You're probably well aware that many mobile apps want to share your data. They need your email address to set up an account, or your location to tag your photos. However, a research team has discovered that at least some of that software is sharing more than you might be comfortable with. On average, 110 Android and iOS apps sent data to three separate internet domains. That's not necessarily a problem by itself, but that info sometimes goes to places you'd rather not send it (say, medical search terms sent to marketers). Also, this info sometimes arrives in combinations that could be used to track your behavior, like your name and location.
