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

BulgariaChecked 18 August 2026

Depends on your industryWork: MediumEnforcement: Active

In one paragraph: Bulgaria is an ordinary European Union country for data. Personal data can leave, as long as you use one of the standard European transfer tools. There is no general rule forcing data to stay in Bulgaria. But online gambling is a hard exception: a control server must physically sit on Bulgarian soil. Bulgaria switched to the euro on 1 January 2026, so all fines are now in euro.
The catch: The relaxed headline stops being true in two places. First, online gambling: an operator licensed in Bulgaria must keep a control local server on Bulgarian territory and stream live game data to the tax authority's server. Second, telecoms: operators must build and pay for interception equipment wired into two Bulgarian state agencies, which cannot be run from abroad. Mapping and aerial survey work also needs clearance from five Bulgarian ministries and agencies before you may even collect the data.
Does this apply to me?: Yes, it can reach you with no office in Bulgaria. The European Union's privacy rulebook applies to anyone who offers goods or services to people in Europe or watches what they do online. Bulgaria's own Personal Data Protection Act sits on top of that and adds extra local duties. There is no revenue or headcount threshold, and no Bulgaria-specific representative: the European-wide requirement to name a representative in Europe is the only one, and it can be in any European country.High confidence
Can the data leave the country?: In general, yes. Bulgaria has no law telling ordinary businesses to keep personal data inside the country. Data moves freely to the rest of Europe, to Switzerland, and to countries Europe has approved; anywhere else needs a standard contract or a similar tool. Two industries break that pattern. Online gambling operators must keep a control server physically in Bulgaria. Telecoms operators must build interception equipment that plugs into Bulgarian state agencies, which cannot sit abroad.High confidence
What do I have to do to send it abroad?: Bulgaria uses Europe's system, not its own. There is no Bulgarian list of banned countries and no Bulgarian permit to apply for. If the destination is inside Europe, the wider European Economic Area or Switzerland, nothing extra is needed. Otherwise you need either an official European approval of that country, or the standard European contract, or approved group-wide rules. One Bulgarian twist: Bulgarian law explicitly puts Switzerland on the same footing as a European Union country.High confidence
Who enforces this — and are they actually working?: The Commission for Personal Data Protection is the main regulator. It is real, staffed and it does issue formal decisions, including ones published across Europe. But it is not a heavy hitter. In a Europe-wide check on deletion rights reported in February 2026, it contacted twenty-three organisations, opened no formal investigations, imposed no penalties, and said it did not plan to. A separate inspectorate polices the courts and prosecutors. Cybersecurity has its own separate regulators.Medium confidence
How long must I keep it, and when must I delete it?: Bulgaria has strong minimum-keeping rules and a few sharp delete-by rules. You must keep payroll records for fifty years, accounting books and financial statements for ten years, and other accounting papers for three years. Telecoms firms keep connection records for six months. Going the other way, job applicants' data must be deleted within six months unless they agree otherwise, and data you were given with no legal basis must be returned or destroyed within one month.High confidence
What happens when something goes wrong?: There are at least three clocks and they do not agree. A personal data breach must reach the privacy regulator within seventy-two hours. Under the cybersecurity law rewritten in February 2026, an early warning must reach the response team within twenty-four hours and a fuller report within seventy-two hours. Trust service providers get twenty-four hours for that fuller report. Financial firms answer to the separate European financial-resilience rules on top.High confidence
What's the trap?: Five things bite people in Bulgaria. You may not photocopy someone's identity card, driving licence or residence permit unless a law lets you. Children need a parent's consent up to age fourteen, not sixteen. Job applicant files must go within six months. Your accounting software must be able to output in Bulgarian. And one clause of the privacy law was struck down by the Constitutional Court in 2019 but is still printed in the statute.High confidence
What's about to change?: Two dated changes are already fixed. From 12 January 2027 every cloud provider must let customers move their data out for free. Bulgaria's new cybersecurity duties started on 13 February 2026 and enforcement is only now warming up. The biggest live risk is not Bulgarian at all: Europe's approval of United States data transfers is being challenged, and Europe's own privacy board asked the Commission on 31 July 2026 to re-examine it.High confidence
