Android Permissions in General geocaching topics Posted March 1, 2011 This makes me a little uncomofrtable, so I have to ask. Why, specifically, does the Groundspeak android app need the following permission: Your Personal Information: read contact data According to Groundpeak, it is to allow you search for caches near locations in your contacts. See here. So if I'm going to visit Fred on Saturday, I can look and see if there are any caches near Fred's house? That's pretty cool, I didn't know it could do that. That is correct.
