The photos you take of your clothes never leave your device. Background removal runs on the device, frame by frame, using Apple's Vision framework. The app needs the photo to do its job, and the job stays local.
Your wardrobe — items, tags, outfits, wear log — sits in a private iCloud database tied to your Apple ID. Apple's CloudKit handles the sync. I cannot read it. Apple cannot read it either, except in the aggregate ways CloudKit needs to do its server-side work.
AI Stylist and Outfit Suggestions ask whichever AI provider you've configured. Apple Intelligence runs on-device. The on-device LLM (the one-time MLX-backed unlock) also runs on-device. If you've picked a cloud provider with your own API key, your prompt — a description of items, not the photos themselves — goes to that provider under their terms. The cloud providers don't get your closet photos.
Web Import: when you paste a product URL, Closet fetches that URL directly from the public web and parses the page locally. No part of that fetch goes through me. The product images that get saved are stored on your device, same as photos you take.
