Face swapping should use images from consenting adults or licensed fictional assets. Do not create deceptive, sexual, harassing, defamatory, identity-fraud, or nonconsensual content, and never involve minors in sexualized transformations. Clearly label synthetic output where viewers could mistake it for authentic media. Inspect alignment, skin tone, lighting, occlusion, hair, teeth, and frame consistency. Protect biometric images, minimize retention, and honor deletion requests. Keep the originals and editing record.
