Amazon has launched Amazon Shopper Panel, a program that will pay users for information on their non-Amazon purchases.

In addition to sales, one of the biggest benefits Amazon gains is access to customer and purchasing data. For purchases made outside Amazon, however, the company is largely in the dark.

To address that, Amazon has unveiled Amazon Shopper Panel. The program “is an opt-in, invitation-only program where participants can earn monthly rewards by sharing receipts from purchases made outside of Amazon.com and by completing short surveys.”

The company emphases its commitment to privacy, promising that Amazon only receives information that panelist explicitly share, and that panelists can stop at any time. In addition, panelist have the option to delete any previous receipts, and Amazon automatically deletes sensitive information, such as prescription receipts.

At this time the program is only available to a limited number of users, but those interested can join a waitlist to be informed when it becomes more widely available.
