Privacy policy

Your data, explained.

Applies to the current alpha version of Coach and this website. Updated 18 October 2026.

Who makes Coach.

Coach is published by Dead Villager Dead Adventurer Games (DVDA Games).

Your training history is processed on your device. Coach does not upload it to DVDA Games or an external AI service.

Health data and its purposes.

You choose which Apple Health data Coach can read. Its normal Health access is read-only.

Workouts
Coach reads your runs to make your plan and to compare each run with its session.
Workout routes
Coach uses the start point to find your home area and to see when you travel. It also reads hills and your pace changes.
Walking + running distance
Coach reads the distance of each run from this value.
Steps
Coach compares your daily steps with your usual day. A day with many more steps can be a hike or another active day.
Flights climbed
Coach compares the flights you climb each day with your usual day. Many more flights can show a hike with hills.
Heart rate
Coach uses heart rate to set your zones, to find your max heart rate and to check the effort of each run.
Resting heart rate
Coach compares your resting heart rate with your usual value. A higher value can be a sign of fatigue.
Heart rate variability
Coach uses heart rate variability as one sign of fatigue. Some watches do not record it.
Sleep
Coach uses only the times you sleep, to find your heart rate during sleep. That value shows fatigue better than resting heart rate.
Cardio Fitness
Coach shows the trend of Apple's Cardio Fitness value. Coach does not use it to set paces or zones.
Date of birth
Coach uses your date of birth to know your age. Some calculations change with age.

Coach does not sell Health data or use it for advertising. Your current recording setup must write the relevant data to Apple Health.

Location and weather.

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.

Apple handles service requests under Apple’s Weather privacy information.

Opening an external link sends a request to that website. Its privacy policy applies there.

Storage and your choices.

Coach stores plans, settings, and reflections in local app storage. Device and backup settings control any system backups.

You can withdraw read access in Apple Health. Removing Coach leaves your Health records in Apple Health.

Deleting Coach removes local app data. Retained system backups are governed by your Apple settings.

DVDA Games has no server copy of your training history to retrieve or delete.
