Hong Kong SARChecked 18 August 2026

Depends on your industryWork: MediumEnforcement: Active

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
Hardest industry wall: None found.

HungaryChecked 18 August 2026

Yes, with paperworkWork: HighEnforcement: Active

In one paragraph: Hungary has no general rule that data must stay in the country. It runs on the European rulebook: you may send data abroad if you have the right legal paperwork in place. Hungary used to force state registers to be processed on Hungarian soil, but that rule was scrapped in April 2024. The privacy regulator is real, staffed and issuing decisions, though its fines are small by European standards.
The catch: Two things break the easy answer. Since January 2025 a large slice of the economy — energy, transport, banking, health, water, digital infrastructure, waste, manufacturing and most of the public sector — may only use a shared cloud or process data outside Hungary after completing a formal data classification under the cybersecurity law. And an online casino serving Hungarian players must keep its game server inside the European Economic Area, full stop.
Does this apply to me?: Yes. A company with no office in Hungary is still caught if it offers goods or services to people in Hungary or watches their behaviour, because the European privacy rules reach outside Europe. There is no revenue or headcount threshold to hide under. If you have no establishment anywhere in Europe you must appoint a written representative inside Europe, and Hungary is a perfectly ordinary place to put one.High confidence
Can the data leave the country?: Yes, on the normal European terms — nothing in general Hungarian law says data must be stored in Hungary. This is a change worth noticing: the rule that state registers could only be processed on Hungarian soil was repealed with effect from 1 April 2024, and the law that replaced it has no territorial restriction at all. Two sectors override this. An online casino must keep its game server inside the European Economic Area. And any company or public body inside the scope of Hungary's cybersecurity law must finish a formal data classification before it uses a shared cloud service or processes data abroad.Medium confidence
What do I have to do to send it abroad?: You need a European transfer tool before the data leaves, and Hungary adds no extra permit, filing or fee on top. The model is an approved-list one: you may send data to a country the European Commission has declared safe, or you sign the standard European contract clauses and write down a risk assessment of the destination. There is no Hungarian government sign-off, and no Hungarian list of banned countries. For police, security and other work outside the European privacy rules, Hungary's own Info Act sets the conditions instead.High confidence
Who enforces this — and are they actually working?: The National Authority for Data Protection and Freedom of Information, known by its Hungarian initials NAIH, and it is genuinely working. It has published decisions right through to May 2026, released its report on 2025 activity on 30 March 2026, and issued public statements in July and August 2026. Its president is Dr Attila Peterfalvi. The catch is size, not activity: a typical fine is small — two million forint, roughly six thousand dollars, in an April 2025 data-security case.High confidence
How long must I keep it, and when must I delete it?: Hungary pushes hard in both directions. The floor is long: accounting records and vouchers must be kept for eight years, and health records for decades — the health data law works in periods of thirty years and more. The ceiling is the European rule that you delete personal data once the purpose is spent. When the two collide, the specific statutory keep-period wins, so a deletion request does not empty your ledgers or a hospital's files.Medium confidence
What happens when something goes wrong?: Count at least two clocks, and three if you are a bank. A personal data breach goes to the privacy regulator within 72 hours. A cyber incident at a company or public body covered by the cybersecurity law goes to the national incident response centre, and the European rules that Hungary is copying use a 24-hour first alert followed by a fuller report at 72 hours. Financial firms have a separate and faster set of deadlines under the European operational resilience rules.Medium confidence
What's the trap?: Five things that are not in the summary. One: mishandling personal data is a crime in Hungary, not just a fine — up to one year in prison, two years for sensitive data, three years for public officials. Two: the old rule forcing state data to stay in Hungary is dead, so quoting it makes you look out of date, while the new cybersecurity classification gate is very much alive and most checklists miss it. Three: several cybersecurity deadlines have already passed, so newly in-scope companies are late on day one. Four: an online casino's game server must sit in the European Economic Area. Five: Hungary's freedom-of-information regime can make your contract with a state body public.High confidence
What's about to change?: Three dated items. The Court of Justice will rule on Hungary's sovereignty protection law; the court's adviser said on 12 February 2026 that it breaks European law, and the judgment could land any time. From 12 January 2027 cloud providers across Europe, Hungary included, must charge nothing to move your data out. And Hungary's cybersecurity supervision moves from paperwork to inspections now that the first audit deadline of 30 June 2026 has passed.Medium confidence
