Calculator data
Measurements entered into calculators are processed in the browser and are not intentionally transmitted to Curtain Size Lab or saved to a user account. Printing uses the browser’s print function.
Aggregate analytics
Cloudflare Web Analytics measures aggregate traffic without cookies and is not used by Curtain Size Lab to identify a visitor or follow them across websites. Cloudflare publishes its own current privacy and data-processing terms.
Technical delivery
OpenAI Sites hosts the application and Cloudflare provides domain, security, delivery, and analytics services. Those providers may process ordinary technical request information such as IP address, timestamp, requested page, and user agent to operate and protect their services.
Future changes
Advertising, active affiliate tracking, lead generation, or any nonessential cookie will require a policy update and appropriate user controls before activation.
