Data Protection & Privacy
When you use Koww, here is exactly where your data goes, how it is used, and what rights you have — explained in plain English, no legal jargon.
By using Koww, you are considered to have read and agreed to this Privacy Policy.
Core commitments
Before diving into the full Privacy Policy, here are six key things you should know.
All your data is protected with 256-bit SSL encryption. From your browser to our servers, no one can intercept or read your information in transit.
Koww never sells your personal information to advertisers, marketing agencies, or any third party. This is a commitment that will never change.
Koww only collects information that is genuinely necessary to provide its services. No unnecessary data is requested or stored.
You can request to view, correct, or delete your data at any time. When you close your account, your data is securely deleted.
Koww's data is stored in top-tier certified data centers across the Asia-Pacific region, with 24/7 security monitoring in place.
If any unusual activity is detected on your account, you'll be alerted immediately via mobile or email. Security is always active.
This Privacy Policy applies to the Koww (koww.best) website and mobile application. By using any Koww service, you are automatically considered to have accepted this policy.
Koww takes your privacy seriously. We believe every user should have full control over their own data — which is why this policy is written in plain, straightforward language, so there is no confusion about what is happening.
Summary: Koww keeps your data secure, never sells it, and uses it solely to improve your experience.
This policy was last updated in January 2026. If changes are made, the date at the top of the page will be updated, and significant changes will be communicated to your registered mobile number.
Koww collects information in three ways — what you provide directly, what is automatically generated as you use the platform, and what is needed to process payments.
What you provide directly:
Automatically collected information:
| Data type | Reason for collection | Required? |
|---|---|---|

| Date of birth | Age verification (18+) | Yes |
| Payment Information | Deposit & Withdrawal Process | Yes |
| NID / Passport | Identity Verification (KYC) | When necessary |
| Device & browser information | Security & technical support | Automatic |
Koww uses the data it collects exclusively for the purposes listed below. It is never used for anything else.
Koww never uses your betting history or financial information for advertising purposes, and does not share data with third parties for profiling or targeted advertising.
Koww does not sell your data. However, in certain circumstances, limited information may need to be shared with trusted partners.
Never shared: Advertising agencies, data brokers, or any third party for commercial purposes.
All third parties are required to sign strict data protection agreements. They cannot use your information for any purpose beyond what Koww has explicitly authorized.
Koww uses cookies and similar technologies. Cookies are small data files stored in your browser that help improve your experience.
Cookie types:
You can manage cookies through your browser settings. However, disabling essential cookies may cause issues with login or payments. Koww does not use any third-party tracking or advertising cookies.
Koww retains your data only for as long as necessary. It is not kept beyond what is required by law.
Upon receiving an account closure request, Koww will begin the process of deleting your personal data within a maximum of 30 days.
Koww believes every user should have full control over their own data. The rights listed below are yours to exercise at any time.
To exercise any of these rights, contact Koww Support by email at support@koww.best or via live chat. Requests are typically responded to within 7 business days of receipt.
Koww's services are strictly for users aged 18 and above. Koww does not knowingly collect any information from anyone under the age of 18.
If any minor's data is collected accidentally and we are notified, Koww will remove that data immediately and close the associated account.
If you believe a minor is using Koww, please notify us immediately.
Koww may update this Privacy Policy from time to time. When changes are made, the revised date will be updated at the top of the page.
For significant changes — especially those that materially affect how your data is used — you will be notified in advance via SMS to your registered mobile number or by email. Continued use of Koww after changes take effect will be considered acceptance of the updated policy.

Full Details
Many people in Bangladesh have a natural concern when using online platforms — "Where is my data going?" That's a fair question, and Koww believes it's our responsibility to answer it honestly.
When Koww launched in 2018, data privacy was built into the foundation of our business from day one. A significant portion of our tech team is dedicated exclusively to security and privacy, and we conduct regular third-party security audits.
All data stored on Koww's servers is encrypted at rest — meaning it cannot be read even with direct server access. Sensitive payment details such as full mobile banking numbers are never stored on Koww's servers; transactions are processed directly through the payment gateway.
Your IP address is collected for two purposes only — security (to alert you if a login attempt is made from a suspicious location) and technical troubleshooting. Your IP is never used to build a profile about you or for advertising.
Your mobile number is used for account verification, transaction OTPs, and security alerts. You can opt out of promotional SMS at any time — the option is available in your account settings, or simply contact support. However, critical security messages (such as login OTPs and suspicious activity alerts) cannot be turned off, as they exist to protect you.
Installing the Koww app will prompt you to grant certain permissions. Each permission serves a specific purpose — the camera is used solely for scanning KYC documents, and notifications are for important updates. Optional permissions help improve your app experience, but the app works fine without them.
In the event of a data breach, Koww will notify affected users as quickly as possible and provide guidance on protective measures. Transparency and swift action are central to how Koww responds.
Simply put — sharing your data with Koww is an act of trust. Protecting that trust is not just our legal obligation; it is our ethical one. It is this commitment that has earned the confidence of millions of users in Bangladesh.
