Information we process
The calculator operates in your browser. Values entered into calculator fields may be placed in the page URL when you use a shareable result, but they are not stored in a user account. Do not enter personal or confidential information.
Our hosting provider may process standard server logs such as IP address, requested URL, browser identifier, timestamp and security events for delivery, abuse prevention and troubleshooting.
Analytics and advertising
We may use Google AdSense and measurement services. These providers may use cookies, local storage, IP addresses and device signals to deliver, limit and measure advertising subject to your region and consent choices.
Where required, a consent management platform will request a choice before non-essential advertising storage is used. You can revisit privacy choices through the privacy controls displayed on the site.
Retention and sharing
Operational logs are retained only as reasonably necessary for security and reliability. We do not sell calculator input data. Service providers process limited information under their own terms and applicable data-protection obligations.
Your choices and contact
Depending on your location, you may have rights to access, correct, delete or restrict personal information. Contact us using the address on the contact page. We may request reasonable verification before responding.
