Privacy Policy

The short version

Your measurements never leave your browser. The Shape Finder calculator runs entirely on your own device. When you enter your underbust and bust, the math happens locally, in the browser, and the result is shown to you. Nothing you type into the calculator is stored on our servers or transmitted anywhere. When you close or refresh the page, those numbers are gone.

What we do not collect

• We do not store or transmit your body measurements.
• We do not ask for your name, email, phone number, or address.
• We do not require you to create an account, and there is nothing to log in to.
• We do not knowingly collect any personally identifying information (PII).

What is handled

To keep the site running and supported, two kinds of data are processed, both through cookies and similar technologies:

• Anonymous analytics. We look at aggregate, non-identifying usage — things like how many people visited a page or which pages are popular — so we can fix problems and improve the content. This is not tied to your measurements or to you personally.
• Advertising. The site is ad-supported, and our advertising partners may set cookies to serve and measure ads. These cookies are operated by those third parties under their own privacy policies.

Cookies and your choice

When you first visit, a consent banner appears. You can accept or reject analytics and advertising cookies. If you reject them, the calculator still works exactly the same way — remember, it runs in your browser and needs nothing from us to produce your size. You can also clear or block cookies at any time using your browser’s settings, and most browsers let you opt out of cookies entirely.

Third-party advertising, in plain language

Because we show ads, some content on our pages comes from third-party ad providers rather than from us. Those providers may use cookies or similar technology to decide which ads to show and to measure whether ads were seen. We do not share your measurements with them — we could not, since we never receive your measurements ourselves. What those advertising partners collect, and how they use it, is governed by their own privacy policies, which you can review and where you can usually adjust your ad-personalization settings.

Children

Shape Finder is a general-audience informational tool and is not directed at children, and we do not knowingly collect information from them.

Updates and corrections

This policy is maintained by the Shape Finder editorial team and reflects how the site works today. If our data practices change, we will update this page. Readers can flag anything that looks inaccurate for review. Last verified: June 2026.
