"We may share all or substantially all categories of your personal information with: members of The McDonald's Family; vendors who help us operate our business (including information technology service providers and marketing agencies that we use as well as those who use the information to detect or prevent fraud for us, and who may use the information to provide fraud detection and prevention services to others); ... business partners if they are involved in your customer experience."
McDonald's shares substantially all categories of personal information with a broad network of affiliates, vendors, marketing agencies, and business partners, and notably allows fraud-detection vendors to reuse the data for their own services to other clients.
