Allow changes to privacy settings

The privacy settings on your device give you control over which apps have access to information stored on your device or the hardware features. For example, you can allow a social-networking app to request access to use the camera, which allows you to take and upload pictures.

To allow changes to privacy settings:

1. Go to Settings and tap Screen Time.
2. Tap Content & Privacy Restrictions. If asked, enter your passcode.
3. Tap Privacy, then choose the settings you want to restrict.

Here are the things you can restrict:

• Location Services: Lock the settings to allow apps and websites to use location
• Contacts: Prevent apps from accessing your Contacts
• Calendars: Prevent apps from accessing your Calendar
• Reminders: Prevent apps from accessing your Reminders
• Photos: Prevent apps from requesting access to your photos
• Bluetooth sharing: Prevent devices and apps from sharing data through Bluetooth
• Share My Location: Lock the settings for location sharing in Messages and Find My Friends
• Microphone: Prevent apps from requesting access to your microphone
• Speech Recognition: Prevent apps from accessing Speech Recognition or Dictation
• Advertising: Prevent changes to advertising settings
• Media & Apple Music: Prevent apps from accessing your photos, videos, or music library
