Calculator inputs
Values and text entered into the tools are processed in your browser. The calculator code does not submit them to a calculation service, analytics endpoint, or advertising network. Inputs and results are not saved by the site and normally disappear on reload. Browser form restoration or autofill can behave differently according to your settings.
Page requests and hosting
Opening a page sends a normal request to the website host. The host may process an IP address, request time, user-agent information, requested path, and error information for delivery, security, and operational logging. Actual retention and processing depend on the hosting provider selected for the live website.
Cookies and external services
This version of the site does not set cookies or use local storage for tracking. It does not include advertising, analytics, external fonts, embedded media, or third-party scripts. If those services are added, this policy must be updated to describe the actual processing and any relevant choices before they are used.
Contact messages
The contact form prepares an email in your email app. It does not submit a message to a server on this page, and you review and send the message yourself. Messages sent to the operator may contain your name, reply address, and feedback. They are used to respond and address the issue, subject to applicable legal obligations.
Your questions and updates
For questions or requests about information you have supplied directly, use the contact page. The operator can respond only to information within its control; browser and hosting-provider records may be managed separately. This policy will be revised when the site changes.
