4. Legal Basis for Processing
windb processes your personal data on the following legal bases, depending on the nature of the processing activity involved.

- Legitimate Interests:windb processes technical and device data on the basis of its legitimate interests in operating a secure, reliable, and fraud-resistant platform. windb also uses aggregated, anonymised analytics data on the basis of legitimate interests in improving the platform experience for all Bangladesh players.
- Consent:Where windb sends promotional communications (such as bonus offer notifications or seasonal promotions aligned with events like Eid or BPL), this is done on the basis of your consent, given during registration or subsequently through your account communication preferences. You may withdraw this consent at any time by updating your preferences or contacting support.
5. Sharing Your Information
windb does not sell, rent, or trade your personal data to third parties for their own marketing or commercial purposes. windb may share your personal data with third parties only in the limited circumstances described in this section.
- Payment Processors:windb shares the minimum financial data necessary with payment processors — including bKash, Nagad, Rocket, Upay, and card payment gateways — solely for the purpose of processing your deposits and withdrawals. These processors are bound by their own data protection obligations and applicable financial regulations.
- Game Providers:windb's game suppliers — including Evolution Gaming, Pragmatic Play, Spribe, Ezugi, and Microgaming — may receive anonymised session and gameplay data for the purpose of delivering their games and ensuring technical integrity. These providers do not receive your identity or contact data.
- Legal and Regulatory Authorities:windb may disclose personal data to law enforcement agencies, financial intelligence units, or other regulatory authorities where required by applicable law, court order, or where windb has a good-faith belief that disclosure is necessary to prevent fraud, money laundering, or other criminal activity.
- Service Providers:windb may engage trusted third-party service providers — such as customer support platform operators, email delivery services, or analytics tools — who process personal data on windb's behalf under strict data processing agreements. These providers may only use your data for the specific purpose for which they were engaged and may not use it for their own purposes.
6. Cookies and Tracking Technologies
windb uses cookies and similar tracking technologies to operate the platform, maintain your login session, remember your preferences, and gather anonymised analytical data about how players use the site. By using the windb platform, you consent to the use of cookies as described in this section.
- Essential Cookies:These cookies are strictly necessary for the windb platform to function. They enable core functionality such as maintaining your login session, processing deposits and withdrawals, keeping your game in progress during a session, and delivering security features. Essential cookies cannot be disabled without preventing the platform from working correctly.
- Analytical Cookies:windb uses anonymised analytical cookies to understand how players navigate and use the platform — including which game categories are most popular, which pages are visited most frequently, and where players encounter difficulties. This data is used in aggregate form only and cannot be linked back to any individual player.
- Preference Cookies:These cookies remember your platform preferences such as your chosen language setting, notification preferences, and display settings, so you do not need to re-enter them each time you visit windb. Preference cookies improve the continuity and personalisation of your experience.
You can control non-essential cookies through your mobile browser settings. Please note that disabling certain cookies may affect the functionality of the windb platform. windb does not use cookies for any advertising or retargeting purposes on third-party websites.
7. Data Security
windb takes the security of your personal data seriously and implements appropriate technical and organisational measures to protect it against unauthorised access, disclosure, alteration, or destruction. These measures include SSL (Secure Sockets Layer) encryption for all data transmitted between your device and the windb platform, encrypted storage of sensitive account data, access controls that restrict personal data access to authorised windb personnel on a need-to-know basis, regular internal security reviews, and secure disposal procedures for data that is no longer required.
While windb applies robust security practices, no online platform can guarantee absolute security against all possible threats. In the event of a personal data breach that is likely to result in a risk to your rights or interests, windb will take prompt steps to contain the breach and will notify affected players using their registered contact details as soon as reasonably practicable.
8. Data Retention
windb retains your 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, regulatory, accounting, or reporting requirements. The retention period for different categories of personal data varies depending on the nature of the data and the obligation that requires its retention.
As a general guideline: account and identity data is retained for a minimum of five (5) years following account closure to comply with AML and KYC record-keeping obligations; financial transaction data is retained for a minimum of five (5) years; gaming activity data is retained for the duration of your account and for up to two (2) years after account closure; technical and device log data is retained for up to twelve (12) months. When personal data is no longer required, windb securely deletes or anonymises it.

- Right to Withdraw Consent:Where windb processes your personal data on the basis of your consent (for example, for promotional communications), you have the right to withdraw that consent at any time.

10. Children's Privacy
The windb platform is strictly intended for adults aged 21 years and above. windb does not knowingly collect personal data from individuals under the age of 21. If windb becomes aware that personal data has been collected from a person under 21, it will take immediate steps to delete that data and close the associated account.

11. Third-Party Links and Services
The windb platform integrates third-party game content from certified providers including Evolution Gaming, Pragmatic Play, Spribe, Ezugi, and Microgaming. While windb selects these providers carefully, each provider operates under its own privacy policy and data practices. windb is not responsible for the privacy practices of third-party game providers, payment processors, or any other third-party services accessible in connection with the windb platform. Players are encouraged to review the privacy policies of any third-party services they interact with.
12. Bangladesh-Specific Provisions
windb's primary player base is located in Bangladesh. All personal data collected from Bangladesh-based players is handled with Bangladesh players' rights and reasonable expectations in mind. Payment data associated with Bangladeshi mobile financial services — including bKash, Nagad, Rocket, and Upay — is processed in accordance with the relevant service providers' own terms and privacy standards, which are independent of windb's internal data practices.
windb recognises the importance of data privacy to Bangladesh players and is committed to ensuring that personal data is handled transparently, securely, and only for the purposes described in this Policy. Where windb's data practices are subject to specific requirements applicable to Bangladesh-based online services, windb will apply those requirements in addition to the general standards set out in this Policy.
