How HeightWaist handles measurements, sharing, API requests, and contact messages.
Measurements stay private
The browser calculator performs its math on your device. HeightWaist does not store your height, waist measurements, or calculator result. The optional API evaluates requests without storing them.
Result sharing
The full calculator only prepares your reported WHtR, selected service, informal classification, and the public site link. Height, waist measurements, and sex are excluded. Sharing occurs only after you choose it.
Contact messages
The contact form uses Cloudflare Turnstile and Resend to relay messages. Contact details are used for one-to-one replies and are not added to a marketing list.
Tracking and storage
The calculator does not use cookies, analytics, local storage, session storage, or an account. Public source documents retain the terms of their original publishers.
