Is this app widely considered safe? It seems to ask for an awful lot of permissions and is definitely communicating with a server while it operates I'm aware of who Moxie Marlinspike is and have seen the Open Whisper Systems testimonials, I was just surprised with how much it asks for, has anyone dug through the code to get a feel for the risk profile of letting this app into everything on my phone?
