Bottom Line Up Front:
Apple continues to expand its Communication Safety features—designed to help protect children from inappropriate content such as explicit images in Messages—using on-device machine learning that preserves end-to-end privacy. This technology detects nudity in images and blurs them before display, giving children the option to avoid viewing the image and receive support resources.
The feature is opt-in, analyzed locally on-device, and does not share data with Apple. It’s part of Apple’s broader commitment to online child safety while maintaining strict privacy protections for all users.
What Communication Safety Does
If enabled on a child’s account, Messages will:
- Blur images detected to contain nudity before they are viewed or sent.
- Display contextual warnings and age-appropriate guidance.
- Offer help options, including:
- Leaving the conversation
- Blocking the sender
- Accessing online safety resources
- Contacting a trusted adult
Children under 13 are additionally prompted to message a parent or guardian if they encounter potentially explicit content.
What’s New in 2025
- As of iOS 17, iPadOS 17, and macOS Sonoma (14), Communication Safety is expanding to third-party messaging apps integrated via the Communication Safety API.
- Apple has extended coverage globally, including support for more regions and languages.
- New setting allows parents to manage this across all child devices from their Family Sharing account.
- Private Relay and iCloud encryption remain compatible, maintaining privacy protections while enabling safety features.
How Messages Analyzes Photos
- Uses on-device AI models trained to recognize nudity.
- Does not send content to Apple servers or store flagged images externally.
- Analysis occurs in real-time, and results are used solely for local decision-making on blurring and alerting the user.
Apple does not scan iCloud Photo Library for CSAM as part of Communication Safety. Its previously proposed iCloud scanning system was shelved in December 2022 in favor of on-device protections like this one.
How To Enable Communication Safety
You can turn this on manually for any child account in your Family Sharing group:
On iPhone, iPad, or iPod touch:
- Go to Settings > Screen Time
- Tap your child’s name under Family
- Tap Communication Safety
- Tap Continue
- Toggle Check for Sensitive Photos to On
- Enter your Screen Time passcode (if set)
On a Mac:
- Go to Apple Menu > System Settings > Screen Time
- Select your child’s account
- Navigate to Communication Safety
- Toggle Check for Sensitive Photos to On
Requires iOS 15.2 / iPadOS 15.2 / macOS 12.1 or later. For best compatibility, use iOS 17+ or macOS 14+ as newer features require updated OS versions.
What Your Child Sees
If a photo appears to contain nudity:
- The image is blurred and a warning screen is shown
- They are prompted to:
- Skip viewing the image
- Get help or contact a trusted adult
- Leave or block the conversation
Final Thought
Communication Safety is a powerful, privacy-respecting feature that gives families the tools to support their children in real-time without turning Apple into a surveillance company. When paired with Family Sharing, Screen Time limits, and digital literacy conversations, this can meaningfully reduce exposure to harmful content online.
