This policy covers everything sold on this website by Hydro Structural. To ask for a refund, a change or a return, email william@hydrostructural.com with your order number.

Online video courses

Online courses are digital. Access opens on your account as soon as you pay, so online course purchases cannot be refunded once access is open. If a lesson will not play or you cannot log in, email us and we will fix it.

Live seminars

  • Cancel at least 3 months before the first day of the seminar: full refund.
  • Cancel less than 3 months before: no refund, but you can move your place to the next session of the same seminar.
  • If we cancel or reschedule a seminar, you can choose a full refund or a place in the next session.
  • Travel and hotel costs are yours to arrange and are not refunded.

Pillows, tools, beds and other products

  • Unused items in their original condition can be returned within 14 days of delivery. Email us first and we will tell you where to send them.
  • Items that have been used cannot be returned.
  • Return shipping is paid by the buyer.
  • If an item arrives damaged or is not what you ordered, email us within 7 days of delivery with photos and we will replace it or refund it at our cost.

Shipping

We ship to the United States and mainland China only.

How refunds are paid

Approved refunds go back to the card or payment method you used. Once we issue the refund, your bank usually shows it within 5 to 10 business days.

Consultations, tutoring and everything else

For private consultations, video tutoring, mentoring, or anything this page does not cover, please contact William directly at william@hydrostructural.com.
