AI scan processing on iPhone
iPhone Build 48 uses AI processing for completed four-photo scans. Before the first upload, the scan screen says that Pip will send four photos, height, weight, age range, and sex, names OpenAI and Modal, explains that Modal receives the full photos including face, hair, and surroundings, and labels the results as AI estimates rather than medical measurements. If your weight came from Apple Health, the disclosure says so. Nothing is uploaded until you choose “Agree & start scan”.
Body analysis
Pip prepares a separate analysis copy of each photo on your iPhone by removing metadata and background and masking the head. Those four prepared images, plus your entered height, weight, age range, body-sex answer and the source of the weight, travel through Pip's Railway service to OpenAI. OpenAI returns bounded exterior-body estimates and visible-shape observations. Pip does not send your name, treatment log, symptoms, notes, or Journey entries with the body-analysis request.
Fitted 3D body
A second process sends metadata-stripped copies of the four full photos through Railway to Pip's private Modal service to create the fitted 3D body. These copies can include your face, head, hair, clothes, and visible surroundings. The staged source-photo bytes are removed from the avatar service after processing. The derived 3D result and necessary anonymous job record remain available until you delete the scan or withdraw consent.
Pip uses anonymous installation and request identifiers to protect these calls and record consent or deletion. The body-analysis service does not keep the submitted photos or result content in Pip's database. OpenAI requests are configured with store: false; OpenAI may still retain limited abuse-monitoring data under its applicable service terms.
