The company updated its privacy policy on Sunday after users reported concerns, and on Monday, Eric S. Yuan, chief executive and founder of Zoom, posted a link on Twitter to a company blog item about the policy.

In a statement for this article, the company said it took “its users’ privacy, security and trust extremely seriously,” and had been “working around the clock to ensure that hospitals, universities, schools and other businesses across the world can stay connected and operational.”

“We appreciate the New York attorney general’s engagement on these issues and are happy to provide her with the requested information,” the statement added.

Last week, after an article on the news site Motherboard reported that software inside the Zoom iPhone app was sending user data to Facebook, the company said it was removing the tracking software.

As many school districts adopted Zoom to allow teachers to host live lessons with students, some children’s privacy experts and parents said they were particularly concerned about how children’s personal details might be used. Some districts have prohibited educators from using Zoom as a distance-learning platform.

“There is so much we simply don’t know about Zoom’s privacy practices,” said Josh Golin, executive director of the Campaign for a Commercial-Free Childhood, a nonprofit group in Boston.

In the letter, Ms. James’s office cited reports that Zoom had shared data with Facebook, and asked for further information on “the categories of data that Zoom collects, as well as the purposes and entities to whom Zoom provides consumer data.”
