Privacy Policy
Last updated: 5 September 2026
This policy explains how Thanh Hai Mechanical and Trading Company Limited ("Thanh Hai", "we", "us") handles information in connection with the website dongdinh.id.vn and with the internal software tool we use to publish our own product videos to our own social media accounts.
1. Who we are
Thanh Hai Mechanical and Trading Company Limited is a manufacturer of agricultural threshing machines, located in the Industrial Area of Xuan Tien, Xuan Truong District, Nam Dinh Province, Vietnam. Tax code 0601 162 622. Contact: +84 913 561 379.
2. Information collected through this website
This website is a static informational site. It contains no registration form, no login, no newsletter subscription, no shopping cart and no comment system. We do not ask visitors for personal data and we do not store any.
As with any website, our hosting provider's web server may record standard technical request logs (IP address, date and time, requested page, browser type) for security and reliability purposes. We do not use these logs to identify individuals, we do not combine them with other data, and we do not sell or share them.
When a visitor chooses to contact us via the WhatsApp link, the conversation takes place on WhatsApp and is governed by WhatsApp's own privacy terms. We use the contact details a business partner gives us only to answer their enquiry and to carry out the resulting commercial transaction.
3. Our internal content publishing tool
We operate an internal automation tool that publishes our own product videos and images to our own official company accounts on social media platforms, including TikTok and Facebook. The purpose is scheduling: our staff prepare product content in advance and the tool posts it at the planned time.
In connection with that tool:
- The tool is used exclusively by employees of Thanh Hai. It is not offered to the public and has no external users.
- It is authorised, by the account owner, to access only the company's own social media accounts. Authorisation can be revoked by us at any time from the platform's own settings.
- It uploads content we created ourselves — videos and photographs of the machines we manufacture — together with the accompanying caption.
- It does not read, collect, store or process the personal data of any other platform user. It does not access followers, viewers, messages, comments or any audience information.
- The only data it stores is the access credential issued to us by the platform for our own account, kept in our private company workspace and used solely to publish our own content.
4. Cookies
This website does not set advertising or analytics cookies of its own. Our hosting provider may set strictly technical cookies required to deliver and protect the site.
5. Sharing
We do not sell, rent or trade personal information. Information is shared only where necessary to run our business — for example with a freight forwarder or a bank in order to execute an order a customer has placed with us — or where required by Vietnamese law.
6. Retention and security
Business correspondence and transaction records are kept for as long as required for commercial and legal purposes under Vietnamese law. Access credentials for our own social media accounts are stored in restricted internal systems accessible only to authorised staff.
7. Your rights
If you have contacted us and wish to know what information we hold about you, or to have it corrected or deleted, write to us at the address above or message us on +84 913 561 379. We will respond within a reasonable period.
8. Changes
If this policy changes, the updated version will be published on this page with a new date.
