LuxembourgChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: For most businesses, data can leave Luxembourg on the same terms as anywhere else in the European Union: you need the right paperwork, not a local data centre. Finance is the exception, and finance is most of the economy here. Banks and insurers are bound by a secrecy duty that is a crime to break, and a bank that runs its accounts abroad must still keep a daily backup inside Europe.
The catch: The relaxed general answer stops the moment you touch banking, insurance or investment funds. There, three things bite: breaking client secrecy is a criminal offence, not a fine; you may only send client information to a supplier abroad if the client has accepted the outsourcing, the type of information and the country the supplier sits in; and if a bank's accounting system is hosted outside Luxembourg it must still hold a full end-of-day backup on premises inside the European Economic Area. Telecoms firms face a separate 6-month duty to keep call and location records.
Does this apply to me?: Yes. If you sell to people in Luxembourg or watch what they do online, the European privacy rules reach you even with no office here. There is no revenue or headcount threshold to hide under. A company with no base anywhere in Europe must appoint a representative in Europe, though it does not have to be in Luxembourg. The extra Luxembourg-only duties in the national law mostly apply to organisations that are actually set up here.High confidence
Can the data leave the country?: In general, yes, with paperwork. Luxembourg has no national law telling ordinary companies to keep data in the country, and European law actually forbids member states from forcing non-personal data to stay put except on public-security grounds. But this is a banking and fund centre, and the finance rules change the answer. A bank or insurer may only hand client information to a supplier abroad if the client has been told and has accepted which country that supplier is in. And a bank whose accounting system sits outside Luxembourg must still keep a full daily backup somewhere inside the European Economic Area.High confidence
What do I have to do to send it abroad?: The model is a European approved-list. Sending personal data outside Europe is barred unless the destination is on the European Commission's approved list, or you put an approved safeguard in place first. The list is real and populated. Luxembourg adds no national permit and the regulator does not pre-approve ordinary transfers. In finance, though, you also need the client's acceptance of the destination country before their information moves.High confidence
Who enforces this — and are they actually working?: Yes, the regulators here really work. The privacy regulator is the National Commission for Data Protection, known as the CNPD. It is staffed, it publishes decisions, and in 2025 it handled 846 complaints, 425 breach reports and 59 investigations. It issued the largest privacy fine ever recorded in Europe, against Amazon in 2021. The financial regulator and the insurance regulator are heavyweight supervisors in their own right, and since May 2026 the telecoms regulator also runs the national cybersecurity regime.High confidence
How long must I keep it, and when must I delete it?: There is a floor and a ceiling, and they collide often. You must keep anti-money-laundering records for 5 years after the relationship ends, patient files for at least 10 years after care ends, and telephone and internet connection records for 6 months. In the other direction, European privacy law says delete personal data once you no longer need it, and the anti-money-laundering law says delete it when the 5 years are up unless another law makes you keep it longer. That last sentence is how Luxembourg resolves the clash: the longest specific legal duty wins, and after that you must actually erase.High confidence
What happens when something goes wrong?: Count four clocks, because they overlap and they start at different moments. Privacy breach: 72 hours to tell the privacy regulator. Telephone and internet providers: 24 hours to report a personal data breach. Cybersecurity incidents at important companies: an early warning in 24 hours, a fuller report in 72 hours, and a final report a month later. Banks and insurers have their own European reporting on top. The trap is that one incident can start all of them at once, on different teams, with different forms.High confidence
What's the trap?: Five things that are not in any summary. (1) Breaking bank or insurance client secrecy is a crime, not a fine, and it survives the end of the job. (2) Your works council can freeze an employee-monitoring project: staff have 15 days to ask the privacy regulator for an opinion, and that request suspends the project for a month. (3) Research projects carry a fixed list of 12 extra safeguards you must apply or justify skipping. (4) Using genetic data for employment or insurance purposes is banned outright. (5) The privacy regulator cannot fine the State or a commune, so a public body has far less to lose than you do.High confidence
What's about to change?: Two dated changes and several switches already in someone's hand. The dated ones: from 12 January 2027 cloud providers must let customers move away with no exit or transfer fees at all, and Luxembourg's new cybersecurity law, in force since 10 May 2026, is still being filled in with guidance and templates. The switches to watch: the European approval of United States transfers is under formal challenge, and the 6-month duty on telecoms firms to keep call records sits uneasily with European court rulings and could be struck at any time.Medium confidence

GermanyChecked 18 August 2026

Yes, with paperworkWork: HighEnforcement: Active

In one paragraph: Contrary to widespread belief, neither Europe nor Germany requires personal data to be stored in Europe. What the law requires is a valid legal instrument before data leaves — an official decision that the destination is safe enough, or a standard contract, plus a documented risk assessment. Germany then adds its own layer on top, and one genuine hard wall: health and social data may only be processed in the cloud within Europe, by a provider holding a specific German security certificate.
The catch: 'Germany doesn't require local storage' is true right up until you sell to a hospital, a health insurer, a doctor, a lawyer or a tax adviser. In health and social care it is simply false, and for the professional-secrecy trades a standard data processing agreement is not enough and getting it wrong is a criminal matter.
Does this apply to me?: Yes, it reaches you with no office in Germany. Europe's privacy law applies to any organisation anywhere that offers goods or services to people in Europe or monitors their behaviour. If you have no European establishment you must also appoint a representative inside Europe.High confidence
Can the data leave the country?: Yes — with paperwork. This is the single most misunderstood point in the field. European law does not say where data must sit; it says what you must have in place before it leaves Europe. Storage location is a risk factor in that assessment, never a prohibition. For non-personal data, Europe goes further and actually forbids member states from imposing storage-location rules.High confidence
What do I have to do to send it abroad?: One of three routes. Best case, the destination is on Europe's official 'adequate' list and you need nothing extra — currently 17 entries including the UK, Japan, South Korea, Switzerland, Canada for commercial bodies, Brazil since January 2026, and the United States but only for companies self-certified under the EU-US Data Privacy Framework. Otherwise you sign Europe's standard contract clauses, or get group-wide internal rules approved. In either of those two cases you must also document an assessment of whether the destination country's surveillance laws undermine the protection.High confidence
Who enforces this — and are they actually working?: Eighteen separate authorities, and for a private company it is almost never the federal one. Each of the 16 states has its own regulator, and you answer to the one where your German office is. The federal regulator handles government bodies plus telecoms and postal operators. Bavaria splits it further, with different bodies for private and public sector. If you operate across Europe, a separate rule lets you deal mainly with the regulator where your main European establishment sits.High confidence
How long must I keep it, and when must I delete it?: Business records have a floor: accounting vouchers must be kept 8 years (cut from 10 with effect from 2025, and from 2026 for banks and insurers), the annual accounts and trading books still 10 years, and business correspondence 6 years. Privacy law pushes the other way — don't keep personal data longer than you need it. Where the two collide, German law has an elegant answer: you restrict processing of the data instead of deleting it.High confidence
What happens when something goes wrong?: 72 hours to tell your state regulator about a personal data breach, and without undue delay to tell affected people where the risk to them is high. Separately, since December 2025 Germany's cybersecurity law adds its own clocks for around 29,500 in-scope companies: a first warning within 24 hours, an update at 72 hours, and a full report within a month. Financial firms follow a separate European regime instead.High confidence
What's the trap?: Four. (1) Health and social data really does have to stay in Europe, with a specific German security certificate — the general 'no localisation' answer is wrong here. (2) For doctors, lawyers, tax advisers and notaries, a standard data processing agreement is NOT enough: you need explicit secrecy undertakings flowed down to every subcontractor, and breach is a criminal offence, not a fine. (3) Germany still requires a data protection officer at just 20 employees involved in data processing — far stricter than European law, and still in force despite a government promise to scrap it by the end of 2026. (4) The German rule people cite for employee data was effectively struck down by Europe's top court in 2023 but never removed from the statute book, so citing it as your legal basis is a mistake.High confidence
What's about to change?: Two hard dates and one live risk. From 12 January 2027 every cloud provider must drop switching and data egress fees to zero — renegotiate contracts now. By 31 December 2026 Germany's banking IT rulebook is fully withdrawn in favour of the European financial regime. The live risk is the US arrangement: Europe's data protection board formally asked the Commission on 31 July 2026 to review whether it is still valid, and a separate court appeal is pending. If it falls, thousands of transfers move to standard contracts overnight.High confidence
