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

Hong Kong SARChecked 18 August 2026

In one paragraph
Hong Kong's privacy law contains a cross-border transfer ban that has never been switched on. It was written in 1995 and, thirty years later, still has no start date. So under the general law you can send personal data anywhere with no paperwork at all. The privacy regulator is busy and prosecutes people, but it cannot fine you directly.
The catch
The free-for-all stops at three doors. Licensed securities and futures firms need written permission from the markets regulator before their records live only on servers outside Hong Kong. Government departments are told not to put sensitive or personal information on public cloud at all. And data coming the other way, from mainland China into Hong Kong, is tightly controlled by mainland law, not by Hong Kong law - that is the wall most companies actually hit.
Does this apply to me?
Yes, it can reach you with no office in Hong Kong. The privacy law bites on whoever controls the collection, holding, use or processing of personal data in or from Hong Kong, so a foreign company running a Hong Kong-facing service is caught. There is no revenue or headcount threshold to fall below, no register to join, and no requirement to appoint a local representative. The anti-doxxing powers go further still: the regulator can order an overseas platform to take material down.High confidence
Can the data leave the country?
Under the general privacy law, yes - freely, with nothing to sign. The one section that would have restricted transfers abroad was written into the law in 1995 and has never been brought into operation, so today there is no legal control on personal data leaving Hong Kong. Industry rules are where the real limits sit, and there are fewer of them than people expect: the securities regulator is the main one, and government departments have their own restriction.High confidence
What do I have to do to send it abroad?
Nothing. There is no approval to seek, no standard contract to sign and no government list to check before personal data leaves Hong Kong. The model on paper is an allowlist - the regulator would publish a list of approved destinations - but because the section was never switched on, that list has never been issued and is empty. The regulator does publish a voluntary guide and encourages firms to build the safeguards now, but that is advice, not law.High confidence
Who enforces this — and are they actually working?
The Privacy Commissioner for Personal Data, and it is genuinely busy. By the end of December 2025 it had issued 2,104 orders to 57 online platforms to take down 33,743 doxxing messages, opened 519 criminal investigations and arrested 81 people. But there is a catch that changes the risk picture completely: the Commissioner cannot impose a fine for breaking the privacy principles. It serves a notice telling you to fix the problem, and only ignoring that notice is a crime.High confidence
How long must I keep it, and when must I delete it?
There is a hard ceiling and almost no floor in the privacy law itself. You must erase personal data once it is no longer needed for the purpose you collected it for, and failing to do so is a criminal offence carrying a fine of up to HK$10,000 (about $1,300). The privacy law sets no minimum keeping periods; those come from tax, company and anti-money-laundering law instead. Where the two pull against each other, the specific keeping duty in the other law wins, and you delete once it expires.Medium confidence
What happens when something goes wrong?
For a normal data breach there is no deadline, because there is no duty. Telling the Privacy Commissioner about a breach is voluntary in Hong Kong - the regulator asks you to do it as good practice and gives you a form, but no law compels it. That is unusual and it is changing: since 1 January 2026 operators of designated critical infrastructure must report computer-system security incidents, so those firms now have a real clock while everyone else has none.High confidence
What's the trap?
Five things that catch people out. First, marketing mistakes are crimes here, not fines - using someone's data for direct marketing without the right consent can mean five years in prison. Second, the regulator cannot fine you, so people assume the risk is low and miss the criminal exposure entirely. Third, Hong Kong sets no age at which a child can consent, so there is no simple number to code into a sign-up flow. Fourth, licensed securities firms need written permission before their records live only on overseas servers, and two named people who live in Hong Kong must be able to unlock them. Fifth, the dormant transfer section, if ever switched on, would also catch data moving between two foreign countries when a Hong Kong company controls it.Medium confidence
What's about to change?
Nothing is scheduled to land in the next twelve months that we could confirm. The critical infrastructure security law already started on 1 January 2026, and the government's guideline for generative artificial intelligence was revised in December 2025. The thing to watch is not a new bill. It is a switch the government has held for thirty years: the cross-border transfer section can be brought into force by a simple commencement notice, with no consultation and no new vote.Medium confidence
