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

JapanChecked 18 August 2026
Yes, with paperworkWork: MediumEnforcement: Active
In one paragraph
Japan lets personal data leave the country, but you need paperwork. Only Europe and the United Kingdom are pre-approved. For anywhere else you either sign a contract that binds the recipient to Japanese-standard protection, or you get the person's consent after telling them which country the data goes to. There is no general rule forcing data to stay in Japan.
The catch
Two things break the calm headline. If you sell to the Japanese government, the data must physically sit in Japanese data centres. And if you run a website, an app or any online service used from Japan, the telecoms law reaches you even with no office here, requires a representative in Japan, and makes leaking a communication a criminal offence rather than a fine.
Does this apply to me?
Yes. Japan's privacy law reaches a foreign company with no office and no staff in Japan, as long as it handles the personal information of people in Japan while supplying them goods or services. There is no size, revenue or headcount threshold to fall below. Unlike Europe, the privacy law does not make you appoint a representative in Japan — but the telecoms law does, if your service counts as a telecommunications service.High confidence
Can the data leave the country?
Yes, with paperwork. Japan's general rating is conditional: personal data may go abroad once you have one of three things in place. There is no across-the-board law keeping data in Japan, and no financial, insurance, securities or health localisation rule of the kind India or China have — we searched for one and did not find it. The real wall is government work: anything running on the national Government Cloud must sit in data centres inside Japan.High confidence
What do I have to do to send it abroad?
The model is an allowlist, and the list has exactly two entries: the European Union and the United Kingdom. Send data there and it is treated almost like a domestic transfer. For every other destination you need one of two things instead. Either the recipient is contractually bound to protect the data to Japanese standards and you keep checking that it does, or you get the person's consent after first telling them the destination country, what its privacy law is like, and what the recipient will do to protect the data.High confidence
Who enforces this — and are they actually working?
The Personal Information Protection Commission, and it is genuinely working. It has a chair, eight commissioners and a staff ceiling of 231 people. In the year to March 2025 it handled just over 19,000 breach reports, gave 395 pieces of formal guidance and made one recommendation. In the first six months of the following year it sharpened up: two recommendations and its first emergency order, against a company misusing personal information. What it cannot do yet is fine you — Japan has no administrative money penalty for privacy breaches until the 2026 amendment starts.High confidence
How long must I keep it, and when must I delete it?
The floor is firm and the ceiling is soft. Tax law makes you keep books and records for seven years, stretching to ten if you carry a loss forward. Company accounting books run ten years. Against that, the privacy law only asks you to try to delete personal data once you no longer need it — it is a best-efforts duty, not a hard deadline. So when the two collide, the keep-it rule wins in practice.Medium confidence
What happens when something goes wrong?
Count three clocks. For a personal data breach you file a first report to the privacy regulator within three to five days of finding out, and a full report within 30 days — 60 days if someone did it on purpose. You must also tell the people affected. Critical infrastructure operators have a separate cyber incident duty with a report to the government within 30 days. Telecoms operators report leaks of communications to the communications ministry on their own timetable.High confidence
What's the trap?
Five. (1) Putting data on a foreign server is often not a 'transfer' at all — if the provider is contractually barred from touching it — but you then have to work out that country's privacy law and publish the country's name to your users. Most people miss this. (2) The privacy law has no fines: the sanctions are criminal, and a company can be fined about $650,000 for a staff member stealing a customer database. (3) Leaking a communication is a crime punishable with prison, and telecoms staff face a longer term than outsiders. (4) The telecoms rules catch ordinary websites and apps, not just phone companies, and reach foreign operators with no office in Japan. (5) Consent to send data 'overseas' is not valid — you have to name the country.High confidence
What's about to change?
The big one has already passed. On 17 July 2026 Japan published a large amendment to its privacy law. It introduces the country's first money penalty for privacy breaches, sets 16 as the age below which a guardian must be involved, adds rules for face and other biometric data, and raises the criminal penalties. It is not in force yet: the government has up to two years to switch it on by order, and no date has been announced. The other thing to watch is the new cyber defence law, which is being switched on in stages through 2027.High confidence
