Privacy Policy

Welcome to Calculator Hub. This Privacy Policy explains how our website and its suite of more than fifty free online calculators handle information while providing fast, secure, and mobile-friendly calculation tools. Our calculators such as EMI, mortgage, compound interest, BMI, calorie, GPA, and unit converters are built to process inputs directly inside your browser without sending any sensitive data to our servers.

1. Information We Collect

We prioritize user privacy. All essential calculations happen locally within your device, and no personal, financial, mathematical, or health-related inputs are stored on our servers. Any recent results or preferences you see are saved only in your browser using local storage and never transmitted externally.

2. Technical Information

We may collect limited technical information such as anonymized IP addresses, browser type, interaction patterns, and performance metrics strictly to improve speed, accuracy, security, and overall site reliability. This information is processed in aggregate and cannot identify individual users. We do not sell or trade any data with third parties.

3. Cookies and Local Storage

Cookies and local storage are used to enhance user experience—such as remembering dark mode settings, improving load speeds, analyzing general traffic trends, and maintaining a smooth browsing experience. You may disable cookies through your browser settings, but doing so may affect the performance of certain calculators.

4. Third-Party Services

Our site may rely on trusted third-party services for analytics, performance monitoring, hosting, or advertising. These partners follow standard privacy protections and process only non-personal, aggregated data. We maintain strict controls to ensure your sensitive calculator inputs remain private and on-device.

5. Children's Privacy

Calculator Hub does not knowingly collect personal information from children under 13. If you believe such information has mistakenly been collected, please contact us immediately so we can resolve the issue.

6. Your Rights

You may contact us anytime to request clarification regarding how your anonymous usage data is processed or to ask any privacy-related questions. Our support email is support@calculatorhub.com.

7. Policy Updates

We may update this Privacy Policy from time to time to reflect new features, regulations, or improvements. Any changes will be posted on this page with an updated date. By continuing to use Calculator Hub, you accept and agree to the updated Privacy Policy.
