Hong Kong SARChecked 18 August 2026
Depends on your industryWork: MediumEnforcement: Active
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
Hardest industry wall
None found.
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
