zk555 Privacy Policy — How We Handle Your Data

When you create an account on zk555, interact with customer support, or use any feature of the platform, you may provide us with personal information that includes, but is not limited to, the following:

• Full name as provided during registration.
• Mobile phone number used to register and verify the account (typically a Bangladeshi number used with bKash, Nagad, or Rocket).
• Date of birth, collected for age verification to confirm that you meet the 21+ requirement.
• Identity documents submitted during KYC verification (such as a National Identity Card, passport, or driving licence).

When you access and use zk555, certain technical information is collected automatically by our systems. This information is used to maintain platform security, optimise performance, and detect fraudulent or unusual activity. Automatically collected data includes:

• IP address and approximate geographic location (city or region level).
• Device type, operating system version, browser type and version, and screen resolution.
• Session activity data: pages visited, time spent on each page, game sessions initiated, bets placed, and navigation paths through the platform.
• Log files and error reports generated during your interaction with the platform.

When you make a deposit or withdrawal on zk555 using bKash, Nagad, Rocket, or Upay, transaction metadata is recorded. This includes the transaction reference number, the mobile wallet number (in masked form), the transaction amount, the date and time (Bangladesh Standard Time, UTC+6), and the transaction status. zk555 does not store your full mobile wallet PIN or any payment credential that could be used to initiate transactions on your behalf. Payment processing is handled via the respective wallet providers' secure APIs.

zk555 uses personal data collected from users for the following primary purposes, all of which are necessary for the lawful operation of an online gaming platform:

• Account creation, verification, and management: to register your account, verify your identity, maintain your account balance, and manage your profile settings.
• Transaction processing: to process deposits and withdrawals via bKash, Nagad, Rocket, and Upay, and to maintain accurate financial records of your account activity.
• Customer support: to respond to your queries, resolve disputes, investigate complaints, and provide technical assistance.
• Fraud prevention and platform security: to detect, investigate, and prevent fraudulent activity, money laundering, bonus abuse, multiple account registration, and any other activity that violates these Terms.
• Service improvement: to analyse aggregated usage patterns and improve the platform's design, game selection, payment experience, and customer support quality.

If you have opted in to receive promotional communications, zk555 may use your contact details (mobile number or email address) to send you information about bonuses, new game releases, seasonal promotions (such as Eid offers, Pohela Boishakh specials, or BPL season promotions), and other platform news. You may opt out of marketing communications at any time by contacting [email protected]. Opting out of marketing will not affect transactional notifications that are necessary for the operation of your account (such as deposit confirmations and withdrawal status updates).

zk555 does not sell, rent, or trade your personal information to third parties for their own marketing purposes. We may share your personal data only in the following limited circumstances:

• Service providers: with trusted third-party service providers who process data on our behalf under strict confidentiality obligations, including payment processors (bKash, Nagad, Rocket, Upay), game technology providers (such as Evolution Gaming, Pragmatic Play, Spribe), and platform infrastructure providers.
• Legal and regulatory compliance: where required by applicable law, regulation, court order, or lawful government request, including requests from financial intelligence or anti-money-laundering authorities.
• Fraud prevention agencies: to the extent necessary to prevent, detect, or investigate fraud, money laundering, or other illegal activity affecting zk555 or its users.
• Business transfers: in the event of a merger, acquisition, or sale of substantially all of zk555's assets, your data may be transferred to the successor entity as part of that transaction. You will be notified of any such transfer.

For the avoidance of doubt, zk555 does not and will not sell, license, or otherwise make available your personal data to advertisers, data brokers, marketing agencies, or any other commercial third party for that party's own independent use. This commitment applies regardless of any change of ownership or control of zk555, subject to the business transfer notice obligations stated above.

zk555 takes particular care with payment-related data. When you make a deposit via bKash, Nagad, Rocket, or Upay, you are redirected to or interact directly with that payment provider's interface. zk555 does not receive or store your full mobile banking PIN, OTP codes, or equivalent authentication credentials. What we do receive is a transaction confirmation from the payment provider confirming that a payment of a specified amount has been successfully made from a specified (masked) account number.

For withdrawal processing, zk555 records the mobile wallet number to which funds are to be sent. This number is stored in masked form in our systems (for example, a Nagad number might be stored as 017XXXXX890) and is only unmasked by authorised personnel during the withdrawal processing workflow. All payment records are retained for a minimum of five years in accordance with applicable financial record-keeping obligations.

zk555 uses cookies and similar tracking technologies (such as local storage and session tokens) to operate the platform, maintain your logged-in session, and improve your experience. Cookies are small text files placed on your device when you access our website. The types of cookies we use include:

• Essential cookies: required for the platform to function correctly, including session authentication tokens, language preference storage, and security tokens. These cannot be disabled without breaking core functionality.
• Analytics cookies: used to collect aggregated and anonymised data about how users navigate the platform, which pages are most visited, and how long users spend on each section. This data helps us improve the platform design and content.
• Preference cookies: used to remember your settings and preferences such as your chosen display language, so that these are applied automatically on your next visit.

Most modern browsers allow you to control cookies through their settings. You may block or delete cookies, but doing so may impair the functionality of the zk555 platform, including your ability to remain logged in. zk555 does not use cookies to track your activity across third-party websites.

zk555 retains personal data for as long as is necessary to fulfil the purposes for which it was collected, including for the purposes of satisfying any legal, accounting, or regulatory reporting requirements. For active accounts, personal data is retained for the duration of your account's existence plus a minimum of five years following account closure, in line with standard financial services record-keeping practice.

Where personal data is no longer required for the purposes for which it was collected and no legal retention obligation applies, zk555 will securely delete or anonymise that data. Transaction records are retained for a minimum of five years from the date of the transaction. KYC documents submitted by users are retained for the duration of the account plus five years, in accordance with applicable anti-money-laundering regulations.

As a user of zk555, you have the following rights with respect to your personal data. To exercise any of these rights, contact our support team at [email protected]. We will respond to all valid requests within a reasonable timeframe, typically within 30 days of receipt:

• Right of access: you may request a copy of the personal data we hold about you, including a description of how it is used and with whom it has been shared.
• Right of rectification: if any personal data we hold about you is inaccurate or incomplete, you may request that we correct or complete it.
• Right of erasure: you may request deletion of your personal data where it is no longer necessary for the purposes for which it was collected, subject to any overriding legal retention obligations.
• Right to restrict processing: you may request that we limit the ways in which we process your personal data in certain circumstances, for example where you contest the accuracy of the data.
• Right to object: you may object to our processing of your personal data for direct marketing purposes at any time, and we will cease such processing upon receipt of a valid objection.

zk555 will make every reasonable effort to respond to and fulfil rights requests promptly. In some cases, we may need to verify your identity before processing a request, to ensure that we do not disclose personal data to an unauthorised person.

zk555 implements industry-standard technical and organisational security measures to protect your personal data against unauthorised access, accidental loss, destruction, or disclosure. These measures include 256-bit SSL/TLS encryption for all data transmitted between your device and our servers, encrypted storage of sensitive data at rest, access controls ensuring that personal data is accessible only to authorised personnel who require it for their role, and regular security audits of our platform infrastructure.

While zk555 takes all reasonable steps to protect your personal data, no internet-based platform can guarantee absolute security. You also play an important role in keeping your data safe: keep your account password confidential, log out of your account when not in use, and notify us immediately at [email protected] if you suspect any unauthorised access to your account.

zk555 is strictly an adults-only platform. We do not knowingly collect, use, or retain personal data from any individual under the age of 21. If we discover or are informed that a person under 21 has registered an account or provided us with personal data, we will immediately suspend that account, void any associated transactions, and permanently delete the personal data of that individual. If you believe that a minor has created an account on zk555, please notify us immediately at [email protected].

zk555 reserves the right to update or amend this Privacy Policy at any time. When we make material changes, we will update the "Last updated" date at the top of this page and, where the changes are significant, notify registered users via their registered contact details. Your continued use of zk555 following the effective date of any updated Privacy Policy constitutes your acceptance of the revised policy. We encourage you to review this page periodically to stay informed about how we protect your information. The current version of this policy is always available at zk555.ws/privacy-policy.
