@JustinHeartley-8871 Thanks for the question. While the Face Service does not store customer images, the extracted face feature(s) will be stored on server. The Face ID is an identifier of the face feature and will be used in Face - Identify, Face - Verify, and Face - Find Similar. The stored face features will expire and be deleted 24 hours after the original detection call.
You can use the List person groups’s personGroupId, name, userData and recognitionModel.
