Unity Cache Max storage size

Unity Engine
1

As per documentation it says 4GiB is the max available storage
Unity - Scripting API: Cache.maximumAvailableStorageSpace.

Is this Cache storage for caching AssetBundles is shared for all Unity applications installed in the device or per application?

It’s per application I think.

Thanks for reply.

Can someone please confirm is it per application or shared across all applications installed on device?
