Inquiry about platform switching

YOUR DECKS · YOUR LEARNING

Purchased decks are recognized for purchase even if the platform changes.

Decks purchased for a fee on Quiz Notebookare recognized as having the right to use the deck regardless of the purchase platform. The operating principle is to support users who do not repurchase the same deck even when moving from app to web app or from web app to app.

Purchase rights for the app used for learning or a valid web app usage pass are required separately. Refunded or canceled products and other people's purchase rights are not included; deck-specific usage conditions and the applicable store policies apply.

Current connection status · Preparing for automatic integration

Store purchase history and web app account are not automatically linked. Even if the purchase email is the same, it does not open immediately. Before paying for the license to switch platforms, Please provide the name of the deck you purchased, the place of purchase, order number, and the platform you will use. We will check your purchase history and available connection routes to guide you. We do not guarantee that products without connectivity features will be available immediately.

I also keep my deck that I commissioned to craft.

Even after the web usage period included in the production rights ends, the rights to hold and use the completed deck already delivered will not be lost. You can keep the file and import it to a compatible paid app, or purchase a web license to continue studying. The copyright and scope of use of the original materials remain in effect.

Frequently Asked Questions

If I buy directly, do I have to pay again in the store?

External purchases do not automatically convert to store purchase rights. In particular, paid download apps may require payment during the installation stage before logging in with our account. Before starting direct sales, we will prepare the official system that allows installation and activation without re-payment. Do not make duplicate purchases expecting linkage that is not currently available.

If I enable Family Sharing, can I use the deck I bought together?

It varies by product. In-app purchases on Google Play are not part of the Family Library, and Apple requires Family Sharing settings for those products. Currently, Quiz Notebook's three licensed agent decks have iOS Family Share turned off.

If I install it on multiple devices, will the learning materials automatically be merged?

Installation and usage rights and data transfer are separate. You must use backup/restore or the sync feature provided by the app. Family data is not automatically merged or made public.

If I buy it once, will all future products be free?

A one-time purchase is a usage pass for the purchased product. This does not mean that a separate platform version, paid learning decks, or new products are all included. Please check the provided features and update conditions based on the sales notice for each product.
