SpainChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Aggressive

In one paragraph: Spain follows the normal European rule: personal data may leave the country once you have the right paperwork in place. But four named categories of data held by the Spanish state must physically stay inside the European Union, and may only travel further to a country Europe has officially approved. Spain's privacy regulator is one of the busiest in the world.
The catch: The relaxed headline stops being true the moment you touch the electoral roll, town-hall population registers, Spanish tax records or data about users of the Spanish national health service. For those four things a standard European transfer contract is not enough and never will be — the law allows only officially approved destinations. Online gambling, telecoms and any system sold to the Spanish public sector carry their own separate rules.
Does this apply to me?: Yes. A company with no office in Spain is still caught if it offers goods or services to people in Spain or watches what they do online. There is no size or revenue threshold to hide under. If you have no base anywhere in Europe you must appoint a written representative inside Europe, and Spain's regulator will happily deal with that representative instead of you.High confidence
Can the data leave the country?: For most businesses, yes, with paperwork — the ordinary European rules apply and nothing in Spanish law says data must sit on Spanish soil. The exception is sharp. If the data is the electoral roll, a town-hall population register, Spanish tax records, or information about users of the Spanish national health service, the computers holding it must be inside the European Union, and that data may only go outside Europe to a country Europe has officially approved. A standard European transfer contract does not work for those four things.High confidence
What do I have to do to send it abroad?: The model is an approved-list one, run at European level, not by Spain. You may send data outside Europe if the destination country is on Europe's approved list, or if you sign Europe's standard contract, or if your corporate group has approved internal rules. The list is real and populated. Spain adds one twist: if you want to use a home-made contract instead of the standard one, you must get written permission from the Spanish regulator first.High confidence
Who enforces this — and are they actually working?: The Spanish Data Protection Agency, and it is very much awake. Its public decision database held 46,925 decisions when we checked on 18 August 2026, with rulings signed as recently as 12 August 2026. Three regional authorities also enforce, covering public bodies in Catalonia, the Basque Country and Andalusia. Spain's artificial intelligence supervisor is now operating too and met the privacy agency in July 2026 to divide up the work.High confidence
How long must I keep it, and when must I delete it?: Both directions, and they collide. The longest floor is money laundering records: ten years, and the same law then orders you to destroy them. Business books run six years, clinical records at least five years from the end of each course of treatment, phone and internet connection records twelve months, and the taxman can come back four years. In the other direction Spain does something unusual: when someone asks you to delete their data you must not actually delete it, you must lock it away.High confidence
What happens when something goes wrong?: Count three clocks, not one. Everyone has 72 hours to tell the privacy regulator about a personal data breach. Phone and internet providers have only 24 hours under a separate European rule. And if you run something the state treats as an essential service, the cyber clock says report immediately, then send an update within 24 to 48 hours if the incident is critical, or 72 hours if it is very serious, with a final report 20 or 40 days later.High confidence
What's the trap?: Five things that ruin weekends. One: a child can consent at fourteen in Spain, not sixteen, so your global age gate is probably wrong here. Two: 'delete my data' legally means 'lock my data away', so a hard-delete pipeline breaks the law. Three: Spain forces far more organisations to appoint a data protection officer than Europe does, including every school, university, bank, insurer, energy supplier and online gambling operator. Four: misusing someone's personal records is a crime punishable by prison, and companies themselves can be prosecuted. Five: telecoms operators can be ordered to hand over the encryption method they use.High confidence
What's about to change?: The biggest thing is what has not happened. Spain still has not passed the law that brings Europe's new cybersecurity rules into Spanish law, so the old 2018 regime is still what binds — expect that to change and to widen sharply who must report incidents. From 12 January 2027 no cloud provider may charge you to leave or to pull your data out. Watch three switches the government can flip with no consultation: taking over telecoms networks, ordering gambling systems into Spain, and demanding an operator's encryption method.Medium confidence
Hardest industry wall: None found.

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
