I think part of it is that people often buy pizza out of their neighborhood, so they want a name they know with menu items they can just recite... hence not only national chains but regional chains (e.g. Round Table in CA). I would never have a chain food app on my phone just from a privacy-suck standpoint. For example, here are the permissions the Dominos app wants on Android: This app has access to: Location - precise location (GPS and network-based) Phone - directly call phone numbers - read phone status and identity Photos/Media/Files - read the contents of your USB storage - modify or delete the contents of your USB storage Storage - read the contents of your USB storage - modify or delete the contents of your USB storage Camera - take pictures and videos Microphone - record audio Device ID & call information - phone status and identity Other - receive data from Internet - view network connections - pair with Bluetooth devices - access Bluetooth settings - full network access - control vibration - prevent device from sleeping
