Private by design, plain about the boundary.

Free Reading sends birth date, birth time, and the female/male selection through KAHEI’s secured calculation service only long enough to calculate and return the chart and reading. Nothing else about you is collected or sent.

The female/male selection is a Four Pillars calculation convention: it decides whether the Da Yun sequence runs forward or reverse. It is not stored, not treated as gender identity, and never enters analytics, the result URL, or the share card.

KAHEI does not persist Free Reading birth details to storage, application logs, or analytics, and does not place them in the result URL.

So that a reload or a return from the share sheet does not discard your reading, the finished result is kept in your browser tab’s own session storage. It holds the calculated chart and the written reading only — never your birth date or birth time — it is never sent back to KAHEI, and it is discarded when you close the tab or select Start Over.

The share card is designed not to include birth date, birth time, Reading Codes, identifiers, or permanent personal result URLs.

The waitlist is separate from Free Reading. If you submit it, KAHEI may store your email address, selected interest type, and any note you choose to provide.

The waitlist asks you not to include birth details, payment information, or private personal history.

Waitlist records are kept until you ask for removal or KAHEI retires the list, whichever comes first. Ask at any time and the record is deleted rather than archived.

For access questions, Reading Code recovery, or deletion requests, contact support@kahei.com.

The Free Reading and the waitlist are protected by Cloudflare Turnstile, which checks that a submission comes from a person rather than a script.

Turnstile receives the verification signals it needs for that check and returns a single-use token. KAHEI sends it no birth details, no email address, and no reading content, and does not use it to identify or track you across visits.

KAHEI currently ships direct Google Analytics 4 gtag.js. The public fallback Measurement ID is G-72CNTYLLT5.

KAHEI configures GA4 page-view measurement and a small governed set of route and waitlist events. Advertising storage, ad user data, and ad personalization are denied in the browser configuration.

KAHEI does not add advertising pixels, replay tools, fingerprinting, or a separate analytics provider. GA4 may use its normal analytics storage; KAHEI does not add other cookies or pixels. Custom Free Reading analytics transmission remains disabled.

KAHEI does not sell personal data. Public payment collection is not active in the current public experience.

Free Reading does not collect card details, create checkout sessions, call live AI, create paid reports, or create accounts.
