Terms of use and terms of sale

This document brings together two distinct sets of rules:

• the terms of use ("Terms of Use", Part I), which govern access to and use of the service, including free use;
• the terms of sale ("Terms of Sale", Part II), which govern subscriptions, credits, payment and cancellation.

Mixartisan is available at mixartisan.com. Mixartisan is a trading name operated by L&L4S, a French SAS with share capital of €100.00, registered office at 9 rue des Colonnes, 75002 Paris, France, registered with the Paris trade register under number 941 794 141 (the "publisher" — see the legal notice).

Using the service means accepting Part I. Subscribing to a paid plan additionally means accepting Part II.

🟢 As things stand, only Part I has anything to apply to: mixartisan.com is a presentation site, no paid plan is open, and no contract of sale is concluded through this site.

Mixartisan sells from France. The contract is governed by French law, and the consumer protections referred to below are those of the French Consumer Code.

Part I — Terms of use

1. Purpose

Mixartisan is a mixing and mastering guidance service. It provides a conversational assistant that analyses your tracks, explains the technical decisions behind them, suggests settings and teaches you the craft. It is aimed at musicians, producers and audio engineers, from beginners to seasoned professionals.

2. What the service is, and what it is not

🔴 Mixartisan advises; it does not do the work for you.

• The service analyses your files, explains decisions and recommends settings.
• It does not apply those settings, does not modify your projects and does not deliver a finished master on your behalf.
• You decide, you apply, and you keep full artistic and technical control of your tracks. You remain the sole decision-maker over your files.

The publisher is therefore under a best-efforts obligation (obligation de moyens), not an obligation to achieve a result: it takes reasonable care to provide a useful and accurate service, without guaranteeing any artistic, technical or commercial outcome. That outcome depends on your choices, your hardware, your plugins and your source material.

3. Access

Access requires an internet connection, a recent browser and, for some features, the ability to upload audio files. Meeting those requirements is your responsibility.

The service is open to adults and to legal entities. Anyone aged 15 to 18 may use it only with their legal guardian's agreement. The service is not intended for children under 15.

4. Your account

An account is required to use the service. You undertake to provide accurate information and to keep it up to date.

Your credentials are personal and confidential. You are responsible for keeping them safe and for any activity carried out from your account. Tell us without delay if you suspect unauthorised use.

An account may not be shared between several people, nor transferred to a third party.

5. Intellectual property

5.1 Your content stays yours

🔴 You remain the sole owner of your audio files, your tracks, your projects and anything you upload or create using the service.

Mixartisan acquires no ownership right over that content. The publisher does not claim it, exploit it, publish it, transfer it, or use it to train an artificial intelligence model or build a dataset.

You grant the publisher only a strictly technical, non-exclusive, royalty-free and temporary licence, limited to what is necessary to run the service: hosting your files, analysing them, transmitting them to the technical processors identified in the privacy policy, and returning the results to you. That licence ends when the content is deleted.

5.2 Your warranties on uploaded content

You warrant that you hold all rights and permissions required for the content you upload, including the rights of any performers, session musicians, authors and composers whose performance or work it contains. You undertake not to upload unlawful or infringing content, or content that violates third-party rights.

5.3 The service's own content

The service itself — interface, code, text, teaching method, visual identity and the "Mixartisan" name — remains the publisher's property. You receive a personal, non-exclusive, non-transferable right to use it for the duration of your subscription.

The explanations, analyses and recommendations the assistant produces on your tracks are yours to use freely in your work. You may not, however, extract them in bulk, resell them, or use them to build or train a competing service.

6. Prohibited conduct

You must not:

• attempt to access accounts, data or parts of the service not intended for you;
• use automated means to extract the service's content in bulk;
• disrupt the service or circumvent its limits, in particular credit metering;
• upload files containing malicious code;
• use the service for unlawful purposes or to infringe third-party rights.

7. Liability

In line with the best-efforts obligation set out in article 2, the publisher cannot be held liable for:

• the choices you make on the basis of the assistant's recommendations, or the sonic, artistic or commercial outcome of your tracks;
• occasional inaccuracy in an analysis or recommendation: an assistant built on artificial intelligence models can be wrong, and its opinion replaces neither your ears nor your judgement;
• loss of your files: this is not a backup service — always keep an original copy of your projects on your own storage;
• indirect damage (loss of opportunity, loss of clients, reputational harm, lost profit);
• interruptions caused by your connection, your equipment, force majeure or a third-party provider's failure.

Nothing in this document excludes the statutory guarantees owed to consumers (article 19), or the publisher's liability for gross negligence or wilful misconduct.

8. Availability and changes to the service

The service is available continuously, subject to maintenance, updates and incidents. The publisher endeavours to announce planned downtime in advance.

The service evolves: features may be added, changed or removed. Removing a substantial feature from a paid plan gives you the right to terminate at no cost.

9. Suspension for breach

In the event of a serious breach of these rules, the publisher may suspend access after a formal notice has gone unanswered for fifteen days, except in urgent cases involving security, manifestly unlawful content or non-payment. Suspension does not deprive you of the right to retrieve your content within a reasonable period.

10. Changes to the Terms of Use

These Terms of Use may be amended. Account holders are notified by email at least thirty days before a substantial change takes effect. Continuing to use the service after that date constitutes acceptance. If you do not accept, you may terminate at no cost.

Part II — Terms of sale

🔴 As things stand, the service is not open for sale. No plan is offered, no price is published, no payment is possible, and no contract has been concluded through this site. The provisions in this Part II will only apply once sales open.

The points still to be settled — prices, VAT treatment, billing frequency, minimum term, payment provider — will be published here before the first sale, not after. We would rather leave information visibly missing than invent a price list.

11. Scope

These Terms of Sale apply to every paid subscription. They apply to consumers within the meaning of the French Consumer Code as well as to business customers; provisions reserved for consumers are identified as such.

12. Subscription, credits and prices

The service runs on a subscription plus a credit system, with credits consumed by the most demanding operations (audio analysis, working sessions with the assistant).

• Plans, their contents, the number of credits included and current prices are those displayed on the pricing page at the time you subscribe. Prices are shown in euros. The applicable VAT treatment, and therefore whether prices are shown inclusive or exclusive of VAT, will be stated on the pricing page and here before sales open; we are not announcing it while it is not settled.

• Credits are attached to the account, non-transferable and not exchangeable for money.

• Credit validity — this rule is settled and will apply from the moment sales open:

  • credits included in a subscription are valid for the current billing period. They do not roll over: the balance is reset at each renewal, which re-credits the plan you subscribed to;
  • credits bought as a one-off top-up are valid for 12 months from the date of purchase;
  • on cancellation, unused included credits are lost at the end of the period already paid for; one-off top-ups remain usable until their expiry date, for as long as the account exists.

  This will be restated at the point of purchase and displayed permanently in your account area, along with the balance and expiry date of each batch of credits. An expiry that was not announced in advance would be an unfair term: that is precisely why it is set out here.

• Any price change is notified before it takes effect and applies only to subsequent periods. It gives you the right to terminate at no cost.

13. A refusal is never charged

When the engineer judges that a job cannot be done properly — mastering a mix that will not take it, for instance — it says so and explains why. No credit is deducted for that refusal.

You do not pay to be told yes. This is an operating rule of the service, and it binds the publisher.

14. Ordering and payment

The order is confirmed by payment. Payment is made online through the provider shown in the checkout flow; card details do not pass through the publisher's servers. The name of the payment provider, the payment methods accepted and the billing frequency will be published here before sales open — no provider has been selected to date.

An invoice is made available in your account area for each billing period.

15. Right of withdrawal (consumers)

If you are a consumer, you normally have fourteen days to withdraw from a distance contract, without giving reasons and without bearing any costs other than those provided for by law (Article L. 221-18 of the French Consumer Code). For a service or digital content contract, that period runs from the conclusion of the contract.

This right exists. The publisher does not conceal it and does not purport to remove it by contract.

How to exercise it: by any unambiguous statement addressed to the publisher at contact@mixartisan.com. When sales open, an online withdrawal function will also be provided in your account area, in accordance with Article L. 221-21 of the French Consumer Code; its exact location will be stated here.

16. Express waiver of the right of withdrawal

The service is digital content supplied immediately, with no physical medium: as soon as you subscribe, you get access to the assistant and can start spending credits.

Article L. 221-28(13) of the French Consumer Code removes the right of withdrawal for this type of supply, on three cumulative conditions:

1. you have given your prior express consent for performance to begin before the withdrawal period expires;
2. you have acknowledged that you will lose your right of withdrawal;
3. the publisher has provided you with confirmation of your agreement on a durable medium, in accordance with the second paragraph of Article L. 221-13.

That is why, at checkout, you are shown a separate, un-ticked checkbox reading:

"I expressly request immediate performance of the service and acknowledge that I will lose my right of withdrawal as soon as I first use it."

and the order confirmation email you then receive restates that agreement.

The same logic applies to services fully performed before the end of the withdrawal period (Article L. 221-25).

⚠️ Until all three conditions are met, your fourteen-day right of withdrawal remains intact. If you would rather keep it, do not tick the box: performance of the service will then be deferred until the period has expired.

17. No refunds

Once performance has begun on the conditions set out in article 16:

• a subscription period already started is not refundable, even in part;
• credits already spent are not refundable, the analysis having actually been carried out;
• unused credits are not refunded on cancellation; they remain usable until the end of the current period.

🔴 This rule does not apply where the law requires a refund, in particular: lack of conformity of the service, prolonged unavailability attributable to the publisher, enforcement of the statutory guarantees set out in article 19, or withdrawal by a consumer who has not validly waived that right under article 16. In those cases, a refund is due.

In addition, under Article L. 221-25 of the French Consumer Code:

• a consumer who withdraws after performance began at their express request pays only an amount proportionate to the service actually supplied up to the point of withdrawal;
• no sum is due from a consumer who withdraws if their express request for immediate performance was not properly collected, or if the publisher failed in its duty to inform them about the right of withdrawal.

18. Term, renewal and cancellation

The subscription runs for the term stated at sign-up and renews on the conditions stated there. The minimum term, the billing frequency and the renewal arrangements and notice period will be published here before sales open.

Online cancellation — Since the contract was concluded electronically, the publisher provides, in accordance with Article L. 215-1-1 of the French Consumer Code, a free online cancellation function that is easy, direct and permanently accessible from your account area, with no need to write or telephone. The publisher confirms receipt of your notification, then informs you on a durable medium of the date on which the contract ends and of the effects of cancellation.

Cancellation stops renewal; it does not give rise to a refund for the current period (article 17).

Cancellation by the publisher — The publisher may terminate for a serious breach not remedied on the conditions in article 9, or for non-payment. Deleting the account triggers erasure of your data within the periods set out in the privacy policy.

19. Statutory guarantees (consumers)

Consumers benefit from the statutory guarantees applicable to digital content and services, in particular the statutory guarantee of conformity under Articles L. 224-25-12 et seq. of the French Consumer Code, as well as the guarantee against hidden defects. These guarantees apply free of charge and independently of any commercial warranty.

Part III — Common provisions

20. Governing law and disputes

This document is governed by French law.

In the event of a disagreement, please contact the publisher first, at contact@mixartisan.com, so that an amicable solution can be sought. Failing agreement, any consumer may refer the matter free of charge to a consumer mediator. Membership of a mediation scheme will be taken out before the first sale and the mediator's details published in the legal notice; as things stand, no sales being open, no membership is in place.

Failing amicable resolution, the dispute will be brought before the competent French courts. Consumers retain the right to bring proceedings before the court of the place where they resided when the contract was concluded or when the harmful event occurred.
