iCloud+ combines everything users love about iCloud with new premium features, including a new internet privacy service, iCloud Private Relay, at no additional cost.
According to Apple, iCloud Private Relay helps prevent websites and network providers from creating a detailed profile about you. When Private Relay is turned on, the traffic leaving your device is encrypted and sent through two separate internet relays.
This prevents websites from seeing your IP address and location and network providers from collecting your browsing activity. Neither one knows both who you are and what websites you visit.
You can customize the specificity of your IP address location. By default, Private Relay maintains your general location, which allows Safari to show you localized content and results. You can choose to share a broader location.
You can turn iCloud Private Relay on or off at any time. You can turn the feature on or off completely for a device, or adjust the settings for a specific Wi-Fi network, Ethernet network, or cellular plan (SIM).
Here’s how to set up iCloud Private Relay on an iPhone, iPad, or iPod touch that’s running iOS 15 or iPadOS 15 or later:
° On your iPhone, iPad, or iPod touch, go to Settings > [your name] > iCloud.
° Tap Private Relay, then turn on Private Relay.
iCloud Private Relay automatically protects you on all networks you join, but you can turn it off for any Wi-Fi network or cellular plan (SIM).
If you disable iCloud Private Relay for a network, it’s disabled on all your devices with Private Relay turned on.To change your location settings, tap IP Address Location.
