Terms and conditions of sale

Last updated: 22 July 2026

1. Purpose and scope

These terms and conditions of sale (the "Terms") govern the supply of the software applications published by Tropic (the "Services") and all contractual relations between Tropic and its customers.

The Services are intended exclusively for professionals acting in the course of their business. Accordingly, the provisions of the French Consumer Code, including the right of withdrawal, do not apply.

Subscribing to any plan constitutes full acceptance of these Terms.

3. Description of the Services

Tropic publishes web applications for building services (MEP) design offices, in particular Tropic Planning (project scheduling) and Tropic Estimating (cost estimating). The Services are accessed online through a browser, with no installation required.

The Services are decision-support tools. They are not intended to replace the Customer's professional expertise, verifications or obligations.

Tropic reserves the right to develop the features of the Services. Substantial changes are communicated to the Customer by any appropriate means.

4. Plans and pricing

Applicable prices are those displayed on the website on the day of the order. They are expressed in euros and are net prices: VAT not applicable, Article 293 B of the French tax code.

Tropic reserves the right to change its prices. Any change is without effect on orders in progress and, for subscriptions, takes effect only at the end of the current period, subject to prior notice to the Customer.

5. Ordering and payment

Orders are placed online through the payment provider Stripe, or by invoice following an accepted quotation.

Online payments are due immediately. Invoiced amounts are payable within thirty (30) days of the invoice date, unless otherwise agreed.

In accordance with Article L. 441-10 of the French Commercial Code, late payment automatically incurs penalties calculated at the European Central Bank rate plus ten points, together with a fixed recovery indemnity of forty (40) euros.

Tropic never has access to the Customer's banking details, which are handled directly by the payment provider.

6. Trial period

The "Trial" plan grants access to the Services for fourteen (14) calendar days from the date access is provided, within the usage limits stated on the Pricing page.

This plan is a single, non-renewable and non-refundable payment. On expiry, access is automatically suspended without notice or compensation. The Customer may subscribe to a paid plan at any time.

7. Term, renewal and termination

Subscriptions are entered into for a term of one (1) month, renewed by tacit agreement, with no minimum commitment.

The Customer may terminate at any time; termination takes effect at the end of the current period. Sums paid for the period already started remain due to Tropic.

Tropic may suspend or terminate access in the event of non-payment, use contrary to these Terms, or serious breach, after formal notice remaining without effect for fifteen (15) days, save in cases of urgency or security risk justifying immediate suspension.

8. Access and availability

Tropic implements reasonable means to ensure the Services are accessible, without guaranteeing continuous or error-free availability.

Access may be interrupted for maintenance, updates, or due to third parties (hosting provider, network operators, infrastructure suppliers). Tropic endeavours to limit such interruptions and to give notice of scheduled ones.

The Customer is responsible for its own internet connection, equipment and browser compatibility.

9. Customer obligations

The Customer undertakes to:

  • provide accurate information when subscribing;
  • keep its credentials confidential and report any unauthorised access without delay;
  • use the Services in accordance with their purpose and applicable regulations;
  • refrain from accessing, decompiling, reproducing the source code or circumventing its protections;
  • refrain from reselling, sub-licensing or making the Services available to third parties.

The Customer, as a qualified professional, remains solely responsible for the data it enters, for verifying the results produced by the Services, for their suitability to its project, and for decisions taken on that basis.

10. Limitation of liability

Tropic is bound by an obligation of means in performing these Terms.

The Services produce calculations, schedules and estimates from data entered by the Customer and from configurable assumptions. These results constitute decision support and shall not engage Tropic's liability as to their accuracy, completeness or relevance to any given project. It is for the Customer to check them before any use, in particular before submitting a bid, a contractual document or a construction document.

Tropic shall not be liable for indirect damages, including loss of revenue, loss of business, loss of opportunity, reputational harm or commercial prejudice.

In any event, and save in cases of wilful misconduct, gross negligence or personal injury, Tropic's liability is capped at the total amount actually paid by the Customer during the twelve (12) months preceding the triggering event.

Nothing in these Terms shall operate to exclude Tropic's liability where the law prohibits it.

11. Customer data and backups

Data entered by the Customer remains its property. Tropic refrains from any use unrelated to the provision of the Services.

Tropic implements reasonable backup measures. Nevertheless, the Customer is advised to keep its own exports of important data and documents; the Services provide export functions in common formats.

On termination, the Customer has thirty (30) days to export its data, after which it may be deleted.

12. Intellectual property

The Services, their code, interfaces, databases and the Tropic trademark remain the exclusive property of Tropic.

Subscription grants the Customer a personal, non-exclusive and non-transferable right of use, limited to the term of the plan subscribed and the number of users provided for.

13. Personal data

The processing of personal data is described in the privacy policy. For data processed on behalf of the Customer within the Services, Tropic acts as a processor within the meaning of the GDPR.

14. Force majeure

Tropic shall not be liable for non-performance due to an event of force majeure within the meaning of Article 1218 of the French Civil Code, including major failures of networks, hosting services or infrastructure providers.

15. Amendments to the Terms

Tropic may amend these Terms. The applicable version is the one in force on the day of the order. For subscriptions, any substantial amendment is notified to the Customer, who may terminate free of charge if it refuses.

16. Governing law and jurisdiction

These Terms are governed by French law.

In the event of a dispute, the parties shall endeavour to reach an amicable settlement. Failing agreement within thirty (30) days, express jurisdiction is conferred on the competent courts of Paris, notwithstanding multiple defendants or third-party proceedings.
