Calculator inputs
Pixel dimensions, physical dimensions, and PPI/DPI values are used in your browser to calculate the result. The application does not send these values to an application server in the current version.
Images you select
When you choose an image, the browser decodes it to read its pixel width and height. The current application does not upload the image to an application server or retain it after you leave or reload the page.
Usage analytics
Cloudflare Web Analytics measures aggregate page visits, referring hostnames, device and browser categories, countries, and page performance. The site does not use this service to set an application analytics cookie, store an analytics identifier in local storage, or build an individual visitor profile.
The calculator also sends four limited product events to a first-party Cloudflare Pages Function: a successful calculation, a conversion-direction change, a successful result copy, or a successful local image-dimension read. These events include only the event name, page path, conversion direction, and a referring hostname such as google.com, direct, or internal. They do not include calculator values, image dimensions, file names, image contents, full referring URLs, query strings, user IDs, or advertising IDs.
Events also include a non-identifying traffic label: explicitly marked QA tests or unclassified traffic. The label does not identify a visitor or prove a visit is human. Product-event aggregates are stored in Cloudflare Workers Analytics Engine for up to three months. They are used to understand whether the calculators are useful and which public pages lead to successful tool use.
When a tester explicitly opens a calculator with analytics_test=1, a single QA flag is kept in that tab's session storage so later calculator actions remain marked as tests. It contains no identifier or input values. Opening a calculator with analytics_test=0 clears the flag; closing the tab normally ends that session. This flag labels product events only and does not exclude visits from Cloudflare Web Analytics.
Accounts, payments, and advertising
The current version does not provide accounts, payments, or advertising. If those services are introduced, this notice and any required consent controls must be updated before they are activated.
Hosting logs
The site is delivered through Cloudflare. Cloudflare may process standard request information such as IP address, browser type, requested URL, and timestamps to provide delivery, reliability, abuse prevention, and security services. Cloudflare handles that information under its own privacy commitments.
Your choices
You can use the calculator without selecting an image. You can remove a selected image from the current page using the Clear control or by closing the page. Browser privacy tools or network controls may block analytics requests without preventing the calculator from working.
