TurbineTrail

Terms of sale

Last updated: October 22, 2026

These terms of sale (the “Terms of Sale”) govern the subscription to the paid plans of the TurbineTrail service, published and sold by Blade Expert SARL (“we”), by a customer company (the “Customer”, “you”).

They supplement the terms of service, which govern the use of the service. For subscription, price, billing and termination, these Terms of Sale prevail.

2. Business customers

The plans are reserved for professionals, for the needs of their business. The administrator who subscribes declares that they have the authority to bind the Customer.

As the contract is concluded between professionals, no right of withdrawal applies.

3. Plans and quantities

  • Provider: subscription billed per administrator and per inspector of the workspace (a “seat”); readers are free and unlimited. A user who is a member of several workspaces counts in each of them.
  • Operator: the Consultation plan is free; it allows the operator to describe its assets and view the events that partners share with it. The Fleet plan also allows it to create its own events, add records to them, share them or entrust them to a partner, add records to the events a partner entrusts to it, and provides the consolidated view. It is billed per wind turbine in the operator's assets; a wind turbine shared by a provider counts once, as soon as it is attached to one of the operator's wind turbines or added to its assets.

The billed quantity follows the workspace: it is updated with every change (member invited or removed, role changed, wind turbine added or deleted).

Prices are in euros, excluding taxes. VAT is added at the applicable rate according to the Customer's address and VAT number; a Customer established in another member state of the European Union with a valid VAT number is invoiced without VAT, under the reverse-charge mechanism.

We may change our prices. Any increase is notified to the administrators by email at least 30 days in advance and applies from the next renewal; a Customer who refuses it may cancel before that date.

5. Free trial, complimentary access and promotion codes

Each workspace benefits from a 30-day free trial, without any payment method: from sign-up for a provider, from the first activation of the Fleet plan for an operator. A workspace benefits from only one trial.

We may grant free access for a fixed period, in particular to companies that test the service, and offer promotion codes, which the Customer enters at payment. The discount and duration of each code are shown before payment.

A subscription taken out during the trial or complimentary access is only billed when they end.

6. Subscription

An administrator subscribes from the Subscription page of the workspace, by choosing monthly or annual billing and accepting these Terms of Sale. Payment is made on the secure pages of our payment provider, Stripe: we never have access to card or bank account details.

The contract is concluded when the payment is confirmed or, during a trial, when the payment method is saved. A confirmation is sent by email.

7. Billing and payment

The subscription is payable in advance, at the start of each monthly or annual period, by the payment methods offered at subscription (card, SEPA Direct Debit). No discount is granted for early payment.

Invoices are issued electronically, sent by email and available at any time in the customer portal.

A seat or wind turbine added during a period is billed pro rata for the remaining time: immediately for an annual subscription, on the next invoice for a monthly subscription. A removal gives rise to a pro rata credit, applied to the following invoices and not refunded. Switching from monthly to annual billing, or the reverse, is done from the customer portal, with a pro rata calculation.

8. Non-payment

If a payment fails, new attempts are made and the administrators are notified by email. Without settlement within 7 days, a provider's workspace becomes read-only and an operator's Fleet plan is paused, until payment. The subscription is cancelled if the attempts remain unsuccessful. No data is deleted for non-payment.

Any amount unpaid when due automatically bears late-payment penalties at three times the French legal interest rate, together with a fixed recovery fee of 40 euros (articles L. 441-10 and D. 441-5 of the French Commercial Code).

9. Term, renewal and cancellation

The subscription is concluded for a period of one month or one year, tacitly renewed for the same duration.

The Customer may cancel at any time from the customer portal: cancellation takes effect at the end of the current period, already paid, without refund. Deactivating the Fleet plan schedules the end of its subscription in the same way.

Closing the workspace, or deleting the account of its last member, ends the subscription immediately, without refund of the current period.

10. Without a subscription: read-only

At the end of the trial, complimentary access or subscription, without a new subscription, a provider's workspace becomes read-only and an operator's Fleet plan reverts to the Consultation plan: its events and records become read-only, its assets remain editable. The data is kept.

In read-only mode, members view the workspace data, manage members and invitations, and can subscribe, request an export of their data and close the workspace; they can no longer create or edit wind farms, wind turbines, events, records, files, partners or shares.

11. Changes to the Terms of Sale

We may change these Terms of Sale. Any substantial change is notified to the administrators by email at least 30 days before it takes effect; a Customer who refuses it may cancel before that date.

12. Governing law and disputes

These Terms of Sale are governed by French law. They are written in French; in the event of a discrepancy with a translation, the French version prevails.

In the event of a dispute, the parties first seek an amicable solution. Failing that, exclusive jurisdiction is granted to the courts of the registered office of Blade Expert (Arras), including in the event of multiple defendants or third-party claims.
