PRIVACY
Your curve is calculated here.
The calculator runs in your browser. This release does not send the controls or entered time to a calculation service.
Inputs and results
No login, file upload or account is needed. The calculator does not write input history to cookies, local storage or session storage. Reloading starts the default example. Text and CSV buttons create a file locally from the current valid result; the site does not upload it.
Clipboard
Copy CSS uses the browser’s clipboard API only when you press the button. Your browser may allow or deny that action. If it fails, a selectable copy field appears. A clipboard write already handed to the browser cannot be cancelled by editing the form; stale completion messages are suppressed.
Hosting and future advertising
The hosting provider may process ordinary requests, IP addresses and technical information to deliver and protect the site. Calculator source in this release has no active advertising, analytics or consent-platform script. A public ads.txt file and account metadata prepare possible future advertising; they do not activate ads. This notice must be updated if tracking is enabled.
Links and contact
Following a W3C reference opens an external service governed by its own practices. Email is handled by your email provider and the shared forwarding service. Send only the information needed to describe a correction; do not include passwords or personal records.
