Permissions for Android

I already have this for multi device and want to install it on my new phone, but I read the permissions list and I have a problem with giving my permission to "uses the device's camera(s)". I see absolutely no reason why they need to use my camera(s.) That seems to me a total invasion of my privacy due to the fact that the only thing my camera(s) would see is me! I already have a paid subscription to this and now I am feeling bullied into giving up my privacy to use an application I have already paid for. Can anyone explain to me a logical reason why a corporation should need my permission to "use" my camera?
