## 1. Who we are

This privacy policy applies to **bmicalculatorsystem.com** (the "Site"), a free online
Body Mass Index calculator. It explains what information is — and isn't — processed
when you use the Site.

## 2. Your calculator inputs never leave your device

The height, weight, age, and any other values you enter into the calculator are
processed **entirely within your web browser** using JavaScript. They are never
transmitted to our servers, never logged, never stored, and never shared. When you
close or reload the page, your inputs are gone. We have no technical ability to see
what you typed.

## 3. Information we do not collect

The Site does not:

- Require an account, registration, or sign-up of any kind
- Collect names, email addresses, or other personal identifiers
- Store or transmit your calculator inputs (height, weight, age)
- Sell or rent any data to data brokers

## 4. Server logs and hosting

Like virtually every website, the Site is delivered by a hosting provider whose
infrastructure may automatically record standard technical logs — such as your IP
address, browser type, the pages requested, and timestamps — for security, abuse
prevention, and operational purposes. These logs are not used by us to identify
individuals.

## 5. Third-party resources (web fonts)

The Site loads its typefaces from Google Fonts. When your browser fetches these font
files, your IP address and standard request headers are transmitted to Google's
servers, governed by the Google Privacy Policy
(https://policies.google.com/privacy). No other third-party scripts, analytics, or
embeds are present on the Site.

## 6. Advertising (Google AdSense)

The Site is supported by advertising served through **Google AdSense**. Google, as a
third-party vendor, uses cookies to serve ads, including the DoubleClick/DART cookie.
Ad personalization is governed by Google, not by us. You can control this:

- Opt out of personalized advertising in Google Ads Settings
  (https://adssettings.google.com)
- Opt out of third-party vendors' personalized ads at aboutads.info
  (https://www.aboutads.info/choices)
- Read how Google uses data from sites that use its services at
  https://policies.google.com/technologies/partner-sites

Visitors in the EEA, the UK, and Switzerland are shown a consent message before any
advertising cookies are set, as required by the GDPR and ePrivacy rules.

## 7. Cookies and local storage

The Site itself sets no cookies — no analytics, no session cookies, no fingerprinting.
The only cookies you may encounter are the advertising cookies described in section 6.

## 8. Children's privacy

The Site is intended for general audiences and is not directed at children. We do not
knowingly collect personal information from children under 13.

## 9. Your rights

Under regulations such as the GDPR (EU/UK) and CCPA (California), you have rights over
personal data a service holds about you. We do not ourselves collect or store personal
data, so there is no data held by us to access, correct, or delete.

## 10. Changes to this policy

If our practices change, we will update this page and revise the "Last updated" date
above before the change takes effect.
