BeaconDB is a new platform for opt-in only, privacy-friendly data collection that is ethically sourced and abuse-resistant. Users can contribute by submitting data through apps like NeoStumbler and Tower Collector. The data is aggregated and shared under a public domain license, with information handled according to a privacy notice. BeaconDB is experimental and should not be used for critical services, but Android users can test it through microG Settings. Developers can access the API endpoint for geolocation requests, but large-scale use is discouraged due to infrastructure limitations. Joel Koen is behind this initiative, and more information is available on Codeberg and through Matrix and IRC chat.
