## What is B4P?

B4People: RUPP Citizen Science Initiative

B4People is an academic research application developed by the Royal University of Phnom Penh (RUPP) under the Build4People project. The app serves as a digital gateway for students and citizens to participate in urban environmental monitoring.

Complete a short survey regarding your perception of the local environment.
Submit your data anonymously to the RUPP research database.

Research Integrity & Privacy:
 - No Account Required: To ensure participant anonymity, no login or registration is needed.
 - Non-Commercial: This is a strictly academic tool; no data is shared with third-party advertisers.
