Privacy

Runtime vs SDK
Local builds may still use the macOS 26 SDK in Xcode 26. The goal is a clean run on macOS 27, not a 27-only app.
What stays the same
on-device privacy should keep the same user-facing behavior. Shipping utilities stay on-device; the marketing site does not run analytics cookies.
