Your privacy matters to us. This policy explains how CalculatorHub handles your information.
🔒 Summary: CalculatorHub does not collect, store, or sell your personal data. All calculations happen entirely in your browser. We use Google Analytics for anonymous traffic data and Google AdSense for advertising. You can read the full details below.
Welcome to CalculatorHub ("we," "us," or "our"), accessible at calculatorhub.website. We are committed to protecting your privacy and ensuring a safe, trustworthy experience on our platform.
This Privacy Policy describes what information we collect when you visit CalculatorHub, how we use that information, and your choices regarding your data. By using our website, you agree to the practices described in this policy.
CalculatorHub is a free online calculator platform offering 80+ tools for finance, health, education, real estate, business, and utility purposes. Our core service — the calculators themselves — requires no personal information and stores nothing on our servers.
CalculatorHub does not require you to create an account or provide personal information to use our calculators. If you contact us by email (at support@calculatorhub.website), we will receive:
We use this information only to respond to your inquiry and will not use it for marketing or share it with third parties.
When you visit CalculatorHub, certain information is collected automatically by our analytics and advertising partners (Google). This includes:
This information is collected in aggregate, anonymized form and is used to understand how visitors use our website so we can improve it.
✅ Your calculator inputs are completely private. All calculations on CalculatorHub run entirely within your web browser using JavaScript. The numbers you enter — your income, loan amount, weight, or any other values — are never sent to our servers, never stored in a database, and never accessible to us or any third party.
When you use our EMI calculator and enter your loan amount, when you use our BMI calculator and enter your weight, or when you use our income tax calculator and enter your salary — that data exists only in your browser's memory and is discarded the moment you close or refresh the page.
We designed CalculatorHub this way intentionally. Financial and health data is sensitive and personal. We believe users should be able to make calculations without worrying about their data being collected, stored, or misused.
We use Google Analytics 4 (GA4) to understand how visitors use CalculatorHub. Google Analytics helps us answer questions like: Which calculators are most popular? Do users primarily visit on mobile or desktop? Which countries do our users come from?
Google Analytics collects anonymized usage data using cookies and similar technologies. Key points:

Our ads.txt file (accessible at calculatorhub.website/ads.txt) lists all authorized digital sellers for our advertising inventory, in accordance with the IAB Tech Lab's Authorized Digital Sellers specification.
We do not control the content of advertisements displayed by Google AdSense. We do not sell, share, or disclose your personal data to advertisers.
