Privacy Policy

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 don't run any analytics of our own. When a page loads ads, Google AdSense receives the standard information your browser sends with any web request, such as your IP address, browser type and the address of the page - see Advertising below.

Cookies: This site doesn't set any cookies of its own. Google AdSense, which shows the ads that keep the calculators free, may set cookies and use similar technologies - see Advertising below. To let the calculators work offline, your browser may also keep a cached copy of our pages and scripts on your device; this contains no personal data. You can clear both through your browser settings.

3. How We Use Your Information

• To provide and maintain our calculator services
• To improve and optimize our website functionality
• To detect and prevent technical issues

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 use Google AdSense to show ads (see Advertising below). We don't use any third-party analytics services; if that changes, this policy will be updated first.

6. Advertising

This site uses Google AdSense to display advertising, which helps fund the free calculators. Google and its partners may use cookies and similar technologies (including the DoubleClick cookie) to show ads based on your visits to this site and other sites on the internet, and to measure how ads perform.

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, Google's consent message asks for your choice before personalized ads are shown, in line with Google's EU User Consent Policy. You can change your choice at any time using the privacy settings link the message provides.

7. Your Privacy Rights

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

Our services are not directed to individuals under the age of 13. We do not knowingly collect personal information from children under 13.

9. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new privacy policy on this page and updating the "Last Updated" date.

10. Contact Us

If you have any questions about this privacy policy or our privacy practices, please email [email protected].

11. Data Processing

Client-Side Only: All calculator computations are performed entirely on your device using JavaScript. No calculation data is ever sent to our servers or any third party, including our ad provider. Your financial, health, and personal data entered into calculators stays in your browser - the numbers are only added to a link when you choose Copy link or a share button.
