Privacy Policy

DeepMind Technologies Limited, is a company organised under the laws of England and Wales, with registered office at 5 New Street Square, London, EC4 3TW (“DeepMind”, “us”, “we”, or “our”).

DeepMind is a wholly owned subsidiary of Alphabet Inc. This Privacy Policy informs you of the information we collect as part of your participation in the launch of our artificial intelligence agent AlphaStar on the StarCraft II ladder on Battle.net, how we use that information and how you may manage that use.

Information we collect as part of the AlphaStar research project

We will receive and use game replays, which will include game data such as skill level, MMR, the map played, race played, time/date played, and game duration. It may be possible in certain cases to identify players from the replays and this data, and during the live games some of our team members may see the full player details that are normally shown in-game in StarCraft II. The replays we receive and the game data they contain will be the same as those usually saved by players on Battle.net, except that to protect your privacy AlphaStar will play on a StarCraft II build that will remove certain identifying details from the replays that DeepMind is able to save. The details that will be removed include usernames, user IDs and chat histories. Other identifying details will be removed to the extent that they can be without compromising the research DeepMind is pursuing.

Why does DeepMind collect this data?

DeepMind will use your replays and the related game data as part of our scientific research into, and development of, artificial intelligence. This will include publishing a scientific paper detailing the results. In particular, replays will help illustrate specific points about AlphaStar’s gameplay and will help to improve and develop AlphaStar’s performance. Replays and game data may also be used in further research and development of artificial intelligence.

Our specific uses will include communicating the results of our research (including publishing a scientific paper), publishing replays publicly, conducting further research and development, responding to queries raised by you in relation to AlphaStar’s participation on Battle.net and our use of any games you play against AlphaStar on Battle.net.

Legal basis for processing data

We will process your personal data for the purposes described in this Privacy Policy for our legitimate interests and those of third parties, including the pursuit of scientific research in the area of artificial intelligence, publishing our findings (including in a scientific paper) and the further development of our artificial intelligence agents and artificial intelligence more generally. Broadly, legitimate interests means that we can process your personal data if we have a genuine and legitimate reason and we are not harming any of your rights and interests by doing so.

Before processing data on the basis of this legitimate interest we will always carefully consider and balance any potential impact on you and your rights. We will also apply appropriate safeguards that protect your privacy, such as anonymisation or encryption techniques.

We also do not have full control of any data contained in any replays once they have been published publicly. It is also important to note that games played on Battle.net also generate data that is controlled and made public by Battle.net, which we do not have any influence over.
