Manufacturer's Warranty

Tempdrop devices come with a standard one-year manufacturer's warranty. You can upgrade this to two years with the optional satisfaction guarantee add-ons (Tempdrop Care and Care+). The warranty starts from the date of purchase.

Armbands are covered under a three-month manufacturer's warranty.

Please contact us at support@temp-drop.com to troubleshoot any issues. All assessments are done remotely for your convenience. If we determine the issue is due to a manufacturing defect, we will exchange it and cover the shipping costs.

To initiate a claim under warranty, the following process must be followed:

  • Open the Tempdrop app and click the "message" icon on the top left section of the main screen or through "contact support" in the app's menu. If you don't have access to the Tempdrop app, please email support@temp-drop.com. In your message, provide as much information as possible about the issue, along with screenshots, photos, and/or videos when appropriate.
  • A remote assessment will be carried out to determine the cause of the fault.
  • Incidents that fall outside the scope of the manufacturer's warranty include (but are not limited to) accidental user damage, loss, water damage, normal wear and tear, cosmetic damage, and incorrect battery placement.
  • Where a user attempts to resolve the issue themselves without the guidance of a Tempdrop employee, the warranty will be void. Please do not open the Tempdrop for any reason other than to change the battery when prompted (following the guidance in the app menu) or at the direction of a Tempdrop team member.

Tempdrop Insurance

Protect your Tempdrop sensor against accidental loss or damage. Add it after purchase at any time.

Insurance T&Cs:

One-year renewable insurance against loss or accidental damage of your Tempdrop sensor.

  • First claim replacement on your Tempdrop sensor is free.
  • Additional claims within the same year are subject to an extra $49 fee for each replacement sensor.
  • $19 processing fee for every claim.
  • Armband replacements can be added to each sensor claim for an additional $9.
  • Insurance cannot be added retroactively after loss or damage. Sensor activity will be checked before a claim is approved.
  • The original sensor will become the property of Tempdrop and will be deactivated. If a lost sensor is found, it must be returned to Tempdrop.

To start an insurance claim, contact support through the Tempdrop app. Provide the insurance order number, user email address (app login), and details. To renew your insurance annually ($45), contact our team.
