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

MexicoChecked 18 August 2026

Depends on your industryWork: MediumEnforcement: Waking up

In one paragraph: Mexico's general privacy law does not care where you store data. There is no approved-country list, no standard contract to sign and no permission to ask for. You need the right wording in your privacy notice and, usually, the person's consent. The rules that actually pin data to Mexico live in banking, money-laundering and tax law, not in the privacy law.
The catch: The relaxed headline stops the moment you are a bank, a stockbroker, a crowdfunding platform, an insurer or a phone company. Banks need written permission from the banking regulator before any processing happens abroad. Separately, anti-money-laundering law and tax law require many ordinary businesses to keep their records at a Mexican address for ten and five years. Those rules bind companies that have never read a privacy law.
Does this apply to me?: Probably yes, but Mexico is unusually vague about it. The privacy law says only that it applies across Mexican territory. It does not spell out when it reaches a company based abroad. The old rulebook did say the law caught a foreign company that used equipment or systems located in Mexico, and let that company appoint a local representative instead of opening an office. That old rulebook belonged to a law that was scrapped in March 2025, so its status today is genuinely unclear. There is no revenue or headcount threshold to fall below.Medium confidence
Can the data leave the country?: Under the general privacy law, yes, and with very little paperwork. Mexico has no list of approved countries and no list of banned ones. Sending data to a company abroad is treated exactly like sending it to a company down the road: say so in your privacy notice, get the person's consent unless one of seven exceptions applies, and pass the privacy notice on to whoever receives the data. Handing data to your own supplier who only follows your instructions is not even counted as a transfer. Five sectors override this, and in three of them the override is severe.High confidence
What do I have to do to send it abroad?: Nothing needs approval and no list exists in either direction. The model is simply unrestricted: any destination is allowed. What you need is a privacy notice that names the transfer and carries a clause where the person accepts or refuses it, plus that person's consent unless one of seven legal exceptions covers you. Because there is no list to populate, the government cannot make this stricter by adding a country. It would take a new law or a new regulation.High confidence
Who enforces this — and are they actually working?: Mexico abolished its independent privacy regulator. The National Institute for Transparency, Access to Information and Data Protection was wound up in March 2025 and its staff, files and cases were moved into a government ministry, the Anti-Corruption and Good Government Ministry. So the referee is now part of the government rather than independent of it. The ministry is staffed, but the law says the detailed procedure for complaints, inspections and fines will be set out in a regulation, and that regulation still has not been published. Financial regulators, by contrast, are visibly active and update their rulebooks almost monthly.Medium confidence
How long must I keep it, and when must I delete it?: There is no single retention period. The privacy law says delete data once it is no longer needed, after a blocking period equal to the time limit for suing over the relationship. One hard ceiling is written into the law: information about someone breaking a contract must be erased six years after the default. The floors are longer and come from other laws. Tax records must be kept five years and their supporting documents must be available at your Mexican tax address. Anti-money-laundering records must be kept ten years at an address you register with the Finance Ministry. Phone companies keep call and location records for two years. Where a floor and a ceiling clash, the floor wins, because the privacy law lets you keep data to meet a legal duty.High confidence
What happens when something goes wrong?: There are at least three clocks and they do not agree. Under the general privacy law you must tell the affected people immediately if a breach significantly harms their money or their reputation, and there is no duty to tell the regulator at all. Banks face a much tighter set: tell the banking regulator immediately, tell affected customers within forty-eight hours, file a full report within five working days, and send a remediation plan within fifteen working days of the incident ending. Phone companies must hand requested records to the authorities within twenty-four hours and keep a team available every hour of every day. Mexico has no general cyber-incident reporting law that catches everyone.High confidence
What's the trap?: Five things catch people out. Every private business in Mexico is now legally required to ask customers for their national population ID number. Anti-money-laundering rules force many ordinary businesses to keep ten years of records at a Mexican address, which quietly rules out a pure foreign cloud setup. Mishandling data can put a person in prison, not just cost a company money. Banks must get written permission before any processing happens abroad, and that includes routine cloud hosting. And the rulebook the privacy law keeps pointing at does not exist.High confidence
What's about to change?: The biggest thing coming is a regulation that is already overdue. The privacy law repeatedly says a rulebook will set the deadlines for complaints, inspections and fines, and the government missed its own June 2025 deadline to publish it. When it lands it could change how enforcement works overnight, with no consultation. Health law was changed in January 2026 to put telehealth on a statutory footing, and the biometric national ID is still being rolled out. The dangerous powers are the ones the government already holds rather than any bill in parliament.Medium confidence
