To limit adult websites in Safari on an iPhone or iPad, use the Screen Time content restrictions in the Settings app, this is not a search engine setting but a device-level filter. Enabling "Limit Adult Websites" automatically blocks many adult sites and lets you add specific allowed or restricted sites for child safety; you can also stop Google from asking to sign in on Safari to reduce interruptions during supervised browsing sessions.
Open the Settings app
Locate and tap the Settings icon on your iPhone or iPad home screen. This is the gray gear icon that opens the main system settings menu.
Go to Screen Time
Scroll down the Settings menu and tap Screen Time. If you haven't enabled Screen Time before, tap "Turn On Screen Time" and follow the on-screen prompts to set it up. You may need to set a Screen Time passcode to prevent changes.
Tap Content & Privacy Restrictions
Inside Screen Time, tap "Content & Privacy Restrictions." Toggle the switch at the top of this screen to enable restrictions. When the switch is green, content and privacy controls are active.
Choose Content Restrictions
Scroll down and tap "Content Restrictions" under the Allowed Store Content section. This opens a menu where you can control what types of content are accessible on the device.
Select Limit Adult Websites
Tap "Web Content," then choose "Limit Adult Websites." This option automatically blocks many adult websites while allowing all other sites. For more control, you can add specific websites under "Always Allow" or "Never Allow" below the selection. If you want to allow only a specific list of sites, choose "Allowed Websites Only" instead.
What to do if the setting keeps turning back on
If the Limit Adult Websites setting keeps reactivating automatically, it might be due to a managed account (such as a family account) or parental control applications enforcing these restrictions. A family organizer's Screen Time settings on a shared Apple ID or a managed device through Apple's Family Sharing can override your local changes. Check with the family organizer to adjust the restrictions, or if you're using a work or school device, contact your IT administrator.
If you want to use Safari on Android, note that Safari is not available on Android devices, you would need to use a different browser like Chrome or Firefox, which have their own content restriction settings.
