Common questions
How accurate is a height prediction, really?
The mid-parental height method (used by pediatricians) predicts adult height within roughly ±8-10cm about 95% of the time without a bone-age X-ray. Zenith blends it with your current growth percentile to narrow that range further, and the range gets tighter as you get closer to skeletal maturity. We show you the range, not a fake single number.
Can habits actually make me taller than my genetics allow?
No — and we'll never claim otherwise. Genetics set your realistic range. What habits like sleep, nutrition, posture and activity control is whether you land near the top or bottom of that range. That's what your daily plan and "dream height odds" are built to optimize.
Is my data private?
Your growth profile (height, parents' heights, habits) stays local to your browser and is never sent to our servers. Only your account (email, password) and Pro subscription status are stored server-side, so you can log in from any device. See our privacy policy for details.
