Meteorium ("the App") is an astronomy visualisation app provided by Avellsky.
None. The App does not collect, transmit, or store any data, including personal information. There are no accounts, no ads, no tracking and no analytics.
The App connects to the network only in the cases below, and none of those requests carries anything about you:
Apart from that, the App makes no network connections: the orbital computation and the rendering all happen on your device.
Meteorium Pro, an auto-renewable subscription, is bought, renewed and cancelled through the App Store (Apple) or Google Play (Google). The App learns only whether a subscription is active; it never receives payment or account details. The purchase status is checked through your device's store service.
Exporting an image, a video or data opens your device's share sheet (a save panel on the Mac). Where the file goes is your choice; the App is not involved.
Opening a link in the App (the manual, for example) hands off to your device's browser; anything that follows is the browser's traffic, not the App's.
Preferences (such as display settings) and downloaded Pro data are stored only on your device, and are removed when you delete the App.
The App can be used by people of any age and collects no personal information from anyone.
