LegalPrivacy Policy

This website is run by me, Wilhelm Dang, founder of DANGPERFORMANCE, based in Ho Chi Minh City, Vietnam. I'm responsible for the personal data described in this policy. For any privacy question, email wilhelm.dang@gmail.com.

There are no forms on this website, so it never asks for your name, email address or phone number.

• No cookies, and nothing is stored on your device.
• No analytics, advertising pixels or social-media tracking.
• Fonts and images are served from this website itself, so viewing a page doesn't connect your browser to other companies' servers.

The website is hosted by Vercel Inc. Like any website, it receives the technical information your browser sends automatically: your IP address, browser type, the page requested and the time of the request. Vercel processes this to deliver the pages and protect the site against abuse, and may keep it in server logs for a limited period. It may be processed on servers outside Vietnam, including in the United States. I don't use it to identify you or to build a profile of you. See Vercel's privacy notice for details.

The contact buttons open Zalo, WhatsApp or your own email app. The WhatsApp button pre-fills a short greeting, which you can edit or delete before sending. The website itself doesn't send or store anything.

When you message me, the service you choose — Zalo (VNG), WhatsApp (Meta) or email (my inbox is Gmail, run by Google) — processes your message under its own privacy policy. I receive what you send: usually your name, your phone number or email address, any profile details the app shows, and your message.

Only to reply to you, answer your questions and arrange your free consultation. I don't add you to a mailing list or send you marketing, and I never sell or share your details.

If you become a client, I'll explain separately how the information needed for your coaching is handled.

I keep your messages only as long as I need them to reply and follow up on your enquiry. You can ask me to delete them at any time. Copies may remain in your own app and with the messaging or email provider, under their policies.

You can ask what personal data I hold about you, and ask me to correct or delete it, by emailing wilhelm.dang@gmail.com. Depending on where you live, data-protection laws such as Vietnam's personal data protection law or the EU General Data Protection Regulation (GDPR) may give you further rights, including the right to complain to your local data-protection authority.

This website links to Instagram, WhatsApp and Zalo. Once you follow a link, that service's own privacy policy applies.

If the website changes — for example, if I add a contact form or analytics — I'll update this page first and change the date at the top.
