CoachFrom the Coach guide
Your plan is built on your phone.
Your plan uses your Apple Health data on your phone.
On your phone
Coach reads the runs your tracking setup writes to Apple Health. Your training history is processed on your device. It is not uploaded to DVDA Games or an external AI service.
Rules and explanations
The app's rules choose the sessions, distances, paces, and limits. When available, Apple's on-device model helps phrase explanations. Standard explanations remain available without the model.
Optional device location
When you enable location, Coach requests its own When In Use permission at neighborhood-scale accuracy. This helps select a forecast area and notice travel away from your usual running area. Health permission for workout routes is separate.
When location is unavailable
Coach can infer your usual running area from workout route starts. When the area is ambiguous, it asks where you will run. Without location or route history, it cannot infer an unseen destination. A stored forecast for the same place and hour can be used when a refresh fails.
Weather uses a separate service
Forecast requests send the selected latitude and longitude and forecast time to Apple Weather. Coach does not attach your training summary. Apple also resolves area names and time zones from locations. Coach uses no other weather service.
