What Size? is designed as a local-only clothing size guidance app. The app helps you save your measurements, compare them with bundled retailer size guide data, and keep private notes about how clothes fit.
We do not collect, sell, track, or share your personal data. Your measurements and fit notes stay on your device unless you choose to manage them through Apple’s own device features, such as backups or paired-device services.
Information Stored On Your Device
The app may store the following information locally so it can provide size guidance:
- Body measurements you enter, such as height, bust, waist, hips, and inside leg.
- Your unit preference, such as centimetres or inches.
- Saved shortlist items and personal fit memory notes that you create in the app.
- App settings needed to remember your choices.
Information We Collect
We do not collect data from the app. In this policy, “collect” means transmitting data off your device in a way that allows us or a third party to access it for longer than needed to service a request.
Apple Intelligence
If Apple Intelligence fit summaries are available on your device, they use Apple’s on-device Foundation Models framework. The app’s deterministic sizing engine remains the source of truth, and Apple Intelligence is used only to rewrite guidance into a more conversational explanation.
Apple Watch
The Apple Watch companion app can receive a private WatchConnectivity snapshot from the iPhone app so it can show quick size guidance. This paired-device sync is between your own devices and is not sent to us.
Speech Features
Measurement guides may use Apple text-to-speech voices to read steps aloud. The app does not record your voice.
Retailer Links
The app may include links to retailer size guide pages. Opening those links may take you to a third-party website, and that website’s own privacy policy will apply.
Third-Party Services
The app does not include third-party analytics, advertising networks, login SDKs, or crash-reporting SDKs.
Deleting Your Data
You can remove saved measurements, shortlist items, and fit memory within the app. Deleting the app from your device also removes the app’s local data from that device, subject to any device backups you manage through Apple.
Children’s Privacy
The app is not designed to collect personal data from anyone, including children.
Changes To This Policy
If the app’s privacy practices change, this policy will be updated to explain those changes.
