Privacy Policy

Overview

MicroCalculators ("we", "us", or "our") operates microcalcs.com. This page explains what information is collected when you use our calculators and how it is used.

No Personal Data Collection

We do not collect, store, or transmit any personal data you enter into our calculators. All calculations run entirely in your browser. Numbers you type into a calculator field are never sent to our servers.

Advertising — Google AdSense

We display advertisements served by Google AdSense. Google uses cookies and device identifiers to serve ads based on your prior visits to websites. This may include personalised advertising based on your interests.

You can opt out of personalised advertising by visiting Google Ads Settings or by visiting aboutads.info.

For more information on how Google uses data when you use our site, see How Google uses data when you use our partners' sites or apps.

Cookies

We use one first-party cookie: theme, which stores your dark/light mode preference locally in your browser. No third-party tracking cookies are set by us directly. Google AdSense may set its own cookies as described in Google's privacy policy.

Local Storage

We store your theme preference (dark or light mode) in your browser's localStorage. This data never leaves your device.

Third-Party Links

Some calculator pages contain links to external websites. We are not responsible for the privacy practices of those sites.

Children's Privacy

Our site is not directed to children under 13. We do not knowingly collect information from children.

Changes to This Policy

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