https://f-droid.org/packages/com.google.android.gms backend that uses locally acquired WiFi AP data to

resolve user location.

This backend consists of two parts sharing a common database. One part passively

monitors the GPS. If the GPS has acquired and has a good position accuracy, then

the WiFi APs detected by the phone are stored.

The other part is the actual location provider which uses the database to

estimate location when the GPS is not available or has not yet gotten its first

fix. The use of stored WiFi AP can dramatically decrease the GPS time to first

fix.

This backend performs no network data. All data acquired by the phone stays on

the phone and no queries are made to a centralized AP location provider.
