Privacy Policy

MSONE (“we”, “us”) respects and is committed to protecting your personal data. This policy explains how we collect, use, store and protect personal data when you use our website, in accordance with the Law on Personal Data Protection No. 91/2025/QH15 and Decree No. 356/2025/NĐ-CP.

1. Data controller

MS-ONE COMPANY LIMITED — Tax code: 2401070985. Address: No. 3, Alley 9, Lane 842, Lê Lợi Street, Bắc Giang Ward, Bắc Ninh Province, Vietnam. For any questions about personal data, please contact hotro.msone@gmail.com — 0966 968 616.

2. Data we collect

We only collect text data that you actively provide through forms on the website, including:

• Full name, email, phone number;
• Company name and the content of your request/message;
• Basic technical data (device type, browser) and anonymous traffic measurement data (if you accept cookies).

We do NOT request and do NOT store photos of citizen ID cards, passports or sensitive identity documents via the website. When such documents are needed to deliver a service, we exchange them through a separate secure channel as agreed.

3. Purposes and legal basis

We use data to: contact you for consultation, quotes and service delivery; respond to your requests; and improve the website and its content. The legal basis is your consent (when you submit a form/subscribe) and the performance of the service contract between the parties. When you subscribe to our email newsletter, we confirm your email (double opt-in) and you may unsubscribe at any time via the “Unsubscribe” link at the bottom of every email.

4. Cookies and measurement

The website may use cookies to remember your preferences and measure anonymous traffic. With your consent, we use Google Analytics (visit statistics, with IP anonymised) and Microsoft Clarity (heatmaps and anonymised behaviour analytics, with your input content masked) to improve the experience. If you decline in the cookie notice, these tools are NOT loaded. You may change your choice in your browser settings at any time.

5. Sharing with third parties

We do not sell personal data. We only use trusted infrastructure providers to operate the website (for example: database storage, hosting, translation, email delivery and internal notifications to handle your request). These parties process data under contract and only to the extent of serving our service.

Virtual assistant (AI): when you chat with the virtual assistant on our website, the content of your messages is sent to AI services located abroad to generate a response — including Anthropic (the Claude model — to generate answers) and Deepinfra (the BGE-M3 model — to understand your question and find relevant content). We do NOT store conversation history. The assistant is intended for product questions only; please do not enter sensitive personal data into the chat. To leave your contact details, use the “Leave your info” button — that information is stored securely and is NOT sent to the AI services.

6. Storage and cross-border transfer

Some infrastructure providers may locate servers outside Vietnam. We apply appropriate measures to protect data during transfer and storage, and comply with Vietnamese law on cross-border data transfers.

7. Your rights regarding personal data

Under applicable law, you have the right to:

• Be informed of and access your personal data;
• Request correction and updating of data;
• Request deletion of data;
• Withdraw consent previously given;
• Object to or restrict data processing;
• Lodge a complaint with the competent authority.

To exercise these rights, please contact hotro.msone@gmail.com. We will respond within the statutory time limit.

8. Security and breach handling

We apply reasonable technical and organizational measures to protect data. In the event of a personal data breach, we will notify the competent authority and affected individuals as required (within 72 hours of detection, where notification is required).

9. Retention period

We retain data for as long as necessary for the stated purposes or as required by law, after which it is deleted or anonymized.

10. Changes to this policy

This policy may be updated from time to time. The updated version will be posted on this page with its update date.
