Calculator inputs
Calculations run in your browser. Our calculator code does not send the numbers you enter or your calculation results to our servers or to Google Analytics. We do not store calculation history or use cookies or local storage to save your calculations.
Google Analytics
If you accept analytics cookies, we load Google Analytics 4 to understand visits and improve the website. Before you accept, and after you reject, our analytics tag is blocked and does not send visit data to Google. Once you accept, Google receives usage information such as pages viewed, session activity, referral sources, browser and device information, and approximate location. Google Analytics uses cookies, including the _ga cookie, to distinguish visitors and sessions. This visit information is separate from the numbers entered in our calculators.
For details about Google's processing, read Google's Privacy Policy and how Google uses information from sites that use its services.
Your choices
Choose “Accept analytics” or “Reject analytics” in the cookie banner. Both choices leave the calculators available. You can reopen the banner using “Cookie settings” in the footer on any page and change your choice at any time.
We store your preference in your browser’s local storage under calcunora-cookie-consent-v1 for up to 180 days. This stores your choice and its expiry date, not your calculation inputs. If browser storage is unavailable, your choice applies to the current page and you may be asked again on another visit. Clearing browser storage resets the choice.
When you withdraw consent, we disable Analytics, remove its accessible first-party cookies for this website and reload the page to stop the previously loaded tag. This stops future collection; it does not delete information already sent to Google.
You can block or delete cookies in your browser settings. Google also provides a Google Analytics opt-out browser add-on for supported browsers. Blocking analytics does not prevent you from using our calculators.
