GermanyChecked 18 August 2026

Yes, with paperworkWork: HighEnforcement: Active

In one paragraph: Contrary to widespread belief, neither Europe nor Germany requires personal data to be stored in Europe. What the law requires is a valid legal instrument before data leaves — an official decision that the destination is safe enough, or a standard contract, plus a documented risk assessment. Germany then adds its own layer on top, and one genuine hard wall: health and social data may only be processed in the cloud within Europe, by a provider holding a specific German security certificate.
The catch: 'Germany doesn't require local storage' is true right up until you sell to a hospital, a health insurer, a doctor, a lawyer or a tax adviser. In health and social care it is simply false, and for the professional-secrecy trades a standard data processing agreement is not enough and getting it wrong is a criminal matter.
Does this apply to me?: Yes, it reaches you with no office in Germany. Europe's privacy law applies to any organisation anywhere that offers goods or services to people in Europe or monitors their behaviour. If you have no European establishment you must also appoint a representative inside Europe.High confidence
Can the data leave the country?: Yes — with paperwork. This is the single most misunderstood point in the field. European law does not say where data must sit; it says what you must have in place before it leaves Europe. Storage location is a risk factor in that assessment, never a prohibition. For non-personal data, Europe goes further and actually forbids member states from imposing storage-location rules.High confidence
What do I have to do to send it abroad?: One of three routes. Best case, the destination is on Europe's official 'adequate' list and you need nothing extra — currently 17 entries including the UK, Japan, South Korea, Switzerland, Canada for commercial bodies, Brazil since January 2026, and the United States but only for companies self-certified under the EU-US Data Privacy Framework. Otherwise you sign Europe's standard contract clauses, or get group-wide internal rules approved. In either of those two cases you must also document an assessment of whether the destination country's surveillance laws undermine the protection.High confidence
Who enforces this — and are they actually working?: Eighteen separate authorities, and for a private company it is almost never the federal one. Each of the 16 states has its own regulator, and you answer to the one where your German office is. The federal regulator handles government bodies plus telecoms and postal operators. Bavaria splits it further, with different bodies for private and public sector. If you operate across Europe, a separate rule lets you deal mainly with the regulator where your main European establishment sits.High confidence
How long must I keep it, and when must I delete it?: Business records have a floor: accounting vouchers must be kept 8 years (cut from 10 with effect from 2025, and from 2026 for banks and insurers), the annual accounts and trading books still 10 years, and business correspondence 6 years. Privacy law pushes the other way — don't keep personal data longer than you need it. Where the two collide, German law has an elegant answer: you restrict processing of the data instead of deleting it.High confidence
What happens when something goes wrong?: 72 hours to tell your state regulator about a personal data breach, and without undue delay to tell affected people where the risk to them is high. Separately, since December 2025 Germany's cybersecurity law adds its own clocks for around 29,500 in-scope companies: a first warning within 24 hours, an update at 72 hours, and a full report within a month. Financial firms follow a separate European regime instead.High confidence
What's the trap?: Four. (1) Health and social data really does have to stay in Europe, with a specific German security certificate — the general 'no localisation' answer is wrong here. (2) For doctors, lawyers, tax advisers and notaries, a standard data processing agreement is NOT enough: you need explicit secrecy undertakings flowed down to every subcontractor, and breach is a criminal offence, not a fine. (3) Germany still requires a data protection officer at just 20 employees involved in data processing — far stricter than European law, and still in force despite a government promise to scrap it by the end of 2026. (4) The German rule people cite for employee data was effectively struck down by Europe's top court in 2023 but never removed from the statute book, so citing it as your legal basis is a mistake.High confidence
What's about to change?: Two hard dates and one live risk. From 12 January 2027 every cloud provider must drop switching and data egress fees to zero — renegotiate contracts now. By 31 December 2026 Germany's banking IT rulebook is fully withdrawn in favour of the European financial regime. The live risk is the US arrangement: Europe's data protection board formally asked the Commission on 31 July 2026 to review whether it is still valid, and a separate court appeal is pending. If it falls, thousands of transfers move to standard contracts overnight.High confidence

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
