How an order works

• You send a build request and we arrange an intake conversation.
• We send you a build spec that describes the device, what its software will do, the price and the delivery time.
• Your order is placed when you approve the build spec and pay. Nothing is charged before that.
• We then assemble your device and write its software.

Prices and payment

Hardware is priced on request. Software builds cost from €99 to €50,000 depending on scope. Prices are in euros. The price for your order is the one in your approved build spec. We accept card payments and bank transfer. Import VAT and customs duties may apply in your country, and your build spec states whether they are included.

Made to your specification

Each device and its software are made to your personal specification. For that reason the statutory 14-day right to cancel a distance purchase does not apply once you have approved your build spec. This does not affect your rights if a device is faulty or not as described.

Warranty

Hardware is covered against defects for 24 months from delivery. If a device is faulty we repair or replace it, or refund you where neither is possible. Your statutory rights as a consumer are not affected.

Software revisions

Your purchase includes revisions to your software build for 12 months from delivery, as described in your build spec. After that period you can extend revisions for a fee.

Not medical devices

The devices we currently sell are wellness products. They are not medical devices and are not intended to diagnose, treat, cure or prevent any disease. Do not use them to make medical decisions.

Business customers

Orders from clinics, coaches, teams and resellers are governed by a separate written agreement, which takes priority over these terms.

Law and disputes

These terms are governed by the laws of the Hong Kong Special Administrative Region, and the courts of Hong Kong have jurisdiction over disputes. If you are a consumer, this does not take away any protection given to you by the mandatory consumer law of the country where you live. Please contact us first so we can try to resolve any problem directly.
