Terms and conditions of sale
Version in force as of 4 septembre 2026.
These terms and conditions of sale (“the Terms”) are entered into between MUCHA JACEK, a French sole trader (entrepreneur individuel) — SIREN 109 189 845, SIRET 109 189 845 00018, registered office 12 rue des Lilas, 60126 Longueil-Sainte-Marie, France (“the Provider”) and any natural or legal person placing an order on the site learn.jacekmucha.fr (“the Client”).
Placing an order implies unreserved acceptance of these Terms, in the version in force on the day of the order.
Article 1 — Purpose and scope
These Terms govern the sale of services falling within the activity registered under APE code 85.59A — Formation continue d’adultes, namely: applied language courses for working life (English and Polish) and technical-literacy workshops for adults, covering the vocabulary, the documentation and the computing concepts of the distributed-ledger field, sold and paid for directly by the learner or their employer, with no public funding, to the exclusion of any investment, legal or tax advice and of any digital asset service
One and the same business, under a single SIREN number, performs all the services described on the site, for the same clientele and under these single set of terms.
The regulated activities listed on the Code of practice page are excluded from the scope of these Terms and cannot be the subject of any order.
Article 2 — Services
The services, their content, their duration and how they are delivered are described on the course pages of the site and restated in the order summary. Those descriptions are contractual terms.
The Provider is under an obligation of means (obligation de moyens). No numerical result, exam pass, job offer, diploma or certification is guaranteed.
Article 3 — Prices
Prices are given in euro, all taxes included. The Provider is covered by the small-business VAT exemption of article 293 B of the French tax code: VAT is not applicable, no VAT is charged and none is recoverable.
The price that applies is the one displayed when the order is confirmed. Any travel costs, where they apply, are shown before confirmation and appear as a separate line in the summary.
Article 4 — Ordering
Orders are placed online as follows: selecting the services, viewing the basket, entering billing details, accepting these Terms, then a payment page showing the itemised lines, the total and the amount to be paid.
An order becomes firm only once the amount due at order has been received and the Provider has sent a confirmation e-mail carrying the order reference.
Article 5 — Payment
For any order below € 200, the full price falls due at the time of the order. From € 200, a deposit of 30 % falls due at the time of the order; the balance falls due at the latest by the halfway point of the package or track.
The accepted means of payment are shown on the payment page and set out in the payment policy.
Where a business client pays late, penalties equal to three times the French legal interest rate are due as of right, together with a fixed recovery indemnity of € 40 (art. L. 441-10 and D. 441-5 of the French commercial code).
Article 6 — Performance and lead times
The lead times applicable to each service are shown on the Delivery times page and restated at the time of order. Under article L. 216-1 of the French consumer code, the Provider performs the service on the agreed date or within the agreed period.
Failing performance within the agreed period, the Client may, after a formal notice that has gone unanswered for a reasonable time, terminate the contract under articles L. 216-6 et seq. of the French consumer code. Sums already paid are then refunded within fourteen days.
Article 7 — Right of withdrawal
A consumer Client has fourteen (14) days from the conclusion of the contract to exercise their right of withdrawal without having to give reasons (art. L. 221-18 of the French consumer code).
Where the Client expressly asks for performance to begin before the end of the withdrawal period, they keep the right to withdraw; they then pay an amount proportionate to what has been supplied (art. L. 221-25). If the service has been fully performed before the end of the period, with the Client's prior express agreement and their acknowledged waiver of the right of withdrawal, that right is lost.
Withdrawal is exercised by any unambiguous statement sent to contact@jacekmucha.fr, or using the model form reproduced on the Withdrawal and refunds page.
Article 8 — Cancellation and rescheduling by the Client
A session can be rescheduled at no cost if you give at least 24 hours' notice. Below that, it is counted against the package, save in a justified case of force majeure. A package or track already started can be stopped: the hours not used are refunded, less the hourly rate for the hours already delivered.
Article 9 — Client's obligations
The Client provides in good time the information, access and documents needed to perform the service, and warrants that they hold the necessary rights in the content they send.
Article 10 — Liability
The Provider's liability is limited to direct and foreseeable loss and may not exceed the total amount actually paid for the order concerned. No limitation applies in cases of wilful misconduct, gross negligence or personal injury.
Article 11 — Force majeure
Neither party is liable for a failure resulting from force majeure within the meaning of article 1218 of the French civil code. The service is then postponed by mutual agreement or refunded pro rata.
Article 12 — Confidentiality and personal data
Each party undertakes to preserve the confidentiality of the other's information. The processing of personal data is described in the privacy policy.
Article 13 — Complaints and mediation
Any complaint is sent by e-mail to contact@jacekmucha.fr. An acknowledgement is sent within 3 working days and a reasoned reply within 15 working days.
Under article L. 612-1 of the French consumer code, a consumer may use a consumer mediator free of charge; the Provider's membership of a mediation scheme is under way and will be published in the legal notice.
Article 14 — Governing law and jurisdiction
These terms and conditions of sale are governed by French law. Failing an amicable settlement, the dispute is brought before the competent French courts. A consumer may choose to bring proceedings before the court of their own place of residence.
