wien believes that a user's personal information is an extremely valuable asset. We take the utmost care in storing, using, and keeping this information secure. You can learn more about us and our operations on our about us page.

This policy may be updated from time to time. Any changes will be published on the website and, where applicable, communicated to your registered email. The date of the most recent change will be noted at the bottom of this page.

All third parties who receive information are bound by a confidentiality agreement similar to this policy and are required to use the information only for the specified purpose.

Cookies and similar technologies are used on the wien website and app. These are small text files stored on your device that help improve the user experience.

5.1 Essential Cookies

These cookies are essential for running the platform. They include maintaining login sessions, verifying security tokens, and keeping the payment flow active. Disabling them will disrupt the core functions of the site.

5.2 Functional Cookies

These cookies are used to remember your preferred language, game settings, and display preferences. Without them, settings will need to be re-entered at the start of each new session.

5.3 Analytical Cookies

These cookies are used to understand which pages are viewed most, where technical issues occur, and which features are most popular. This information helps improve the quality of the service.

You can control or disable cookies from your browser settings. However, disabling essential cookies may cause some services to not work properly.

wien has put in place industry-standard technical and administrative measures to protect user data. These layers of protection work together to prevent unauthorised access or data leaks.

If a data breach occurs, affected users will be notified in a timely manner and necessary steps will be taken to minimise damage.

wien retains user information only for as long as necessary. All information is stored securely while an account is active. Even after an account is closed or deleted, some information must be kept for a specified period due to legal obligations.

• KYC verification documents: minimum 5 years from the date of account closure
• Financial transaction records: for the period determined by applicable regulations
• Cookie data: upon end of session or after the set expiry period
• Customer support communication records: 2 years from the date the issue was resolved

After the set period, data is securely deleted or converted in a way that prevents identification of individuals.

As a user of the wien platform, you have the following rights over your own information:

8.1 Right to Access Information

You can view the information stored in your account at any time. Contact the support team if you would like to know what information we hold about you.

8.2 Right to Correct Information

If any information is incorrect or incomplete, you can request that it be corrected. After KYC verification, changes to certain key information may require re-verification.

8.3 Right to Close Account and Delete Information

You may close your account if you wish. However, some information must be retained for a specified period due to legal obligations, as noted in section 7 of this policy.

8.4 Right to Opt Out of Marketing Communications

If you do not wish to receive promotional messages, you can turn off marketing communications from your account settings or through the support team.

Rights related to responsible gaming and self-exclusion options are discussed in detail in our responsible gaming guidelines.

All wien services are for persons aged 21 or above only. If any person under 21 creates an account or uses the service, their account will be immediately closed upon verification and any deposited funds will be handled in accordance with applicable rules.

We do not intentionally collect any information from persons under 18. If it becomes known that information from a minor has been collected, it will be deleted immediately.

For operational purposes, some data may be stored or processed on servers located outside Bangladesh. In such cases, appropriate contractual safeguards are in place to maintain data protection standards.

Service providers who use overseas infrastructure are also contractually bound to follow the same privacy standards as this policy.

This privacy policy may be updated from time to time based on changes to services, introduction of new technologies, or legal requirements. For significant changes, you will be notified by registered email or through the platform.

Continued use of the platform after changes are made will be considered acceptance of the new policy. It is therefore recommended that you check this page regularly.
