IS IT SAFE TO MANUALLY INSTALL AN APP?
All apps have the ability to access your device, whether they are from Playstore or not. What matters is the 'Permissions' the app asks for during install.  Make sure the app is not asking for permissions it does not need. Nature Explorer only requires internet access for download of your topics and thereafter works 'offline' and without internet.
Download and unzip the Windows version to your desktop. Install it by double-clicking the exe program. That's it!
