I like Parallel and been using it for tests but I am not sure about the terms.

IANAL but think this is to remind you that fragments of text it returns to you after pulling them from various sites in response to your query are protected by whatever copyright notices might be found on those websites. Seems reasonable to me.
As it written it makes part of your agreement with Parallels not to use anything provided via the service without the prior consent of the content owner even if it doesn't violate any legal rights to do so. It may merely be poorly written, but I wouldn't rely on that.
