Microsoft is updating its GitHub Copilot data usage policy to allow for the collection of real-world user data to train its AI models, shifting the responsibility to users to manage privacy settings.
The new policy, effective April 24, allows Microsoft to collect
interaction data from Copilot Free, Pro, and Pro+ users. This data encompasses various user interactions including
code snippets, comments, documentation, and feedback, which are aimed at improving Copilot's AI capabilities. Users wishing to maintain privacy can opt out of data collection through their settings before the deadline.
However, if users do not opt out by April 24, they will be automatically included in the data collection.
According to Microsoft,
using real interactions leads to more accurate and context-aware suggestions for users. It's important to note that
Copilot Business and Enterprise users are exempt from this new data policy, highlighting a clear distinction between consumer and enterprise-use cases.
Users in private repositories have an additional layer of privacy, as their content is not used unless processed through Copilot, thus maintaining certain levels of confidentiality.
In summary, while the update aims to improve user experience through better suggestions, it places the onus on users to actively manage their data permissions.
