Birth information
Your birth date, optional birth time, and timezone are sent over HTTPS to calculate a chart. They are processed in server memory and are not inserted into our analytics database. The resulting chart and reflection are not stored by us.
Anonymous operational data
We keep allow-listed events such as page view, tool start, chart success, print, share, and error. Records may include page path, fixed campaign labels derived from allow-listed utm_source, utm_medium, and utm_campaign values or a small allow-list of known referral domains, a random session identifier stored for the browser session, user agent, timestamp, and a one-way hash of the network address. Raw referrer URLs and other query parameters are discarded before an event is sent. The hash is used for rate limiting and cannot be used by the site to recover the original address.
Browser storage and exports
The pilot uses session storage for a random analytics session identifier. It does not create an account or save birth details in local storage. Printing or saving a PDF is handled by your browser. A share card is generated locally in your browser as a PNG and contains the Four Pillars, Day Master, method label, and site address—not the birth date, birth time, or birthplace timezone. If you choose the system share option, your operating system and selected destination app handle the exported card under their own terms.
Infrastructure
The site is delivered through Cloudflare and an origin server operated for SailToWorld. Those providers may process standard network logs under their own terms. Cloudflare Web Analytics collects page-view and performance metrics without cookies or browser storage; the beacon is not configured with birth or chart form fields. We do not sell birth details or chart results.
Retention and requests
Anonymous operational records are kept only as long as needed to evaluate and protect the pilot. Because no account or birth record is created, we generally cannot identify a chart request as belonging to a particular person. Questions can be sent through the SailToWorld contact page.
