South KoreaChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Aggressive
In one paragraph
South Korea's privacy law bans sending personal data abroad unless you have one of five grounds. The usual one is a separate consent, ticked apart from every other consent. Since September 2025 the 30 European countries need no extra paperwork. But banking, health records, government cloud and detailed maps have hard walls no consent can unlock, and the regulator fines foreign companies often.
The catch
The 'get consent and send it' headline stops being true the moment you touch six areas: bank and payment systems, financial customers' national ID numbers, hospital records, government cloud, detailed mapping data, and personal location services. In those areas the data or the machine holding it must physically sit in South Korea, and in the government cloud case so must the people who run it.
Does this apply to me?
Yes. The regulator fines companies with no Korean office. In July 2026 it fined TikTok's Singapore company and two Apple companies based in Ireland and Singapore for collecting Korean users' data and sending it abroad without a proper legal basis. If your worldwide revenue was 1 trillion won (about $720 million) or more last year, or you held data on an average of 1 million or more people in Korea per day over the last three months of last year, you must appoint a representative in Korea. Since April 2026, if you already own or control a Korean company, that Korean company has to be the representative.High confidence
Can the data leave the country?
In general yes, but only if you have one of five grounds, and the usual one is a separate consent that the person ticks apart from every other consent. Since September 2025 you can also send data to the 27 European Union countries plus Norway, Iceland and Liechtenstein with no extra step at all, because the regulator has formally accepted their protection as equal to Korea's. That is the only such list, and no other country is on it. Six industries override all of this and are covered below.High confidence
What do I have to do to send it abroad?
Korea does not police the destination. It polices your paperwork. There is no banned-country list and no approval application to file: you pick one of the five grounds, and for most companies that means asking each person for a separate transfer consent that lists what goes, where, to whom, for how long and how to refuse. The one destination list that exists is a positive one, and it holds exactly 30 countries: the European Union plus Norway, Iceland and Liechtenstein. Send data anywhere else and you also have to keep security measures, a complaints route and a dispute process in place, and write the transfer into your contract with the recipient.High confidence
Who enforces this — and are they actually working?
The Personal Information Protection Commission, chaired by Song Kyoung-hee, and it is one of the busiest privacy regulators in the world right now. In July 2026 alone it fined the telecoms company KT about 54 billion won (roughly $39 million) over a data breach, fined TikTok about 10.3 billion won (roughly $7.4 million) and Apple about 252 million won (roughly $180,000). It referred KT to prosecutors for obstructing the investigation and asked police to investigate LG U+ for destroying a server before the inquiry started. Finance is separately policed by the Financial Services Commission and the Financial Supervisory Service; health by the health ministry; maps by an inter-agency committee that includes the intelligence service.High confidence
How long must I keep it, and when must I delete it?
Two forces pull in opposite directions. The ceiling: you must destroy personal data without delay once you no longer need it, and destroy it so it cannot be recovered. The floor: other laws make you keep things. An online seller must keep advertising records for 6 months, complaint and dispute records for 3 years, and contract, cancellation, payment and delivery records for 5 years. Almost everyone must keep system access logs for at least 1 year, and 2 years if the system holds data on 50,000 or more people, holds national ID numbers or sensitive data, or belongs to a licensed telecoms carrier. When the two clash, the keeping rule wins, but you must store that data separately from everything else.High confidence
What happens when something goes wrong?
Count two clocks, and in telecoms and finance a third. Under the privacy law you have 72 hours to tell the affected people, and a separate 72 hours to report to the Commission or to the Korea Internet and Security Agency. The reporting clock starts if 1,000 or more people are affected, or if any sensitive data or national ID numbers leaked, or if the cause was someone breaking in from outside. Separately, an internet service provider must report a cyber incident to the science ministry or the same agency immediately. A hospital must also tell the health ministry about a medical-records incident.High confidence
What's the trap?
Five things that will cost you a weekend. One: the children's age line is 14, not 13 or 16, and processing an under-14's data without a parent's consent is a crime punishable by up to five years in prison, not just a fine. Two: hiding or destroying material during a regulator's inspection is itself a crime, and the regulator used it in July 2026. Three: stripping names out of a dataset does not free it. Four: a bank's Korean customers' national ID numbers may not leave the country at all, and any offshore processing of customers' financial transaction data needs a report to the supervisor 30 business days before work starts. Five: if you want to run a personal location service you must be a corporation and be registered, so you cannot serve Korea from abroad with no entity.High confidence
What's about to change?
The privacy regulator started rewriting the rulebook for artificial intelligence. It set up a reform task force on 30 July 2026, ran a public suggestion window from 6 to 31 August 2026, and plans to publish the direction of reform before the end of 2026. Consent-based rules and the block on sending pseudonymised data abroad for research are both explicitly on the table. Separately, Apple's request to export detailed Korean map data has been pending since its deadline was extended in December 2025, and Google's equivalent request was granted in February 2026 on strict conditions, so the mapping picture can move again at any time.High confidence

LuxembourgChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
In one paragraph
For most businesses, data can leave Luxembourg on the same terms as anywhere else in the European Union: you need the right paperwork, not a local data centre. Finance is the exception, and finance is most of the economy here. Banks and insurers are bound by a secrecy duty that is a crime to break, and a bank that runs its accounts abroad must still keep a daily backup inside Europe.
The catch
The relaxed general answer stops the moment you touch banking, insurance or investment funds. There, three things bite: breaking client secrecy is a criminal offence, not a fine; you may only send client information to a supplier abroad if the client has accepted the outsourcing, the type of information and the country the supplier sits in; and if a bank's accounting system is hosted outside Luxembourg it must still hold a full end-of-day backup on premises inside the European Economic Area. Telecoms firms face a separate 6-month duty to keep call and location records.
Does this apply to me?
Yes. If you sell to people in Luxembourg or watch what they do online, the European privacy rules reach you even with no office here. There is no revenue or headcount threshold to hide under. A company with no base anywhere in Europe must appoint a representative in Europe, though it does not have to be in Luxembourg. The extra Luxembourg-only duties in the national law mostly apply to organisations that are actually set up here.High confidence
Can the data leave the country?
In general, yes, with paperwork. Luxembourg has no national law telling ordinary companies to keep data in the country, and European law actually forbids member states from forcing non-personal data to stay put except on public-security grounds. But this is a banking and fund centre, and the finance rules change the answer. A bank or insurer may only hand client information to a supplier abroad if the client has been told and has accepted which country that supplier is in. And a bank whose accounting system sits outside Luxembourg must still keep a full daily backup somewhere inside the European Economic Area.High confidence
What do I have to do to send it abroad?
The model is a European approved-list. Sending personal data outside Europe is barred unless the destination is on the European Commission's approved list, or you put an approved safeguard in place first. The list is real and populated. Luxembourg adds no national permit and the regulator does not pre-approve ordinary transfers. In finance, though, you also need the client's acceptance of the destination country before their information moves.High confidence
Who enforces this — and are they actually working?
Yes, the regulators here really work. The privacy regulator is the National Commission for Data Protection, known as the CNPD. It is staffed, it publishes decisions, and in 2025 it handled 846 complaints, 425 breach reports and 59 investigations. It issued the largest privacy fine ever recorded in Europe, against Amazon in 2021. The financial regulator and the insurance regulator are heavyweight supervisors in their own right, and since May 2026 the telecoms regulator also runs the national cybersecurity regime.High confidence
How long must I keep it, and when must I delete it?
There is a floor and a ceiling, and they collide often. You must keep anti-money-laundering records for 5 years after the relationship ends, patient files for at least 10 years after care ends, and telephone and internet connection records for 6 months. In the other direction, European privacy law says delete personal data once you no longer need it, and the anti-money-laundering law says delete it when the 5 years are up unless another law makes you keep it longer. That last sentence is how Luxembourg resolves the clash: the longest specific legal duty wins, and after that you must actually erase.High confidence
What happens when something goes wrong?
Count four clocks, because they overlap and they start at different moments. Privacy breach: 72 hours to tell the privacy regulator. Telephone and internet providers: 24 hours to report a personal data breach. Cybersecurity incidents at important companies: an early warning in 24 hours, a fuller report in 72 hours, and a final report a month later. Banks and insurers have their own European reporting on top. The trap is that one incident can start all of them at once, on different teams, with different forms.High confidence
What's the trap?
Five things that are not in any summary. (1) Breaking bank or insurance client secrecy is a crime, not a fine, and it survives the end of the job. (2) Your works council can freeze an employee-monitoring project: staff have 15 days to ask the privacy regulator for an opinion, and that request suspends the project for a month. (3) Research projects carry a fixed list of 12 extra safeguards you must apply or justify skipping. (4) Using genetic data for employment or insurance purposes is banned outright. (5) The privacy regulator cannot fine the State or a commune, so a public body has far less to lose than you do.High confidence
What's about to change?
Two dated changes and several switches already in someone's hand. The dated ones: from 12 January 2027 cloud providers must let customers move away with no exit or transfer fees at all, and Luxembourg's new cybersecurity law, in force since 10 May 2026, is still being filled in with guidance and templates. The switches to watch: the European approval of United States transfers is under formal challenge, and the 6-month duty on telecoms firms to keep call records sits uneasily with European court rulings and could be struck at any time.Medium confidence
