Ultimate Growth Charts is an educational growth-reference and calculation app for qualified healthcare professionals. It does not provide diagnosis, personalized medical advice or treatment recommendations.
Age, sex and measurements entered into the calculator are processed on your device. We do not transmit clinical measurements to our purchase-verification service. Chart reference tables and images are bundled in the app. Favorites and disclaimer acceptance are stored locally. No app account is required.
On iPhone and iPad, Apple processes the paid download. On Android, Google Play processes the one-time full-unlock purchase. We do not receive your card details. On Android, RevenueCat verifies purchase status, maintains the permanent full-access entitlement, restores purchases and completes transactions through Google Play. RevenueCat processes purchase history, an anonymous app user identifier and technical app/device information needed to provide and support this service. The RevenueCat SDK caches previously verified access on the device for offline use. Access is refreshed at startup, when the app resumes and periodically while it is running; refund handling depends on store notifications and connectivity.
Google and RevenueCat process requests needed to operate purchase verification. Their policies are available at Google Privacy Policy and RevenueCat Privacy Policy. Hosting infrastructure may process connection information such as IP addresses. We do not use advertising trackers or clinical analytics. RevenueCat also uses purchase records for purchase analytics and reporting. We do not sell clinical information or purchase records.
For Android store reviewers who enter a promo code, Firebase uses anonymous authentication and app attestation to verify access. Our Firebase project stores a temporary access grant and rate-limit records tied to the anonymous identifier and a protected hash of the connection IP address. The plaintext promo code is not stored in the app, Firestore or application logs. The device stores a signed, expiring receipt in secure storage. Temporary records expire; administrative revocation records may be retained to prevent reopening revoked access. Hosting infrastructure may process connection metadata. Clinical measurements are not transmitted to Firebase. See Firebase privacy information.
PDFs are generated on your device. When you choose to print or share a PDF, the selected printer, app or service receives its content under its own privacy practices. Check the contents before sharing. Links to Shark Clinic, reference publications and our website open external services whose policies apply.
Local preferences remain until cleared or the app is removed. Purchase cache and secure reviewer-storage retention can vary with the operating system and its backup settings. RevenueCat purchase-verification records are retained for as long as necessary to support permanent access, purchase restoration, fraud prevention and applicable obligations. Contact us to request access, correction or deletion of records we control. Deleting verification records may affect offline access and support; restoring through Google Play can recreate purchase verification records. Apple and Google control their own transaction records.
This app is intended for professional use rather than independent use by children. Clinical information is not sent to our servers. Purchases use store payment systems and HTTPS verification. No security system can guarantee complete protection.
