Common questions
Is the prediction really free, no catch?
Yes. Your predicted height, range, growth chart and daily plan are fully free — that's the whole reason Zenith exists as an alternative to apps that paywall the result itself. Pro is optional and only adds coaching/recommendations/tracking on top.
Can I cancel anytime?
Yes — manage or cancel your subscription anytime from the "Billing" button in your dashboard. It opens Stripe's secure billing portal; no emailing support required.
Do I need an account to see my prediction?
No. Run the free prediction as a guest first — create an account only when you want to save your result or go Pro.
