Terms of Service

Applies to the Sale Agent service at netorder.lanhiatelier.com.
Effective date: 7 September 2026 · Last updated: 7 September 2026

These terms are an agreement between Sale Agent ("we", "us") and the business that opens an account ("you", "the shop"). By creating an account or using the service you accept them. If you are accepting on behalf of a business, you confirm that you are authorised to do so.

1. What the service is

Sale Agent is a hosted software service that connects to messaging channels a shop already owns — a Facebook Page, a Zalo Official Account, a Zalo personal account — receives customer messages, replies to them using the shop's own product catalogue and knowledge base, and assembles pending orders for the shop's staff to approve.

Sale Agent is an independent product. It is not affiliated with, endorsed by or sponsored by Meta Platforms, Inc. or VNG Corporation.

2. Accounts and access

• You must give accurate registration details and keep your password secret. You are responsible for everything done under your account.
• An account belongs to a company (a "workspace"). The owner may invite staff and set each person's role.
• Tell us promptly if you believe an account has been used without permission.

3. Connecting a channel — your responsibilities

• You may only connect a Facebook Page, Zalo Official Account or Zalo account that you own or are authorised to administer.
• When you connect a channel you instruct us to receive and send messages on your behalf on that channel.
• You remain responsible for complying with the rules of that platform — including Meta's Platform Terms, Developer Policies and Messenger Platform policy, and Zalo's equivalent rules — and with the law that applies to your business, including consumer-protection and personal-data law.
• You must tell your customers, in a way that suits your business, that their messages are handled with the help of an automated assistant.
• Connecting a Zalo personal account carries a risk that the account is restricted by the platform. The connection screen warns about this. You accept that risk.

4. What you must not do

• Send unsolicited bulk messages, spam or content that platform rules forbid.
• Use the service for anything illegal, deceptive, or harmful, or to sell goods you may not lawfully sell.
• Upload content you have no right to use, or content that is unlawful or infringes someone's rights.
• Attempt to access another shop's data, probe or interfere with the service, or resell access to it without a written agreement with us.
• Use the service to build a competing model or dataset from other shops' data.

5. The assistant, and the limits of automation

By design, the assistant cannot move an order to confirmed, shipping or done — only a member of your staff can. Do not build a process that relies on the assistant making that decision.

6. Your content and your data

Your catalogue, knowledge base, conversations, customers and orders remain yours. You grant us only the licence needed to host and process that material in order to run the service for you, as described in the Privacy Policy.

You confirm that you have the right to give us the customer data that reaches the service through your channels, and that you will handle requests from those customers as the law requires.

7. Plans, limits and payment

• Each plan includes a monthly allowance of AI-handled conversations. Usage is measured and shown in the application.
• When an allowance is used up, AI replies for that workspace stop until the next period or until the plan is upgraded. Your inbox, your data and manual replies keep working.
• Fees, if any apply to your plan, are stated when you subscribe. Unless the law says otherwise, fees already paid are not refundable for a period already begun.

8. Availability, changes and third parties

We aim to keep the service available and will give notice of planned maintenance where we reasonably can. We may add, change or withdraw features; if a change materially reduces what you rely on, we will tell you in advance.

The service depends on platforms we do not control. If Meta or Zalo changes an interface, restricts a permission, or suspends an account, parts of the service may stop working. That is outside our control and is not a breach of these terms.

9. Suspension and termination

• You may stop using the service and close your account at any time.
• We may suspend or close an account that breaches these terms, that puts the service or other users at risk, or where we are required to by a platform or by law. Except in an emergency, we will warn you first and give you a chance to fix the problem.
• After closure, your data is deleted as described in the Privacy Policy and on the Data deletion page. Export what you need before you close the account.

10. Warranties and liability

The service is provided "as is". To the extent the law allows, we do not warrant that it will be uninterrupted, error-free, or that automated replies will be accurate for every case.

To the extent the law allows, we are not liable for indirect or consequential loss, for lost profit, or for loss of data that you could have avoided by exporting it. Our total liability for any claim is limited to the fees you paid us for the service in the three months before the claim arose.

Nothing here excludes liability that cannot lawfully be excluded.

11. Changes to these terms

We may update these terms. The date at the top of this page always shows the current version, and we will notify you in the application before a material change takes effect. Continuing to use the service after that means you accept the new version.

12. Governing law

These terms are governed by the law of the Socialist Republic of Vietnam. Disputes we cannot settle by discussion will be resolved by the competent courts of Ho Chi Minh City.
