Embed terms of use

Free to embed the calculator on any website.
The “Powered by CircuitProof” attribution footer must remain visible on the free tier. Team-tier accounts may remove it via a verified embed key.
No reverse-engineering, scraping, or re-hosting of the calculator logic.
We may revoke any embed that misrepresents calculator output or violates ABYC/NEC guidance.
We record the host domain and anonymized usage counts only — no end-user personal data.
The calculator is a planning aid, not a P.Eng/PE stamp. Verify with a licensed professional and applicable codes before installation.
