2. Definitions

• Personal data: digital data or information in any other form that identifies or helps to identify a specific individual. Information about companies, projects and industrial parks is not personal data, except for any part linked to a specific individual.
• Sensitive personal data: data in the categories listed in Decree No. 356/2025/NĐ-CP, for example health, biometric and location data, card information and bank transaction history, and data tracking a person's behaviour when using online services.
• Data subject, "you": the individual to whom the personal data relates.
• Processing of personal data: any operation performed on data, such as collection, analysis, storage, provision, public disclosure, transfer and deletion.
• Processor: an organisation that processes data on behalf of HOUSELINK under a contract, for example server and email service providers.
• Member: an organisation or individual with an account on the HOUSELINK platform, whether free or paid.

3. Personal data we process

We collect only the data needed for the purposes set out in section 4.

4. Purposes and legal bases for processing

Each purpose has its own legal basis. Where the basis is consent, you give consent separately for each purpose, with no pre-ticked boxes, and may withdraw it at any time. Silence or failure to respond is not treated as consent.

Where we need to use data for a new purpose, we will notify you in advance and obtain your consent where the law requires it.

5. Company information and contact persons on the platform

The HOUSELINK platform provides information about companies, projects and industrial parks. We do not sell, rent or transfer personal contact information, whether under a service package or on request.

• Company information (name, enterprise code, address, business lines, general email, switchboard number) is not personal data.
• Legal representatives: only the full name and job title are displayed, exactly as published on the National Business Registration Portal, together with the source and date of update. The legal representative's phone number, personal email, identity document number and address are not displayed.
• Other contact persons: their full name and job title are displayed only if they consent. Without consent, the platform displays only a department or a generic role, for example "Purchasing department".
• Individuals' phone numbers and email addresses are not displayed to members. Members who wish to make contact send a connection request through HOUSELINK; we forward the request to the company's general email address or to a person who has agreed to receive connection requests.

If you find your information on the platform, you can email info@houselink.com.vn with a link to the page containing that information.

6. Cookies, analytics and marketing emails

All non-essential cookies are off until you turn them on. You make your choices in the cookie settings panel when you first visit the website and can change them at any time using the button below or the "Cookie settings" link in the footer. The "Reject all" button is as easy to see as the "Accept" button.

Open cookie settings

We do not track your activity on other websites and do not use behavioural advertising. View and follower counts for company profiles are shown only as numbers; companies are not told who has viewed or followed them.

Marketing emails and service notices

• Newsletters and marketing information are sent only to people who have subscribed. When you subscribe, you are informed of the content, format and frequency of the mailings.
• Every marketing email contains an unsubscribe link. When you unsubscribe, the system stops sending immediately and does not resume.
• We do not measure email opens or link clicks person by person; we only look at aggregate figures for each campaign as a whole.
• We do not send marketing emails to purchased lists or to contacts who have not consented.
• Service notices to members (renewals, changes to terms, security alerts) are sent separately and contain no advertising.

7. HOUSELINK AI and automated processing

HOUSELINK AI answers questions about projects, companies and industrial parks within the permissions of your account.

• The question box states clearly that you are asking an artificial intelligence assistant.
• The context sent to the model contains no personal contact information. HOUSELINK AI does not answer questions aimed at looking up or compiling information about an individual.
• Please do not enter your own or other people's personal information in your questions.
• Questions are separated from your account before being stored and are deleted after 90 days.
• Data sent to the model is not used by the provider to train models, under the terms of the service plan that HOUSELINK uses.
• Insights reports prepared with the assistance of artificial intelligence are labelled as such and are reviewed and approved by a person before publication.

We do not use automated processing to make decisions that have legal effects on individuals. Rankings and ratings on the platform apply to companies, not to individuals. You have the right to request that your data not be subject to automated processing, and to ask a member of HOUSELINK's staff to review a result generated by the system.

8. Who we share data with

We do not sell personal data. Data is provided only to the parties listed below, to the extent necessary.

If HOUSELINK undergoes a corporate reorganisation (merger, division, separation or transfer), data will be transferred only in accordance with the law and we will notify you.

9. Storage in Vietnam and transfers of data abroad

The HOUSELINK platform's application servers, databases and backups are located in Vietnam.

Some Google services that we use may process data in data centres outside Vietnam:

• Email addresses, the content of correspondence with HOUSELINK and the emails we send to you;
• Google account information when you choose to sign in with Google;
• Google Analytics measurement data, when you enable analytics cookies.

We keep the data sent abroad to a minimum.

10. Retention periods

Data is kept only for as long as needed for the purposes of processing or for the period required by law. When that period ends, the data is deleted or de-identified.

11. Your rights and how to exercise them

Under Article 4 of the Law on Personal Data Protection, you have the right:

How to submit a request

• Email info@houselink.com.vn, clearly stating your request and the information concerned;
• Call the hotline on (+84) 966 222 490 or the switchboard on 024 3795 5620 during working hours;
• Write to or visit HOUSELINK's head office in person; members can submit requests on the "My privacy" page in their account.

Exercising your rights is free of charge. To avoid disclosing your data to the wrong person, we verify your identity through your logged-in account or your registered email address. We ask for additional information only where this is not sufficient, and we do not request a photo of your citizen identity card unless it is necessary.

Time limits under Article 5 of Decree No. 356/2025/NĐ-CP:

If we extend a time limit, we will inform you of the reason before it expires. Unsubscribing from the newsletter and turning off cookies take effect immediately, without waiting for the time limits above.

Where we cannot fully comply, for example where the law requires us to continue retaining accounting records, or where providing the data would affect the rights of others, we will reply in writing, stating the reasons and the legal basis.

Complaints: you can submit a complaint to HOUSELINK's Personal Data Protection Officer. You also have the right to lodge a complaint or report a violation with the specialised personal data protection authority under the Ministry of Public Security, or to bring a lawsuit in court.

12. Data protection and incident handling

We apply organisational and technical measures appropriate to the level of risk to the data:

• Encryption of connections between your browser and our servers (HTTPS/TLS); protected backups;
• Role-based access control, under which access is granted only where needed for work; mandatory two-factor authentication for administrative staff;
• Detailed personal contact information can be viewed only by a small number of administrators, and every view is logged;
• Staff sign confidentiality undertakings and receive regular training;
• Providers that process data must sign contracts containing confidentiality obligations;
• New features that use personal data are assessed before launch.

In the event of a leak or loss of, or unauthorised access to, personal data, we take immediate action to contain it. We notify the specialised personal data protection authority within 72 hours and notify affected individuals in accordance with the law. Incident records are retained for inspection purposes.

13. Children's personal data

HOUSELINK's services are intended for organisations, companies and adults working in industrial real estate and investment. HOUSELINK does not knowingly collect personal data of persons under 18, including children (persons under 16), and does not design its services for children.

• When registering an account, you confirm that you are 18 or older.
• If we discover that we have collected a child's data without consent as required by Article 24 of Law 91/2025/QH15, HOUSELINK will stop processing and delete that data without delay.
• Parents or guardians may contact us as set out in section 16 to request a review and deletion.

14. Possible risks and unintended consequences

Although we apply the measures described in section 12, no system is completely secure. Possible risks include:

• unauthorised access resulting from cyberattacks or software vulnerabilities;
• human error, for example sending an email to the wrong recipient or granting the wrong permissions;
• account takeover because a password has been exposed or is reused on other services;
• emails, messages or calls impersonating HOUSELINK for fraudulent purposes.

Consequences may include receiving spam, being defrauded or being impersonated. To reduce these risks, you should use a unique password for HOUSELINK, not share your account and sign out of shared devices.

15. Changes to this policy and languages

• This policy is reviewed periodically and whenever the law or HOUSELINK's data processing activities change.
• For material changes (new purposes, new categories of data, new recipients, new transfers of data abroad), HOUSELINK gives notice on the website and by email to account holders at least 7 days before the changes take effect. If a change requires consent, HOUSELINK will ask for your consent again; continued use of the services is not treated as consent.
• This policy is published in Vietnamese, English, Japanese, Korean and Chinese (Simplified) with the same version number and effective date. In case of any discrepancy between versions, the Vietnamese version prevails.

16. Contact

For any questions or requests concerning personal data, please contact the Personal Data Protection Officer, HOUSELINK Joint Stock Company. We will acknowledge receipt of your request and reply within the time limits set out in section 11.
