Terms of use
Last updated: November 11, 2026
These terms govern the use of Minarai, an app for learning languages (Japanese for now, with the idea of adding more languages in the future). By using the app you accept these terms; if you don't agree, please stop using it.
Who provides the app
Minarai is an independent app. For any questions about these terms, you can write to contacto@minaraiapp.com.
Using the app
Minarai can be used for free and shows no ads. The free version includes a limited number of study sessions per day; reviews are unlimited.
To use the app you need a Minarai account, which you can create with your email and a password or by signing in with Google. Your progress is saved to your account so you can recover it when you reinstall the app or switch devices.
We ask that you use the app reasonably and do not attempt to interfere with its operation, access parts not intended for the public, or use it for purposes other than personal language learning.
Minarai Premium
Minarai Premium extends the app with additional features, such as studying without the daily session limit, the mistakes review, detailed progress statistics, the hint and memory writing modes and the Sakura, Matcha and Momiji colour styles. We may change the features included in Premium over time.
Premium is a paid subscription available monthly or yearly. The price of each option is shown in the app (Settings → Subscriptions) before you confirm the purchase. You need a Minarai account to subscribe: the subscription is tied to that account.
Payments are processed by Google Play, using the payment method on your Google account, and are also subject to Google Play's terms. We never receive or store your card or payment details.
Free trial: the first time you subscribe you can enjoy 7 days free. If you don't cancel before the trial ends, the subscription starts automatically and you are charged for the plan you chose. The free trial can only be used once.
Renewal and cancellation: the subscription renews automatically at the end of each period (month or year) for the same term and price, unless you cancel it beforehand in Google Play (Settings → Subscriptions → Manage or cancel subscription). If you cancel, you keep Premium until the end of the period you've already paid for and you won't be charged again. Uninstalling the app or deleting your account does not cancel the subscription in Google Play.
Price changes: if we change the price of Premium, you will be notified in advance through Google Play and can cancel before the new price applies.
Refunds: since charges are made by Google Play, refunds are requested from Google under its policies. This does not affect any rights you have under applicable consumer law. If you have any problem with your subscription, write to us at contacto@minaraiapp.com.
User accounts
You are responsible for keeping your password confidential and for any activity on your account. You can delete your account at any time from Settings → Edit profile → Delete account.
To create an account, and therefore to use the app, you must be at least 14 years old or, if you are younger, have the consent of your parent or legal guardian.
Your progress
Your study progress (stamps, completed chapters, streak and review statistics) is stored on your device. A copy is also saved to the cloud, linked to your account, so you can recover it after reinstalling the app or when signing in on another device.
Although we take every care, we don't guarantee that this data will be kept indefinitely.
Intellectual property
The text, illustrations, design and other content of Minarai belong to their authors or are used under license. Stroke order data comes from KanjiVG (CC BY-SA 3.0 license). You may use the app for your personal learning, but you may not copy, redistribute or commercially exploit its content without permission.
No warranties
Minarai is provided "as is". We take care to make sure the content is accurate and the app works well, but we cannot guarantee that it will always be free of errors, interruptions or technical failures.
Limitation of liability
To the extent permitted by law, we will not be liable for indirect losses or damages arising from your use of the app, including the loss of progress stored only on your device.
Changes to the app and these terms
We may update the app or these terms over time. When a new version of the app is available on Google Play, we may let you know within the app; updating is up to you, although some features may require the latest version. If a change to these terms is significant, we will update the date shown above and, when we consider it necessary, let you know within the app or, if you have turned them on, through email or push updates.
Termination
You may stop using the app at any time by uninstalling it and, if you have an account, deleting it. If you seriously breach these terms, we may limit or suspend access to features that require an account or to Premium.
