One area needs improvement, the others are perfect. Please do not prompt to start background location permission every time you open the app. First, I don't like the software to read my location. I can use googledrive to synchronize. Second, this prompt pops up every time I open the app, which is a bit annoying. I suggest to make a switch option, one with local location and one with Google Cloud synchronization, instead of frantically prompting you to turn on GPS! THANKS!
