Privacy Policy

The short version

Healthy Calculator Hub is an informational website. Our calculators run entirely in your browser — the numbers you type are not sent to us or stored on a server. We do not ask you to create an account, and we do not sell personal information. We do use standard web analytics and, once approved, advertising, both of which are described below.

Information we collect

• Calculator inputs: processed locally in your browser to produce a result. They are not transmitted to us.
• Usage data: like most websites, our host and analytics tools may record anonymised data such as pages visited, approximate location, browser type, and referring site.
• Cookies: small files used for analytics and advertising, as described below.

Cookies and advertising

We plan to display ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this and other websites.

• Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet.
• You can opt out of personalised advertising by visiting Google Ads Settings.
• You can opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info/choices.

If you are in a region covered by the GDPR or similar laws, ad partners will request consent for personalised advertising where required. You can withdraw or change your consent at any time.

Analytics

We may use a privacy-respecting analytics tool to understand which pages are useful so we can improve them. This data is aggregated and does not identify you personally.

Your choices

You can block or delete cookies in your browser settings, and use the ad opt-out links above. Blocking cookies will not stop the calculators from working, since they run locally.

Children

This site is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes and contact

We may update this policy as the site evolves; the "last updated" date above will change accordingly. Questions about privacy? Please reach us via our contact page.

This is a general template, not legal advice. Adapt it to your actual data practices and local laws (e.g. GDPR, CCPA) before publishing, and re-check Google's AdSense policies.
