Your answers do not leave this browser. The questionnaire computes everything on your device. Your run is kept in localStorage so you can continue or see the result again; the button below deletes it.

When you finish, the browser sends an anonymous summary: which nutrients made the top three, each nutrient’s score rounded to tenths, whether the thyroid card appeared, whether any red flag was ticked, the page language, and the country and region Cloudflare resolved. It is on by default and can be turned off below; the choice is remembered in this browser.

Not stored: your answers, “About you”, your IP address, city or the exact time. Rows are not linked to each other, so two runs by the same person cannot be joined. To prevent abuse the server keeps a salted hash of the address for one day, separately from the statistics.

No cookies, no third-party scripts, fonts or analytics, enforced by a Content-Security-Policy header.

If you take the questionnaire in a chatbot

In ChatGPT, Claude or another chatbot, your answers are seen by that chat service, on its terms. If the chatbot scores the result through our service (/api/score/), the answers reach us for that one calculation only: we do not store them, log them or add them to the statistics. As everywhere on the site, the server keeps only a salted hash of the address for one day, to prevent abuse.
