Service terms
Effective 4 October 2026. These terms apply to services supplied by Lorenzo Colombani, trading as Lorenzo’s AI Studio, Hildesheimer Str. 248, 30519 Hannover, Germany. Contact: lorenzo.colombani@live.fr; +49 178 6376825.
1. Services and prices
The personal-training offers are: one 90-minute session for €180; a package of three 60-minute sessions for €480; and AI setup plus four 60-minute sessions for €900. They are live services, not accredited qualifications or subscriptions. The displayed checkout amount is the total payable for that purchase. No undisclosed charge is added after you order.
Business programmes, custom tools, extra work and external software costs require a separate written scope and price. Example budgets on those pages are not an agreement to build unspecified software. Third-party subscriptions are excluded unless expressly included.
2. Ordering and scheduling
For a fixed training offer, the paid order is accepted when Stripe confirms a successful payment. A preferred date is a request, not a confirmed appointment. We agree the actual dates by email. If I cannot provide the purchased service on mutually acceptable dates, you may choose a refund for the unprovided service.
I provide the service description, applicable terms and withdrawal information in a durable form with the scheduling confirmation before the service begins. Keep your Stripe receipt and that confirmation. An enquiry alone creates no payment obligation and does not reserve work.
3. Payments and international customers
Payments are collected on Stripe’s hosted page. Available cards and other payment methods depend on Stripe, the payment method and the customer’s location. The studio does not receive your complete card number or security code. Your bank or payment provider may apply its own currency-conversion charges.
Customers in Germany and France, the rest of Europe including non-EU countries, and major English-speaking markets including the US, UK, Canada, Australia and New Zealand may request services. Availability remains subject to applicable law and payment-provider eligibility. German supplies covered by §19 UStG use the German small-business exemption. Other transactions follow the tax rules applicable to their location and customer status; the German exemption is not a worldwide exemption. Billing information is collected for that assessment. Prices are not increased without your agreement.
4. Participation and AI tools
Bring an account you are authorised to use and non-sensitive or appropriately redacted examples. Do not share account passwords. Follow the relevant provider’s terms, licences and acceptable-use rules, plus your employer’s instructions and confidentiality obligations. Discuss paid plans and external costs with me before incurring them.
AI outputs may be incomplete or incorrect. Training teaches methods for using and checking them; it does not guarantee a particular business result or replace qualified advice. Review outputs before relying on them. I remain responsible for performing the agreed service with the care required by applicable law. Third-party terms do not remove my own contractual or data-protection obligations.
5. Cancellation, rescheduling and refunds
Contact me as soon as possible to request a change. We agree replacement dates according to availability. No blanket non-refundable fee or automatic no-show penalty is created by these terms. Your statutory withdrawal rights and other mandatory remedies take priority. Any separate cancellation arrangement must be clearly agreed and lawful.
If I cancel and we cannot agree a replacement, I refund the unprovided service. Refunds are normally returned through the original payment method. The statutory withdrawal rules below govern withdrawals; do not confuse a scheduling request with a withdrawal declaration.
6. Consumer withdrawal and early performance
Consumers generally have 14 days to withdraw from a distance service contract. Read the separate withdrawal notice and use any permitted clear declaration, including the online withdrawal function. Paying does not waive this right.
A session within the withdrawal period requires a separate express request to start early and the required information and acknowledgement. The right ends only after the agreed service is fully performed where the statutory conditions are satisfied. Completing one session does not fully perform a multi-session package. A proportionate charge following withdrawal applies only where the legal conditions are met.
7. Materials and custom work
You may use the materials supplied with your training for your own personal or internal business work. Do not resell or publicly distribute third-party material without the necessary permission. Ownership, source-code delivery, third-party components, support and hosting for custom tools are set out in the individual written scope.
8. Liability and mandatory rights
Nothing in these terms excludes liability that cannot lawfully be excluded, or restricts mandatory consumer rights. In particular, no blanket exclusion applies to intentional misconduct, personal injury or mandatory statutory remedies. Provider outages and AI limitations do not excuse obligations that the studio itself has undertaken.
9. French law and non-contractual claims
Contracts are governed by French law to the extent a valid choice is permitted. For consumers, this choice does not remove non-derogable protections of the law of their habitual residence. Applicable overriding mandatory rules remain effective, including the conflict-of-laws rules in Rome I where applicable. Non-contractual obligations follow the applicable conflict-of-laws rules, including Rome II where it applies; they are not automatically brought under this contractual choice.
10. Complaints and mediation
Please first describe your complaint by email so we can try to resolve it directly. Consumers may agree to independent mediation after a dispute arises, but mediation is not a condition for going to court and no settlement is compulsory. Mandatory consumer-redress rights remain unaffected. No membership of a particular mediation provider is represented by these terms.
Business customers: médiation conventionnelle préalable
For disputes concerning the formation, interpretation, performance or termination of a business contract, and where enforceable, the parties agree to attempt contractual mediation before ordinary court proceedings. A party sends a written dispute notice describing the issue and proposed resolution. The parties first allow ten calendar days for direct discussion, then attempt for a further ten days to appoint an independent mediator by mutual written agreement and agree the mediator’s fees and their allocation.
If no mediator is agreed within that period, either party may bring proceedings. Otherwise the parties participate in good faith for up to 30 calendar days from acceptance of the appointment, unless they agree in writing to extend it. Either may proceed after the mediator records failure or the period expires. This is an obligation to attempt the process, not to settle. Urgent or interim relief and steps necessary to protect limitation periods remain available; no automatic suspension of limitation is asserted. This mandatory pre-litigation procedure does not apply to consumers.
11. Jurisdiction
Consumers retain the courts available to them under mandatory jurisdiction rules. For business customers only, and only where the applicable rules permit a valid jurisdiction agreement, the competent courts of Paris have exclusive jurisdiction. This clause is subject to Brussels Ia, the Lugano Convention and other applicable jurisdiction instruments, as well as relevant national requirements, including Article 48 of the French Code of Civil Procedure where applicable. It does not override mandatory consumer forums.
12. Version and individual agreements
The version provided when you order applies to that contract. A later website update does not retroactively change it. An individually agreed written scope takes precedence on its specific service details, subject always to mandatory law.
