This page explains what personal information Hydro Structural collects on this website, why, and what you can ask us to do with it. Questions: william@hydrostructural.com.

What we collect

  • Your account: name, email address and password (stored only in scrambled form; we cannot read it).
  • Your orders: name, shipping and billing address, phone number, email address and what you bought.
  • Your courses: which courses are open on your account and until when.
  • Login security: the internet (IP) address of failed login attempts, kept for a short time to stop password guessing.

Payments

Payments are handled by Stripe, including card, Alipay and WeChat Pay where offered. Your card details go straight to Stripe; we never see or store your full card number. Stripe’s own privacy policy applies to the payment.

Why we use it

  • to process and ship your order and open your courses;
  • to contact you about your order, your course or a seminar you signed up for;
  • to keep the records we are required to keep for tax and accounting.

We do not sell your information and we do not send marketing emails unless you ask for them.

Who we share it with

Only the services needed to run the shop: Stripe (payments), the shipping company that delivers your order, and the company that hosts this website.

Cookies

The site uses a few cookies so that logging in and the shopping cart work, and the shop may remember which page brought you to the site when you place an order. We do not use advertising cookies.

Videos

Videos come from YouTube (English) and Bilibili (Chinese). Nothing is loaded from them until you press play; after that, those services may set their own cookies.

Where your information is kept

This website is hosted on servers outside mainland China, and payments are processed by Stripe, which operates mainly in the United States. By creating an account or placing an order you agree that your information is stored and processed there for the purposes above.

How long we keep it

Order records are kept for as long as tax and accounting rules require. Your account stays until you ask us to close it.

Your choices

You can ask to see, correct or delete your personal information, or to close your account, by emailing william@hydrostructural.com. We will reply within 30 days.

Changes

If we change this policy, we will update it on this page and change the date at the top.
