Everything you need to know about how your personal data is collected, used, and kept safe — explained in plain English.
When you open an account, place a bet, or simply browse the Bigwim website, certain data is generated as a natural part of that activity. You have the right to know how we use that data, where it is stored, and for how long.
This Privacy Policy aims to answer those questions honestly and plainly. We have nothing to hide behind legal jargon. Bigwim believes that transparency is the foundation of genuine trust.
This policy applies to Bigwim's website (bigwim.im), mobile platform, and all our services. By using our services, you agree to this policy.
Key Takeaways: Your data belongs to you. Bigwim uses it solely to provide you with services — never to sell or rent it.
Bigwim collects two types of data — what you provide directly, and what is automatically generated through your use of the platform.
Information You Provide Directly:
Automatically Generated Information:
| Data Type | Why It's Collected | Retention Period |
|---|---|---|
| IP Address | Security & Fraud Prevention | 90 Days |
| Device Information | Platform Optimisation | Until logout |
| Browsing Logs | Error Detection | 30 days |
| Betting History | Account Records & Dispute Resolution | 5 Years |
| Payment Logs | Financial Records & Audits | 7 years |
| Cookie Data | Improving User Experience | Based on Cookie Expiry |
We never store your password, full payment card number, or mobile banking PIN.
Bigwim uses your data only for legitimate purposes. Each use is clearly outlined below:
Important: Bigwim does not — and will never — sell your data to any advertising or marketing company. That is our commitment.
For analytical purposes, we use aggregated, anonymized data in which no individual can be identified.
Bigwim protects your data using industry-leading technology. Security isn't just a feature for us — it's the foundation of everything we do.
Our Security Framework:
Data Retention Period: Even after account closure, certain data must be retained for a specified period due to legal obligations. Payment records are kept for 7 years and betting history for 5 years.
In the event of a data breach: In the event of a security breach, affected users will be notified via SMS/email within 72 hours.
Bigwim does not sell your data. In limited circumstances, a minimal amount of information may be shared with necessary third parties:
| Third Parties | What Data | Why |
|---|---|---|
| Mobile Banking (bKash/Nagad) | Transaction Information | Payment Processing |
| Identity Verification Service | NID Information | KYC Verification |
| Cloud Storage Provider | Encrypted Data | Server Management |
| Government / Law Enforcement Agencies | Required Information | Legal Compliance |
| Fraud Detection Service | Transaction Patterns | Fraud Prevention |
Every third-party provider is bound by a strict confidentiality agreement with Bigwim. They receive only the specific data needed for their designated function — any use beyond that is strictly prohibited.
Legal Requirements: We are legally required to disclose information when ordered by a court or upon a valid request from a government authority. Where possible, you will be notified in advance.
Bigwim uses cookies on its website. Cookies are small text files stored in your browser that help improve your experience on the site.
Cookies we use:
You can disable or delete cookies at any time from your browser settings. However, some features may not work properly if you do.
You have full control over your data on Bigwim. Your rights are detailed below:
To exercise any of these rights, contact our support team. Requests are typically processed within 30 days.
Bigwim strictly does not collect data from or provide services to anyone under the age of 18. Age is verified at registration, and KYC verification may be requested if there is any doubt.
If a minor under the age of 18 is found to have created an account for any reason, the account will be immediately closed and all associated data deleted upon discovery.
To Parents: If your child has accidentally accessed Bigwim, please notify us immediately. We will delete all associated data and make every effort to reverse any transactions that may have occurred.
Bigwim may send you promotional offers, bonus updates, and game-related information via SMS or email — but only with your consent.
You can opt out of marketing communications at any time:
Please note: opting out will stop marketing messages, but transactional SMS — such as withdrawal confirmations and security alerts — will continue to be sent.
Bigwim may update this Privacy Policy from time to time. This may be necessary due to regulatory changes, new technology, or updates to our services.
For significant changes:
You can check the "Last Updated" date at the top of the page to see when changes were last made. Continued use of the service following any update constitutes acceptance of the revised policy.
