Privacy Policy
Last updated: November 12, 2026
This Privacy Policy explains how Calcora handles information when you use its calculators and optional account features.
Calculator inputs
Calculations are performed in your browser. The values you enter into calculators are not sent to a Calcora server by this site.
Browser storage and offline access
Calcora may store your favorite tools, theme preference, selected display currency, and cached exchange-rate responses in your browser’s local storage. The website’s service worker may also save site files in your browser cache so pages can load more quickly or remain available offline. You can remove these items by clearing the site’s data in your browser settings.
Currency exchange provider
If you use the Currency Converter or open a calculator that loads currency choices, your browser requests exchange-rate data from ExchangeRate-API. The request includes the selected currency code and standard connection information, such as your IP address. Your entered amount is not included in this request. ExchangeRate-API has its own terms and privacy information.
Optional accounts and authentication
Creating an account is optional. If you sign up or sign in, Firebase Authentication (provided by Google) processes your email address, password credentials, account identifier, sign-in activity, and email verification or password reset requests to operate the account. Calcora does not receive or store your password. Firebase may send account verification and password reset emails. If you choose Google or Apple sign-in, those providers and Firebase process the account information needed for authentication. Calculator values remain processed in your browser and are not sent to Firebase by the calculators. Review Google Firebase privacy information for details about Google processing.
Analytics and advertising
Calcora does not initialize Google Analytics or include an advertising service in the current site code.
Changes and questions
This notice may be updated when the site’s features change. For questions, see the Contact Us page.
