None. Astrarium does not collect, store or transmit personal data. There are no accounts, no analytics and no advertising SDKs.
Location (When In Use) is used solely to compute the sky visible from where you are. The computation happens entirely on your device and your position never leaves it. If you decline location access, the app remains fully usable: choose an observing site from the bundled list or type in a latitude and longitude.
The app contacts the network only when you press one of these buttons:
Each downloads published data and uploads nothing about you. If you never press them, the app makes no network requests at all.
Display settings, the observing site you chose and any orbital elements you downloaded are kept on the device. Deleting the app removes them.
The app is suitable for all ages and collects no personal data from anyone.
