General App Questions

I often times have general questions about apps and I can't seem to find a good place to ask them on this forum, therefore I made this thread for that purpose. If this is in the wrong place sorry about the inconvenience.


Does anybody know how skygrid can access your information between devices without requiring you to use a username or password? For example I've had skygrid on my iPad for quite some time and I have chosen the sections that I wanted to follow, then recently i downloaded it on my iPhone and all the sections that I followed were automatically within the app without adding a username or password.
