“Based on your consent, we may collect and use your biometric information for safety, security, and identification purposes,” the privacy policy reads. It doesn’t include any details on what kind of biometric information this includes — or how X plans to collect it — but it typically involves fingerprints, iris patterns, or facial features.

The lawsuit alleges that X “has not adequately informed individuals” that it “collects and/or stores their biometric identifiers in every photograph containing a face” that’s uploaded to the platform.
