We take our Members' privacy very seriously. Our Privacy Policy does a good job of explaining how we use your information ( Rakuten.com/help/article/privacy-policy-360002101688 ). The permissions set by our extension allow it to track your eligible purchases for Cash Back. Our Members may also use our services without adding our Cash Back Button extension. It is just one of the many ways we offer to our Members to make our services work for them. They may shop through our website (Rakuten.com) or through our mobile app (available on Android phones, iPhones, and iPads) as well. If you have any more questions, don’t hesitate to reach out to us at memberservices@rakuten.com. We are here to help!
