The security of your personal information is our highest priority. Read this policy to learn exactly how we collect, use, and protect your data.

Last Updated: January 1, 2026 Language: Bengali SSL secured

Your privacy is a trust we hold sacred. 39ko never sells your personal information to third parties or shares it without your consent.

1 Introduction & Scope

39ko (website: https://39ko.org) is an online betting and gaming platform built specifically to serve users in Bangladesh. This Privacy Policy applies to all members who use our platform.

We believe data security is not just a technical matter — it is an ethical commitment. By creating an account or using our services at 39ko, you are considered to have consented to this Privacy Policy.

This policy covers three key areas: how your information is collected, what it is used for, and how it is kept secure. Our support team is always available for any questions.

This policy may be updated from time to time. Any changes will be communicated via your registered email or a notice on the site. The latest version will always be available on this page.
