SwedenChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: Sweden has no general law forcing data to stay in the country. Personal data leaves under the ordinary European rules. But four walls override that: gambling systems must sit in Sweden, telecoms records kept for the police may never leave the European Union, classified material needs a state-to-state deal, and accounting books stay in Sweden unless you tell the tax agency.
The catch: The relaxed headline stops being true the moment you touch online gambling, telecoms records held for law enforcement, security-sensitive activity, detailed maps and sea-depth data, a public authority's secret files, or a Swedish company's accounting books. In those six areas Sweden is far stricter than its reputation suggests, and two of them carry prison sentences rather than fines.
Does this apply to me?: Yes. Sweden applies the European privacy rules, so a company anywhere in the world is caught if it offers goods or services to people in Sweden or watches what they do. There is no size or revenue floor to duck under. Sweden's own top-up law adds Swedish-only duties on top, and those apply to anyone processing data under Swedish law, not just Swedish companies. If you are outside Europe and caught, you normally have to name a representative inside Europe.High confidence
Can the data leave the country?: In general, yes. Sweden has no law that says personal data must physically stay in Sweden, and European law actually bans Sweden from imposing storage rules on non-personal data except for national security reasons. The exceptions are what matter. Online gambling systems must be placed in Sweden. Telephone and internet records that operators keep for the police may not be stored outside the European Union. Security-classified material cannot go to a foreign body without a government-to-government agreement. And a Swedish company's accounting records must be kept in Sweden unless it tells the tax agency where they are instead.High confidence
What do I have to do to send it abroad?: Sweden adds nothing of its own here — it uses the European toolkit unchanged. The model is an allowlist of approved destinations, and that list is well populated: the United Kingdom, Switzerland, Japan, South Korea, Canada, Brazil and about a dozen others are approved. For everywhere else you sign the European Commission's standard contract, or use group-wide rules approved by a regulator, and you write down why you think the data will still be safe. United States transfers work only if the receiving company has signed up to the European Union–United States Data Privacy Framework, and that arrangement is under legal pressure.High confidence
Who enforces this — and are they actually working?: The main privacy regulator is the Swedish Authority for Privacy Protection, and it is fully staffed and working. It published supervisory decisions in May, June and July 2026, including a reprimand to a large security company over filming its own staff, and in June 2026 it was also made Sweden's market surveillance authority for the European artificial intelligence rules. Other regulators matter just as much in their own lanes: the financial supervisor, the telecoms and post authority, the gambling authority, the Security Service and the Armed Forces.High confidence
How long must I keep it, and when must I delete it?: Sweden has a hard floor and a soft ceiling, and they pull in opposite directions. You must keep company accounting records for seven years after the end of the year they relate to, and patient records for at least ten years after the last entry. Against that, European privacy law says you must delete personal data once you no longer need it. Sweden resolves the clash the same way most of Europe does: a specific legal duty to keep something beats the general duty to delete it, so you keep it, lock it down and use it for nothing else.High confidence
What happens when something goes wrong?: Count at least three clocks, and they do not agree. For a personal data breach you have 72 hours to tell the privacy regulator, and you must tell the affected people without undue delay if the risk to them is high. Since 15 January 2026, organisations in important sectors must send an early warning to their cybersecurity supervisor within 24 hours of noticing a significant incident, then a fuller report within 72 hours — but trust service providers get only 24 hours for the full report. Financial firms have a fourth clock under the European digital resilience rules. The 24-hour warning is the one that catches people out.High confidence
What's the trap?: Five things that are not in any summary. One: a child can consent from age 13 in Sweden, the youngest age Europe allows, so a global default of 16 is wrong here. Two: you may only use a person's Swedish identity number without their consent when it is clearly justified — a Swedish-only rule with no European equivalent. Three: anything you send to a Swedish public authority can become a public document that any member of the public, including a competitor or a journalist, can demand a copy of. Four: giving a supplier access to a public authority's secret files is allowed only for purely technical processing or storage, and only if it is not inappropriate in the circumstances — the ordinary supplier contract is not enough. Five: mapping and sea-depth data is criminal law, not paperwork — spreading it without a permit can mean up to a year in prison.High confidence
What's about to change?: Two dated items. On 1 January 2027 a new law on the resilience of critical operators is proposed to start, covering eleven sectors and adding another 24-hour incident report. Also on 12 January 2027, European rules make it illegal for cloud providers to charge you to move your data out. Watch the government's national cloud policy, adopted on 28 May 2026: today it is only advice with no penalties, but it is the obvious vehicle for a future rule that public bodies must use European providers.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
