The personal data collected by Map Marker falls under 3 categories:
The data is collected by Map Marker when you input the data manually or import the data as files or though other apps sharing features into Map Marker. When you grant Map Marker access to your cloud account data, Map Marker will use that access by reading from or writing to your cloud account data.
Map Marker uses the data locally on the device with the different Map Marker features (displaying the markers list, displaying markers on the map, etc.). When you grant Map Marker access to your cloud account data, Map Marker will use that access to search for existing map files created by you or shared by others with you. When syncing map data, Map Marker will use the access to your cloud account data to download it on your device in order to be able to display it in the app.
Your data is stored by Map Marker locally on the device, or into your cloud account data if you choose to sync your data into your cloud account.
Your data lives on the device and on any cloud platform you explicitly configured Map Marker to sync to.
The data is kept on the device or on the cloud platforms as long as you don't delete it manually.
Map Marker does not share your data externally unless you perform explicit actions to share or sync your data. In the case of you manually sharing data from Map Marker, the exported data could be sent to any app on the device you choose to share with. In the case of sync, Map Marker allows you to configure an automated sync with some cloud storage platforms: your data is then shared by Map Marker with those cloud storage platforms.
Currently Google Drive or Dropbox. When you grant access to Map Marker to a cloud platform, that access is used solely to read/write geographic synced data between the cloud platform and your device, and for nothing else.
