Hi, no worries, I'm still here
There's no in-game method to extract the save data and I don't think dev will implement such a feature, at least not soon, but it is possible by using your PC and connecting your phone via USB cable
There was someone that posted a guide how to do it in one of the comments here on itch on the main game page or you can join the discord and check the other guide there, some actually tried the discord one and successfully extracted / transferred save data
if you decide to join, check pinned comments in #support channel or ask (preferably in English) and either me or someone else will try to help you
Cheers
