TallUp stores all of your data (profile, measurements, metrics, settings) locally on your device, in a local database. Nothing is ever sent to a server. TallUp has no backend.
TallUp requires no account and collects no personal data. The app contains no analytics or tracking SDK, no advertising, and shares no data with third parties.
Adult-height estimates are statistical calculations performed entirely on your device, based on the information you enter. They are not a medical diagnosis and do not replace advice from a health professional.
Premium subscriptions are processed by Google Play Billing. TallUp itself receives no payment or identity information; Google's own privacy policy applies to the transaction.
You can permanently erase all data at any time from Settings → Erase all data, or by uninstalling the app.
TallUp is intended for users aged 13 and over, and for parents tracking their children's growth. Since no data leaves the device, no personal data of any user — minor or adult — is collected or processed by us.
