How can we help?
Answers to the most common questions about TallUp — the 30-day plan, your height estimate, your account and data, and how to reach the team.
Frequently asked questions
Everything you need to know before your first workout.
Does TallUp really make you taller?
No app can guarantee you will grow taller — your final height is mostly determined by genetics and growth plates. What TallUp does is help you build daily stretching, posture, sleep and nutrition habits that support healthy growth while you are still growing, and help you stand taller by improving posture and spinal mobility at any age. The adult-height figure in the app is an estimate only, based on population growth statistics — not medical advice.
Who is TallUp for?
TallUp is designed for teens and young adults aged 13 and up who want to build healthy posture, stretching, sleep and nutrition habits. It is not a medical product, and it is not intended for children under 13.
How does the 30-day plan work?
Each day you get one guided workout of about 10 minutes, built from 12 spine-friendly exercises across 3 difficulty levels. Complete the daily session to keep your streak going, and check in on your progress along the way. Premium unlocks the full exercise library and custom workouts.
Do I need an account to use TallUp?
No. TallUp is local-first: your workouts, streaks and check-ins live on your device, and the app works without an account. Creating an account is optional and only needed if you want cloud backup or to sync your progress between devices.
What data does TallUp collect?
By default your data stays on your device. If you choose to create an account, only the information needed for backup and sync is stored on our servers. Full details on what we collect, why, and how long we keep it are in our Privacy Policy.
How do I delete my account or my data?
You can delete your account and all associated cloud data at any time from within the app, or follow the step-by-step instructions on our Delete Account page. Deleting removes your account and backed-up data from our servers; local data is removed when you delete the app.
How does Premium work, and how do I cancel?
Premium unlocks the full exercise library, custom workouts and advanced stats. See current pricing in the app. Subscriptions are billed and managed through your app-store account — you can cancel or change your plan anytime in your Apple ID or Google Play subscription settings, and Premium stays active until the end of the current billing period.
Does TallUp work offline?
Yes. TallUp is local-first, so your daily workouts, streaks, sleep logs and check-ins all work without an internet connection. You only need to be online to create an account, back up your data, or manage a Premium subscription.
How does the height estimate work?
During onboarding you enter your age, current height and your parents' heights. TallUp uses these to produce a personal adult-height estimate based on population growth statistics. It is a statistical estimate for guidance and motivation only — not medical advice — and individual growth can vary widely.
