## What is JTrack Social?

JTrack Social is a research application developed for clinical and scientific studies in the field of digital health and neurological research.

With the informed consent of study participants, the app collects fully pseudonymized and privacy-preserving smartphone and wearable sensor data during everyday life, including:

• Number and duration of phone calls and messages  
• Physical activity and mobility patterns  
• Smartphone app usage behavior  
• Health and wellness indicators from connected wearable devices  

The collected data is used exclusively for scientific research purposes and aims to support the early detection, monitoring, and better understanding of neurological disorders such as Parkinson’s disease and dementia.

JTrack Social is intended for use only within approved research studies and requires a valid study invitation.
