Almost nothing to say.

01 — No accounts. There is nothing to sign up for, so there is no email, no password, and no profile of you anywhere.

02 — No cookies, no trackers, no ad-tech. The host reports only anonymous request counts; nothing identifies you.

03 — Your birth data stays on your device. The charts are computed in your browser and the data is discarded when you leave. It is never transmitted and never stored.

04 — Sharing is a link, not a record. If you share a chart, the data lives encoded in the link itself — nothing is kept on a server.

05 — Questions: babushacc on X.
