Browser processing
In the reviewed implementation, all three tools’ measurements, clearances and paper settings are calculated in the browser. PDF/SVG files are generated there using browser download APIs. There is no file-upload input or application API that sends these tool inputs or generated files to a server in this implementation.
Settings are written into URL query parameters. Sharing or opening that URL exposes its settings to recipients and includes the query in page requests to the host. Do not put private information in parameter links. Clipboard access is attempted only when you click copy.
Application requests and storage
The reviewed application has no account backend, analytics integration, cookies, localStorage or sessionStorage usage. Site code and styles are served as website resources; opening and navigating pages requires network requests. The reviewed source does not load external fonts, tracking scripts or remote tool-processing services. This describes this implementation, not every browser extension or hosting-side service.
Hosting access
Page and resource requests reach Cloudflare Pages, including settings in parameter URLs. Generating files in your browser does not prevent hosting access records. Hosting data handling depends on the service configuration.
