Thanks a lot for you answer duzins, in fact my doubt is about if yahoo has any politic of restriction about the uses of the services. I understand that the services are offered as is and also that yahoo does not have developer support. Just that I don't want to infringe any law in my final project as copyright or something like that.
Also I would like to mention that the services were developed by Yahoo and mention finances.yahoo.com as a data provider.
Hi duzins, with politics of restrictions, I'm trying mean any restriction about the uses of the services. I have been read in at other post that someone else was asking about the uses of services on a commercial app. And the replier's answer was that the only form that yahoo lets use their services is by the uses of the tools developed by yahoo.
In my case Ill will develop an application which is not for commercial uses. Is for an end school project. An important part of the project is not to break any law. For that my interest in knowing about if can I use the yahoo services without any problem.
Also as I mention below, I'll specify to yahoo as owner of the services and as a data provider.
