Educacional is their provider for some online content (mainly games and similar stuff for young kids to have IT lessons). The grades db, memos and so on are managed by the school itself, and the news as well. Educacional, as far as my app is concerned, is simply a gateway for getting authentication tokens to /those/ services which I actually use.
And, the app that I mentioned in the article (which could be considered as a competitor of sorts) is also being developed by the school itself.
