The short version: use Cherilov for your own good work, keep your own books safe, only publish books you have the right to share, and don't misuse keys or the trial.
By using Cherilov Flipbook Studio or Cherilov Reader ("Cherilov"), you agree to these terms.
You own the books, pictures, videos and other content you make. You are responsible for having the right to use anything you put into Cherilov, and for not using it to make unlawful or harmful content. Your files stay on your device, so please keep your own copies. We cannot recover them for you. This includes books you publish online: keep the original PDF and design.
Cherilov, including its name and logo, the website, the Studio and Reader, their code and design, and our own pictures, videos, sample books, sticker and background packs and written text, is owned by Cherilov and protected by copyright. Using Cherilov does not give you any ownership of it.
Please do not copy, sell, rent out or rebuild Cherilov or any part of it, try to get at its code or servers in ways we have not offered, scrape it, or use the Cherilov name or logo in a way that suggests you are us or that we endorse you. You may share links to Cherilov and to your own online books, and talk about Cherilov freely.
Plus and Premium renew automatically (every month, or every 6 or 12 months if you chose a longer plan) until you cancel. You can cancel any time from your Gumroad receipt email or your Gumroad account. Your plan then stays on until the end of the period you already paid for, and you will not be charged again. Please cancel before the renewal date if you do not want the next payment.
Refunds follow the refund policy shown on the Gumroad page where you bought. Each product page shows its refund period before you pay. The law where you live may give you extra rights, and those still apply. If something is not working, please email cherilov.studio@gmail.com first and we will do our best to put it right.
The free Premium trial lasts 2 days and is available once per Google account. Pictures and videos made during the trial keep the Free watermark. We may end a trial or refuse one if it looks like someone is working around the one-trial limit.
If you think an online book breaks your copyright or these rules, email cherilov.studio@gmail.com with its link and the details. Readers can also use "Report this book" in the Reader. We will look at it and take the book offline if needed. For books that are not online, we do not store them, so we cannot take them down. We may switch off a license key or free trial that is being used to break the law.
Names such as Google, Gumroad, Canva, GoodNotes and Pinterest belong to their owners. Cherilov is not affiliated with, or endorsed by, any of them.
Cherilov is a small, growing product. Features, plans and prices can change over time. If prices change, we will tell you through Gumroad as its rules require.
We work hard to keep Cherilov useful and reliable, but we provide it "as is", without a guarantee that it will always be available or free of errors. To the extent the law allows, we are not responsible for lost files or indirect losses from using Cherilov, and our responsibility for any claim is limited to the amount you paid us in the 3 months before it.
You are responsible for the books and content you publish and for how you use Cherilov. If someone makes a claim against Cherilov because of your content, or because you broke these terms or the law, you agree to cover the reasonable costs and losses that come from it, to the extent the law allows.
These terms are governed by the laws of the Hong Kong Special Administrative Region, and the Hong Kong courts can hear any dispute about them. If you are a consumer, you keep any rights the law where you live gives you.
If we change these terms, we will update this page and its date. Continuing to use Cherilov means you accept the updated terms.
