Is it legal to crawl informations from websites for an App
I have an idea for a App but i dont know if it is legal to crawl the informations i need for my app from websites?
Crawl means: parsing out the informations of a website and put them into my oun database.
So i have my oun server with all this informations wich i can use for my application.

When it is an RSS Feed i think there is nothing illigel to use it. But what when they dont have an RSS-feed? Is it legal to parse the website and "steal" the informations to use it (meaningful) in my oun app?

Thanks and Greetz
