PROFENG calculator embed terms

Eligible calculator embeds are provided so engineering teams, educators and technical sites can make a PROFENG calculation interface available inside an iframe.

Required attribution

The visible Powered by PROFENG link and link to the canonical calculator must remain visible and unmodified.

No output interference

The host must not alter, obscure or replace calculator inputs, outputs, source status, limitations, verification wording or correction links.

Tracking

The PROFENG embed view does not load PROFENG GA4, Vercel Analytics, Speed Insights or advertising scripts. Normal web-server/security logs can still exist at the hosting layer.

No certification

Embedding a calculator does not turn its result into a certified or stamped engineering document and does not imply PROFENG approval of the host site.

Canonical source

The full calculator page remains the canonical location for formula notes, source acknowledgements, assumptions, limits and corrections.
