Data you enter into calculators
We do not collect, transmit, or store any data you enter into our calculators.Dates, cycle lengths, weights, and all other inputs are processed entirely in your browser. They are never sent to our servers. Calculator state may be encoded in your page URL (as query parameters) for shareability — that URL is only shared if you explicitly click "Share link."

Advertising cookies are distinct from the health information you enter into our calculators, which (as noted above) never leaves your browser.

Third-party links
Our content links to external websites (medical society guidelines, government health pages). We are not responsible for the privacy practices of those sites.
