Displaying a website in a webview inside a mobile application - copyright infringment Is it a breach of copyright to create a mobile application which simply displays another website in a webview as it is available online?
No. That would be in no way a bigger breach of copyright than creating yet another web browser.
No It says right on the page you linked: These downloads are not public domain, as they are parts of content that has already been licensed and distributed. Although using these downloads may be permissible as long as the project itself falls under the rule of "Fair Use," it is ill-advised to use these downloads for any project intended for profitable gain or commercial advertisement, unless otherwise stated by Kyutwo.com.
It is hard to say: this article sketches the legal landscape. So-called deep linking that bypasses the main page for a site is not believed to be infringement, following the reasoning of Perfect 10, Inc. v. Amazon.com, Inc., 508 F.3d 1146. The URL itself does not have the bare minimum of creativity required for copyright protection, and storing a URL on a computer is not storing the contents that it refers to, so no copy was made in violation of copyright law. It is unlikely that competing theories would develop in other US districts (there don't appear to be any at the present). However, such a link could create secondary liability for infringement, see Erickson Productions, Inc. v. Kast, where a party &quot;has knowledge of another’s infringement and (2) either (a) materially contributes to or (b) induces that infringement&quot;. If I link to a file on a pirate website, I am secondarily liable for that infringement. However, if I link to a legally-uploaded file which the author did not intend to make public, there is no infringement. Copyright law requires permission of the copyright owner, which is more than just &quot;explicit denial&quot;. The problem is that a person can put a file out there and not say one way or the other whether you have permission to copy the file. The US Copyright office says that &quot;A copyright owner must have expressly or implicitly authorized users to make retainable copies of a work by downloading, printing, or other means for the work to be considered published&quot; (let's not care at the moment whether it is important to be &quot;published&quot;). The court may infer implicit permission from a copyright owner's conduct, but there is no rule &quot;if it's on the internet, you've granted permission&quot;. A rights-owner may make a valiant but insufficient effort to block access to the work (except via a password), so in that context, the courts would infer that the rights-owner had not given permission, therefore the copying is infringing and you have secondary liability for your direct link to the material.
You don't have to, but you probably want to for a couple of reasons: It's courteous, and in the spirit of open source It's someone else's work, and you're using it. The least you can probably say is &quot;thank you.&quot; It will also probably help you stay in the clear: since you're using software in binary form, where the notice isn't immediately accessible, then by providing a copy of the license, you respect that licensing term in another way. It tells your users what's up with the program Let's admit it, having the license accessible to the users tells them what's in the program and so on. It's another way of providing attribution, like I listed in the first reason above. Many apps, desktop and mobile, have a screen or panel to indicate the projects and licenses that they use. They don't have to be straight in the user's face, they can be a little button in the &quot;About&quot; screen of the program. To answer a little confusion: the binaries are still a derived form from that source code. Analyse the heading: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. The software is still there, it's just there in a different form, a compiled form. Therefore, the copyright and permission notice should probably stick around, even if it's just a file somewhere.
I've found Google's filtering based on licence to not be very reliable, at least not reliable enough to trust from a practical legal perspective. Using a photo that you don't own the copyright to is a risk. You may be infringing copyright by doing so. The owner may eventually ask you to stop, or they may sue you for damages. Further, some copyright infringement is criminal 17 USC 506. In my opinion, it would be unwise to use a work commercially that you don't affirmatively know you have permission to use.
The images and text are copyright (if they are). What Google does with them is fair use/dealing. It works like this: if Google's bot can find them then you (the owner) have put them on the World Wide Web presumably because you want people to see them, effectively you have put them on public display. Google is assisting you in that endeavour by enabling people who are looking for what you are displaying to find it. Their use of your material enhances its value to you which is a rock solid defence. If you don't want your stuff on public display then a) don't put it on a public part of the web - there are plenty of private cloud storage facilities or B) stick a file in your website that tells bots not to index it.
When the question is "Can I be sued for..." there can't ever be a really useful answer, because anyone can be sued for just about anything. The suit may be tossed as pointless early in the process, but it can be filed. That said, could there be a valid ground of suit against a developer for creating a scraper? Possibly. Scraping a site could be against the site's TOS. It could be largely a way of committing copyright infringement. It could be unlawful in some other way. For most sites, scraping is not unlawful. Google does it all the time. If there is no legitimate use for the scraper, or very nearly none, so that any user is likely to be acting maliciously and unlawfully, and if the developer knows this, or any reasonable developer should know this, then the developer could possibly be found liable for the illegitimate actions of those who use the scarper. If there is a legit use for the scraper, or the developer would plausibly think that there is, then such development is not illegal, and a successful suit against the developer is unlikely.
Content posted to the web is usually openly accessible to all (unless protected by a password, paywall, or similar restriction). But that does not mean it is freely copyable by all. Such content is protected by copyright in just the same way as if it had been published in a book of essays by various contributors. Unless the copyright holders (who are likely to be the original authors, but might not be) give permission, or an exception to copyright applies, copying such content would be clear and obvious copyright infringement, and any copyright holder could sue for damages. Permission could be given by publishing the content under a permissive license, such as a CC-BY-SA license, or any of many other available permissive licenses. Or a would-be reuser could find the copyright holders and ask for permission. If the holder cannot be found or identified, or does not respond, then no permission has been granted. In the US the main exception to copyright is fair use. See this answer and other threads with the fair-use tag here for more on fair use. Since the question seems to contemplate using the whole of the posted content, since it might well damage any potential market for that content, and since the use does not seem to be &quot;transformative&quot;, nor used for criticism or comment, a finding of fair use for this situation seems unlikely. But Fair use findings are very much fact-driven, and the exact facts do matter. Thus I cannot be at all sure whether a court would find this toi be fair use or not. In other countries there are a variety of exceptions to copyright, and I have not come close to reviewing them all. But none of the ones I know of seem to apply to the situation described in the question. Many are narrower than the US concept of fair use. I fear that without permission, copying this content would be infringement. However, it would not be infringement to create a site that includes a link to the existing content, and a summary or description of that content, along with new content, including comments on the old, with brief quotes to indicate what is being commented on.
