We’ve just published two new legal documents to the hosted version of the polyfill service, Polyfill.io. If you’re hosting your own version of the polyfill service, these documents don’t affect you – they only apply to people using a version of the polyfill service that we host.
The terms of service document describes what you can expect from us when you use Polyfill.io on your site, and the actions you, as a user, might take that would cause us to revoke your access to Polyfill.io.
Why have we added these documents?
As for the Terms of Service, Polyfill.io usage has been climbing since we launched it 3 years ago, and is now used by sites around the world. At the FT we both maintain the open source project and host Polyfill.io for free (and Fastly provides free global caching on their CDN). The Terms of Service help ensure we can keep doing this.
What it means for users of Polyfill.io
