You ought to read the whitepaper I linked. I absolutely take privacy seriously in both my job and my private life. What is kept on your phone in the DT3P/Gapple scenario is neither location data nor even a list of "contacts". What it does keep is a list of temporary (15 minutes or less) ids for the last two weeks - this does not reveal how many people youve been in contact with, much less who. It is as privacy respecting as it gets.
