Privacy of data when hosting Q2A on private server

Question

If a commercial enterprise runs Q2A on its own private server, is it guaranteed that no data is sent outside the private network?

For example, is any data sent back to question2answer.org or any external site?

In other words, from the point of view of keeping commercial info private is Q2A suitable for a commercial company to host on its own site ?

Comments

"is it guaranteed that..." => Could you clarify what kind of warranties could a GPL product have?

Good point, I guess "guaranteed" was too strong. I am simply looking for information on whether Q2A is suitable to use internally on a private server inside a company. I couldn't find any details yet in the documentation I read.

I believe only the Q2A core and plugin version checkers go outside. Of course, maybe some plugin might do that as well (e.g.: the facebook login will somehow have to hit facebook, right?)
