Hints or notes are confusing

Sound or vibration feedback
Haptic feedback can be managed from Settings inside the app. Device-level vibration settings may also affect how feedback feels.
Ads or privacy choices
If privacy options are required in your region, they are available from Settings. You can also contact support for privacy-related questions.
