Privacy & data	GitHub's plans page says interactions on Free, Pro and Pro+ may be used for model training unless users opt out. Business and Enterprise add organisation-level controls.	Terminal CLI, VS Code and JetBrains can also run through supported third-party cloud providers. Check Anthropic's data usage terms for your plan.	Enterprise and Edu admins control model availability. API-key usage follows OpenAI API data terms.	Enterprise offers VPC deployment and teamspace isolation.	Enterprise adds advanced privacy controls and private networking.
