Terms of service

These terms

These terms are a binding agreement between you and Naraio ("we", "us") for the use of naraio.app and everything it offers ("the service"). By creating an account or using the service you accept them. If you do not agree, do not use the service. The privacy policy is part of this agreement.

Your account

• You must be at least 13 years old. If you are under the age of majority where you live, a parent or guardian must agree to these terms for you.
• Give us accurate information and keep it up to date. Keep your password to yourself: everything that happens under your account is your responsibility, and you must tell us at once if you think someone else has used it.
• One account per person. Accounts cannot be transferred, shared or sold.
• We may ask you to verify your email address or identity to protect your account or the service.

The service

Naraio is an app for learning Japanese: writing graded stroke by stroke, dialogues with recorded voices, speaking practice with a tutor, and a path from kana to N1. We are still building it: features arrive over time, change, and are sometimes retired, and the landing page marks what exists and what is coming.

Our levels follow the JLPT so that your progress means something outside the app. We are not affiliated with the JLPT or its organisers, no level we assign is a certification, and we do not promise that you will pass any exam, reach any level or learn at any particular speed. The content is provided for general educational purposes and may contain errors.

Free and paid plans

The Free plan costs nothing and stays free. It has daily limits on some features, stated on the pricing page.

Paid plans are billed monthly or yearly at the prices shown when you subscribe. Payments are handled by our payment provider, which acts as the merchant of record: it charges you, issues the receipt, collects any applicable tax and keeps your payment details. Its terms apply to the payment itself.

• A plan renews at the end of each period until you cancel.
• You can cancel at any time from your account. You keep the plan until the end of the period you paid for. We do not refund the remainder of a period, except where the law where you live requires it or where we made a mistake. If a charge looks wrong, write to us within 14 days and we will look into it.
• If we change a price, we tell you at least 30 days before it applies to your next renewal.
• If a payment fails and is not resolved within a reasonable time, we may downgrade the account to the Free plan.
• Trials, discounts and promotions are subject to the conditions stated when they are offered.
• Classroom plans are agreed in writing with the school; those terms add to these.

Credits and limits

Free conversation with the tutor is measured in credits: one credit is one minute. Plans include a number of credits a month and you can buy more. Credits have no cash value, cannot be transferred or exchanged, are not refunded when a plan ends, and may expire as stated when they are granted. Daily limits on the Free plan reset every day. We may adjust limits and credit amounts with notice, to keep the service sustainable; attempts to get around them are a breach of these terms.

Your content

What you write, the strokes you draw, what you say to the tutor and any dialogue you create belong to you. You give us a worldwide, non-exclusive, royalty-free licence to store, process, reproduce and display that content as needed to run the service for you: grade your strokes, score your speech, keep your history, generate the audio you asked for, and improve the service using anonymous, aggregated information (for example, how many people got a stroke wrong). We do not use your content to train AI models of our own. You are responsible for the content you submit and confirm that you have the right to submit it. We may remove content that breaks these terms.

Our content and your licence

The service, including its lessons, dialogues, recordings, explanations, design, software, name and logo, belongs to us or to our licensors and is protected by intellectual property law. We give you a limited, personal, non-exclusive, non-transferable, revocable licence to use it for your own learning. You may not copy, scrape, download in bulk, resell, redistribute, publicly perform or build another product from it, remove any notice from it, or use our name or logo without written permission.

Some reference data on the site comes from openly licensed sources; their credits appear on the site and their licences apply to that data.

AI features

The tutor's replies, the katakana spelling of your name and other generated content are produced by artificial intelligence. They are usually right and sometimes wrong, incomplete or unsuitable. Check anything that matters, treat the tutor as practice rather than as the final word on grammar, and do not rely on generated content as professional advice of any kind. Do not share sensitive personal information in conversations. You are responsible for how you use what the service generates.

Acceptable use

You agree not to:

• Break into the service, probe or test its security without our written permission, or interfere with how it works.
• Access it by automated means beyond normal use of the app: scraping, bulk downloads, bots or crawlers.
• Get around limits, share an account, or use Classroom seats for people who are not your students.
• Submit illegal, abusive, hateful, infringing or harmful content, or use the service to harass or harm anyone.
• Reverse engineer, decompile or copy the service, or present it as your own.
• Use the service in a way that breaks any applicable law.

We may investigate suspected breaches and take any action we consider appropriate, including removing content, suspending or closing accounts and informing the authorities.

Changes, availability and support

We improve, change and sometimes retire features, and we may suspend or discontinue all or part of the service. If a change takes away something a paid plan includes, we tell you before it happens. We aim to keep the service up and run maintenance when needed, but we do not promise that it will be available at any particular time, without interruption or without errors. Support is provided by email, on a reasonable-effort basis.

Third-party services

Parts of the service rely on third parties, such as the provider you sign in with or the one that processes your payment. Their terms govern your relationship with them, and we are not responsible for their services, their availability or their content.

Suspension and termination

You can close your account whenever you like by writing to us; your data is then removed as the privacy policy describes. We may suspend or close an account that breaks these terms, that creates risk or legal exposure for us or for others, or where the law requires it, with notice when we can give it. We may also close accounts that have been inactive for a long time, after telling you. When an account ends, your licence to use the service ends with it; no refund is owed if the account was closed for a breach. If we close the service as a whole, we give paid users at least 30 days' notice and refund what remains of their period. The sections on your content, our content, disclaimers, liability, your responsibility, governing law and general terms survive the end of this agreement.

No warranties

The service is provided as it is and as it is available. To the fullest extent the law allows, we make no promises about it: not that it will be accurate, complete, reliable, uninterrupted, secure or free of errors, nor that it will meet your needs or produce any result. Any warranty that the law would otherwise imply is excluded to the extent permitted.

Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive losses, nor for lost profits, lost data, lost opportunities or the cost of substitute services, however they arise. Our total liability to you for everything connected with the service is limited to the amount you paid us in the twelve months before the event giving rise to the claim. Nothing in these terms limits a liability that cannot be limited by law, or rights that consumer law gives you and that cannot be waived.

Your responsibility

If someone makes a claim against us because of your content, your use of the service or your breach of these terms or of the law, you will cover the losses, costs and reasonable legal fees that claim causes us, as far as the law where you live allows.

Governing law and disputes

These terms are governed by the laws of the place where Naraio is established, without regard to its conflict-of-law rules. If something goes wrong, write to us first; most issues are settled in an email. A dispute that cannot be settled that way will be brought before the courts of the place where Naraio is established, unless mandatory consumer law where you live gives you the right to another venue.

General

• These terms and the privacy policy are the whole agreement between you and us about the service and replace any earlier one.
• If a part of these terms turns out to be invalid, the rest stays in force.
• If we do not enforce a term at some point, we may still enforce it later.
• You may not transfer this agreement to anyone else. We may transfer it as part of a sale, merger or reorganisation of Naraio.
• We are not responsible for a failure or delay caused by events outside our reasonable control.
• We may send notices to the email address of your account; you can write to us at [email protected].
• These terms exist in several languages. If the versions differ, the English version applies as far as the law allows.

Changes to these terms

We may update these terms. For anything significant we tell you by email or in the app at least 14 days before it applies; using Naraio after that date means you accept the new version. The date at the top is the date of the current one.
