"Apart from publicly available privacy policies, how does Niantic inform parents about how their child's information is collected and used?," Franken asked in his letter.
Niantic could not be immediately reached for comment on Franken's letter. A spinout from Google in August, Niantic has the Pokémon Company, Google and Nintendo as investors.
The service also collects a device identifier, user settings, and the operating system of the users' device, as well as information about the use of its services from the mobile device, which it may use to improve and personalize services.
Niantic also collects log data, which it says "may include information such as a User's Internet Protocol (IP) address, user agent, browser type, operating system, the web page that a User was visiting before accessing our Services, the pages or features of our Services to which a User browsed and the time spent on those pages or features, search terms, the links on our Services that a User clicked on, and other statistics."
