U.S. Senator Al Franken is looking for answers regarding the recent security concerns surrounding Pokémon Go. Franken has published a letter to CEO John Hanke of game developer Niantic about the sort of data collected by the game, how that data is used, and more.

Senator Al Franken has concerns about Pokemon Go

From the letter:

While this release is undoubtedly impressive, I am concerned about the extent to which Niantic may be unnecessarily collecting, using, and sharing a wide range of users' personal information without their appropriate consent. I believe Americans have a fundamental right to privacy, and that right includes an individual's access to information, as well as the ability to make meaningful choices, about what data are being collected about them and how the data are being used. As the augmented reality market evolves,
I ask that you provide greater clarity on how Niantic is addressing issues of user privacy and security, particularly that of its younger players.

Franken goes on to ask seven questions of Niantic about the game, such as what data Pokémon Go specifically collects, what phone functions it requires, and whether the game actually needs all of the data it collects, or if that collection can become opt-in. Franken also asks about the Google account concerns that were addressed in the most recent update.
