Sensitive image and video warnings
The Sensitive Content Warning helps adult users avoid seeing unwanted nude images and videos when receiving them in Messages, via AirDrop, in a FaceTime video message and in the Phone app when receiving a Contact Poster — all using the same privacy-preserving technology at the core of Communication Safety. The feature is optional and can be turned on by the user in Privacy & Security settings.
You (or a family member) receive a warning before receiving or sending sexually explicit photos. In Screen Time, you can also block inappropriate content and set restrictions on purchases. See Allow or block communication on a family member’s device in the iPhone User Guide.
