Privacy Policy – RADAR Study Portal

Last updated: 4th October 2025

The RADAR Study Portal is operated by a research team at King’s College London (KCL). The Portal supports mobile health research studies by allowing participants to log in, complete questionnaires, and connect devices such as Fitbit. This page explains how your data is handled.
