Your calculations stay on your device

Your choice of light or dark mode is saved locally on this device. This preference contains no amounts and is not sent to a server. You can remove it by clearing the website data in your browser.

The calculator runs in your browser. Entered amounts and simulation lines are not sent to a server and are cleared when you reload the page.

Copy uses your device clipboard at your request. CSV export creates a local file. You choose where to store these documents.

The website loads the Google AdSense script to prepare its review. Your browser then contacts Google, which may receive technical data such as your IP address and information about the page visited. This version does not activate advertisements. Advertising consent will be configured before ads are served. Fonts remain locally hosted; no separate analytics service is added. See Google’s privacy policy: https://policies.google.com/privacy.

During an online visit, the hosting provider may process technical data needed to establish the connection, including IP addresses and server logs. This is separate from the calculator: the website does not send entered amounts.
