DataPost

Help measure the impact of offline education. Carry usage data from RACHEL hotspots back to the cloud and turn every visit into insight.

Help measure the impact of offline education.

DataPost turns your iPhone into a portable data collector for the RACHEL network — a global initiative by World Possible that brings educational content to communities without reliable internet access. By visiting RACHEL hotspots and carrying their usage data back online, you help researchers, educators, and program coordinators understand how offline learning is happening in the places that need it most.

How it works

When you arrive at a RACHEL hotspot, DataPost automatically detects it on the local Wi-Fi and downloads the device's anonymized usage data — information about which resources are being accessed, how often, and at what times. The data stays safely on your phone until you reach an area with internet, where DataPost finishes the trip by uploading everything to the central gateway. You are the link that keeps the data flowing from offline classrooms to the people working to improve them.

Key features

• Automatic RACHEL detection on Wi-Fi • Continuous monitoring of both RACHEL and internet connectivity • One-tap sync with real-time progress tracking • GPS tagging on every transfer for delivery verification • Secure Google Sign-In for courier identification • Personal activity dashboard with delivery history, success rate, and average delivery time • Designed to work in low-connectivity environments

Who it's for

DataPost is built for couriers, teachers, NGO workers, volunteers, and anyone traveling between connected and underserved areas who wants to support the mission of accessible education. Whether you pass through a school once a week or visit dozens of RACHEL devices across remote regions, every sync you complete brings valuable insight back to the people working to expand offline learning programs.
