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
Hardest industry wall: Telecoms — Elektroonilise side seadus (ESS), § 111-1

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
