Refund policy

Last updated: 29 September 2026

Try it for 30 days, not satisfied = money back

Try your sleeves for 30 days. Wear them during sport and in daily life. If you are not satisfied, you get your money back. Even if you have worn and washed them.

How it works:

Within 30 days of receiving your order, email support@humandynamix.run with your order number and the products you are returning. You will receive the return address and instructions.
Send the products back within 14 days of your email, complete and washed according to the care label.
Once we receive your return, we refund you within 14 days via your original payment method.

Good to know:

Return shipping costs are yours, unless the product is defective or we sent you the wrong item. Use a tracked shipping method.
The trial period applies once per customer per product.
If you ordered with a bundle discount and return part of it, you get back the part of the amount paid that belongs to those products.
If you return your entire order, we also refund the shipping insurance.
If you received a program for free with your order, you may keep it.

Your statutory right of withdrawal

Separately from our trial period, as a consumer you have the statutory right to withdraw from your purchase within 14 days without giving a reason:

Physical products: within 14 days of receipt. Our 30-day trial period is longer, so you are always covered by it.
Digital programs: within 14 days of purchase, even if you have already downloaded the files. After the refund, your right to use the program ends and you delete the files.
Coaching: within 14 days of purchase. If you asked us to start within those 14 days, you pay a proportionate amount for what has already been provided. See our Terms of Service, section 9.

To withdraw, email support@humandynamix.run, optionally using the model form below. We refund you within 14 days of your notice. For physical products, we may wait until we have received the products back or you have sent proof of shipment.

1-year warranty

Our sleeves come with a 1-year warranty against manufacturing defects under normal use, such as seams coming loose or a band losing its grip. If you have such a defect, email us your order number and a few photos. We send you a new one, or refund you if replacement is not possible. We cover the costs.

The warranty does not cover normal wear and tear, damage from incorrect washing or drying (follow the care label), damage from misuse or accidents, or a size that does not fit (that is what the trial period is for).

This warranty is in addition to your statutory rights and does not limit them. If a product has a defect that was present at delivery, the law always entitles you to free repair or replacement, and in some cases to a price reduction or a refund. Also after our warranty has ended.

Received a damaged or wrong product?

Let us know as soon as possible at support@humandynamix.run, with your order number and a few photos. We send a replacement or refund you. We cover the costs.
