Déjà Vu - A local RF based back end for the µg Pro

Déjà Vu is an Android component that serves as a local radio-frequency based back end for µg Pro. It works with mobile networks and WLAN/Wi-Fi signals to provide location-related data for UnifiedNlp and microG. Rather than acting as a standalone app for everyday use, it functions as a supporting backend that other software can call for network-based positioning.

The project is intended for Android devices and is described as a mobile and Wi-Fi based network provider. Its role is narrow and technical: it gathers and supplies network reference data instead of offering a full user interface for location services. It is published by n76 and released under the GPL-3.0-or-later license.
