The document summarizes concerns from the Federal Trade Commission (FTC) about shopping apps that offer price comparison, deals collection, payment processing, or other shopping functions. The FTC found that many apps did not provide sufficient pre-download information about how payment disputes would be handled or how consumer data would be collected and shared. The FTC also noted that privacy policies for these apps often used vague language without clearly explaining what data is collected and how it will be used or shared with third parties. Apps were advised to more clearly disclose data practices and security measures to consumers.
