Who is this privacy policy for

This 39bd privacy policy is written for Bangladesh users using the 39bd App from Dhaka, Chattogram and other cities; how their data is handled is explained here.

Effective date: August 2026; we kept the language simple so you can quickly understand what data is needed.

What data is collected and why

We usually collect name, email, device information and usage logs to help the 39bd App run properly.

Many Dhaka users log in on mobile data, so light logging is kept to avoid speed loss and keep security intact.

Where caution is needed

Keep passwords, OTP and recovery information always to yourself; sharing with others weakens security.

After downloading 39bd, review the permissions list; if any unnecessary permissions are granted, disable them immediately.

How security works

Here encryption, access control and log monitoring are used; this makes it easier to detect unusual behavior.

One important note: the system aims to maintain 99.8% uptime, so reliability and security are considered together.

New phone, new browser or unusual session detected; even a small signal triggers an alert.

Data protection

Sensitive information is kept separately; this reduces account risk.

Data retention period

Data is kept only for as long as necessary for an active account to operate the service.

If the account is closed, some records may remain for a few more days due to legal and security reasons; this time limit may vary by usage.

Your control

If you see incorrect information you can request corrections; to delete any records, write to our contact page.

If needed, we review previous requests, logs and support history.

Compliance and cross-border data processing

Data may sometimes move to servers elsewhere; when this happens, security levels are maintained in line with compliance rules.

We keep the same standard so that data in transit remains secure; this is important for users in 29 countries.

What this means for local users

During top-ups with Nagad or Rocket, only necessary transaction data remains; this supports auditing.

bKash users also receive the same security path; no unnecessary data is stored outside transactions.

Protection of minors

This service is for adult users; if age rules are violated, account verification can become difficult.

If you think a minor has used it by mistake, contact us quickly and we will take necessary steps.
