# Why does the HealthKit permission sheet only show once?

Apple shows the HealthKit permission sheet **only once per app, per device install**. After that first prompt, iOS will not re-show it, even if scopes were denied. This is an Apple platform constraint, and there is no API workaround.

The only way for a user to change their grants is:

* **Settings > Privacy > Health > \[your app]**
