No. All the app files are deleted. You can store values in the keychain. This is the only local place that persists after the app is uninstalled.

1)add iphone to selected libraries
2) dim p as phone
3) p.keychainput("key","Value") ' This will add a value to keychain and even the app is removed you can retrieve
4) to retrieve use : p.keychainget("key")

Thats all
