Depending on your device Star Chart may request you to approve certain permissions. Below is a list of these permissions and why Star Chart asks for them as well as how they are used.
However, in general you can rest assured that we do not trade, store, track, disseminate, or otherwise use your data in any way other than to help make your experience better. We believe your data is yours and you should be in control of whom has access to, and how your data is used.
If at some future point this changes, you will be explicitly informed within the app and / or this document will be updated with precise details of what we do with data.
Star Chart uses your device's location data (GPS data) to determine where on the Earth you are located and therefore what night sky objects are visible to you from your current location. Denying access to location data means that you will not get an accurate reading of the night sky unless you manually set your location data in some other way. If permitted, Star Chart may use and record your location data on your device. However, all location data is solely used to calculate a visual representation of the night sky / celestial objects based on your current location. We do not collect any data nor do we transfer any data to a third party.
**** None of your GPS data is distributed outside of your device nor used by us in any other way ****
On some platforms, Star Chart allows English speaking users to control Star Chart with Voice Commands. These voice commands are interpreted by the OS's Voice API. On Android, using the Voice API for voice commands requires us to ask all users in all territories to give permission for Star Chart to 'Record Audio'.
We do not collect any audio from your device unless you specifically trigger the voice command function, and we do not share that data with anyone else other than as required by the API to interpret the audio commands. For example, some voice command software sends audio command snippets to a server where they are analysed & interpreted before the results are returned to the app so that your commands can be actioned.
Please note that Star Chart respects your privacy. We do not receive any data from your device, nor do we send any data to a third party - except:
