PolandChecked 18 August 2026
Yes, with paperworkWork: HighEnforcement: Active
- In one paragraph
- Poland is a European Union country, so data may leave as long as you use one of the approved European transfer routes. We found no general Polish rule forcing data to stay in the country. The privacy regulator is fully staffed and busy, and it fines government bodies as well as companies. Finance is the sector to watch: the financial supervisor wants cloud data kept in Europe.
- The catch
- True in general, much weaker in finance. Banks, insurers, brokers and payment firms follow a supervisory notice telling them to keep cloud data in European data centres, to put critical firms' data inside Poland first where they can, and to warn the financial supervisor 14 days before any cloud project starts. That notice is a strong recommendation, not a ban — but the supervisor checks it. Classified government information sits outside all of this and is effectively locked inside Poland.
- Does this apply to me?
- Yes, it reaches you with no office in Poland. European privacy law applies to any organisation anywhere that offers goods or services to people in Poland, or that monitors their behaviour. There is no size or revenue threshold. An organisation based outside Europe normally has to name a representative inside Europe. Poland then adds one local step that foreign groups routinely miss: if you must appoint a data protection officer, you have to tell the Polish regulator that person's name and contact details within 14 days of appointing them.High confidence
- Can the data leave the country?
- Yes, with paperwork. Poland has not added a general rule of its own that keeps data inside the country, and European law actually forbids member states from imposing storage-location rules on data that is not about people, except on public-security grounds. We searched for industry walls in banking, payments, insurance, securities, health, telecoms, government cloud, mapping and gambling. The only one we could confirm from an official Polish source is in finance, and it is a firm supervisory recommendation rather than an outright ban.Medium confidence
- What do I have to do to send it abroad?
- Think of it as an approved-routes list. Personal data may go outside Europe if the destination country has been officially approved, or if you sign the standard European contract with the recipient, or if your corporate group has rules approved by a regulator. The approved-country list is real and populated — roughly sixteen countries plus one international organisation. For the United States it only covers companies that have signed up to a specific certification scheme, so you have to check the recipient, not the country.High confidence
- Who enforces this — and are they actually working?
- The Personal Data Protection Office, and it is genuinely working. It is led by Mirosław Wróblewski, it publishes news several times a week, and its public decisions database held 581 decisions when we checked on 18 August 2026, with new ones published through June and July 2026. It fines public bodies too: it penalised the Minister of Justice in June 2026 and a local social welfare centre later the same month. Three other regulators matter — the financial supervisor for banks and insurers, the electronic communications office for telecoms and post, and the Ministry of Digital Affairs for cyber security.High confidence
- How long must I keep it, and when must I delete it?
- There is a ceiling and a floor. The ceiling is European: you may not keep personal data in a form that identifies someone for longer than you need it, and you have to be able to state that period. The floor is Polish: tax, accounting, employment and medical rules force you to keep certain records for years. When the two collide, the specific keeping duty wins for those records and everything else must still be deleted on time. We could not open the official Polish texts for the exact periods on the day we checked, so treat any specific number you read elsewhere as unverified until you see the statute.Medium confidence
- What happens when something goes wrong?
- Count at least two clocks, often three. For a personal data breach you have 72 hours to tell the Polish privacy regulator, and you must warn the people affected without undue delay if the risk to them is high. Separately, Poland rewrote its cyber security law and the new version started on 3 April 2026; if you are on the new register of key or important organisations you also report to the national cyber teams, on a much shorter first clock. Financial firms add a third set of reporting duties to the financial supervisor. The overlap is what breaks people, because the same incident triggers all three with different content and different deadlines.Medium confidence
- What's the trap?
- Five things that are not in the summary. First, appointing a data protection officer is not the end of it — you have 14 days to file that person's name and contact details with the Polish regulator, and foreign groups miss this constantly. Second, the list of Polish organisations that must appoint one is wider than expected and includes the central bank and state research institutes. Third, a brand-new Polish law on data management started in July 2026 and can fine you about two million złoty, roughly $550,000, for sending protected public-sector data to the wrong country. Fourth, the financial supervisor expects to be told 14 days before a cloud project starts and wants critical firms' data inside Poland where possible. Fifth, being a public body is no shield — the regulator fined the Minister of Justice in June 2026.High confidence
- What's about to change?
- Three dated things and one live risk. Poland's new cyber security register is being phased in through 2026: self-registration opened on 7 May 2026, and organisations the ministry enters itself get six months from being served notice to complete their details. On 12 January 2027 European rules ban cloud providers from charging you anything to move your data out. On 2 April 2027 a new European regulation on how privacy regulators run cross-border cases starts to apply, which will change how Polish complaints against foreign companies are handled. The live risk is the European Union–United States data transfer arrangement, which is valid today but being challenged.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
