IcelandChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: Iceland follows Europe's privacy rulebook, so personal data can leave the country once the right paperwork is in place. Two local rules surprise people: a company's accounting records must physically be kept in Iceland, and health record systems can only be hosted by a certified provider. The privacy regulator is small but genuinely busy, and it fines public bodies too.
The catch: The relaxed answer is true for personal data only. Iceland's bookkeeping law says a company's books, invoices and receipts must be kept in Iceland for seven years, and only lets you hold them abroad for up to six months — and breaking the bookkeeping law is a crime, not a fine from the privacy regulator. Health record hosting has its own certification wall. Separately, three European laws that people assume apply here — the Data Act, the cybersecurity law known as NIS2, and the Artificial Intelligence Act — have NOT yet been brought into Icelandic law, so the rights and deadlines they create do not exist in Iceland today.
Does this apply to me?: Yes, it reaches you with no office in Iceland. Iceland applies Europe's General Data Protection Regulation through the European Economic Area agreement, so the rules cover any organisation anywhere in the world that offers goods or services to people in Iceland, or that watches what they do. There is no size or revenue threshold to duck under. If your organisation has no establishment anywhere in Europe, you normally have to name a representative inside Europe who people and the regulator can contact.High confidence
Can the data leave the country?: For personal data, yes — it can leave once you have the right paperwork. Two Icelandic rules cut across that headline. First, your company's accounting books, invoices and receipts must be kept in Iceland for seven years; the law only lets you hold them abroad for up to six months. Second, a health record system can sit with an outside host only if that host holds a recognised security certificate and the normal rules for sending data out of Europe are met.Medium confidence
What do I have to do to send it abroad?: You use one of the standard European routes. Send the data to a country Europe has officially approved, or sign the European Commission's standard contract with the recipient, or use group-wide rules a regulator has approved. Narrow one-off exceptions exist, such as the person's explicit consent, but they are not for routine or bulk transfers. One Icelandic wrinkle catches people out: an approval of a foreign country only takes effect in Iceland once the Icelandic minister confirms it and publishes a notice in the official gazette.Medium confidence
Who enforces this — and are they actually working?: Persónuvernd, the Icelandic Data Protection Authority. It is genuinely operational, not a name on paper: it registered 2,124 new cases in 2025 and closed 2,232, it opens its own investigations without waiting for a complaint, and it fines public bodies as well as private companies. It is also small — about 17 staff and a budget of roughly 379 million krónur (about $2.8 million) — and it says in its own annual report that it cannot cover every task the law gives it.High confidence
How long must I keep it, and when must I delete it?: There is a floor and a ceiling, and they point in opposite directions. The floor: accounting books, invoices and receipts must be kept for seven years — and kept in Iceland. The ceiling: under the European rules you must delete personal data once you no longer need it for the purpose you collected it for. When the two clash, the keeping duty wins; a person cannot force you to delete records the bookkeeping and tax law requires you to hold.High confidence
What happens when something goes wrong?: Count at least two clocks, and three if you are a financial firm. You have 72 hours to report a personal data breach to Persónuvernd, and you must tell the people affected without delay where the risk to them is high. Separately, operators of critical services — banks, hospitals, energy, water, transport and digital infrastructure — must alert Iceland's national cyber security team as soon as possible under a 2019 law, and serious breaches of that law can lead to prosecution. Financial firms have a further, tighter reporting duty to the Central Bank under the European operational resilience rules.Medium confidence
What's the trap?: Five things that are not in the summary. (1) A child in Iceland is anyone under 13 for online consent, not 16 as in much of Europe — so a design built for a 16-year-old threshold is wrong here. (2) Your accounting records must sit in Iceland, and bookkeeping offences are criminal: fines, and up to six years in prison for serious cases, investigated by the district prosecutor and the tax investigators, not by the privacy regulator. (3) Public bodies can be fined in Iceland — the law says so expressly, unlike several European countries. (4) Some processing needs a licence from Persónuvernd before you start, which is unusual under the European regime. (5) Three European laws you may assume apply here do not yet: the Data Act, the cybersecurity law known as NIS2, and the Artificial Intelligence Act have not been brought into the European Economic Area agreement.High confidence
What's about to change?: The main thing to watch is not an Icelandic bill but the queue of European laws waiting to be pulled into Icelandic law. The Data Act, the cybersecurity law known as NIS2 and the Artificial Intelligence Act are all still outside the European Economic Area agreement as of 18 August 2026, and each will land when a joint committee decides — with no Icelandic public consultation and often at short notice. The financial resilience regulation already landed this way on 1 July 2025, more than five months after it started applying in the European Union.High confidence

CroatiaChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: Croatia looks like an ordinary European Union country for privacy: data may leave once you have the right paperwork. But its accounting law is stricter than most people expect. A Croatian company's books and receipts may only be kept in Croatia or another European Union country. Public bodies must keep personal-data registers in Croatian data centres. The privacy regulator fines hard.
The catch: The relaxed European headline stops being true in four places. First, accounting: the books and supporting documents of any Croatian company may be kept outside Croatia only in another European Union member state, so a United States or United Kingdom cloud archive of your ledger is not lawful, and no contract or consent fixes it. Second, the public sector: since May 2025 state registers containing personal data must sit in data centres on Croatian soil, and state bodies must use the government's own Shared Services Centre. Third, health: health data must be processed inside Croatia's national health information infrastructure and exchanged through the central health system. Fourth, aerial imagery: you need one permission to photograph Croatia from the air and a second permission to use the pictures, and the Ministry of Defence screens them first.
Does this apply to me?: Yes. Croatia's rules reach a company with no office in the country. The European Union privacy rulebook applies to anyone who offers goods or services to people in Europe, or who watches what they do online. There is no revenue or headcount threshold. Croatia does not demand its own local representative on top of the Europe-wide one, which you may place in any European country.High confidence
Can the data leave the country?: Mostly yes, but with one nasty exception that catches everybody. Ordinary personal data can go abroad using the standard European transfer tools. Your accounting records cannot: Croatian law allows them to be kept outside Croatia only in another European Union country. Health data, public-sector registers and aerial photographs each have their own separate walls.High confidence
What do I have to do to send it abroad?: For personal data, Croatia uses the European model. Some countries are pre-approved, and everywhere else you need a standard contract or a similar tool plus a risk check. The approved list is real and populated, and includes the United Kingdom, Japan, South Korea and Switzerland. For accounting records the model is different and much blunter: only European Union countries are allowed, and no paperwork buys you more.High confidence
Who enforces this — and are they actually working?: The main regulator is the Personal Data Protection Agency, known as AZOP. It is fully staffed, it hires more people, and it is one of the busiest fining bodies in central Europe for its size. It issued 13 fines totalling about 6.7 million euros (roughly 7.3 million dollars) in 2025, and 38 fines the year before. The cyber regulator, the National Cyber Security Centre, is also up and running.High confidence
How long must I keep it, and when must I delete it?: Croatia has strong minimum keeping periods and a few hard maximums. Ledgers and the documents behind them must be kept at least eleven years; payroll lists six years; the detailed wage and contribution records forever. Medical records run to ten years after the patient dies. Going the other way, camera footage must normally be deleted after six months.High confidence
What happens when something goes wrong?: There are at least two clocks and they run at different speeds. A personal data breach goes to the privacy regulator within 72 hours. A significant cyber incident goes to the cyber authority within 24 hours as an early warning, with a fuller report at 72 hours and a final report within 30 days. One incident can easily trigger both, and the 24-hour clock is the one that catches people out.High confidence
What's the trap?: Five things that are not in the summary. Your ledger cannot live on an American cloud. Children count as adults for online consent at 16, not 13. Using someone's personal data unlawfully is a crime, not just a fine. Genetic test results may never be used to price life insurance. And camera footage in an apartment building needs two thirds of the owners to agree.High confidence
What's about to change?: Two Croatian dates matter. Fines under the state information infrastructure law switch on 1 January 2027. Mandatory eInvoicing widens to smaller traders on the same day. Across Europe, cloud switching fees must fall to zero by 12 January 2027. The thing to watch is the challenge to the Europe-United States data deal, which is still valid but under real pressure.Medium confidence
