Terms of use

The service

Riffle converts PDF documents into interactive flipbook files, entirely in your browser. The free tier builds the first 3 pages of any document with a small badge. A license builds the whole document badge-free: licenses are one-time purchases delivered as signed keys by email, verified on your device, recoverable at /recover, and never a subscription. Anything you build stays yours and keeps working.

Your content

You keep all rights to the documents you convert and the flipbooks Riffle builds from them. Because conversion happens on your device, we never receive, host, or moderate your content. You are responsible for having the rights to the documents you convert and for how you share the results.

Acceptable use

Do not use Riffle to produce or distribute unlawful content, and do not misrepresent a Riffle-built file as software it is not. That is the whole list.

No warranty

Riffle is provided as is, without warranty of any kind. We work to make conversion faithful and files durable, but we cannot guarantee fitness for a particular purpose. Keep your original PDFs; a lost flipbook password cannot be recovered by anyone, including us.

Liability

To the maximum extent permitted by law, Riffle is not liable for indirect or consequential damages arising from the use of the service. Our total liability is limited to the amount you paid us in the twelve months before a claim.

Changes

We may update these terms; the effective date above changes when we do. Continued use after a change means acceptance. Files already built are never affected retroactively.
