EstoniaChecked 18 August 2026
Depends on your industryWork: MediumEnforcement: Active
In one paragraph
Estonia has no general rule forcing data to stay in the country, and it adds very little on top of the European privacy rules. Two industries are the exception. Phone and internet companies must keep connection records inside the European Union, with some records physically in Estonia. Online gambling firms may only run their game server from a short list of approved countries. The regulator works, but its fines are small.
The catch
The relaxed headline stops being true the moment you are a telecoms operator, an online gambling operator, a health care provider or a public body. Telecoms connection records may not leave the European Union at all and certain police-request records must sit on Estonian soil. Gambling servers are limited to an approved list of countries. Health records carry a 30-year minimum keep-time. Public bodies must run the Estonian national security standard and exchange data through the state's own data layer.
Does this apply to me?
Yes, it reaches you even with no office in Estonia. Estonia does not write its own reach test — it uses the European Union's. If you offer goods or services to people in Estonia, or track what they do online, the European privacy rules apply and Estonia's regulator can act against you. There is no size or revenue threshold to fall below. A company with no branch anywhere in Europe normally has to name a written representative inside Europe.High confidence
Can the data leave the country?
In general, yes. Estonia has no law telling companies to keep personal data in Estonia, and European law actually forbids member states from imposing one on non-personal data. Two industries break that headline. Phone and internet companies must keep their call and connection records inside the European Union, and certain police-request records must stay physically in Estonia. Online gambling companies may only place their game server in Estonia, in a country that has signed the cybercrime treaty, or in a country whose regulator has a cooperation deal with the Estonian Tax and Customs Board.High confidence
What do I have to do to send it abroad?
For the normal routes you file nothing with the Estonian regulator. If the destination country has been officially approved by the European Commission, you simply send the data. If it has not, you sign the European Commission's standard contract with the recipient and run a risk check on the destination first. Only two routes need Estonia's regulator to sign off: group-wide internal rules where the parent company is in Estonia, and a one-off contract you wrote yourself.High confidence
Who enforces this — and are they actually working?
The Data Protection Inspectorate, and it is genuinely working. It has 34 posts, a director general in her second term since May 2024, and it publishes its orders. In 2025 it took in 1,568 complaints, issued 13 orders and imposed 5 penalties. But note the shape of the risk: Estonian data protection penalties are handled like minor criminal charges, so they are slow and small, and no Estonian fine has ever approached the European ceilings. Cyber rules are enforced separately by the Information System Authority, which also publishes orders — the most recent on 5 June 2026.High confidence
How long must I keep it, and when must I delete it?
Estonia has some of the longest minimum keep-times in Europe. Health records must be kept for 30 years. Anti-money-laundering paperwork for 5 years after the customer leaves. Phone and internet connection records for 1 year, and the police request logs behind them for 5 years. Gambling records for 5 years. Going the other way, a dead person's data stays protected for 10 years after death, or 20 years if they died as a child, and a missed payment may only be reported to credit agencies between 30 days and 5 years after it happened.High confidence
What happens when something goes wrong?
Count three clocks, not one. If personal data leaks, you have 72 hours to tell the Data Protection Inspectorate, and you must tell the affected people without delay if the risk to them is high. If you run an important or essential service, you have only 24 HOURS to send a first cyber-incident warning to the Information System Authority, then 72 hours for a fuller report, then one month for a final report. Trust service providers such as e-signature and certificate companies must send the fuller report inside 24 hours too. Missing the cyber deadline is punished separately from missing the privacy one.High confidence
What's the trap?
Six things that are not in the summary. (1) A child in Estonia is anyone under 13 for online services, not 16 as in much of Europe, so a consent flow tuned to Germany will over-block Estonian teenagers. (2) A dead person's data stays protected for 10 years after death, 20 if they died as a child, and the heirs control it. (3) Research on Estonians must be stripped of names BEFORE the data are handed over, an ethics committee must sign off sensitive projects, and you must name the individual who holds the key. (4) Data protection fines are handled like minor criminal charges, which makes them small but also drags a named human being into the process. (5) Since 1 January 2025 the regulator itself can sue you in court on behalf of a whole group of affected people. (6) Under the cyber law a named board member is personally responsible for security and must attend training.High confidence
What's about to change?
One near-term date stands out. Estonia's official gazette marks its own current texts of the privacy, public information, cybersecurity, telecoms, emergency, health services, health insurance and social welfare acts as valid only until 30 September 2026, so a further change starts on 1 October 2026. We could not identify the amending law, so treat that date as a hard diary entry. Beyond it, the cyber rules phase in: registration was due by 1 April 2026 and full compliance is due by 1 January 2029. From 12 January 2027 European rules make cloud switching and data export charges free.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
