Terms of use. Free for non-commercial and commercial use. Don't strip the "Powered by Fortis Shield" link or modify the iframe contents. The widgets fetch live data from our public supplier database — they always show current prices and Fortis Scores.

FAQ

Are these widgets free forever?

Yes, free as long as you keep the "Powered by Fortis Shield" link visible and don't modify the iframe content. We don't track your readers (only generic impression / interaction events from the iframe itself).

How do they stay current?

The widgets fetch live data from /suppliers.json on every load. When we add suppliers or update prices, your widget updates automatically — no action needed on your side.

Can I customise the styling?

Not at the moment. We keep widget styling consistent so readers recognise the Fortis Shield brand across the web. If you have a strong styling need, email partnerships@fortisshield.net — we can discuss white-label options.

Will the widgets slow my page?

Iframes load asynchronously with loading="lazy", so they don't block your main page render. The total widget weight (HTML + dynamic supplier data) is under 25KB.

Can I use them on commercial / monetised sites?

Yes — including ad-supported, subscription, and affiliate sites. We don't restrict commercial use as long as the Powered-by link remains visible.
