The calculators run in your browser. They do not ask you to upload an image or create an account, and the site does not currently send advertising requests.

Basic delivery and audience measurement

Cloudflare may process ordinary request information needed to deliver and protect the site, such as an IP address, requested URL, browser information and time of access. We also use Cloudflare Web Analytics to measure aggregate page loads and visits so we can improve useful pages. The site does not use this measurement to identify visitors or attribute a visit to search when no search-engine referrer is present.

Cookies and advertising

Advertising code is prepared but locked behind four required settings: an approved publisher ID, a valid ad unit, a ready consent-management setup and an explicit enable switch. Until all four are present, the site does not load the AdSense script or create ad requests.
