Terms of use

Draft. This page has not yet had a final legal review and may change before HitaruJP launches in the app stores.

These terms apply when you use the HitaruJP app on Android, iOS or the web, and the website at hitarujp.app. By creating an account, you agree to them.

Your account

• You need to be at least 13 years old to use HitaruJP.
• Keep your sign-in details safe. You’re responsible for what happens on your account.
• Give accurate information when you sign up.

Using HitaruJP

Please don’t:

• try to break, overload or get around the security of the service;
• scrape, copy or resell the catalogue or the AI explanations at scale;
• use HitaruJP to break the law or anyone else’s rights;
• misuse the AI features, for example to generate harmful content.

We may suspend accounts that do these things.

Videos and other content

The videos in HitaruJP belong to their creators on YouTube and are played through YouTube’s own player, under YouTube’s Terms of Service. We choose and tag videos, but we don’t own them. If you’re a creator and want a video removed, contact us and we’ll take it out.

The HitaruJP app, its design, characters, text and code belong to HitaruJP.

What you create (your vocabulary lists, flashcards and notes) stays yours. You give us permission to store and process it only to run the service for you.

AI explanations

AI explanations are generated by a language model and can be wrong. Use them as a learning aid, not as an authority. Don’t rely on them for anything important, such as legal, medical or official translations.

Free and paid plans

HitaruJP is free while in beta. If we introduce a paid plan, we’ll publish its price and what it includes before you’re asked to pay, and these terms will be updated with subscription and refund details. Purchases through the App Store or Google Play also follow their terms.

Availability

We work to keep HitaruJP running, but we can’t promise it will always be available or free of errors. We may change or remove features. If we ever shut HitaruJP down, we’ll give you notice and a way to export your data.

Liability

HitaruJP is provided “as is”. To the extent the law allows, we aren’t liable for indirect losses, or for losses caused by content made by others (including YouTube videos). Nothing in these terms limits rights you have under consumer law that can’t be excluded.

Ending your account

You can stop using HitaruJP and ask us to delete your account at any time (see the privacy policy). We may close accounts that break these terms.

Changes

If we change these terms in a way that matters, we’ll update the date at the top and tell you in the app before the change applies.
