Terms of use

Effective August 2, 2026

The service

Riffle converts PDF documents into interactive flipbook files, entirely in your browser. Riffle is currently in free early access: features may change, and paid plans will be introduced later. Anything you build during early access 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, Mocklet Design is not liable for indirect or consequential damages arising from the use of Riffle. Our total liability is limited to the amount you paid us in the twelve months before a claim, which during early access is zero.

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.
