Body-metric tools that respect your privacy

How it works

There is no sign-up step and no upload step, because there is nothing to sign up to and nowhere for the numbers to go.

1. Enter your numbers. Height, weight, age, measurements — whichever the tool needs. Metric or imperial; every tool switches between them.
2. Read the result with its working. Each tool names the published formula or standard it used, so the number is something you can check rather than something you have to take on trust.
3. Keep it, if you want to. Tools that track — the progress tracker, the habit tracker, the body-fat log — save to your own browser's storage. Nothing is kept unless you choose to save it, and you can clear it whenever you like.

Why it all runs in your browser

Every calculation runs in your browser, and anything you save is stored on your own device. The figures you enter — weight, measurements, goals — are never uploaded, and no server here ever receives them.

This site is funded by ads. Ads are not switched on yet; when they are, Google and its partners may set cookies and collect data about your visit under the consent you give, and that is disclosed in full on the privacy and cookie pages. Your calculator inputs are not part of that — they are never sent anywhere, either way.

The full detail is in the Privacy Policy, theCookie Policy and theConsumer Health Data notice.

One set of inputs, 11 tools

The tools are built to feed each other rather than to stand alone. Your body-fat percentage makes the FFMI benchmark meaningful; your maintenance calories fromTDEE set the starting point formacros, for aweight-loss timeline and forrecomposition; and thedashboard derives a whole set of metrics from one set of measurements. What you learn in one tool is rarely something you have to type again.

Every number shows its working

Where an established model exists, calivue uses it and says which one: Mifflin-St Jeor for resting metabolic rate, the US Navy circumference method and waist-to-height for body composition, Karvonen for heart-rate zones, and Daniels and Riegel for running pace and race equivalence. Naming the source is what lets you compare a result against any other calculator, or against a textbook, and see why they differ.

These are population-level equations. They were derived from groups of people and they describe a group well; any single person can sit some way off the line, and none of them can see your training history, your medical context or how you slept. Treat a result as a starting estimate to be adjusted against what actually happens, not as a measurement. How we choose and review what is published here is set out in ourEditorial & Medical-Review Policy.

What calivue deliberately does not do

A body-metrics site can drift into territory where a calculator is the wrong instrument. These are settled decisions rather than gaps in the roadmap:

• No supplement or dosage guidance, and nothing about prescription medication.
• No symptom checking and no diagnosis. Nothing here interprets how you feel.
• No interpretation of clinical values — blood pressure, glucose, cholesterol and the like belong with the clinician who ordered them.
• No single "ideal" weight. Where a healthy range exists, the range is what gets shown, because a lone target number invites a comparison that is not useful to anyone.
• Nothing gamified. Streaks in the habit tracker are there to show consistency, not to be defended.
