Calculations are private
Every calculator on Calculator runs entirely in your browser. The numbers you enter are never transmitted to or stored on our servers.
Local storage
We may store small, non-personal preferences on your device - such as your theme choice and a short list of recently-used calculators - using your browser's local storage. This never leaves your device and contains no personal information.
Analytics & advertising
We may use privacy-respecting analytics to understand which calculators are popular, and we may display advertising (for example, Google AdSense) to keep the service free. Third-party ad providers may use cookies in line with their own policies; you can manage cookies in your browser settings.
