Terms of Service

1. Who we are and what this is

Yalla Nihongo ("we", "us") is a Japanese-language learning platform operated from Tunis, Tunisia. The service includes the hiragana curriculum, spaced-repetition reviews, games, culture library and any community features we add later.

By creating an account you accept these terms and our Privacy Policy. If you do not accept them, please do not create an account.

You must be at least 13 years old to hold an account. If you are under 18, you may use the service only with the permission of a parent or legal guardian, who accepts these terms alongside you. We do not knowingly create accounts for children under 13; tell us and we will remove any that exist.

2. Your account

Give us accurate information when you register, and keep it current. Hold one account per person — extra accounts created to game leaderboards or streaks may be removed.

You are responsible for keeping your password safe and for activity that happens under your account. Tell us promptly if you believe someone else has access to it.

We may suspend or close an account that is used to break these terms, to abuse other learners, or to attack the service. Where it is feasible and lawful, we will tell you why.

3. Our content and intellectual property

The lessons, memory images, example sentences we write ourselves, culture cards, folktale retellings, illustrations, the mascot Fenn, the name and the visual identity are the intellectual property of Yalla Nihongo, protected by Tunisian and international copyright law.

We grant you a personal, non-exclusive, non-transferable licence to use this content to learn Japanese, for as long as your account is open.

You may not scrape, bulk-download, resell, sublicense, republish or use our course content to train a commercial model or to build a competing product. Sharing a screenshot with a friend or a classmate is fine; exporting the curriculum is not.

Some of what we use is third-party open data under its own licence, and those licences — not this section — govern it. The Licenses & Attribution page lists every item, its licence and how we comply.

4. Your content

Anything you post — messages, group names, photographs from events, profile text — remains yours. We claim no ownership of it.

You grant us a non-exclusive, worldwide, royalty-free licence to host, store, reproduce and display your content for the purpose of operating and showing the service. This licence exists so we can legally display your post to other learners; it ends when you delete the content or your account, except for copies already made in routine backups, which age out on our normal schedule.

Do not post content you do not have the rights to, content that infringes someone else's copyright or trademark, or content that is unlawful. We act on the complaints procedure described on the Licenses & Attribution page, and accounts that repeatedly infringe lose the ability to post.

5. Community rules

Learners here come from different countries, ages and levels. Treat them the way you would want to be treated on your first day in a language class.

Not allowed: harassment or bullying, hateful content targeting people for who they are, sexual content involving minors, threats, spam and advertising, impersonation, and deliberately sharing wrong answers to sabotage others.

We may remove content or restrict an account that breaks these rules. If you think we got it wrong, reply to the notice we send you and a person will review the decision.

6. What is free, and future paid features

The hiragana curriculum, your daily spaced-repetition reviews and the basic games are free to use, and we commit to keeping them free.

We may introduce optional paid features in future. If we do, prices will be shown in Tunisian dinars (TND) and charged through Tunisian payment gateways.

7. Availability, changes and warranties

We provide the service on a best-effort basis. We may add, change or remove features as the platform develops. We will avoid removing something you depend on without notice where we reasonably can.

The service is provided "as is". To the maximum extent permitted by applicable law we exclude implied warranties, and we are not liable for indirect or consequential loss, lost data beyond our reasonable control, or loss arising from your use of the service.

Nothing in these terms limits liability that cannot be limited by law — including liability for death or personal injury caused by negligence, for fraud, or under any mandatory consumer-protection rule that applies to you.

8. Ending your account

You may delete your account at any time in Settings. Deletion removes your profile and learning data as described in the Privacy Policy. Export your data first if you want to keep it — Settings has a one-click JSON export.

We may suspend or terminate an account for a serious or repeated breach of these terms. Where it is feasible and lawful, we will give you notice and a chance to respond.

9. Governing law

These terms are governed by the law of the Republic of Tunisia, and disputes are subject to the competent courts of Tunis.

If you use the service as a consumer resident elsewhere, this does not remove the protection of any mandatory consumer-protection law of your country of residence, or your right to bring proceedings there where that law allows it.

10. Changes to these terms

These terms are versioned. The version and effective date sit at the top of this page, and previous versions are kept so you can see what changed.

When we make a material change — one that affects your rights or our obligations — we announce it in the app at least 14 days before it takes effect and ask you to accept the new version. Minor corrections take effect when published, with a notice in the app.

Continuing to use the service after a change takes effect means you accept the new version. If you would rather not, you can export your data and delete your account.
