Privacy policy

We only collect what you actively give us, plus the minimum technical data generated when you use the site.

When you submit the consultation form:

• Your name, phone number, project description, how you heard about TiumPower, and your preferred consultation date and time window (to contact you and arrange the call).
• Email, company name, and the service you are interested in (optional).
• The page you submitted from, your interface language, the ad source that brought you here (utm parameters), when you consented to data processing, and when you opted in to each type of update (if applicable).

When you chat with Tia, the AI assistant in the corner:

• Everything you type and everything Tia replies.
• Your IP address, device and browser type, the province inferred from that IP, your interface language, and the page where you opened the chat.

We never ask for, and never need, your ID number, bank details, health data or any other sensitive personal data. Please do not type any of that into the chat.

We use your information for exactly these things:

• Contacting you to advise, quote and deliver the service you asked about.
• Sending follow-up information and updates about your consultation request through the contact methods you provide if you opt in to these updates.
• Sending product, service and promotional updates only if you separately opt in to marketing updates.
• Answering your questions in the chat.
• Understanding where customers get stuck, so we can improve this site and our advice.
• Knowing which advertising channels actually work.

Both update choices are optional and independent; you can withdraw either choice by emailing support@tiumpower.com. We do not sell, trade or rent your data.

Your data lives in a database on TiumPower’s own server in Vietnam, reachable only over an internal connection and through a password-protected admin account. The whole site runs over HTTPS.

A small number of third parties process data on our behalf, each for one narrow purpose:

• Anthropic (the Claude service, United States): receives what you type in the chat in order to generate a reply. This is a transfer of data outside Vietnam.
• ipwho.is: receives your IP address to determine your province. It never receives conversation content.

Beyond those two, we disclose information only to state authorities acting on a lawful request.

Consultation form submissions are kept for at most 24 months after our most recent contact with you, unless you ask us to delete them sooner.

Conversations with Tia are kept for at most 12 months.

The copy of the conversation held in your own browser — so the chat still shows your history when you come back — expires after 7 days on its own, and disappears the moment you press “Start over” or clear your browsing data.

Tia is an AI assistant, not a member of staff. Its answers are generated by Anthropic’s Claude language model from the public content of this website.

Two things worth knowing before you type:

• What you write is sent to Anthropic’s servers in the United States to generate the reply, and is stored by us so we can see what customers are asking about.
• Tia can be wrong or incomplete. Anything it says about price, timeline or scope is indicative until a member of the TiumPower team confirms it.

For anything sensitive, or if you would rather speak to a person, message us on WhatsApp or send the consultation form.

This site uses very few cookies and sets no third-party advertising cookies.

• A "utm" cookie records the ad source that brought you here. It lasts 30 days and cannot be read by JavaScript.
• A login cookie exists only for TiumPower’s own admin account and has nothing to do with visitors.

Separately, your conversation with Tia is stored inside your own browser (localStorage) so it is still there when you return. That copy sits on your device and we cannot read it.

We currently use no web analytics tool. If that changes, we will update this page before switching anything on.

Under Vietnam’s Decree 13/2023/ND-CP on personal data protection, you may ask us what we hold about you, correct anything wrong, have it deleted, withdraw consent you previously gave, or ask us to stop processing your data.

To do any of that, email support@tiumpower.com or message us on WhatsApp at +84 705 431 776. We respond within 72 working hours, free of charge.

If you believe we are handling your data improperly, you have the right to complain to the competent state authority.

When this policy changes we update this page immediately; changes that materially affect your rights will be announced in advance.
