In one paragraph
Hong Kong's privacy law contains a cross-border transfer ban that has never been switched on. It was written in 1995 and, thirty years later, still has no start date. So under the general law you can send personal data anywhere with no paperwork at all. The privacy regulator is busy and prosecutes people, but it cannot fine you directly.
The catch
The free-for-all stops at three doors. Licensed securities and futures firms need written permission from the markets regulator before their records live only on servers outside Hong Kong. Government departments are told not to put sensitive or personal information on public cloud at all. And data coming the other way, from mainland China into Hong Kong, is tightly controlled by mainland law, not by Hong Kong law - that is the wall most companies actually hit.
Does this apply to me?
Yes, it can reach you with no office in Hong Kong. The privacy law bites on whoever controls the collection, holding, use or processing of personal data in or from Hong Kong, so a foreign company running a Hong Kong-facing service is caught. There is no revenue or headcount threshold to fall below, no register to join, and no requirement to appoint a local representative. The anti-doxxing powers go further still: the regulator can order an overseas platform to take material down.High confidence
Can the data leave the country?
Under the general privacy law, yes - freely, with nothing to sign. The one section that would have restricted transfers abroad was written into the law in 1995 and has never been brought into operation, so today there is no legal control on personal data leaving Hong Kong. Industry rules are where the real limits sit, and there are fewer of them than people expect: the securities regulator is the main one, and government departments have their own restriction.High confidence
What do I have to do to send it abroad?
Nothing. There is no approval to seek, no standard contract to sign and no government list to check before personal data leaves Hong Kong. The model on paper is an allowlist - the regulator would publish a list of approved destinations - but because the section was never switched on, that list has never been issued and is empty. The regulator does publish a voluntary guide and encourages firms to build the safeguards now, but that is advice, not law.High confidence
Who enforces this — and are they actually working?
The Privacy Commissioner for Personal Data, and it is genuinely busy. By the end of December 2025 it had issued 2,104 orders to 57 online platforms to take down 33,743 doxxing messages, opened 519 criminal investigations and arrested 81 people. But there is a catch that changes the risk picture completely: the Commissioner cannot impose a fine for breaking the privacy principles. It serves a notice telling you to fix the problem, and only ignoring that notice is a crime.High confidence
How long must I keep it, and when must I delete it?
There is a hard ceiling and almost no floor in the privacy law itself. You must erase personal data once it is no longer needed for the purpose you collected it for, and failing to do so is a criminal offence carrying a fine of up to HK$10,000 (about $1,300). The privacy law sets no minimum keeping periods; those come from tax, company and anti-money-laundering law instead. Where the two pull against each other, the specific keeping duty in the other law wins, and you delete once it expires.Medium confidence
What happens when something goes wrong?
For a normal data breach there is no deadline, because there is no duty. Telling the Privacy Commissioner about a breach is voluntary in Hong Kong - the regulator asks you to do it as good practice and gives you a form, but no law compels it. That is unusual and it is changing: since 1 January 2026 operators of designated critical infrastructure must report computer-system security incidents, so those firms now have a real clock while everyone else has none.High confidence
What's the trap?
Five things that catch people out. First, marketing mistakes are crimes here, not fines - using someone's data for direct marketing without the right consent can mean five years in prison. Second, the regulator cannot fine you, so people assume the risk is low and miss the criminal exposure entirely. Third, Hong Kong sets no age at which a child can consent, so there is no simple number to code into a sign-up flow. Fourth, licensed securities firms need written permission before their records live only on overseas servers, and two named people who live in Hong Kong must be able to unlock them. Fifth, the dormant transfer section, if ever switched on, would also catch data moving between two foreign countries when a Hong Kong company controls it.Medium confidence
What's about to change?
Nothing is scheduled to land in the next twelve months that we could confirm. The critical infrastructure security law already started on 1 January 2026, and the government's guideline for generative artificial intelligence was revised in December 2025. The thing to watch is not a new bill. It is a switch the government has held for thirty years: the cross-border transfer section can be brought into force by a simple commencement notice, with no consultation and no new vote.Medium confidence

United StatesChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
In one paragraph
In general the United States lets data go anywhere. There is no national privacy law and no permit is needed to move data abroad. Two things bite hard. Six countries are effectively off limits for large amounts of sensitive data, with prison sentences attached. And anything connected to government work must physically stay on American soil.
The catch
The open headline stops the moment you touch one of six areas: government contracting, police records, federal tax records, defence technical data, telecom licences, and bulk sensitive data flowing to China, Russia, Iran, North Korea, Cuba or Venezuela. Also note that the rule that actually binds you is almost always a state law or an industry regulator's rule, not a national privacy act. There isn't one.
Does this apply to me?
Yes. American rules reach a foreign company with no office in the country. California's privacy law applies to any for-profit business that 'does business in California' and crosses one of three thresholds, and physical presence is not one of them. The children's rule covers foreign websites aimed at American children. No state and no federal law requires you to appoint a local representative — a real difference from Europe.High confidence
Can the data leave the country?
It depends entirely on your industry, so the single national answer is misleading. For ordinary consumer or employee data, yes — send it anywhere, no paperwork. But six sectors have hard walls. Government contracting, police data, federal tax data and defence work require the data to physically stay in the United States. Telecom licences restrict which foreign staff may even look at records. And for anyone, sending large volumes of sensitive data to six named countries is now a crime.High confidence
What do I have to do to send it abroad?
For ordinary data, nothing. No standard contract, no government approval, no destination approval list. The model is a blocklist and it is now populated: six countries are named. Before you move large volumes of sensitive data, your only real job is to work out whether a country of concern, or a company or person they control, could end up with access — including through a vendor, an investor or an employee.High confidence
Who enforces this — and are they actually working?
Nobody, and everybody. There is no national privacy regulator. Instead the consumer protection regulator, the health department, the securities regulator, the communications regulator, the Justice Department, all fifty state attorneys general and one dedicated state privacy agency each enforce a slice. Almost all of them are visibly working right now. The one exception is the new national data transfer programme: it is staffed and issuing guidance but has published no enforcement action yet.High confidence
How long must I keep it, and when must I delete it?
There is a strong floor and a weak but growing ceiling. Investment firms must keep some books for six years and most others for three, with the first two years easy to reach. Health providers keep their paperwork for six years. In the other direction, state privacy laws now force you to publish how long you keep each type of data and to stop keeping it longer than you said, and since April 2026 children's data may no longer be kept indefinitely. Where a keep-it rule and a delete-it rule collide, the keep-it rule wins: every state law carves out data you are required by law to retain.High confidence
What happens when something goes wrong?
Count the clocks — there are at least seven, and they disagree. New York financial firms: 72 hours to the state regulator, and only 24 hours to report paying a ransom. Telecom carriers: seven working days to the police agencies and the communications regulator, and you may not warn customers until seven working days after that. Investment and finance firms: 30 days to affected customers. Health organisations: 60 days. Texas and many other states: 30 days to the state attorney general. Listed companies: four working days to disclose a material incident. The overlap, not any single deadline, is what people fail.High confidence
What's the trap?
Five that cost people their weekend. One: the national data transfer programme carries prison — up to twenty years for a deliberate breach. Two: Illinois lets individuals sue over fingerprints and face scans with fixed damages per person, no proof of harm needed, and that is where the largest privacy payouts happen. Three: the children's rule uses under 13, but several state laws use under 18, so a single age gate will not do. Four: government work means American soil, and police data allows only the United States, its territories, tribal lands and Canada. Five: a rule can be printed in the law book and still be unenforceable, because a court has blocked it.High confidence
What's about to change?
Four things in the next twelve months. The national critical infrastructure reporting rule should be finalised in late 2026, which will switch on a 72-hour incident clock and a 24-hour ransom-payment clock for a very wide range of businesses. California's rules on automated decision-making bite on 1 January 2027. The open banking rule is being rewritten after a court blocked it. And a federal privacy bill is moving in Congress, but it is only a bill and binds nobody.High confidence
