Wipe

If your device has been lost or stolen, your first priority is to protect your data and guard against identify theft. With the Wipe feature, you can achieve both by remotely deleting all files stored on the device.

Also see Submitting Lock and Wipe actions in the FAQs.

After a Wipe is sent to your device, it can't be canceled or undone, and the removed files can't be restored.
Also note that a completed Wipe fulfills the conditions of the Service Guarantee. You can't submit a Recovery request on a device that has been wiped.
