Your details stay in your browser.
The short version: we don't want your data, we don't ask for an account, and your weight, height, age, and intake never leave your device. Use this page like you would a paper worksheet.
What we don't collect
- No account, no email, no name, no phone number.
- Your inputs — weight, height, age, sex, activity, intake, and goal — are processed entirely in your browser. They are never transmitted to our servers.
- We don't sell, share, or rent any user data — we don't have any to sell.
What we do collect
Anonymous usage analytics. We use Cloudflare Web Analytics, a cookieless, privacy-first tool that measures aggregate traffic and performance (page views, browser type, country from IP — not stored). It sets no cookies, stores no personal data, and doesn't track you across sites. Because it's cookieless it runs for all visitors and needs no consent — it isn't tied to the Analytics toggle in the cookie banner.
Advertising
This site is free because it's supported by display advertising. Our advertising partners may set their own cookies on your device to serve relevant ads and measure performance. We never share any health information you enter — your weight, intake, or any other input — with advertising or analytics partners. You can opt out of personalized advertising via aboutads.info or your browser's privacy controls.
EU, UK, and Switzerland visitors see a consent prompt before any non-essential (advertising) cookies are set. Our cookieless analytics measure aggregate traffic only and run without a prompt. You can review or change your cookie choices at any time — .
California residents
California residents have the right to opt out of the "sale" of personal information. Under CCPA's broad definition, our use of behavioral advertising cookies may qualify. To opt out, use the cookie controls above or enable the Global Privacy Control (GPC) signal in your browser — we honor GPC.
Deleting your data
Because we don't store anything server-side, the only place your inputs exist is on your device (in your browser's local storage, so the tool remembers your last entry). To delete it, clear your browser's site data for whenwilliplateau.com.
Children
This site is not directed to children under 13, and we do not knowingly collect any information from children.
Third-party links
Links to sources such as the NIH, NIDDK, and PubMed lead to their own websites; we don't control or speak for their privacy practices.
