If you contact our support team via live chat or email at [email protected], we retain records of those communications including the content of your messages, the date and time of contact, and the resolution outcome.

3 Cookies and Tracking Technologies

zz661 uses cookies and similar tracking technologies on zz661.app to ensure the platform functions correctly, to maintain your logged-in session, to remember your preferences, and to gather anonymised analytics data about how Players use the site. This section explains what cookies we use and how you can manage them.

3.1 What Are Cookies?

Cookies are small text files placed on your device by a website when you visit it. They are widely used across the internet to make websites function efficiently, to remember user preferences, and to provide website operators with analytical information. Cookies do not contain executable code and cannot carry viruses or malware.

3.2 Types of Cookies Used by zz661

• Strictly Necessary Cookies: These cookies are essential for the zz661 platform to operate. They maintain your login session, preserve your Account security tokens, and enable core functions such as deposits and game loading. These cookies cannot be disabled without breaking the platform's core functionality.
• Functional Cookies: These cookies remember your preferences and settings, such as your preferred language (English), display preferences, and last-visited game category. Disabling these cookies means you may need to re-enter your preferences each time you visit.
• Analytics Cookies: These cookies collect anonymised data about how Players navigate zz661.app, including which pages are visited most frequently, how long sessions last, and where Players encounter difficulties. This data helps us improve the platform. The analytics data collected is aggregated and does not identify individual Players.
• Security Cookies: These cookies support our fraud detection systems by helping us identify unusual or suspicious access patterns, including login attempts from unrecognised devices or IP addresses that deviate significantly from your normal usage pattern.

3.3 Managing Your Cookie Preferences

You can manage or disable non-essential cookies through your browser settings. Most modern browsers allow you to view, delete, and block cookies on a per-site basis. Please note that disabling strictly necessary cookies will prevent you from logging into your zz661 Account and accessing the platform. Instructions for managing cookies in commonly used browsers are available in each browser's help documentation. Continuing to use zz661.app without changing your browser's cookie settings indicates your acceptance of our use of cookies as described in this section.

4 Sharing Your Data with Third Parties

zz661 shares your personal data only in the limited circumstances described below. In every case, data sharing is governed by written data processing agreements that require third parties to protect your data to the same standard applied by zz661 itself.

• Payment Processing Partners: When you make a deposit or request a withdrawal, your mobile financial service account number and transaction amount are shared with the relevant payment provider (bKash, Nagad, Rocket, or Upay) to the extent necessary to process the transaction. These providers operate under their own privacy policies and are regulated financial entities in Bangladesh.
• Game Software Providers: Your Account identifier and session data may be shared with our game software providers (such as Pragmatic Play, Evolution Gaming, Spribe, NetEnt, Microgaming, and Ezugi) to enable game sessions to function correctly, to facilitate dispute resolution in the event of a game error, and to support the RNG certification process. These providers do not receive your full identity data and are bound by strict data processing agreements.
• Identity Verification Service Providers: We may use specialist third-party KYC verification services to authenticate the identity documents you submit. These providers process your document data solely for the purpose of verification and are not permitted to retain or use your data for any other purpose.
• IT Infrastructure Providers: zz661 operates on third-party cloud and server infrastructure. Our infrastructure providers may have limited, incidental access to data stored on their systems. All such providers are bound by confidentiality obligations and are prohibited from accessing Player data for any purpose other than providing infrastructure services to zz661.
• Law Enforcement and Regulatory Authorities: zz661 will disclose personal data to law enforcement agencies, financial intelligence units, or other competent authorities when legally required to do so, including in response to court orders, lawful subpoenas, and anti-money laundering investigations. We will notify affected Players of such disclosures wherever we are legally permitted to do so.
• Business Transfers: In the event that zz661 undergoes a merger, acquisition, or sale of all or a substantial part of its assets, your personal data may be transferred to the acquiring entity as part of that transaction. You will be notified of any such transfer and the privacy implications before it takes effect.

zz661 does not share your personal data with any third party for that party's own marketing, advertising, or commercial purposes. We do not sell personal data. We do not share data with social media platforms, data brokers, or any entity that is not directly involved in delivering the zz661 service to you.

5 Data Retention and Storage

zz661 retains your personal data for as long as is necessary to fulfil the purposes for which it was collected, to comply with applicable legal retention obligations, and to resolve any disputes or enforce our agreements. The retention periods applicable to different categories of data are summarised below.

• Account and Identity Data: Retained for the duration of your active Account relationship with zz661, and for a minimum of five years following Account closure. This retention period reflects standard financial recordkeeping obligations applicable to online payment platforms operating in Bangladesh.
• KYC Documents: Retained for a minimum of five years from the date of submission or from the date of Account closure, whichever is later. This is required to support anti-money laundering compliance obligations.
• Financial Transaction Data: Retained for a minimum of seven years from the date of each transaction, in line with standard financial record retention requirements.
• Gameplay and Betting Activity Data: Retained for three years from the date of each session, or longer where the data is relevant to an outstanding dispute or investigation.
• Customer Support Communications: Retained for two years from the date of last contact, unless the communication relates to an ongoing dispute, in which case it is retained until that dispute is fully resolved.
• Technical and Device Data (Log Files): Retained for a maximum of 12 months from collection, after which they are permanently deleted or fully anonymised.

Upon expiry of the applicable retention period, personal data is securely and permanently deleted from zz661's systems or rendered irreversibly anonymous. Players may request confirmation of the specific retention period applicable to their data by contacting [email protected].

6 Your Privacy Rights

As a Player on the zz661 platform, you hold a number of rights with respect to your personal data. These rights are set out below. To exercise any of these rights, please submit a written request to [email protected]. zz661 will respond to all valid data rights requests within 30 calendar days of receipt.

Please note that certain rights are subject to limitations where zz661 has overriding legal obligations — for example, we cannot delete financial transaction records that we are legally required to retain for anti-money laundering compliance purposes. Where a rights request cannot be fulfilled in full, we will explain the reason in writing.

To exercise any of the rights described above, please email [email protected] with the subject line "Privacy Rights Request" and include your Account username and a description of the specific right you wish to exercise. We may need to verify your identity before processing the request.

7 How We Secure Your Data

The security of your personal data is a core operational priority at zz661. We implement a layered set of technical and organisational security measures designed to protect your data against unauthorised access, accidental loss, disclosure, alteration, or destruction. These measures include but are not limited to the following:

• SSL/TLS Encryption: All data transmitted between your device and zz661.app is encrypted using industry-standard SSL/TLS protocols. This ensures that your login credentials, payment details, and personal information cannot be intercepted during transit.
• Password Hashing: Your Account password is never stored in plain text. It is processed through a one-way cryptographic hashing algorithm before storage, meaning that even zz661 staff cannot view your actual password.
• Access Controls: Access to Player personal data within zz661's internal systems is restricted on a strict need-to-know basis. Only staff with a legitimate operational reason to access specific data categories are granted that access, and all access events are logged for audit purposes.
• Two-Factor Verification for High-Value Withdrawals: Withdrawal requests above certain thresholds trigger additional identity verification steps to ensure that no unauthorised party can remove funds from your Account.
• Fraud Detection Systems: zz661 operates automated monitoring systems that analyse login patterns, transaction behaviour, and gameplay data in real time to detect and flag unusual activity that may indicate Account compromise or fraudulent use.
• Secure Document Storage: KYC documents submitted by Players are stored in an encrypted document management system with restricted access. Documents are not stored on publicly accessible servers.
• Regular Security Reviews: zz661 conducts periodic internal security reviews of its data handling practices, access controls, and technical infrastructure to identify and address potential vulnerabilities before they can be exploited.

Despite the robust security measures described above, no online platform can guarantee absolute security against all possible threats. Players are strongly advised to choose a strong, unique password for their zz661 Account, to never share their login credentials with any third party, and to contact [email protected] immediately if they suspect that their Account has been accessed without their authorisation.
