Use Playerprefs data from other package?

Hi guys, i want to release a Premium version of my app, but i want it to share data with the free version.
Can i read data from another package ?

Example:
com.test.freeapp
com.test.premiumapp

use the same savedata among these two

The PlayerPrefs class is hardwired to write / read data from a particular location. I believe that location is private per app, so you cannot share it between two games.

You can, however, create another way of saving data into a shared location that can be read by multiple apps (either locally or in the cloud).
