Bigwin never sends you unsolicited promotional messages. If you receive a message or email claiming to be from Bigwin that looks suspicious, please report it to our support team.

3. Data Sharing Policy

The most important aspect of Bigwin's Privacy Policy is who we share your data with. In short — we never sell your information to anyone.

However, your information may be shared in the following limited circumstances:

  • Payment processor: Minimal information is shared with bKash, Nagad, or Rocket solely to process transactions
  • Legal obligation: Information may be disclosed in response to a court order or a lawful request from a government authority
  • Fraud prevention: Cases involving money laundering or fraud may be reported to the relevant authorities
  • Technology Partners: Encrypted data may be shared with trusted technology providers solely for security verification purposes
Assurance: Before sharing any data, Bigwin ensures strict contractual protections are in place. Third parties are not permitted to use that data for their own purposes.

4. Data Retention & Retention Periods

Bigwin does not retain your data indefinitely. Each type of data has a defined retention period.

  • Active account data: retained for as long as the account remains active
  • After account closure: up to 5 years as required by law
  • Transaction records: 7 years (as required by financial regulations)
  • Cookie data: up to 12 months, then deleted automatically
  • Support chat history: deleted after 2 years

Once the retention period expires, data is securely deleted or rendered unreadable. This process is automated and requires no human intervention.

5. Cookies & Tracking Technologies

Bigwin uses cookies on its website to enhance your browsing experience. Cookies are small text files stored in your browser.

Cookies we use:

  • Essential cookies: For login sessions and security purposes — these cannot be disabled
  • Functional cookies: To remember your preferences, such as language settings
  • Analytics cookies: To understand which parts of the platform are used most

You can disable functional and analytics cookies at any time through your browser settings. However, disabling essential cookies may affect the platform's functionality.

Bigwin does not use any cross-site tracking or browser fingerprinting technology. When you visit other websites, Bigwin does not track you.

7. Payment Information Security

The security of financial transactions is Bigwin's top priority. The following safeguards are in place whenever you transact using your bKash, Nagad, or Rocket number:

  • Full payment details are not stored on Bigwin's servers
  • Every transaction is completed through an encrypted channel
  • Suspicious transactions are flagged automatically
  • Additional identity verification is required before large withdrawals

Bigwin will never ask for your payment PIN or OTP over a call or message. If you receive such a request, contact support immediately — it may be a fraud attempt.

8. Minor's privacy

Bigwin strictly refrains from serving anyone under the age of 18. We do not knowingly collect any personal information from minors.

If you suspect that a minor has created an account without a guardian's knowledge, the guardian may contact our support team directly. We will investigate the account, take the necessary steps, and delete any associated data.

Bigwin treats any complaint involving a minor with the utmost seriousness. Accounts are suspended immediately upon receiving such a report.

9. Changes to the Privacy Policy

Bigwin may update this Privacy Policy from time to time, as required by new laws, changes in technology, or improvements to our services.

Members will be notified of any significant changes via their registered mobile number or email. The date of the update will always be shown at the top of this page under "Last Updated".

Continued use of the platform after any changes will be considered acceptance of the updated Privacy Policy. We recommend visiting this page regularly.
