I&#39;m creating an app, which country&#39;s law will be applied to it? So, I'm creating an international app; all my team is from Mexico (including me, of course). Which country's law will be applied to it? The app is physically hosted in the United States, but our &quot;main market&quot; will be of course Mexico. I'm not a US resident and have no economic activity inside the US; in fact, I don't even have economic activity in Mexico since I'm 14 years old.
The law of each country where you offer the app for download applies, and you have to consider: Privacy Policy (GDPR in EU, CCPA in California, APPI in Japan, LGPD in Brasil, and more - check each country to be on the safe side) Disclaimer versus AGB/Terms and Conditions (e.g. Germany), not required but recommended Impressum (Germany, Switzerland, Austria) Value Added Tax (VAT) which is taken care of e.g. by Google Play for most countries but not all (e.g. not for Japan) in case the app is not free Consumer Protection Law - applicable (and different) everywhere There might be more, but these are the important ones I am aware of.
When a country makes criminal laws, these laws usually apply to anyone present in the country, and acting in the country. But the country is free to declare that some law might apply to its own citizens in a foreign country, or even foreign citizens in a foreign country. Assuming the laws about using marijuana say nothing about the country, that most likely means it only applies to using marjuana in the country itself. But if the US government decided that taking marijuana in Canada is illegal for US citizens, then nobody can stop them. In this case, Canada would not extradite you (unless Canadian law says that it is criminal for Canadians to use marijuana in another country), and Canadian police would likely not collect evidence. So even if illegal, it would be hard to convict you. PS. The "polygamy" case would be interesting, I think you would have to read the exact wording of the laws in every country. Some countries will say that you can't get married twice, and the attempt to get married a second time while already married is bigamy. In that kind of country you wouldn't have committed a crime within that country. Also, you would only be married to the first wife.
Your VPN scenario is why you have to show the banner to everyone. If you somehow knew beyond any doubt that someone was not in the EU, then you would not have to show a banner, but because you can't verify that, you should always show the banner. Doing so also protects against accidentally violating a similar law in another country; the GDPR is the best-known privacy law, but it is far from the only one. It's good practice to ask for people's permission before collecting their information anyway.
Everything is allowed unless the law says it isn’t Common law systems like the USA are ‘exceptions based’ - the law permits everything except what it prohibits. So, your question is backwards - rather than looking for laws that allow it, you need to look for laws that prohibit, restrict or regulate it. There are laws that regulate this but none that prohibit it.
However, if a website is based in the US and the terms of service say that the law governing the terms is US law, how can GDPR have any affect? It is unlikely that the EU will be able to enforce financial penalties against a company with no presence in the EU. But they could for example block your website in the EU, depriving you of your EU user base. The actual measures that they could or would take against such a company are still unclear, since the GDPR is quite new, and there has been no action under the GDPR against foreign companies. I'm not a lawyer, but I've signed many contracts in my life and nearly all of them have some form of "governing law" clause. The governing law clause in a contract identifies the law that will be used to interpret the contract and to resolve any disputes arising from the contract. The law identified in the clause does not become the sole law governing every aspect of the relationship between the parties, however. For example, a business in New Jersey could have a contract with a client in New York with a clause specifying New Jersey law as the governing law of the contract. But that does not mean that New York's consumer protection law doesn't apply to the transaction.
Neither of those clauses has anything to do with whether a tax on the use of Whatsapp is legal: The first clause tells users that they are responsible for any taxes that may be owed. It says nothing about whether such a tax is or is not legal. The second clause says that users may not charge for Whatsapp services. It says nothing about whether the government may impose a tax for the use of the services. That is all beside the point, though. Even if the TOS explicitly said, "No one may tax the use of our services," that would have no legal effect. Saying that you're exempt from taxation does not make you exempt from taxation.
Obviously, it's not simply illegal to have a business that exchanges currency - legal currency exchanges do exist, after all. But you'd have to be careful if you wanted to open a business that does this. According to 31 CFR 1010.100, you are considered a "dealer in foreign exchange", and thus a "money services business", and thus a "financial institution", if you are: A person that accepts the currency, or other monetary instruments, funds, or other instruments denominated in the currency, of one or more countries in exchange for the currency, or other monetary instruments, funds, or other instruments denominated in the currency, of one or more other countries in an amount greater than $1,000 for any other person on any day in one or more transactions, whether or not for same-day delivery. You are not considered a "money services business" if you do this "on an infrequent basis and not for gain or profit", but you say you want to "open a business" that does this, so this exemption wouldn't apply to you. If you are considered a financial institution, then you must comply with all sorts of anti-money-laundering regulations, including, for example, verifying the identity of your customers, and filing reports with the US Treasury. You would definitely want to hire a lawyer to guide you through the requirements.
Your app is a simple case of copyright infringement. All the Pokémon are copyrighted, the lettering and names are also protect by trademarks. Trying to claim fair use will be outright impossible: you'll use huge portions of the individually protected Pokemon (the iconic ones like Pikachu) and you are usurping a market they are already in. They have given licenses for apps (Pokemon Go). Pokemon are artistic and some form of fiction. The last straw might be if you'd do a rather obvious parody, but even then, I see no way to show Fair Use with what you stated. No disclaimer can change that, and publishing your work might open you to a huge lawsuit with damages for each individually protected Pokemon you infringed on. With between 750 $ minimum and 150,000 $ absolute upper limit per infringed item (last is for willful infringement), you don't want to infringe on Pokemon, as you could be very easily liable for a number in the 6 to 9 digits! Even if Nintendo might only try to get the statutory damages for all the 900 Pokémon, that is a number of at least 675,4000 $. And that's before looking at Trademarks. Pikachu has about 6 live word marks and there are 111 different Pokémon trademarks filed (some expired or dead)!
