2. Scope and contract documents

These terms apply only to customers acting for professional purposes and are not a consumer offer. The customer representative confirms authority to bind the customer.

In descending priority, the contract consists of signed special terms or order, accepted quote, DPA, any SLA, accepted specification or statement of work, and these terms. A customer document applies only if KYEASY expressly accepts it in writing.

3. Services and scope

KYEASY may provide product discovery, UI/UX, architecture, Web and mobile development, API integration, SaaS and cloud, till, e-commerce, delivery and loyalty modules, documentation, testing, code audit, deployment, support and operations. Only deliverables, features, environments, dependencies, volumes and acceptance criteria stated in the order are included.

  • An estimate, prototype, demonstration or visual metric is not a performance or business-results commitment.
  • Changed requirements, defective source data or a new dependency may require a change order, additional time and fees.
  • Unless expressly stated, KYEASY owes professionally reasonable efforts, not a guarantee of the customer’s commercial, tax or regulatory outcome.

4. Customer and user duties

  • Provide timely, accurate, lawful and usable requirements, content, data, access, decisions and contacts.
  • Test deliverables and report a non-conformity precisely within the agreed acceptance process.
  • Use named accounts, protect credentials, restrict roles and report suspected access promptly.
  • Use the service lawfully, within documentation and purchased scope, without bypassing security, limits, audit trails or integrity controls.
  • Hold the necessary rights and legal grounds for supplied data and content, and keep sensitive or card data out of channels not designed for it.
  • Maintain customer-controlled equipment, networks, browsers and third-party services and perform customer-assigned exports or backups.

5. Accounts and acceptable use

The customer is responsible for activity under its accounts until a compromise is reported, except to the extent caused by KYEASY. It may not rent, resell or give the service to an outside party without written approval.

  • Prohibited conduct includes unauthorised access, unapproved security testing, malware, fraud, unlawful content, infringement, deliberate overload, unagreed mass extraction and reverse engineering beyond mandatory exceptions.
  • KYEASY may take a proportionate protective measure against an imminent threat, minimise impact and inform the customer as soon as security and law allow.

6. Prices, invoices and late payment

The order states final prices, currency, VAT, schedule and payment method. B2B prices are exclusive of tax unless stated otherwise. The public €1.00 per GB per month estimate, with a displayed 20 GB minimum, is indicative and excludes bespoke work, migration, third-party charges and unpurchased assistance.

Unless the order sets another date, invoices are due 30 days from issue. Subscriptions may be billed in advance for the ordered period. A reasoned dispute must be raised promptly and does not suspend payment of the undisputed part.

  • Late payment automatically bears interest at the European Central Bank’s latest refinancing rate plus ten percentage points, never below the statutory minimum.
  • A fixed €40 recovery charge is due per late invoice; documented reasonable additional costs may be claimed.
  • After ineffective notice, KYEASY may suspend the affected service proportionately without unnecessarily deleting data or obstructing statutory duties.

7. Term, renewal and termination

The order sets initial term and renewal. If a monthly cloud subscription says nothing else, it renews monthly; the customer may give non-renewal notice before the next due date, effective at the end of the paid period. A started period is not refundable unless KYEASY failed to perform or the parties agree otherwise.

Either party may terminate a material breach not cured within 30 days after written notice. The cure period does not apply to an incurable breach, serious unlawful use, deliberate security interference or persistent non-payment after notice, subject to applicable law.

8. Availability, maintenance and support

KYEASY maintains the service with reasonable professional care. Planned maintenance, a security emergency, the Internet, a third party or force majeure may affect availability. Uptime, on-call cover, response time or service credit applies only if stated in an SLA or order. KYEASY may reasonably evolve the service for security, compliance and maintainability, giving advance notice of material impact where practicable.

9. French cash-register provisions

Where applicable, Article 286 I-3° bis of the French General Tax Code requires inalterability, security, retention and archiving (ISCA). Since 21 February 2026, evidence may be an accredited-body certificate or an individual publisher statement matching the administrative template.

  • Evidence covers only the product, version, modules, options and conditions named in it. KYEASY claims no NF525, LNE or other certification without a valid matching document.
  • KYEASY supplies applicable evidence only after validating the covered scope. A demo, work in progress or unnamed module is not represented as covered.
  • The customer determines applicability, correctly configures taxes and flows, follows documentation, runs closures and archives, keeps evidence and does not alter controls.
  • A cancellation, correction or refund must add a trace and preserve the original. Do not edit the database, delete a log or bypass a control.
  • A customisation or third-party integration that may affect the compliance scope must be assessed before production and may require renewed validation or evidence.

10. Personal data, security and confidentiality

Each party complies with the GDPR for purposes it determines. An Article 28 DPA applies before production where KYEASY processes customer data, setting out instructions, security, subprocessors, transfers, assistance, audits and end-of-service operations.

Each party protects confidential information with at least the care used for its own equivalent information and uses it only for the contract. Information lawfully public, already known, lawfully obtained from a third party or independently developed is excluded. A legally required disclosure is limited and, where permitted, notified in advance.

11. Customer data, switching and end of service

The customer retains rights in its data and gives KYEASY a limited permission to host, copy, transmit and transform it to deliver, secure and support the service. The order identifies exportable data and digital assets, formats, known limits, fees and the switching process.

For data-processing services covered by the EU Data Act and where technically feasible, the switching initiation notice period is no more than two months, transition is normally no more than 30 days, and retrieval remains available for at least 30 days after completion. If an extension is technically necessary, KYEASY explains why and supplies an alternative timetable. Until 12 January 2027 a switching charge will not exceed direct costs; afterwards no switching charge applies in principle, without prejudice to a lawful early-termination charge.

Unless agreed otherwise, a reasonable standard export is available during the contract and for at least 30 days after termination. Active data is then deleted within a reasonable period and no later than 90 days, subject to law, documented instructions and controlled backup cycles in the DPA.

  • The customer must request and verify its export before access expires.
  • Unless an archiving service is expressly ordered, the customer remains responsible for keeping tax and accounting data after service ends.

12. Intellectual property

KYEASY and its licensors retain rights in software, tools, methods, templates, generic documentation, marks and pre-existing materials. Subject to payment, the customer receives a non-exclusive, non-transferable right during the contract to use the ordered service for internal professional purposes. Any assignment or licence of bespoke code, source, designs and deliverables must be stated in the order; otherwise no further rights pass. Open-source components remain under their licences.

13. Third-party services

Payment platforms, app stores, messaging services, APIs, infrastructure and other integrations remain subject to their provider’s terms. Unless expressly resold, KYEASY does not control their decisions, price or availability. KYEASY remains accountable for selecting and managing its own subprocessors under the contract and GDPR.

14. Warranty and liability

KYEASY addresses through support a reproducible failure to meet accepted specifications. This excludes misuse, unauthorised changes, an uncontrolled environment or third party, defective data or refusal of a necessary fix.

To the extent permitted by law, neither party is liable for indirect loss such as opportunity, reputation, margin or expected saving. KYEASY’s total liability for the same or related event is capped at the fees excluding tax paid for the affected service in the 12 months before the event.

The cap and exclusions do not apply where law forbids limitation, including fraud or gross negligence and personal injury, or to the customer’s payment duties. They do not deprive an essential obligation of substance. Special terms may give greater protection for an identified risk.

15. Force majeure

A party is not liable for delay caused by an event meeting the French-law test for force majeure. It notifies the other party, reasonably mitigates and resumes performance when possible. If essential prevention lasts more than 60 days, either party may terminate the affected part without compensation; completed services remain payable.

16. Governing law and disputes

French law governs. Before proceedings, the parties attempt in good faith to resolve a dispute for 30 days after detailed written notice. If unresolved and subject to mandatory rules, disputes between traders fall within the exclusive jurisdiction of the Commercial Court of Limoges, including urgent proceedings, third-party claims or multiple defendants.

17. Changes and general terms

KYEASY may change these terms prospectively. A material change to a current subscription is notified at least 30 days in advance, except for legal or security urgency. If it materially worsens the contract, the customer may reject it and terminate the affected service before the effective date. Invalidity of one provision does not affect the others; failure to exercise a right is not waiver; assignment and notices follow the order and applicable law.
