Legal Notice (Japan): Act on Specified Commercial Transactions
Last updated: November 8, 2026
This is an English translation of the Japanese original, with additional information for users in the EU, the EEA and the UK. If the two versions differ, the Japanese version prevails, except that this never limits any rights you have under the mandatory consumer-protection or data-protection laws of the country where you live.
This page contains the disclosures that Japan's Act on Specified Commercial Transactions requires for the paid plan of Riffle. It also serves as our provider information.

- Price
- Free plan: $0. Pro plan: the amount shown on the checkout screen. The currency and amount you pay are shown on the checkout screen.
- Costs other than the price
- Communication charges needed to connect to the internet are your responsibility.
- Payment methods
- The methods shown on the checkout screen (Stripe), such as credit card. The free plan involves no payment.
- Payment timing
- For the Pro plan, you pay the first fee when you subscribe. After that, the plan renews automatically each billing period (shown on the checkout screen), and the fee is charged on the renewal date.
- When the service is provided
- The free plan is available from the moment you sign in with a Google account. The Pro plan is available immediately after payment is confirmed.
- Returns and cancellation
- Because this is a digital service, we do not accept returns or refunds after the service has been provided, except where the law gives you the right to a refund (see the notice for consumers in the EU, the EEA and the UK below). You can cancel the Pro plan at any time from "Manage subscription" on the Pricing page. After cancelling, you can keep using the Pro plan until the end of the billing period you have already paid for, and you will not be charged from the next renewal. Cancelling partway through a billing period does not entitle you to a pro-rated refund. You can delete your account for the free service at any time from the settings screen. If you delete your account while you have a paid plan, the subscription is cancelled as part of the deletion procedure.
- Notice for consumers in the EU, the EEA and the UK
- If you are a consumer who lives in the EU, the EEA or the UK, you have the right to withdraw from a Pro plan subscription within 14 days of subscribing, without giving a reason. To withdraw, send a clear statement to contact@riffle.page within that period. Because the Pro plan starts immediately when you subscribe, you pay a proportionate amount for the period until you withdraw, and we refund the rest. If the Pro plan has been fully provided, the right of withdrawal ends. See Article 9 of the Terms of Service.
- What happens after the subscription ends
- If a Pro plan subscription ends and you return to the free plan, books older than the storage period (30 days) become unreadable, and are permanently deleted 7 days after the day you returned to the free plan (this cannot be undone). If you return to the Pro plan before deletion, you can read them again. See the Terms of Service for details.
- System requirements
- A current version of a web browser with JavaScript enabled, such as Chrome, Safari, Firefox or Edge. Mobile browsers are supported.
