Privacy on this site

This site sets no cookies and runs no analytics. There is no tracking script, no pixel, and nothing to consent to.

The pinyin table and the tone drill run entirely in your browser. Nothing you tap is sent anywhere, because there is no server to send it to.

The typefaces are served from this domain, not from a font CDN, so loading a page does not tell a third party that you visited.

The app, when it ships, is a separate matter with its own privacy policy. Raw recordings are never stored: audio arrives, is scored, and is deleted.
