1. Introduction

Welcome to Smart Calculator Hub ("we", "our", or "us"). We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we handle your information when you use our calculator tools.

2. Information We Collect

Calculator Input Data: All calculations are performed entirely in your browser. We do not collect, store, or transmit any data you enter into our calculators.

Usage Data: We do not currently run any analytics or tracking scripts on this site. If we add anonymous usage analytics in the future (for example, to see which calculators are most used), we will update this section first.

Cookies: We use a local cookie-consent preference and may use essential cookies to improve your experience. You can control cookies through your browser settings.

3. How We Use Your Information

4. Data Security

All calculations are performed locally in your browser. We implement appropriate security measures including HTTPS encryption, security headers, and regular security updates to protect our website.

5. Third-Party Services

We do not currently use any third-party analytics services. If we do in the future, those services may collect information sent by your browser as part of a web page request, such as cookies or your IP address, and this policy will be updated accordingly.

6. Advertising

This site uses, or intends to use, Google AdSense to display advertising. Google and its partners use cookies and similar technologies (including the DoubleClick cookie) to serve ads based on your prior visits to this website and other sites on the internet. This helps fund the free calculators on this site.

You can learn more about how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and you can opt out of personalized advertising by visiting Google Ads Settings.

If you're located in the European Economic Area, the United Kingdom, or Switzerland, you'll be asked to provide or decline consent before we show personalized ads, in line with Google's EU User Consent Policy.

You have the right to:

• Access any personal data we may hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Control cookie preferences, including ad personalization via Google Ads Settings

8. Children's Privacy
