Effective date: July 22, 2026
The short version: TallUp is local-first. Your data lives on your device, an account is optional, we run no ads and no analytics trackers, and we never sell your data.
TallUp is a fitness and habit app that combines guided stretching, posture work, nutrition and sleep tracking, and an adult-height prediction estimate. It is general fitness software — not a medical device and not medical advice.
By default, everything you enter stays on your device in the app's local storage and never leaves it:
You can erase all of it at any time with Settings → Reset profile & progress, or by uninstalling the app.
Creating an account is entirely optional — every feature works without one. If you choose to create an account (to back up and sync your progress across devices), we collect:
We do not collect your name, contacts, precise location, photos, or device advertising identifiers.
Height, birthdate, parents' heights, puberty stage, sleep, and nutrition logs are health-adjacent. We treat them with extra care: they are used only to power features you see in the app (your plan, predictions, and charts), they are never used for advertising, and they are never shared with or sold to third parties. Without an account they never leave your device.
TallUp Premium subscriptions and lifetime purchases are processed by the Apple App Store or Google Play. We never see or store your payment card details. We use RevenueCat to manage subscription status; RevenueCat processes purchase and entitlement information tied to an anonymous app-user id (and your account id if you sign in) solely to unlock Premium features. No purchase data is used for advertising.
TallUp is designed for users aged 13 and older. We do not knowingly collect personal information from children under 13. During onboarding, a birthdate indicating an age under 13 blocks profile creation entirely. If you believe a child under 13 has provided us personal information, contact us and we will delete it promptly.
We use a small number of processors to operate the optional features above:
Each processes only the data needed to provide its service, under its own privacy policy.
All network traffic uses HTTPS/TLS. Cloud data is protected by row-level security so only you can read or write your own progress row. No system is perfectly secure, but we follow least-data principles: the less we collect, the less there is to protect.
If you use the optional account features, your data may be processed in the region where our database is hosted. By creating an account you consent to that processing. Depending on your jurisdiction (e.g. GDPR/UK GDPR, CCPA), you may have rights to access, correct, export, or delete your personal data — the in-app tools above cover access and deletion, and you can contact us for anything else.
If we change this policy we will update the effective date above and, for material changes, announce them in the app. The current version is always available at this URL and from within the app.
