Roastime files

I have not been able to sync roastime and roastworld for a while and I am not sure why, as I expressed in my previous thought, so I though to backup the roast and recipes I got and upload them in another computer and that try to sync it but I don’t seem to find the file of Roastime , I am not really sure where they are but they must be somewhere considering to try to sync to roastworld I logged out and logged in again and if they weren’t in the compure but just in the cloud I would have lost all my old roast.
Can anyone help me?
