2. Calculator Data

All calculations you perform on this site are processed entirely within your browser using client-side code. The numbers and values you enter into any calculator on this site are not transmitted to our servers, not stored in any database, and not shared with any third party.

When you close your browser tab or navigate away from a calculator page, any locally processed data is gone. We have no access to what you calculated.

This information is collected for the purpose of understanding how visitors use the site, improving the tools we provide, and maintaining site security. It is not used to identify you personally.

We use Google Analytics to collect anonymous data about how visitors interact with this site. Google Analytics uses cookies and similar tracking technologies to gather information including pages visited, session duration, geographic location at the country or region level, and traffic sources.
