You can either use the “Report a bug” feature available in the sidebar while the game is running. This attaches the savegames to a e-mail.
Or… this depends. Either in the game directory (SaveXX.lsd) or when the game directory is not writable (SD card) the saves are in /easyrpg/saves (there should be Aedemphia or Data/Aedemphia or something like this)
