Privacy Policy

Introduction

Body Visualizer ("we", "our", or "the service") is a free, browser-based body shape visualization tool available at body-visualizer.net. This policy explains what information we handle when you use the service.

The short version: we do not require accounts, we do not store your measurements, and we do not ask for photos.

What We Do Not Collect

• No photos. This tool works entirely from numeric measurements you enter manually. You are never asked to upload or capture an image.
• No accounts. No sign-up, no email, no login, no password.
• No measurement storage. The height, weight, chest, waist, hips, and inseam values you enter are processed in your browser to render the 3D preview and compute metrics. They are not written to any database tied to you.

What Happens to Your Measurements

1. Local preview rendering. Your inputs drive the 3D model and the BMI / Waist-to-Height / Waist-to-Hip / Body Fat estimate displayed on the page. This calculation runs in your browser.
2. Optional AI analysis. If you click the "Analyze" button, your numeric measurements (height, weight, chest, waist, hips, inseam, and sex) are sent to our server, which forwards them to the Gemini 3 large language model to generate a written explanation. The response is returned to your browser. We do not store the request body or the response on a per-user basis.
3. No identifiers attached. Requests are not tied to a user account, email, or persistent identifier we control.

AI Model

To generate AI analysis text, we use Google's Gemini 3 large language model. We send only the numeric measurements and sex you entered — no name, email, IP-linked identifier, or photo. The model provider may log requests under its own privacy terms.

Cookies and Local Storage

• We use local storage in your browser to remember non-personal UI preferences (e.g., theme, locale). This data never leaves your device.
• We may set a UTM-tracking cookie if you arrive via a marketing link, used only in aggregate for traffic analytics.
• We do not use third-party advertising cookies.

Analytics

We may use privacy-respecting analytics (e.g., page views, country-level traffic) to understand which pages are visited. Analytics never include the measurements you entered into the tool.

GDPR and CCPA Privacy Rights

Body Visualizer is designed to minimize personal data collection. Because the core tool does not require an account, email address, photo upload, or stored measurement profile, we usually cannot identify a visitor from body measurements entered during a session.

If privacy laws such as the GDPR, UK GDPR, or CCPA/CPRA apply to you, you may contact us to ask about access, correction, deletion, portability, objection, restriction, or opt-out rights for any personal information we may hold. We will respond based on the information available to us and the requirements that apply to the request.

We do not sell personal information, and we do not use the body measurements entered into the visualizer for cross-context behavioral advertising.

Children's Privacy

Body Visualizer is intended for general informational use. It is not designed for children under 13, and it should not be used for clinical assessment of minors. Parents and guardians should supervise any use by minors.

Not Medical Advice

The visualizations and metrics produced by Body Visualizer are informational estimates. They are not medical advice, diagnosis, or treatment, and they should not be used to make health decisions or to assess eating disorders.

Changes to This Policy

We may update this policy from time to time. The "created_at" date at the top of this page reflects the most recent revision.
