Strongest category: Privacy
GitHub Copilot offers a tiered privacy model that provides its strongest guarantees to paying business and enterprise customers. These organizations benefit from a strict zero-retention policy, ensuring their code is not stored or used for training, and are protected by a formal commitment from Microsoft to defend them against copyright lawsuits. For individual users, privacy relies on user-managed settings, as data collection for AI training is on by default until a user actively opts out.
