利用規約 Terms of Service

These terms govern your use of ミステリー日本語. By using the app you agree to them.

The service

A Japanese-learning app. Everything in it is free: every lesson of every level, かな, 辞書, 書き取り, 復習 and every mock paper. The full version, bought once, removes the ads in the Android and iPhone apps and adds nothing else. We may add, revise or reorganize lessons as the course grows.

The full version

• US$9.99, paid once when you buy it. In the Android app, Google Play shows the price in your currency, and in the iPhone app, the App Store does.
• It removes the ads and adds nothing else: every lesson is free. Bought on the web or in the Android app, it holds on every device where you sign in; bought in the iPhone app, it holds on that iPhone and, through Restore purchase, on any other signed in to the same Apple Account. It does not expire and nothing renews. Bought in the Android app, it is also subject to Google Play's terms; bought in the iPhone app, to Apple's.

Refunds

• In the app, under 設定, you can refund the full version in full within 7 days of buying it, once per account, whether you bought on the web or in the Android app. It ends at once, and the money goes back to the original payment method.
• Bought in the iPhone app, it is charged by Apple, and its refunds go through Apple.
• Buying on the web from the EU, the EEA or the UK, you ask at checkout for the full version to unlock at once and agree that you lose your 14-day right to cancel once it unlocks; we confirm this by email. The 7-day refund above still applies.
• Beyond that, we refund a charge made twice and a purchase a fault on our side kept from working: write to support@latticelogic.app with the charge date.
• A Google Play purchase is refunded through Google Play's own process.
• Nothing here limits your statutory rights.

Disclaimers and liability

The app is provided as-is. To the extent the law allows, our total liability for any claim is limited to the amount you paid us in the twelve months before the claim arose. Nothing here limits liability that cannot be limited under applicable law.

Disputes

These terms are governed by the law of Singapore, and disputes go to the courts of Singapore. Claims are brought individually, not as part of a class action.
