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

MongoliaChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Waking up

In one paragraph: Mongolia is not an open country for data. As a rule you may not send personal data abroad at all unless the person agrees or a law says you can. On top of that, a 2023 ministry order says that any server handling sensitive data must sit in Mongolia and must be reachable only from inside Mongolia. Sensitive data is defined very widely and includes health records and the content of messages.
The catch: Do not read 'depends on your industry' as 'open in general'. The baseline is already a ban with a consent exception. The hard walls are drawn by data type as much as by industry: health data, biometrics, genetic data, criminal records, digital signature keys and the content of letters, e-mail and messages all fall inside the server-in-Mongolia rule, whatever business you are in. Government bodies, state-owned and state-part-owned companies, and any company running a government service under a law or contract face a second wall over their databases.
Does this apply to me?: Probably not, if you have no presence in Mongolia at all. The privacy law says it governs how people, companies and unincorporated bodies collect, process and use personal data, but it does not say it reaches organisations outside the country. There is no revenue or size threshold, and there is no duty to appoint a local representative. In practice the rules bite through your Mongolian company, your Mongolian server, or your Mongolian licence rather than through long-arm reach.Medium confidence
Can the data leave the country?: Only sometimes, and for a lot of data the answer is a flat no. The general rule is that sending personal data to a person, company or international body abroad is banned unless a law or a treaty allows it, or the person the data is about has agreed. Then a separate ministry order takes health data, biometrics, genetic data, criminal records, digital signature keys and the content of letters, e-mail and messages out of reach entirely: the server has to be in Mongolia and has to be reachable only from Mongolia. Government systems and the country's foundational databases must also stay in Mongolia.High confidence
What do I have to do to send it abroad?: There is no approval process, no standard contract and no list of approved countries. Mongolia works the other way round: the transfer is banned, and the only ways out are a law or treaty that allows it, or the written consent of the person concerned. Consent is not a light-touch tick box. You must name every recipient before you collect the data, you must be able to prove the consent, and the person can withdraw it at any time.High confidence
Who enforces this — and are they actually working?: Nobody owns privacy on its own. The law splits the job three ways: the National Human Rights Commission handles complaints and supervision, the Ministry of Digital Development, Innovation and Communications writes the technical rules and takes cyber incident reports, and other state bodies police their own sectors. The ministry is clearly working: it has issued binding orders and it keeps a live register of 49 licensed information security auditors. What we could not find is any published privacy fine or decision, so treat the privacy side as switched on but not yet biting.Medium confidence
How long must I keep it, and when must I delete it?: Mongolia is unusual: the privacy law tells you when you may delete, not just when you must. You may only erase personal data on four listed grounds, and deleting it on any other ground is forbidden. Pulling the other way, payment businesses must keep their records for at least 15 years, anyone handling sensitive data must keep a history log of every change, deletion and restoration, and organisations running shared information systems must keep activity logs for a period fixed by government rules.High confidence
What happens when something goes wrong?: There are three clocks and none of them is measured in hours. The word the laws use is 'immediately', which they define as the shortest possible time. You tell the affected person immediately if the problem could harm them, you tell the ministry immediately if your system's security failed or you were attacked, and if you run critical national infrastructure you tell the national response centre immediately as well. Once a year, every January, you also send the human rights commission a register of the incidents you had and what you did about them.High confidence
What's the trap?: Five things catch people out. First, fingerprint scanners at work are illegal for private employers: an employer may use other biometrics with the worker's consent, but never fingerprints, and may not pass that biometric data to anyone else. Second, 'sensitive data' includes the content of letters, e-mail and messages, which drags ordinary company mail systems towards the server-in-Mongolia rule. Third, financial and payment data is not classed as sensitive, but a fingerprint or face login for a banking app is, so banks land inside the strict rules by the back door. Fourth, breaking the privacy law can be a crime, not just a fine. Fifth, if you build data storage or a content delivery network inside Mongolia you need a telecoms licence.High confidence
What's about to change?: One big thing is in motion. The government decided on 13 May 2026 to build a legal framework for putting data into economic circulation and reuse, and to prepare for a green, energy-efficient data centre in Mongolia. The ministry is now consulting on a first Data Law. It is a draft, so nothing in it binds anyone yet. The bigger short-term risk is not new legislation at all: the minister can rewrite the server and storage rules by a simple order, without parliament and without consultation.Medium confidence
