MoMoAL obtains the location, network state, and call permission of your phone.
Location :
Your location is shown in maps to other users only if you advertise.
Otherwise, your location is stored only on the server. It is never sent to other users.
If you are not an advertiser, you are represented only by a random number on the server. Your identity is not known to the server.
Network state :
When network is turned on or off is known to the app, so that it can more efficiently decide when to and when not to try contact the server.
Call permission :
This is to allow you to click the call menu item to make a voice call to a shop/seller/merchant. The app does not use it for any other purpose.
