How long is facial data kept? This matters for my contracts and client assurances.

Per the terms of service, facial features may be extracted into non-reversible embeddings for recognition purposes, and those embeddings may be retained for analytics or performance improvement. Photos themselves are kept until you delete them or your account is terminated, and inactive data may be cleaned up after a reasonable period. "Non-reversible" is the key phrase for your client conversations — the stored data isn't a gallery of faces that can be reconstructed, it's mathematical embeddings used for matching. For contract-grade specifics, the privacy policy is the authoritative read.
