3999bt only collects information that is strictly necessary for account management, payment processing, and legal compliance. No unnecessary data is requested.
Your password, payment details, and identity documents are protected with 256-bit AES encryption — the same technology used by banks and government institutions.

This policy clearly explains how your data is used. No data is used for hidden purposes — that is 3999bt's firm commitment.

3999bt (website: 3999bt.click and associated mobile app) places the highest importance on the privacy of its users' personal data. This Privacy Policy applies to all registered and unregistered users in Bangladesh — meaning it covers you even if you are simply browsing the website.
By using any of 3999bt's services, you consent to the data processing practices described in this Privacy Policy. This policy has been written in Bengali so that every Bangladeshi user can fully understand it in their own language.
