Privacy Policy

Last updated: October 2026

MacroForte ("we", "us") runs macroforte.com. Set out below is what we do with information and what you can choose. In one line: your body statistics and goal are handled inside the browser and never leave your device.

Scope of this policy

MacroForte does one thing — as a macronutrient calculator it turns body statistics and a goal into daily protein, carbohydrate and fat targets, with the option of basing the split on lean mass. It estimates energy needs from the body statistics and activity level, adjusts for the goal, then divides that energy into the macronutrient ratio of the diet mode you pick — using grams per kilogram of lean mass when the precise option is chosen. What follows concerns only that tool and the inputs involved in it.

Everything the tool works with — your body statistics and goal — is handled locally. It is usually reached for things like adjusting the split after a change of goal, and because nothing is transmitted a visitor can close the tab knowing no copy was made anywhere.

Your inputs

This site has no backend that receives what you type. The page reads your input to compute an answer, shows it to you, and forgets it — because nothing was ever sent anywhere in the first place. The arithmetic is identical regardless of who is looking at the screen.

Cookies and advertising

We set a cookie only to remember whether you have dismissed the cookie notice. Third-party advertising partners, including Google, may use cookies or similar technologies to serve ads based on your visits to this and other sites. You can control personalized advertising in your browser settings or through Google's ad settings. Blocking cookies does not affect the tool: the calculation requires none.

What our statistics cover

Usage statistics, when collected, are anonymous and aggregated. They tell us which pages are useful; they do not identify you and they never include your input to the calculator.

Health-related inputs

The health figures you supply are used for the calculation in front of you and nothing else. There is no account, no profile and no history, so nothing accumulates about your body over time.

Security and data retention

There is nothing of yours to keep, so there is no retention period to describe for calculator input: it exists only in your browser tab and disappears when you leave. The site is served over HTTPS throughout.

Children

These tools are built for a general adult audience rather than for children. We do not knowingly collect personal information from anyone under 13, and would remove it on being told.

Rights you can exercise

You may have statutory rights over personal data — to access, amend, erase or object to its processing, depending on your jurisdiction. You can exercise them by writing to us; in most cases there will be no stored data to act on.

How this policy changes

If the way we handle data ever changes, this page will be revised and the date at the top adjusted accordingly. Continuing to use the site after an update means you accept the revised policy.

Automatic technical data

Standard server logs are generated when your browser requests a page. They cover technical details like your IP address, browser, referring URL and timestamps, and are used only to keep the site running and secure. None of it is linked to the input you give the tool.
