WellPD Warranty

If your WellPD wearable paired with the WellPD App stops working, or some features are not working properly, submit a request and we will help you sort it out.

If troubleshooting shows that the wearable or its accessories need to be replaced, you may be eligible for a free replacement under the following warranty terms:

US residents EU residents
  • 1 year

We cannot guarantee that WellPD will always run without interruptions or errors, but we are here to help. When you contact support, please include a detailed description of the problem and pictures if you can – this helps us assist you more effectively.


What the warranty does not cover

  • Consumable parts designed to wear down over time (i.e. battery or band), unless there’s a confirmed defect.
  • Cosmetic damage, including scratches and dents, unless caused by a confirmed factory defect.
  • Damage caused by use outside the Instructions for Use.
  • Accidental damage, such as misuse, fire, or liquid contact.
  • Damage caused by servicing or attempting to service the wearable yourself, including taking it apart.
  • Normal wear and tear from regular aging of the wearable.
  • Cases where the wearable appears to be used by someone other than the person named on the uploaded prescription* on the WellPD account.

In these cases, Empatica may decline to provide support or replace the wearable.

*Only US residents need a prescription. If you’re using WellPD outside the US, you don’t need one.
