Privacy-focused location backends
This cluster comprises privacy-focused Android location backends and apps that derive position from Wi-Fi, cell towers, and Bluetooth beacons, often uploading to open geolocation databases. The dated entries are spread irregularly from 2012 to 2025, with no clear pattern of acceleration or clustering. NeoStumbler, WiGLE WiFi Wardriving FOSS, and Déjà Vu lead on activity signal, though each has 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 12 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
- 01NeoStumbler0★1 moliveopen sourceMobile app that collects Wi-Fi network, cell tower, and Bluetooth beacon locations and submits them to open geolocation services.
- 02WiGLE WiFi Wardriving FOSS0★1 moliveopen sourceMobile app that maps nearby WiFi access points and cell towers, optionally uploading findings to a public wardriving database.
- 03location-auth-portal0★4 mo—ai-builtPortal for location-based authentication to secure access to services.
- 04Local GSM Location - A local cell tower based back0★2 yrabandonedliveopen sourceLocation backend that resolves device position using a locally stored database of cell tower coordinates instead of network queries.
- 05Déjà Vu - A local RF based back end for the µg Pro0★7 yrabandonedlivehand-codedopen sourceLocation backend that estimates device position from locally collected Wi-Fi and cellular signal data without sending queries over the network.
- 06UnifiedNlp (GAPPS)0★9 yrabandonedlivehand-codedopen sourceMiddleware that lets custom Android ROMs use alternative, privacy-respecting location provider backends instead of Google's network location service.
- 07Local NLP Backend0★1 yrabandonedliveopen sourceOffline location provider that builds a local database of cell towers and WiFi networks to determine position without network access.
- 08AltLocationServices0★1 yrabandonedlivehand-codedopen sourceLocation services app that uses BeaconDB's crowd-sourced database to provide indoor positioning without GPS.
- 09MergedWiFiNLP0★1 yrabandonedliveopen sourceUnifiedNlp backend that provides location data from CSV databases, using exponential backoff to save battery.
- 10Trains Locations0★3 yrabandonedliveopen sourceAndroid app that determines device location from train Wi-Fi networks and provides it to the phone's location services.
