title: Is it legal for my app to "crawl" websites and use their information?
body: <p>I have an idea for an app but I don't know if it would be legal to implement it. Can I "crawl" information my app would use from assorted websites? For the purposes of this question, "crawl" means parsing out information on a website and storing it in my own database. This way, I would have my own server with all the information I need for my application to run.</p>
  
  <p>I think there is nothing illegal about crawling RSS feeds. But what if the website I want information from doesn't have an RSS feed? Is it legal to crawl that website?</p>
