Landblink is built on work other people did first. This page says whose, and under what terms.
The basemap is Natural Earth 1:110m — land, lakes, country boundary lines, populated places and country labels. Natural Earth is in the public domain. Map rendering is MapLibre GL, BSD-2-Clause.
The airport table is a trimmed export from OurAirports, which is public domain. The airport-to-timezone mapping is derived from an OpenFlights snapshot under ODbL 1.0 / DbCL 1.0; the retrieval date and file digest are recorded in the app's own airport_timezones-LICENSE.txt. The city gazetteer is derived from Natural Earth populated places.
Orbit products come from public analysis centres — GFZ, Geoscience Australia, and NASA CDDIS where the operator's credentials allow. Broadcast almanac and ephemeris come from the phone's own receiver. Satellite photographs are used under their individual licences, which the app lists in full on its Credits screen with a link to each source; most are public domain or Creative Commons from Wikimedia Commons.
Route weather and winds aloft come from Open-Meteo, whose data is CC BY 4.0. Turbulence is an Ellrod-style index computed by Landblink from those winds. It is an estimate, and the app says so wherever it is shown.
Boarding-pass barcodes are decoded on-device by ML Kit's bundled barcode scanner. The pass is parsed by Landblink itself, and the parsers do not read the passenger name or the booking reference — that is a property of the code, not a promise.
If something here is wrong, or a licence is missing, say so and it will be fixed.
