marketing Communications: To send you promotional offers, bonus notifications, and news about zz661 — only where you have provided consent or where we have a legitimate interest. You may opt out of marketing communications at any time by contacting [email protected].
Marketing Opt-Out: If you no longer wish to receive promotional emails or SMS notifications from zz661, you can opt out at any time by emailing [email protected] with the subject line "Unsubscribe". Opting out of marketing will not affect your ability to use the Platform or receive transactional communications (such as deposit confirmations and withdrawal updates).
Legal Basis for Processing
Every data processing activity carried out by zz661 is grounded in one or more of the following legal bases:
- Contract Performance: Processing is necessary to fulfil our contractual obligations to you under the Terms & Conditions — for example, to operate your account, process transactions, and deliver Platform services.
- Legal Obligation: Processing is required to comply with legal obligations applicable to zz661 — for example, identity verification (KYC), anti-money laundering checks, and record-keeping requirements.
- Legitimate Interests: Processing is necessary for our legitimate business interests, provided those interests are not overridden by your rights and freedoms — for example, fraud prevention, Platform security, and service improvement.
- Consent: Where we rely on your consent as the legal basis — for example, for direct marketing communications — you may withdraw that consent at any time without affecting the lawfulness of processing carried out before withdrawal.
- Vital Interests: In exceptional circumstances, we may process data to protect the vital interests of a user — for example, where responsible gaming concerns require immediate intervention.
Cookies & Tracking Technologies
zz661 uses cookies and similar tracking technologies to operate and improve the Platform. A cookie is a small text file placed on your device when you access a website. We use the following types of cookies:
5.1 Essential Cookies
These cookies are strictly necessary for the Platform to function. They enable core features such as user authentication, session management, security token validation, and load balancing. The Platform cannot function properly without these cookies, and they cannot be disabled.
5.2 Analytics Cookies
We use analytics cookies to collect aggregated, anonymised information about how users interact with the Platform — such as which pages are visited most frequently, how long users spend in specific sections, and where users navigate from. This data helps us identify areas for improvement and optimise user experience. No personally identifiable information is stored in analytics cookies.
5.3 Functional Cookies
Functional cookies remember your preferences — such as your preferred language, display settings, and game lobby filters — so that you do not need to reset them each time you visit. These cookies improve convenience but are not essential to Platform operation.
5.4 Security Cookies
Security cookies help us detect and prevent fraudulent activity, including bot traffic, credential-stuffing attacks, and suspicious login patterns. These cookies are classified as essential and cannot be disabled.
Managing Cookies: You can control non-essential cookies through your browser settings. Most modern browsers allow you to refuse or delete cookies. Note that disabling certain cookies may affect the functionality of the Platform. For full details on cookie management, consult your browser's help documentation.
Data Sharing & Disclosure
zz661 does not sell or rent your personal data to third parties. We may share your data with the following categories of recipients only to the extent necessary for the purposes described in this Privacy Policy:
6.1 Payment Service Providers
To process deposits and withdrawals, we share relevant financial data with your chosen payment provider — such as bKash, Nagad, Rocket, Upay, Dutch-Bangla Bank (DBBL), City Bank, BRAC Bank, or Islami Bank. Each provider processes your data in accordance with their own privacy policies and applicable financial regulations.
6.2 Identity Verification Partners
To complete KYC verification, we may share identity documents (such as National ID scans) with trusted third-party identity verification service providers. These partners are bound by strict data processing agreements and may not use your data for any purpose other than identity verification on behalf of zz661.
6.3 Game Technology Providers
The games available on the Platform are supplied by licensed third-party studios including Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, and Ezugi. These providers may receive limited technical data (such as session tokens and game round identifiers) necessary to operate game rounds. They do not receive your personal identity or financial data beyond what is required for game integrity purposes.
6.4 Legal and Regulatory Authorities
We may disclose your personal data to competent governmental, regulatory, or law enforcement authorities where we are legally required to do so — for example, in connection with anti-money laundering investigations, court orders, or lawful requests from public authorities. We will notify you of such disclosure where we are legally permitted to do so.
6.5 Business Transfers
In the event that zz661 undergoes a merger, acquisition, asset sale, or restructuring, your personal data may be transferred to the acquiring entity as part of that transaction. You will be notified of any such transfer and given the opportunity to object where applicable law requires.
No Third-Party Marketing: zz661 does not share your personal data with advertisers, data brokers, or any other third parties for their own marketing or commercial purposes. All data-sharing arrangements are strictly limited to operational necessity and legal obligation.
Data Retention
We retain your personal data for as long as is necessary to fulfil the purposes for which it was collected, or as required by applicable law. The table below sets out our standard retention periods for the principal data categories:
| Data Category | Retention Period | Reason |
|---|---|---|
| Account & Identity Data | Duration of account + 5 years after closure | Legal and regulatory compliance, dispute resolution |
| Financial Transaction Data | 7 years from transaction date | Anti-money laundering obligations, financial record-keeping |
| KYC Documents | 5 years from account closure | Regulatory compliance, identity verification records |
| Support Communications | 3 years from last interaction | Quality assurance, dispute resolution |
| Technical & Usage Data | 13 months from collection | Platform analytics, fraud detection |
| Responsible Gaming Records | Duration of account + 7 years | Duty of care compliance, self-exclusion enforcement |
| Marketing Consent Records | Until consent withdrawn + 3 years | Demonstrating lawful basis for marketing |
Upon expiry of the applicable retention period, personal data is securely deleted or irreversibly anonymised so that it can no longer be linked to an individual. Where anonymised data is retained for statistical or analytical purposes, it no longer constitutes personal data under applicable data protection standards.
Data Security
zz661 implements a comprehensive suite of technical and organisational security measures to protect your personal data against unauthorised access, loss, destruction, or disclosure. Our security framework includes the following controls:
- Encryption in Transit: All data transmitted between your browser or mobile device and our servers is encrypted using TLS 1.2 / 1.3 (256-bit SSL). Our servers present valid SSL certificates and enforce HTTPS exclusively — unencrypted HTTP connections are redirected automatically.
- Encryption at Rest: Sensitive personal data fields — including identity documents, financial account references, and KYC records — are encrypted at the database level using industry-standard symmetric encryption algorithms.
- Access Controls: Access to personal data within our internal systems is restricted on a strict need-to-know basis. All staff with access to personal data undergo data protection training. Access is authenticated using multi-factor authentication and is logged for audit purposes.
- Firewall and Intrusion Detection: Our infrastructure is protected by enterprise-grade web application firewalls, DDoS mitigation systems, and real-time intrusion detection and prevention systems (IDS/IPS).
- Penetration Testing: We engage qualified security professionals to conduct regular penetration tests and vulnerability assessments of our Platform infrastructure and application code.
- Incident Response: We maintain a documented data breach response plan. In the event of a personal data breach that is likely to result in a risk to your rights and freedoms, we will notify you without undue delay using the contact details associated with your account.
Your Responsibility: While we take extensive steps to protect your data, account security also depends on you. Choose a strong, unique password for your zz661 account. Never share your login credentials with anyone. If you suspect your account has been accessed without your authorisation, contact us immediately at [email protected].
Your Data Rights
As a user of the zz661 Platform, you have the following rights in relation to your personal data. To exercise any of these rights, please contact us at [email protected]. We will respond to all requests within 30 days of receipt.
Right of Access
Request a copy of the personal data we hold about you, including the categories of data, the purposes for which it is processed, and any third parties it has been shared with.
Right to Rectification
Request correction of any inaccurate or incomplete personal data we hold about you. You may also update certain data directly via your account settings.
Right to Erasure
Request deletion of your personal data where it is no longer necessary for the purposes for which it was collected, subject to our legal retention obligations described in Section 7.
Right to Restrict Processing
Request that we limit how we use your personal data in certain circumstances — for example, while the accuracy of data you have contested is being verified.
Right to Data Portability
Receive a copy of the personal data you have provided to us in a structured, commonly used, machine-readable format, and request that it be transmitted to another service provider where technically feasible.
Right to Object
Object to the processing of your personal data where we rely on legitimate interests as our legal basis, including objecting to direct marketing communications at any time without giving a reason.
Right to Withdraw Consent
Where we process your data on the basis of your consent, you may withdraw that consent at any time. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.
Rights re: Automated Decisions
Request human review of any significant decision made about you solely by automated means — for example, account suspension triggered by automated fraud detection systems.
How to Submit a Request: Email us at [email protected] with the subject line "Data Rights Request" and specify which right you wish to exercise. We may need to verify your identity before processing your request. We will acknowledge receipt within 5 business days and provide a full response within 30 days. In complex cases we may extend this period by a further 30 days, in which case we will notify you promptly.
Children's Privacy
The zz661 Platform is strictly intended for adults aged 21 and above. We do not knowingly collect, process, or retain personal data from any individual under the age of 21. All prospective users are required to confirm their age during registration, and identity verification (KYC) procedures are in place to validate age declarations.
If we become aware that we have inadvertently collected personal data from a person under the age of 21, we will take immediate steps to delete that data from our systems, close the associated account, and reverse any transactions processed in connection with that account. If you believe that a minor has registered on the Platform or that we hold personal data relating to a person under 21, please notify us immediately at [email protected].
21+ Only: This platform is for adults aged 21 and above. We take our duty to prevent underage gambling seriously. Parents and guardians are encouraged to use parental control software to prevent minors from accessing online gambling platforms. For further guidance, visit our Responsible Gaming page.
Third-Party Links
The zz661 Platform may contain references to third-party services such as payment processors (bKash, Nagad, Rocket, Upay) and game technology providers (Pragmatic Play, Evolution Gaming, NetEnt, Microgaming, Spribe, Ezugi). Where you interact directly with a third-party service — for example, by completing a payment via the bKash app — your use of that service is governed by the third party's own privacy policy and terms of service, not by this Privacy Policy.
zz661 has no control over and accepts no responsibility for the privacy practices of third-party services. We encourage you to review the privacy policies of any third-party service you interact with in connection with your use of the Platform. Our inclusion of a reference to a third-party service does not constitute an endorsement of that service's privacy practices.
Policy Updates
zz661 reserves the right to update or modify this Privacy Policy at any time to reflect changes in our data practices, applicable law, or Platform features. When we make material changes to this policy, we will notify you by one or more of the following means:
- Posting a prominent notice on the Platform homepage or in your account dashboard.
- Sending an email notification to the address registered on your account.
- Updating the "Last Reviewed" date at the top of this Privacy Policy page.
We encourage you to review this Privacy Policy periodically. Your continued use of the Platform following the effective date of any updated version constitutes your acceptance of the revised policy. If you do not agree with any changes, you must discontinue use of the Platform and may request account closure by contacting [email protected].
Minor, non-material updates — such as typographical corrections or clarifications that do not change the substance of our data practices — may be made without prior notice, though the "Last Reviewed" date will always reflect the most recent revision.
