Privacy Policy
Effective date: 2026-08-01
This privacy policy applies to the Height Predictor app from Swizzle Works. It does not replace the studio website privacy policy.
Who we are
Height Predictor is published by Swizzle Works. For privacy questions, contact Swizzleworks@gmail.com.
Summary
Height Predictor is designed so that Swizzle Works collects no personal data from the app. There is no account system, no analytics or advertising SDK from us, and no Swizzle Works server that receives your inputs.
What the app does not do
- Create accounts or ask you to sign in.
- Collect, transmit, or sell personal information.
- Use analytics, advertising, or tracking SDKs.
- Require network access for the core Bayley-Pinneau lookup.
- Store clinical inputs on Swizzle Works servers (there are none for this app).
On-device use
Height Predictor runs its predicted adult height lookup on your device using tables bundled with the app. Sex, growth tempo, current height, and bone age that you enter remain on the device for that session of use. Swizzle Works does not receive those values.
If the operating system or device provides optional local persistence (for example, remembering recent inputs), that data stays on your device under Apple’s platform controls. We do not operate a backend that reads it.
Clinical reference note
Height Predictor is a clinical reference tool for users who already have a scored bone age. It is not a consumer measurement or guessing service, and it does not connect to electronic health records or hospital systems.
App stores and platform services
When you download or update Height Predictor through the Apple App Store (or another store), that platform may collect information under its own privacy policy—for example purchase, download, and crash diagnostics controlled by Apple. Those practices are not operated by Swizzle Works and are not covered by this policy.
Contact and website
If you email us for support, we receive whatever you choose to include in that message. Marketing pages on swizzleworks.com are covered by the website privacy policy.
Changes
We may update this policy from time to time. The effective date at the top of this page will change when updates are published. For App Store listings, material changes are reflected with the next app version when required.
