How does the 3999bd session replay tool work?

Use the 3999bd session replay tool to understand behavior; sensitive fields are masked, and login information is not captured directly.

Your session, device type, page views, and error summaries are visible. Personal payment information remains separately protected.

Sending a message to support limits tracking configuration. Some browser settings can also reduce cookies.

You can request data access, correction, restriction, and deletion; the 3999bd team responds within a specified time.

Effective date: August 2026, this privacy policy clearly states session replay, cookies, and data protection rules.

3999bd App Privacy Policy

Know in advance what information is collected when using the 3999bd App; many Dhaka users log in with bKash, Nagad, and Rocket, so the rules are written in simple language.

Your browsing, device, and session data are used only to keep the service running; the same security standards apply to the 3999bd Login and 3999bd Register pages.

How are sensitive fields hidden

Form fields are hidden during screen recording; passwords, phone numbers, and account IDs are masked, so they do not appear in the recording.

This is not only login; it also works in the 3999bd Download and 3999bd APK flow, Android phones require different permissions, but sensitive input stays hidden.

Which information is kept hidden

Passwords, OTPs, and payment inputs are masked; whether you are in Dhaka or Chattogram, the same rules apply to everyone.
