Privacy
Your calculation inputs stay in your browser.
Calculation data
Calculator24 performs calculations in your browser. It does not require an account and does not send the values entered into calculator fields to a Calculator24 application server for processing.
Analytics and infrastructure
Google Analytics 4 measures aggregate usage such as page views, device class, approximate geography, and interactions. Google may set or read identifiers according to its own policies. Cloudflare delivers the site and may process standard request data such as IP address, browser details, requested URL, security signals, and timestamps to operate and protect the service.
Browser storage
Favorites, color theme, and text-size choices are stored locally on your device. Comparison cards last for the current page session. You can remove this data through your browser's site-data controls.
Actions you choose
Copy link places the current inputs in the page URL. Share and WhatsApp send a result summary to the service you select. Printing or downloading creates output on your device. Use these actions only for information you intend to disclose.
Your choices
You can block or delete cookies and site storage through your browser. Privacy extensions and browser settings may also limit analytics. Calculator24 remains usable without an account, favorites, or saved preferences.
Children and sensitive information
The site is a general-purpose utility and is not directed to children under 13. Avoid entering names, account numbers, medical record identifiers, or other personal information; the calculators do not need them.
Questions
Privacy or correction questions can be sent through the email listed on the About page. This policy may change when the service or its vendors change; the effective date above identifies the current version.
