I use Blockfolio too as it seems to be the most convenient app out there right now. Should there be any concern for tracking and privacy info?
mmm I am not sure that I am concerned, you really don't put any personal information in the app right? You just put in info regarding your investments. I guess if someone found your phone, and unlocked it, they could open up and see your porfolio of investments. But then again I am don't really know for sure! Hackers are pretty smart these days. haha
