Probably a dumb question, but I"m using a SharedPreference with a few different names "MyPrefs1", "MyPrefs2" etc.

I'm assuming this is restricted to my app. i.e. if some other app tries to use the same name, it won't overwrite my values

I pretty much believe my understanding is correct, but the name "SharedPreferences" seem to indicate that it can be shared between apps? (is it for Sharing between activities?)
