Privacy Policy
Effective September 13, 2026.
Short version
Core calculators run in your browser. You do not need an account. We do not currently use advertising cookies or third-party analytics scripts on this site.
Local browser storage
Some interactive tools may use localStorage to remember settings or build progress on your device. That information is not sent to our server by the tool itself. You can clear it through your browser settings.
Server and security logs
Our hosting and security provider may process standard request information such as IP address, user agent, requested URL and timestamps to deliver and protect the website. Retention and processing can depend on provider configuration and legal requirements.
Contact
If you email us, we receive the information you choose to send and use it to answer your request.
Future analytics or advertising
If we add analytics, advertising or other technologies that materially change data collection, we will update this policy and add consent controls where legally required before enabling them.
