Web trial and iOS purchase questions
View the complete FAQWhat is the difference between the free Web trial and the iOS App?
The free Web trial opens selected reading and interactive content in a browser without payment. Each iOS App book is a separate one-time purchase with no Jiseikou Studio account, no ads, and offline reading support.
Is the iOS App a subscription?
No. The Web trial is free, and each iOS App book is a separate one-time purchase rather than a monthly or annual subscription.
Does purchasing Vehicle Friends include future books?
No. The free Web trial does not make a purchase. Each iOS book is a separate one-time purchase, so buying Vehicle Friends unlocks only this book; future books are sold separately.
When can I purchase the iOS App?
The iOS App release date has not been announced. A verified App Store link will be added to the main site after release. The free Web trial is available now.
Who handles iOS App purchases?
The free Web trial does not require payment. After the iOS App is released, purchases will be handled by the Apple App Store, with no separate Jiseikou Studio payment account required.
How do I request an iOS App refund?
The free Web trial does not create a charge. Apple handles iOS App payments and refunds, so requests must be submitted through Apple’s purchase history and refund process. Jiseikou Studio cannot approve refunds on Apple’s behalf.
