SlovakiaChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
- In one paragraph
- Slovakia has no general rule that data must stay in the country. It runs on the European rulebook: send data abroad once you have the right paperwork. Three areas break that rule. Online gambling servers must sit on Slovak soil. The most sensitive government data must stay in a Slovak data centre. And anyone who takes aerial survey pictures of Slovakia must hand a copy to a defence ministry archive.
- The catch
- The easy answer stops being true in three places. First, online gambling: the operator's server must be physically in Slovakia, with no European Economic Area alternative. Second, government cloud: a public body handling the top security category of data may only use a service that stores and processes it inside Slovakia, in a data centre within reach of the Slovak state. Third, mapping: primary aerial survey imagery and published maps must be deposited with Slovak state archives, including one run by the Ministry of Defence. Banking, payments, insurance, securities, health and telecoms have no storage-location rule that we could find.
- Does this apply to me?
- Yes. A company with no office in Slovakia is still caught if it offers goods or services to people in Slovakia, or watches what they do online. There is no minimum size, headcount or revenue below which you are safe. If you have no office anywhere in the European Union, you must name a written representative inside the Union, and you can put that person in any member state where your customers are — it does not have to be Slovakia.High confidence
- Can the data leave the country?
- In general, yes — with the standard European paperwork. Nothing in Slovak law says personal data must be kept in Slovakia, and the law says so almost in as many words: it applies to a Slovak company whether it processes data inside or outside the country. But three specific activities do force data to stay. Online gambling operators must put their server in Slovakia. The top security tier of government data must stay in a Slovak data centre. And aerial survey imagery of Slovakia must be handed to a state archive.High confidence
- What do I have to do to send it abroad?
- Slovakia uses the European model, and it is an allowlist. Data may go to a country the European Commission has approved, or to anywhere else if you sign the Commission's standard contract, use approved group-wide rules, or fit one of a few narrow exceptions. The approved list is real and populated — it includes the United Kingdom, Switzerland, Japan, South Korea, Canada for commercial bodies, and the United States only for companies signed up to the transatlantic framework. Slovakia adds nothing of its own on top.High confidence
- Who enforces this — and are they actually working?
- The Office for Personal Data Protection of the Slovak Republic. It is real, staffed and busy. In 2025 it issued 542 final fines totalling about 468,000 euros (roughly $510,000) and actually collected about 411,000 euros of that — a very high number of fines but a very small average, about 860 euros each. It has around 60 staff and got 20 extra posts in 2025. Cybersecurity incidents go to a separate body, the National Security Authority.High confidence
- How long must I keep it, and when must I delete it?
- There is no single retention rule. The general privacy rule is to delete when you no longer need the data. Against that sit long minimum-keeping duties: ten years for accounts and financial statements, and up to one hundred years after death for entries in the national health registers. Telecom companies keep far less than most people assume — Slovakia scrapped blanket call-record retention after its Constitutional Court struck it down, so operators only retain what a court order covers.High confidence
- What happens when something goes wrong?
- There are two clocks and they are different. A personal data breach goes to the privacy authority within 72 hours of you becoming aware of it, and to the affected people without undue delay if the risk to them is high. A cybersecurity incident at a regulated organisation goes to the National Security Authority twice: a first warning within 24 hours, then a fuller report within 72 hours. If you are both, you file both, to two different bodies.High confidence
- What's the trap?
- Five things that are not in the summary. Public bodies can be fined the full amount, with no discount. Mishandling personal data you got through your job is a crime, not just a fine. The age of consent for online services is 16, not 13. The rule on dead people's data changed today. And the gambling server rule has no European workaround.High confidence
- What's about to change?
- The whole national privacy law is being replaced by two new laws — one general, one for police and courts — but they are still bills and have no legal effect. Act 18/2018 was amended today, 18 August 2026, mostly to remove dead people from its scope. Public bodies face a bigger data-registration duty from 1 January 2027, and all cloud switching and data export fees across Europe must drop to zero by 12 January 2027.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
