A year ago, this column noted the launch of Temu, a shopping app from China. Months later a Super Bowl ad spurred an estimated 50 million Americans to download it. Now Congress is proposing H.R.1153, the "Deterring America’s Technological Adversaries" (DATA) Act. The concern is that Temu and its sister app, Pinduoduo, can access a shopper's name, address, phone number, contacts, calendars, photo albums, social media accounts, chats, texts, GPS location and browsing data while bypassing and changing security settings. If you choose to delete these apps, do a full factory reset to erase all of the code.
