Google Messages Rolls Out On-Device Nudity Detection With Sensitive Content Warnings

Google has introduced a new privacy-centric feature in its Messages app, aimed at shielding users from unexpected explicit images. The feature, called Sensitive Content Warnings, automatically detects and blurs images containing nudity before the recipient opens them. After months of internal testing and an originally planned February release, the feature is now appearing for a limited group of users in the beta version of Google Messages, according to a report by 9to5Google.

This tool is designed to enhance user safety and comfort, particularly when receiving unsolicited or inappropriate content. Once enabled, the feature serves as a protective layer by scanning incoming image content for nudity and applying a blur overlay when necessary. The process is entirely on-device, powered by Android’s SafetyCore, which means that no data or image content is uploaded to Google’s servers, maintaining complete user privacy. Moreover, it does not compromise the end-to-end encryption of RCS messages.

When an image is flagged, the recipient is given three options: view the image, block the sender, or learn more about the flag. If the user chooses to view the image, the app still offers the ability to reapply the blur later. This is particularly useful in scenarios where someone else might gain temporary access to the user’s phone. Additionally, the feature warns users when they attempt to send a potentially explicit image, encouraging them to consider the implications.

For adult users, Sensitive Content Warnings must be manually turned on in the app settings. However, for teen accounts (ages 13–17), the feature behaves differently. On supervised accounts—those managed through Google Family Link—the feature is enabled by default and cannot be disabled. Unsupervised teen users can toggle the feature on or off according to their preference.

It’s worth noting that the feature currently only applies to still images and functions exclusively within supported apps like Google Messages. Video content is not yet included.

This new rollout reflects Google’s broader effort to give users more control over their digital interactions while preserving privacy and security. By leveraging on-device processing and giving users flexible options, Google aims to create a safer, more respectful messaging experience for all users, especially in environments where unwanted content remains a concern.
