Terms of sale and use

These terms govern the use of the levelingtower.com website. By accessing or using the website, you agree to be bound by these terms as well as any applicable law or regulation.

These terms come with our privacy policy. If you do not agree, do not use the service.

The content of this site is protected by applicable copyright and trademark law.

Leveling Tower is a Japanese language learning application: level-based progression through a tower, varied learning quizzes, a spaced repetition system (SRS) so you never forget, a searchable dictionary of kana, kanji, vocabulary and grammar, and detailed progress tracking.

The service is accessible for free, with a daily usage limit that restricts your learning activity. Paid plans remove this limit.

The exact scope of each plan may change; see the section Subscription and payment.

You must be at least 15 years old to create an account. Below that age, signing up requires the consent of a holder of parental authority, in accordance with French regulations on the protection of minors' data.

The information you provide when signing up must be accurate and kept up to date.

Your credentials are personal: you are responsible for keeping them confidential and for any activity carried out from your account. Notify us without delay in the event of unauthorised use.

You can delete your account at any time from your settings.

Three paid plans are available: Monthly Premium (€6.99 per month), Annual Premium (€59.99 per year) and Lifetime access (€149.99 as a single payment). Applicable prices are those shown at the time of order, in euros and inclusive of all taxes. VAT is not applicable, article 293 B of the French General Tax Code.

Payments are processed by Stripe. No card data is stored on our servers.

• Monthly and annual subscriptions renew automatically at each due date, at the rate then in effect, until you cancel. Lifetime access is not a subscription, so it neither renews nor can be cancelled.
• You can cancel online at any time, from the billing portal available in your settings, in accordance with article L215-1-1 of the French Consumer Code. Cancellation takes effect at the end of the period already paid for: you keep access until that date, after which your account reverts to the free plan.
• Renewal of the annual subscription - in accordance with article L215-1 of the French Consumer Code, we notify you by email, at the earliest three months and at the latest one month before the end of the current period, of your right not to renew. If this notice does not reach you within that window, you may cancel free of charge at any time from the renewal date, and any amounts paid after that date will be refunded.
• Price changes - our prices may change over time. A change has no effect on a period already paid for; you are notified by email at least thirty days before it takes effect on your subscription, and you may cancel before the renewal date if it does not suit you.
• Right of withdrawal - you generally have fourteen days to withdraw. As the service is digital content supplied immediately, you lose this right only if, at the time of order, you expressly requested immediate performance and acknowledged losing your right of withdrawal (article L221-28, 13° of the French Consumer Code). Absent that double agreement, the fourteen-day period remains available to you. In any case, contact us if there is a problem: we review refund requests in good faith.
• Statutory conformity guarantee - the service falls under articles L224-25-12 et seq. of the French Consumer Code. You benefit from the statutory conformity guarantee, free of charge and independently of these terms: in the event of a defect, you may request that it be brought into conformity or, failing that, a price reduction or termination of the contract.
• In the event of persistent payment failure, access to paid features may be suspended until the situation is resolved.

When using Leveling Tower, you agree not to:

• share your account or credentials with third parties;
• automatically extract the learning content from the service;
• disrupt the operation of the service (deliberate overload, intrusion attempt) or attempt to circumvent its limitations;
• use the service for unlawful purposes or to infringe the rights of others.

Failure to comply with these commitments may result in the suspension or closure of your account (see Termination).

The service, its brand, its interface and its code are our property or that of our licensors.

A subscription grants a personal, non-exclusive and non-transferable right to use the service. It transfers no ownership of the content or the technology behind it.

All parts of the site - text, interfaces, logos - are protected by intellectual property law. Reproduction or reuse without prior permission is prohibited. Part of the learning content (kanji, vocabulary) comes from third-party databases used under licence; the details of the sources and applicable licences are listed on the Credits.

We check the learning content carefully, but a language database of this size may still contain errors or inaccuracies (translation, reading, example). Let us know about any error you spot: we will correct it as soon as possible.

If you send us comments, questions or suggestions for improvement, you allow us to use them freely to develop and improve the service, without financial compensation. We will not disclose your identity in connection with this feedback without your consent.

The service may contain links to third-party websites or services that are not owned or controlled by us. We have no control over their content, privacy policies or practices, and disclaim any liability in that respect. We encourage you to review the terms and privacy policy of any third-party site you visit.

We strive to keep the service continuously available and free of errors, without being able to guarantee either. Interruptions may occur for maintenance or for technical reasons beyond our control.

The features of the service may change, be added or be removed. If a change substantially reduced a paid plan you are currently on, you could cancel it and be refunded on a pro-rata basis for the unused period.

If you are a consumer, our liability applies under ordinary law: these terms neither exclude nor cap it in any way, and your rights under the statutory conformity guarantee and the guarantee against hidden defects remain intact.

If you use the service in a professional capacity, and to the extent permitted by law, our total liability is capped at the amounts you have actually paid us during the twelve months preceding the event giving rise to the claim, and we are not liable for indirect damages (loss of data, profits or opportunities).

Leveling Tower is a learning aid. No particular result can be guaranteed: your progress depends on your practice.

In all cases, nothing in these terms excludes or limits any liability that cannot be excluded or limited under French law - in particular in the event of fraud, gross negligence or personal injury.

You can close your account at any time from your settings. This permanently deletes all your data.

We may suspend or terminate an account in the event of a breach of these terms, after notice and a reasonable period to remedy it. Except in the event of a serious breach (fraud, security breach, unlawful use), in which case the measure may be immediate.

Amounts already paid for a service that has been provided remain due; if we terminate the contract through no fault of yours, the unused portion of the period paid for is refunded on a pro-rata basis.

These terms may be updated, in particular to reflect a legal or technical change. The last-updated date appears at the top of the page; any substantial change will be notified to you by email at least thirty days before it takes effect, and you may then cancel free of charge if it does not suit you. The terms that apply remain those in force at the time of your purchase until that date.

These terms are governed by French law.

The fact that we do not enforce a right or provision of these terms on a given occasion does not waive our ability to enforce it later.

If a provision of these terms is held invalid or unenforceable, the remaining provisions continue to apply in full.

In the event of a dispute, an amicable solution will be sought first: send us a written complaint at levelingtower@gmail.com.

The European ODR platform was discontinued on 20 July 2025; the list of consumer dispute resolution bodies in EU member states is available at consumer-redress.ec.europa.eu/dispute-resolution-bodies.

Failing agreement, the French courts have jurisdiction, subject to the mandatory rules applicable to consumers.
