Fillorin

Terms of Service

Last Updated: October 25, 2026

Please read these terms carefully. They apply to the Learn Japanese app on iOS and Android (the "App"), provided by Fillorin ("we", "us"). By downloading, accessing, or using the App, you agree to these Terms of Service and our Privacy Policy. If you do not agree, please do not use the App.

1. Licence to Use

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control, for your own personal, non-commercial language learning. You may not resell, sublicense, or commercially exploit the App or its content.

2. Your Account

• An account is used to sync your progress across devices and to take part in community features.
• You are responsible for keeping your sign-in credentials secure.
• You agree to provide accurate information and to use only your own account.
• You can delete your account and synced data at any time in the App (Profile → Danger zone → Delete Account) or from our Data Deletion page.

3. Subscriptions and In-App Purchases

The App is free to use and shows advertising. All lessons and stories are free. Learn Japanese Pro is an optional auto-renewing subscription that removes ads.

• Plans and price: Pro is offered as monthly and annual plans. The price, in your local currency, is shown in the App and by the App Store or Google Play before you confirm a purchase.
• Payment: Payment is charged to your Apple ID or Google Play account when you confirm the purchase. We never receive or store your card details.
• Auto-renewal: Your subscription renews automatically for the same period and price unless you cancel it at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the current period ends.
• Managing and cancelling: You can manage or cancel at any time in your store account settings — on iPhone or iPad in Settings → your name → Subscriptions, and on Android in Google Play → Payments & subscriptions → Subscriptions. Cancelling stops future renewals; you keep Pro until the end of the period you have paid for. Deleting the App or your account does not cancel a subscription.
• Free trials: If a free trial is offered, it converts to a paid subscription at its end unless cancelled at least 24 hours before. Any unused part of a trial is forfeited when you buy a subscription.
• Refunds: Purchases are processed by Apple or Google, and refunds are handled under their policies. For App Store purchases, request a refund from Apple at reportaproblem.apple.com; for Google Play purchases, see Google Play's refund policy or contact us.
• Price changes: If the price of a subscription changes, you will be notified in advance as required by the App Store or Google Play, and you can cancel before the new price applies.
• Restoring purchases: Pro is tied to your store account. Signing in with the same store account and choosing Restore Purchases in the App restores an active subscription on a new device.
• Changes to Pro: We may add, change, or remove features and content over time. We will not remove the core benefits of an active subscription during a period you have already paid for.

4. Community Features

Friends, leaderboards, races, and contests let you learn alongside other people. When you use them:

• Your public name, avatar, level, experience points, and contest results can be seen by other users.
• Choose a public name that is not offensive, misleading, or someone else's identity. We may change or remove a name that breaks these rules.
• Play fair: do not use bots, scripts, multiple accounts, or other tricks to gain an advantage. We may remove results, rankings, or access for unfair play.
• Treat other learners with respect. You can report a problem to us at any time.

5. Acceptable Use

When using the App, you agree not to:

• Reverse engineer, decompile, or attempt to extract the App's source code or bundled data, except where the law allows it.
• Copy, scrape, or redistribute the App's content except as permitted by the underlying open licences.
• Interfere with, disrupt, or attempt to gain unauthorised access to our systems or other users' accounts.
• Use the App for any unlawful purpose or in violation of these Terms.

6. Educational Content

The App includes Japanese-language reference material from openly licensed sources (such as JMdict/KANJIDIC, KanjiVG, and Tatoeba), each used under its own licence and credited in the App and in our Privacy Policy. Stories, lessons, and other original material are written by us. All content is provided for study, may contain errors, and is not a substitute for formal instruction. Learn Japanese is an independent tool and is not affiliated with or endorsed by the Japan Foundation, JEES, or the JLPT.

7. Intellectual Property

The App, its design, branding, and original content are owned by Fillorin and protected by applicable laws. Third-party content remains the property of its respective owners and is governed by its own licence terms. These Terms do not grant you any rights to our trademarks or branding.

8. App Stores

These Terms are between you and Fillorin only, not Apple or Google. Fillorin, not Apple or Google, is solely responsible for the App and its content, for providing any maintenance and support, and for handling any claims relating to the App, including product-liability claims, claims that the App fails to meet legal or regulatory requirements, consumer-protection claims, and claims that the App infringes someone else's intellectual property.

If the App fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) of the App to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, may enforce them against you. Your use of the App must also comply with the terms of the store you downloaded it from.

9. Disclaimer of Warranties

To the extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose and accuracy of content. We do not guarantee that the App will be uninterrupted or error-free, or that your data will always be available.

10. Limitation of Liability

To the maximum extent permitted by law, Fillorin shall not be liable for any indirect, incidental, or consequential damages, or for any loss of data or progress, arising from your use of or inability to use the App. Nothing in these Terms limits rights you have under consumer-protection laws that cannot be excluded.

11. Termination

You may stop using the App at any time and delete your account from within the App. We may suspend or terminate access if these Terms are violated. Sections that by their nature should survive termination (such as intellectual property, disclaimers, and limitation of liability) will continue to apply.

12. Changes to These Terms

We may update these Terms from time to time. Material changes will be reflected here with an updated date, and your continued use of the App after changes take effect constitutes acceptance of the revised Terms.
