Privacy Policy

Your Data Stays in Your Browser

CalcHub is a 100% client-side application. All calculations happen entirely in your web browser. No calculation data, inputs, or results are ever sent to our servers or any third party. We do not store, collect, or process any of your financial, health, or personal calculation data.

What We Collect

We use the following third-party services that may collect anonymous usage data:

• Google Analytics (GA4): Anonymous page views, session duration, device type, and approximate location (country level). No personally identifiable information is collected.
• Google AdSense: May use cookies to serve relevant ads. You can opt out of personalized ads at Google Ad Settings.

Currency Detection

CalcHub detects your local currency using your browser's timezone setting (e.g., Asia/Kolkata → INR). This detection happens entirely in your browser using JavaScript. No location data is sent to any server.

Currency Converter Rates

The Currency Converter fetches live exchange rates from the European Central Bank via the Frankfurter API. This request is made from your browser directly to the API. CalcHub does not proxy or log these requests.

No Accounts or Signup

CalcHub does not require any signup, login, or account creation. We do not collect email addresses, names, phone numbers, or any personal information. There is no user database.

Cookies

CalcHub itself does not set any cookies. However, Google Analytics and Google AdSense may set cookies for analytics and advertising purposes. You can manage cookie preferences in your browser settings.
