How is facial data processed and stored? This is the part that makes some clients nervous.

Per the terms, facial features may be extracted into non-reversible embeddings used for recognition. That's an important distinction: the system isn't storing a folder of cropped faces that someone could browse — it's storing mathematical embeddings derived from the faces, which can be compared but can't be reversed back into images. Those embeddings may be retained for analytics or performance improvement. For clients asking the tough questions, "non-reversible embeddings, not face photos" is the accurate and reassuring answer.
