Notes for publishers

Embeds are responsive — set the iframe width="100%" and keep the suggested height (700px for calculators, 900px for quizzes and guides).
The slim “OmniCalcX” attribution bar at the top of each embed links back to the tool — please keep it. Everything else on the page is hidden inside embeds.
If your site uses a Content-Security-Policy, allow frame-src https://omnicalcx.com.
Tools run client-side in the browser; no data is sent to a server, so embeds work on static sites too.
