Apple is not collecting your answers from the screening tool. To help improve the site, Apple collects some information about how you use it. The information collected will not personally identify you.
Reported by Bloomberg, even so, four US senators have asked Tim Cook for more details:
Senators Bob Menendez, Kamala Harris, Cory Booker and Richard Blumenthal sent a letter to the company on Friday expressing concern “for the safety and security of Americans’ private health data.” They want to know about data-sharing practices and safeguards, and whether the app complies with the Health Insurance Portability and Accountability Act (HIPAA). The senators are also seeking information on Apple’s agreements with federal or state governments for the development of the app, according to the letter, a copy of which was obtained by Bloomberg.
