What is illegal about my app? I want to create an app similar to the 4shared Music app that enables downloading MP3 files stored on my server. Features Serves all mp3 files from host server Distributed via Google Play Store Music library searchable by title or artist name Annual subscription fee for unlimited downloads Free live music streaming MP3 files accessed from content creator or wholesale distributor via API What might be illegal about what I have described? What might it be wise to consider when building and distributing this app?
You need to make sure you are not infringing upon the copyrights of the music owners. There might be other things you need to do. But at a minimum you will need to have agreements with the music owners that specify the timing and amount of the payments they will receive for allowing you to distribute their music. And any other ancillary terms you or they might want to include depending on the details of your business model.
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.
This is not &quot;unfair competition&quot;. You are allowed to ask people for their views and take them into account in designing software, even with the specific intent that it compete successfully with existing software. In the US you have a protected right to do that under the First Amendment. If the chat site where you asked is run by the developer or owners of the app, they can ask you to avoid such question there, and even ban you from the site if they choose, because it is their site. But if you went onto a public site (like Stack Exchange, say, or Quora) the app owners would have no right to insist that you not ask for such opinions. The degree to which the design or interface of an app or other software may be protected against imitation is a complex one, and depends on the country involved. But widely known and used features such as a 'like' button, message threading, or a comment section are almost surely not protectable. Listening to users of existing simile products and getting their ideas on what works well and what is lacking is generally a good idea, and is in no way &quot;unfair&quot;.
&quot;Any perceived compliance or non-compliance of other developers’ apps does not have any bearing on the compliance of your own apps.&quot; Could this mean that Google Play's policies are applied differently for different developers or apps? No, it means that you can't break the rules even if others are breaking the rules or you think they are breaking the rules. I think it is worth noting that those apps are for the Indian market. I don't know which one you are in, but google will have different rules for different countries to comply with various regulatory requirements.
First of all derivative works are not exactly "illegal". They are fully legal if the owner of the copyright in the original work has given permission. If no permission has been given, they may be copyright infringements. But they may fall under an exception to copyright. Under US law, the most common exception is "fair use". See this question and answer for more on fair use. But particularly relevant in this case is that a parody is usually a fair use, although as in every fair-use decision, there is pretty much no clear-cut, hard&amp;fast rule on what is and is not fair use. In the UK and much of the EU (or maybe all of it, I am not sure) there is a somewhat similar concept known as "fair dealing". It is also an exception to copyright. So it is possible that such works fall under fair use, fair dealing, or another exception to copyright, or that the rights-holder has given permission. Secondly, copyright infringement is a tort, not a crime, under most circumstances. It is enforced when, and only when, a copyright-holder chooses to take action, sending a take-down notice or copyright complaint, of filing suit for infringement. Some rights-holders choose as a matter of policy not to take such actions, thinking that such derivative works actually benefit them. That is their choice to make. Some rights-holders don't have the time or money to track down and take action against most infringements, and will only act if they think the derivative work will in some way cost them a lot of money or harm their reputation. Some rights-holders may just not have heard, yet, of specific possible infringing derivative works. As for Acta2, it has not yet been approved, the Wikipedia article linked in the questions says: In order for the text of the directive to become law in the EU, it must be approved by the European Council on 9 April 2019 The article also mentions significant continuing opposition. If it is approved, it is not clear, to me at least, how it will affect sites hosting such content, nor how it will interact with the copyright law of individual EU nations. If approved, it will no doubt take some time before enforcement is widespread. And of course it will only apply when EU law applies. If both site and author are outside the EU -- say if both are from the US -- it seems that it could not apply.
Let's examine some laws that may apply to your case Digital Millennium Copyright Act (DMCA) There are criminal penalties for willful infringement for personal financial gain. If you are only sending it to one family member through a private communication (eg not posting it publicly) and not selling it and one copy of the music video has a retail value of $1,000 or less then there will be no criminal penalties. But you may be liable for civil penalties. Computer Fraud and Abuse Act (CFAA) Courts have ruled that ToS violations do not constitute unauthorized access (or exceeding access) so you aren't in violation of the CFAA Civil Liability By downloading a video off of YouTube you are in violation of their ToS. There isn't enough prior case law for me to tell you the outcome here. You may be committing some sort of civil wrong by the act of downloading. In addition, you are distributing a copyrighted work without permission which would open you to more civil penalties. The real question is how likely is it for this to be enforced? Not likely.
Quoting content may or may not constitute copyright infringement, depending on the various factors that go into the fair use defense. Short quotes which are made for the purpose of discussion, research and commentary and not for copy would be squarely in the domain of "fair use" under US law. That means that the copyright owner would not succeed in suing you for quoting them: under the statutory mechanism for recognizing his right to his intellectual product, there is a limit on how much control he can exert over your behavior (since the two of you have not worked out some kind of agreement -- copyright law creates rights even when there is no contract). As for Facebook, you have a contract with them, embodied in the terms of service. You have been given permission to access material that they host (permission is required, under copyright law), and their permission is conditional. It says "you may access stuff on our platform only as long as you do X": if that includes a clause "don't be nasty", then that limits your right to speak freely and be as nasty as you'd like. If it says "don't quote even a little", that means you cannot quote even a little, even when you would have the statutory right to quote a little (or, to be nasty). Fair use would mean that you can't be sued for copyright infringement of the stuff that you quoted a little of. You can, however, be expelled from Facebook. You probably cannot be sued for "accessing Facebook without permission". There is a federal law against unauthorized access of computer networks, and there was a failed attempt to construe violation of a TOS as "unauthorized access" – it isn't. But accessing Facebook necessarily involves copying (that's how computers work), and there is no "fair use" defense whereby everybody has a fair use right to access Facebook. Theoretically you could be sued for copyright infringement, for accessing Facebook's intellectual property without permission. Also, Facebook can rescind your permission to access their content (see this case), and once you have been banned, it is a crime to further access their network. This assumes that there is no overriding limit on contracts that would nullify a no-quoting condition. There is no such limit on contracts in the US, so such a contract would be enforceable. There is also nothing illegal (unenforceable) about a TOS which prohibits automated methods of access.
No. You may not do this. As your post points out this is a blatant copyright violation. It isn't remotely in the realm of fair use.
