Terms of Service

1. The Service

Tuned is a language-learning service built around world news. It offers news summaries and audio, lessons by level, a word book, AI conversations and ways to connect with other learners.

The Service has free features and features available on paid plans (such as Plus and Pro). Plan details, prices and free-trial terms are listed on the Plan page and the Legal notice.

2. Your account

You sign in with a Google account or your email address and are responsible for keeping your account secure. If you are a minor, please use the Service with your parent's or guardian's consent.

3. News and AI-generated content

Summaries, translations, lessons, AI replies and grading are generated automatically by AI and may contain errors. Please check the original article from the publisher for accurate information.

Headlines and original articles belong to their publishers. We write our own summaries from the headlines and descriptions publishers make public, and link to the original articles.

AI features have daily usage limits.

4. Paid plans

Paid plan features and prices (tax included) are shown on the Plan page. Seller details are listed in the Legal notice (Specified Commercial Transactions Act).

You pay when you subscribe, by card through Stripe. Monthly plans then renew automatically every month and annual plans every year, on the same day you subscribed, and you are charged at each renewal.

You can cancel anytime from Settings. After cancelling, you keep paid features until the end of the period you paid for, and you won't be charged again.

Payments are non-refundable except where required by law, including no prorated refunds for mid-period cancellations. If the Service is unavailable for a long time due to our fault, we will handle it case by case.

If a free trial is offered and you don't cancel during the trial, your paid plan starts automatically at the end of the trial and you are charged.

If prices change, we will announce it in the Service in advance. New prices apply from your next renewal after the announcement.

If payment fails, we may suspend paid features.

Perks and eligibility for the early-access campaign (Founding Members) and other offers are described on the Plan page. Campaigns may end without notice.

5. Family plan and the kids app

A subscriber to the Family plan (the "Parent") gets Plus and can let up to two children use "Tuned Kids", our English app for children (the "Kids App").

Children's profiles in the Kids App are created and managed by the Parent. Children have no email address and open the Kids App from the Parent's Family page. The Parent is responsible for supervising the child's use under these Terms, and use by the child is treated as use by the Parent.

The Kids App has no messaging or other free-text exchange between children. Children become friends only when both Parents approve on their Family pages, and friends see only each other's nickname, pet, collection and streak.

AI features in the Kids App (conversation, lesson creation, text-to-speech, speech recognition, chess coach, etc.) have daily limits per child.

Prices, free trial, cancellation and refunds for the Family plan follow "Paid plans" above. After cancellation, the Kids App stops working at the end of the paid period. A child's learning records are kept until the Parent deletes the child's profile on the Family page.

The Parent can sign out every device using the Kids App from the Family page.

The Parent can add one more parent or guardian (such as a partner) who has a Tuned account, using an invite code. They can follow the children's progress and open the Kids App, but do not get Plus and cannot manage billing or add or remove children. The Parent can remove them at any time.

6. Your posts

You own what you post. You grant us a free license to display and distribute your posts within the Service (including showing them to other users and creating share images).

Posts are checked automatically before they appear, and posts judged to be abusive may not be published.

7. Prohibited conduct

You must not:

• Break the law or act against public order and morals
• Defame, discriminate against, threaten or harass others
• Post other people's personal information (such as addresses or phone numbers)
• Post spam, advertising or solicitations
• Post sexual or violent content
• Impersonate others or infringe their rights
• Interfere with the Service (unauthorized access, automated mass access, circumventing usage limits, etc.)
• Copy, republish or redistribute the Service's content without permission

8. Suspension

If you break these Terms, we may remove posts, limit features or suspend your account without prior notice.

9. Changes to the Service

We may change, suspend or end the Service without prior notice. It may be temporarily unavailable due to maintenance, outages or problems with third-party services.

10. Disclaimer

We do not guarantee the accuracy, completeness or usefulness of the Service, including AI-generated content. Except in cases of our intentional misconduct or gross negligence, we are not liable for damages arising from your use of the Service.

Disputes between users are to be resolved between those users.

11. Team plan

The Team plan is offered to companies and organizations (the "Customer"). It costs ¥1,980 per seat per month (tax included), with a minimum of 5 seats, or ¥1,480 per seat for 30 seats or more. Customers who signed before November 10, 2026 keep their previous price until renewal. Anything separately agreed takes priority.

The free trial lasts 2 weeks. If you stop during the trial, there is no charge.

The minimum term is 3 months. If you continue after the trial, you pay for the first 3 months up front by the invoice we issue. The minimum term runs from the start date on the invoice (for an invoice issued during the trial, the day after the trial ends).

After the minimum term, you can renew month by month, by recurring card payment or by invoice.

If you add seats during a period, you pay for those seats for the months left in the current period (part of a month counts as one month). Seat reductions apply from the next renewal.

Fees already paid are not refunded if you cancel or reduce seats during a period, except where required by law or where we are at fault.

If an invoice is not paid by its due date, we may suspend members' access.

Onboarding support is an optional service costing ¥22,000 once per company (tax included), paid by invoice separately from app fees.

12. Changes to these Terms

We may update these Terms. We will post the changes and the new effective date on this page. By continuing to use the Service after a change, you agree to the updated Terms.
