Terms

Effective 30 September 2026.

The agreement

These terms are between you and Converra, Inc., a Delaware corporation ("Converra", "we"), which runs Cinder. They cover the Cinder iPhone app and the website. By using either, you agree to them and to our Privacy policy. If you don't agree, don't use Cinder.

An early, invite-only service

Cinder is in an early, invite-only stage and is offered in the United States. Features may change, stop working, or be removed, and the service may be unavailable at times. We may limit how many pictures you can make. There is no charge while Cinder is invite-only; we'll tell you before anything costs money.

Your account

You need an invite and an email address you control. You must be at least 13. If you're under 18, you need a parent or guardian's permission to use Cinder. Keep access to your email secure, since anyone who can read it can sign in as you. You can delete your account at any time in the app.

How pictures are made

Cinder uses AI to make pictures from details about the book you choose. The pictures are interpretations. They may be inaccurate, may not match the book, and may show things the book doesn't describe. Pictures for a whole book show its world and characters, not a particular event. Cinder may reveal details of a book you haven't reached yet.

Cinder is not affiliated with, or endorsed by, the authors, narrators or publishers of the books you choose, or by the app you listen with.

What you add

You're responsible for the text you add, such as a page you type or photograph. Only add text you have the right to use for your own personal reading, and don't add anything unlawful or anything that identifies another private person. You let us use what you add only to make and show your pictures.

Using your pictures

As between you and Converra, the pictures Cinder makes belong to Converra, including pictures made for books you choose. We let you keep, view and share the pictures made for you for personal, non-commercial purposes. Pictures can resemble characters and settings from books that others own, so we can't give you rights to use them commercially, and you're responsible for how you use them outside Cinder.

We may store, show and use pictures to run and improve Cinder, including to train or tune AI models, as the Privacy policy explains. Pictures of a book's world, and of chapters Cinder found published information about, may also be shown to other listeners of the same book, as the Privacy policy explains. Shared chapter pictures are also published on public pages at cindergo.com/books, where anyone, including search engines, can see them, as the Privacy policy explains.

The Cinder app, website, name and design belong to Converra. We give you a personal, non-transferable right to use them under these terms.

Requesting permission to use a picture

For questions about using a picture on this website, email support@cindergo.com with the picture's page address and how you want to use it. The personal, non-commercial permission above applies to pictures made for you; appearing on this website does not grant other visitors permission to reuse a picture. Contacting us does not grant permission, and we cannot grant rights belonging to a book's author, publisher or other third parties.

Rules

Don't use Cinder to:

We may suspend or close an account that breaks these rules.

Reporting a picture or a copyright concern

If a picture is offensive or harmful, use Report on the picture in the app. You can also email support@cindergo.com with the book and chapter. If you believe something in Cinder infringes your copyright, email us with what it is, where it appears, and how to reach you, and we'll look into it and remove it where appropriate.

Ending

You can stop using Cinder and delete your account at any time. We may end or suspend the service, or your access, with notice where we reasonably can. The Privacy policy explains what happens to your data.

Warranty and liability

CINDER IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. WE DON'T PROMISE THAT CINDER WILL BE UNINTERRUPTED, ERROR-FREE OR SECURE, OR THAT PICTURES WILL BE ACCURATE OR SUITABLE.

TO THE FULLEST EXTENT THE LAW ALLOWS, CONVERRA WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST DATA, PROFITS OR GOODWILL, ARISING FROM YOUR USE OF CINDER. OUR TOTAL LIABILITY FOR ANY CLAIM ABOUT CINDER IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US FOR CINDER IN THE 12 MONTHS BEFORE THE CLAIM, OR US$50.

Some places don't allow these exclusions or limits, so they apply to you only as far as your local law permits. Nothing in these terms limits rights you have under law that can't be waived.

You agree to cover Converra's reasonable costs from claims by others that arise from your breaking these terms or the law, such as text you added without the right to use it.

Governing law and disputes

These terms are governed by the laws of the State of Delaware, without regard to its conflict-of-law rules. Any dispute will be decided in the state or federal courts located in Delaware, and you and Converra agree to their jurisdiction. Before bringing a claim, please email us so we can try to resolve it.

If you got Cinder from the App Store

General

If part of these terms can't be enforced, the rest still applies. If we don't enforce a part, we haven't given up the right to later. You can't transfer these terms; we may transfer them with Cinder, for example if Cinder is sold. These terms and the Privacy policy are the whole agreement between you and Converra about Cinder.

Changes

We may update these terms. We'll change the date above, and for significant changes we'll tell you in the app or by email before they take effect. If you keep using Cinder after that, you accept the new terms.
