This is the section that will be added to the policy:
"In the event that you choose to create an Account and play the Game, we also collect certain information regarding your in-Game performance and/or interactions with other users (e.g., wins / losses, recent champions played, average number of kills / deaths etc.). These statistics are associated with your in-Game Summoner name and are publicly accessible by members of the Riot Games community. In addition, we may share your in-Game statistics with third parties in accordance with the terms and conditions set forth in this Policy. To be clear, no personal information about you, such as your email address, username, IP address, or other sensitive information, will be shared as a part of this process."
So why the change? In short, I’m happy to confirm that for the first time, Riot Games will be providing 3rd party developers in the community a stand-alone API for accessing in-game League of Legends data. This has been one of the most popular community requests we’ve heard over the years, and we’re grateful for the patience you all have shown as we figure out the best way to accommodate this.
Why give people this data? Because people make awesome stuff with game data like stats sites, which tons of players know and love. We want to see more cool things like that come out of the community.
