You can go to Settings->Storage and enable "Expose Database". If you connect your PC to your tablet with a USB cable, you can access mobilesheets.db under /storage/emulated/0/Android/data/com.zubersoft.mobilesheetspro/files. Alternatively, you can change the storage location to something simple like /storage/emulated/0/MobileSheets, and then you can access the file in that directory without any restrictions from other applications. If you need help with the database queries to remove the annotations, let me know.
