Based on the fact that you mention a 'Save' button, I think you would rather save this data to SharedPreferences or an SQLiteDatabase.

I am unsure of what it would mean to 'save' some data to another Activity and not start it.

With your data in a persisted state, you should be able to access it from any one of your other Activity's, which is what is sounds like you are after.
