Calculator data and browser storage
The calculation runs in your browser. The site code does not send the length or spacing you enter to a server. When you switch languages, those values and the current result are briefly held in this tab’s session storage so the next language can restore them; the entry is removed after that switch. A shared page link does not contain your inputs.
Site requests, contact, and advertising
Loading pages and local images sends normal web requests to the hosting provider, which may process technical request data such as IP address and browser information. If you email the published contact address, your email provider and the recipient process that message. No analytics or AdSense publisher ID is configured in this build. Advertising code is designed to load only after consent and valid operator settings; this policy must be updated if advertising or analytics is enabled.
