Help with app datas

[Bastien Chanot]

Hi everyone !

I'm here because i would like to know if you had an idea of how to clear app saves without clear in app downloads.

I'm explaining myself :

I would like to download apps, and open them once to get the download assets and in apps download, and launch them to use it some times, but, with a command or something, clear all saves but keeping these in app downloads.
I disabled google plays game service, so it didn't save in it, i tried to make a snapshot of android once i downloaded theses in app downloads, but some apps, at first launch, making some user ID, and share it with them cloud. so if i back to the snapshot, the game stay where i left it after used them for a while.
If i use the command

pm clear

it correctly clear all the data and it like i launch it for the first time, but don't keeping the in app downloads.

Anyway, i just would like to know if anyone have some idea to how could i make what i'm looking for.

Thanks for your helps.
Best regards, Bastien.
