BD333 App Privacy Policy

Who this BD333 App policy serves

This page is for BD333 App users who want clear answers about their data, explaining the policy since 2018 on collected service usage, anonymization, and limited sharing.

You will be able to view some browsing data even without logging in; the policy is written to understand local practices like bKash, Nagad, and Rocket, so reading is easier for Dhaka mobile users.

• Only necessary information is collected
• Personal data is anonymized
• If you want extra cookies, you can turn them off.

How anonymization is done

Anyone's name, phone number, or account ID are not directly used in research; the system separates them and replaces them with hashes, groups, and random codes, so individuals cannot be identified.

The process is done step by step: first the identifying fields are removed, then usage patterns are combined, and finally the report shows only aggregated results.

What data is excluded

• Login identifiers
• Device's personal name
• Specific transaction ID

Scope and use of research

BD333 App research team sees which screens are opened most, on which devices the app runs fastest, and where load times increase, making it easier to improve usage in places like Dhaka, Chattogram, and Khulna.

Here, personal accounts, financial data, or login passwords are not captured in research; only aggregated statistics like 308,327 active users are reported, and that is anonymized.

• App performance is viewed
• Usage trends are understood
• Personal profile stays separate

Sharing information with academics

Sometimes anonymous datasets are shared with universities or research institutions; before sharing, the team checks whether the dataset contains aggregated information such as 786+ content or usage patterns, and whether identities are separated

No data leaves without a contract; partners must follow the same rules, so they can only read trends, not anyone's identity

• Sharing is limited and documented
• Only anonymized data goes
• User identity remains separate

Cookies and local storage

Cookies maintain the session, so you don't have to log in again; these small files remember language preference, screen settings, and pages you've previously seen

If you disable cookies in browser settings, some features may be reduced, but the main page will not have issues.

• Keeps session active
• Remembers preferences
• Experimental cookies are separate

Opt-out and user rights

If you want to remove your name from research-based use, you can contact support; login to your account from the BD333 Login page to change settings, and you can also request record corrections.

Requests are typically answered within 2 business days; many Dhaka users send requests at night, so the system keeps that in mind when submitting messages.

• You can request data copies
• You can correct incorrect
• You can opt out of research use

Policy contact

If any part seems unclear, contact directly from the BD333 Contact page; sending a message will get a separate reply about policy, cookies, or data protection.

When discussing privacy, do not provide unnecessary information; if needed, provide screenshots or reference numbers, and the team will address it.
