Privacy policy / Personvern

NVIS is a planning tool for available light during night flying, published by Mayday AS. It has no user accounts, no advertising, no analytics and no tracking.

What stays on your device

• Saved places, your planned route and your settings are stored only on your device.
• They are not sent to us, and are deleted if you delete the app or clear its data.

Location

If you allow it, NVIS uses your location to centre the map where you are. The location is used on your device and is not stored by us.

What is sent to our server

To calculate available light, the app sends the coordinates and time of the map area, point or route you look at to our server. They are used to answer that request and are not stored or linked to you. Like any web service, our hosting provider (Vercel) briefly keeps technical request logs (such as IP address and requested URL) for operation and security.

To answer, our server fetches public data from MET Norway (weather), NASA (night lights), NOAA (aurora) and Amazon Web Services (terrain). Only coordinates and time are passed on, never anything that identifies you. Place search is forwarded to OpenStreetMap Nominatim.

Map images are loaded by the app directly from the map provider (OpenFreeMap) and terrain tiles from Amazon Web Services, which means those providers see your IP address, as with any map on the web.

NVIS har ingen brukerkontoer, reklame, analyse eller sporing. Lagrede punkter, ruter og innstillinger lagres bare på enheten din. Posisjonen brukes på enheten for å sentrere kartet og lagres ikke av oss. For å beregne lys sendes koordinater og tid for området, punktet eller ruten du ser på til serveren vår; de lagres ikke og knyttes ikke til deg. Serveren henter offentlige data fra MET Norway, NASA, NOAA og AWS, og stedsøk sendes til OpenStreetMap Nominatim. Kartbilder hentes direkte fra kartleverandøren. Spørsmål: myhre@mayday-as.no.
