Can't transfer save from android to pc

[Mokonamadoki1]

i've been trying to transfer my birth by sleep save from android to pc but it seems like there isn't an actual save file for the game, in which case how have i been saving????/ like, i checked the saves folder but only my project diva saves are there. also birth by sleep is the only game that i have save states for and it looks like there aren't any files for the save states either.
