Privacy policy.

For questions about information you have shared, contact the Mắt Rồng Digital team through Zalo or the phone number listed on the Contact page.

When you submit a form, the website sends your contact details and completed fields to the server for validation and delivery to our team’s Telegram chat. Share only what is needed for your enquiry; do not include passwords or system access credentials.

The website does not save form content in cookies, localStorage, sessionStorage or a separate database. The next section explains how the estimate summary is carried in the page address. The server temporarily keeps technical identifiers and delivery statuses to limit duplicate submissions and form abuse. Delivered messages are kept in Telegram for our team to review and respond.

You may share contact details, a website or Google Maps profile address, your requirements, existing systems, budget or timing. This information is used to understand the request, reply and agree the scope of work.

Calculator choices are stored in the page address, and the estimate summary can be carried to the enquiry form. If you edit that summary and switch language, the updated text is carried to the next page. Content in the page address may remain in your browser history.

The store, chatbot and CRM demos use prepared sample data. Demo actions run only within the open page and do not send enquiries or create real orders; reloading the page resets their state.

When you click Zalo or a phone link, the website sends a notification to our team’s Telegram chat with the channel, the page path without URL query parameters, the page language and the link’s position. This notification does not send your IP address or form contents to Telegram. A click does not confirm that a call or conversation took place.

The server temporarily retains hashed technical identifiers and delivery status to limit duplicate notifications and abuse. Contact-click tracking does not use cookies or browser storage.

Telegram, Zalo and linked websites operate under their own policies. When you open or send information through those services, their handling of data depends on the service you choose.

The website does not install general traffic analytics or advertising scripts. The hosting provider may process technical data needed to deliver and protect its service, such as IP addresses and request logs.

You can get in touch to ask about information you sent, request a correction or ask for its deletion. Identify the relevant conversation so the information can be located. Handling data on an external platform also depends on that platform’s tools and policies.
