LocalGsmNlpBackend

UnifiedNlp location provider (local GSM database)
New in version 1.4.22
- Update Ukrainian Translation.
- Update build environment

UnifiedNlp (no GAPPS) backend that uses local GSM data to resolve user location.

A facility in the setting menu allows you to create a database using data from OpenCellId and/or Mozilla Location Services CSV files. Alternatively, the on-phone database can be generated in advance via the lacells-creator scripts that gather tower information from those two sources, too.

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.

Packages

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
