⚡ CORE FOREGROUND SERVICE USAGE
LinkUp utilizes foreground services to ensure the reliability of essential safety features:
● Real-Time Proximity Alarms: To alert you the moment a friend is nearby, LinkUp uses a foreground service to monitor location coordinates in the background. This ensures proximity logic functions even if the screen is closed or you are using other apps, providing accuracy that standard background updates cannot offer.
● Uninterrupted Voice Calling: To keep audio calls connected while you multitask, we utilize 'microphone' and 'phoneCall' foreground service types. This prevents the OS from terminating your call when you navigate away from the app.
A persistent notification is always displayed when these services are active to provide full transparency and user control.
