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

EstoniaChecked 18 August 2026
Depends on your industryWork: MediumEnforcement: Active
In one paragraph
Estonia has no general rule forcing data to stay in the country, and it adds very little on top of the European privacy rules. Two industries are the exception. Phone and internet companies must keep connection records inside the European Union, with some records physically in Estonia. Online gambling firms may only run their game server from a short list of approved countries. The regulator works, but its fines are small.
The catch
The relaxed headline stops being true the moment you are a telecoms operator, an online gambling operator, a health care provider or a public body. Telecoms connection records may not leave the European Union at all and certain police-request records must sit on Estonian soil. Gambling servers are limited to an approved list of countries. Health records carry a 30-year minimum keep-time. Public bodies must run the Estonian national security standard and exchange data through the state's own data layer.
Does this apply to me?
Yes, it reaches you even with no office in Estonia. Estonia does not write its own reach test — it uses the European Union's. If you offer goods or services to people in Estonia, or track what they do online, the European privacy rules apply and Estonia's regulator can act against you. There is no size or revenue threshold to fall below. A company with no branch anywhere in Europe normally has to name a written representative inside Europe.High confidence
Can the data leave the country?
In general, yes. Estonia has no law telling companies to keep personal data in Estonia, and European law actually forbids member states from imposing one on non-personal data. Two industries break that headline. Phone and internet companies must keep their call and connection records inside the European Union, and certain police-request records must stay physically in Estonia. Online gambling companies may only place their game server in Estonia, in a country that has signed the cybercrime treaty, or in a country whose regulator has a cooperation deal with the Estonian Tax and Customs Board.High confidence
What do I have to do to send it abroad?
For the normal routes you file nothing with the Estonian regulator. If the destination country has been officially approved by the European Commission, you simply send the data. If it has not, you sign the European Commission's standard contract with the recipient and run a risk check on the destination first. Only two routes need Estonia's regulator to sign off: group-wide internal rules where the parent company is in Estonia, and a one-off contract you wrote yourself.High confidence
Who enforces this — and are they actually working?
The Data Protection Inspectorate, and it is genuinely working. It has 34 posts, a director general in her second term since May 2024, and it publishes its orders. In 2025 it took in 1,568 complaints, issued 13 orders and imposed 5 penalties. But note the shape of the risk: Estonian data protection penalties are handled like minor criminal charges, so they are slow and small, and no Estonian fine has ever approached the European ceilings. Cyber rules are enforced separately by the Information System Authority, which also publishes orders — the most recent on 5 June 2026.High confidence
How long must I keep it, and when must I delete it?
Estonia has some of the longest minimum keep-times in Europe. Health records must be kept for 30 years. Anti-money-laundering paperwork for 5 years after the customer leaves. Phone and internet connection records for 1 year, and the police request logs behind them for 5 years. Gambling records for 5 years. Going the other way, a dead person's data stays protected for 10 years after death, or 20 years if they died as a child, and a missed payment may only be reported to credit agencies between 30 days and 5 years after it happened.High confidence
What happens when something goes wrong?
Count three clocks, not one. If personal data leaks, you have 72 hours to tell the Data Protection Inspectorate, and you must tell the affected people without delay if the risk to them is high. If you run an important or essential service, you have only 24 HOURS to send a first cyber-incident warning to the Information System Authority, then 72 hours for a fuller report, then one month for a final report. Trust service providers such as e-signature and certificate companies must send the fuller report inside 24 hours too. Missing the cyber deadline is punished separately from missing the privacy one.High confidence
What's the trap?
Six things that are not in the summary. (1) A child in Estonia is anyone under 13 for online services, not 16 as in much of Europe, so a consent flow tuned to Germany will over-block Estonian teenagers. (2) A dead person's data stays protected for 10 years after death, 20 if they died as a child, and the heirs control it. (3) Research on Estonians must be stripped of names BEFORE the data are handed over, an ethics committee must sign off sensitive projects, and you must name the individual who holds the key. (4) Data protection fines are handled like minor criminal charges, which makes them small but also drags a named human being into the process. (5) Since 1 January 2025 the regulator itself can sue you in court on behalf of a whole group of affected people. (6) Under the cyber law a named board member is personally responsible for security and must attend training.High confidence
What's about to change?
One near-term date stands out. Estonia's official gazette marks its own current texts of the privacy, public information, cybersecurity, telecoms, emergency, health services, health insurance and social welfare acts as valid only until 30 September 2026, so a further change starts on 1 October 2026. We could not identify the amending law, so treat that date as a hard diary entry. Beyond it, the cyber rules phase in: registration was due by 1 April 2026 and full compliance is due by 1 January 2029. From 12 January 2027 European rules make cloud switching and data export charges free.Medium confidence
