Tears of the Kingdom Interactive Map saves

[EddyTheTeddy]

Hello, I'm currently playing Tears of the Kingdom and I'm using the interactive map from zeldadungeon.net. My cookies are stored and I also see them stored, I'm using safari on my iPhone. But after I closed the app today, on accident all my progress is deleted and I was logged in with this username there.
Is there any possibility to restore my progress?
I've already tried to get to it through my history browser but it didn't work.

Thanks in advance.
