Privacy Policy

What we store

Your growth profile — height, parents' heights, age, sex, and habit answers — stays local to your device (browser localStorage) and is never transmitted to our servers. Your account itself (name, email, and a securely hashed password — we never store your password in plain text) is stored server-side so you can log in from any device and so your Zenith Pro subscription status can be verified securely. If you subscribe to Zenith Pro, Stripe (our payment processor) collects and stores your payment details directly — we never see or store your card number. We store only your Stripe customer and subscription IDs so we know your plan is active.

Deleting your data

Clear your browser's site data for this domain to remove your local growth profile. To delete your account and its data from our servers, email us at the address below and we'll process your request promptly.

Sensitive data

Height and growth data can be sensitive, especially for minors. We never sell data or share it with advertisers. Account data is hosted with a reputable infrastructure provider (Netlify); payment data never touches our servers at all and is handled entirely by Stripe, a PCI-compliant payment processor.
