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

GreeceChecked 18 August 2026
Depends on your industryWork: HighEnforcement: Active
- In one paragraph
- For most businesses Greece is a normal European country: personal data can leave, as long as you use one of the standard European transfer tools. But Greece has two hard walls that Europe does not. Phone and internet connection records must physically sit on machines inside Greece. Online gambling operators must keep their records on a server inside Greece too. The privacy regulator is fully staffed and fining companies today.
- The catch
- The relaxed European headline stops being true the moment you touch three things. Telecoms connection records must be stored on physical media inside Greek territory for twelve months. Online gambling records must sit on a server or safe inside Greece for ten years. And Greek public bodies must run their central systems on the Greek state's own clouds, not on a commercial cloud of their choosing. Outside those three, plus the health and public sectors, Greece imposes no storage-location rule of its own.
- Does this apply to me?
- Yes, it reaches a foreign company with no office in Greece. The European privacy rules apply to anyone anywhere who offers goods or services to people in Greece, or who watches what they do online. The Greek national law adds that it also covers anyone processing data on Greek soil. There is no size or revenue threshold that lets you off. If you have no establishment anywhere in Europe, you must appoint a written representative inside the European Union.High confidence
- Can the data leave the country?
- In general, yes. Greece adds no storage-location rule of its own to the European baseline, so ordinary business data can be sent abroad once you have the right European transfer paperwork. Three industries break that rule completely. Telecoms companies must keep their connection records on machines physically inside Greece. Online gambling operators must keep their records on a server inside Greece. And Greek government bodies must run their main systems on state-operated clouds. Health, banking and insurance have extra hoops but no location rule.High confidence
- What do I have to do to send it abroad?
- You need one of the standard European transfer tools before data leaves Europe. The simplest is sending it to a country the European Commission has already approved. If the destination is not approved, you sign the European Commission's standard contract with the recipient, or use approved group-wide internal rules, and you write down why you think the data will still be safe there. Greece adds no extra permission, filing or fee of its own.High confidence
- Who enforces this — and are they actually working?
- Six bodies, and all six are genuinely working. The Hellenic Data Protection Authority is the main privacy regulator and is issuing numbered decisions and fines every month — its most recent published decisions run to July 2026 and include fines on a bank and an electricity supplier. A separate constitutional authority polices the secrecy of communications. There is also a national cybersecurity authority, a telecoms regulator, the central bank for finance and insurance, and a gambling regulator. This is not a paper regime.High confidence
- How long must I keep it, and when must I delete it?
- Both directions apply, and they collide. Business books must be kept five years. Medical files must be kept ten years in a private practice and twenty years everywhere else. Online gambling records must be kept ten years. Telecoms connection records must be kept exactly twelve months and then automatically deleted. In the other direction, the European rule says you must not keep personal data longer than you need it. When a specific keeping rule and the general deleting rule clash, the specific keeping rule wins.High confidence
- What happens when something goes wrong?
- Count three clocks, not one. If personal data is lost or exposed, you have 72 hours to tell the privacy regulator. If you run important infrastructure, you have only 24 hours to send a first warning to the national cybersecurity authority, then 72 hours for a fuller report and one month for the final one. If you are a phone or internet provider, you have 24 hours to report a personal data breach and a separate duty to tell the communications secrecy authority. Missing the 24-hour clocks is the most common failure.High confidence
- What's the trap?
- Five things that will cost you a weekend. First, a child in Greece can consent to an online service at fifteen, not sixteen — so an age gate built to the European default is set wrong. Second, misusing personal data is a crime here, with prison time, not just a fine. Third, several articles of the Greek privacy law are printed in the statute but the regulator has formally said they must not be applied, because they clash with European law. Fourth, telecoms connection records must physically stay in Greece. Fifth, government bodies cannot simply pick a commercial cloud.High confidence
- What's about to change?
- Three dated changes. Electronic invoicing between businesses became compulsory for large Greek companies on 2 March 2026 and becomes compulsory for everyone else on 1 October 2026. Greece's new artificial intelligence law took effect on 22 July 2026 and forces public bodies to register every artificial intelligence system before switching it on. And from 12 January 2027 European law bans cloud providers from charging you to move your data out.High confidence
