No, the database can be accessed from anywhere via rest API of Appery.io db.

I think you won't have problems here.

And this should not be a problem too. Knowing the ID of the database, the name of the collection and maybe a master key (please read more about master key here: http://devcenter.appery.io/documentat... ) you can get all the data from the collection http://devcenter.appery.io/documentat...
