Yesterday, the internet was aflutter with a seeming overreach of Pokémon GO's access to your Google account. While that all turned out to be an error that wasn't as bad as it looked, Niantic's gone ahead and fixed things to make the whole process much more clear. Now, when you sign up for Pokémon GO with your Google account, you'll see the permissions request screen above. This is already a big step, because in the original release this screen never appeared for iPhone users, which was pretty bizarre once people figured out the app had the confusing designation of "Full Account Access". Once you approve the now basic permissions, you can go ahead and play the game without worrying about what data the app has access to. If you check your Google Account page, you can verify that Pokémon GO only has access to basic account info, which is essentially just your email address and name. If you were worried about the app's access to your Google account before, go ahead and download the update and return to your adventures.
