Terms of Use and Sale — Carbonix

Last updated: 24 October 2026

1. Purpose

These terms govern the use of Carbonix and the purchase of its subscriptions. They cover the carbonix.me website, the app.carbonix.me portal, the Carbonix BTP, Carbonix Bio and Carbonix PGES modules, and the Carbonix apps (Android, iPhone and iPad, Windows, macOS).

Carbonix is published by Ets Expertise Web Marketing (see the legal notice), hereinafter "Carbonix" or "we". By creating an account, you accept these terms. If you act on behalf of an organisation, you confirm that you are authorised to bind it.

2. The Carbonix account

• A single account gives access to all subscribed modules.
• You must provide accurate information and keep your password confidential. We recommend enabling two-factor authentication.
• You are responsible for what is done with your account. If you think someone else is using it, sign out the device concerned (My account → My devices), change your password and let us know.

3. The services

• Carbonix BTP: carbon footprint of construction sites and projects.
• Carbonix Bio: forest inventory, biomass and sequestered carbon.
• Carbonix PGES: monitoring and evaluation of environmental and social management plans (ESMP).

The features and limits of each plan (number of projects, users, storage…) are described at carbonix.me/en/tarifs. Our services evolve: a feature may be added, changed or removed. If a change significantly reduces a paid plan in progress, you may cancel it and get a refund for the remaining period.

4. Plans, prices and payment

Plans

Each module offers a free plan and paid plans, monthly or yearly. Bundles (several modules) and Enterprise offers on quotation may exist. Prices are shown at carbonix.me/en/tarifs, in euros or CFA francs, all taxes included.

Payment

• By bank card (Stripe): the subscription renews automatically at each due date, and the card is charged the same amount.
• By Mobile Money (FedaPay): an invoice is issued at each due date. You receive email reminders: 30 days before for a yearly subscription, then 7 days before, 3 days before and on the day.

An invoice is available for each payment, in My subscription.

Late payment

If a renewal is not paid, you keep access for 3 days after the due date. After that, your account returns to the module's free plan. Your data is kept. Features beyond the free plan are simply locked until payment.

Carbonix apps

Subscriptions are not purchased in the apps. They are managed on carbonix.me and apply immediately to all your apps.

5. Changing plan or cancelling

• Upgrading: takes effect immediately, prorated over the current period.
• Downgrading or cancelling: takes effect at the end of the period already paid. Nothing is charged afterwards. You can withdraw the cancellation as long as the period has not ended.

You can cancel at any time, in My subscription in each module.

6. Refunds

A subscription period that has started is not refunded: a cancellation takes effect at the end of the period already paid (section 5). The exceptions are the case set out in section 3 (significant reduction of a plan in progress) and cases where applicable law requires a refund.

7. Your data and content

• Your data belongs to you. You only authorise us to host and process it to provide the service.
• You can export it at any time (Excel, CSV, PDF depending on the module).
• If it includes information about other people, you must have the right to collect and share it.
• The processing of personal data is described in the privacy policy.

8. Calculation results

Carbonix calculates emissions, biomass, carbon and indicators using recognised methods and the factors available. These results are estimates that depend on the data entered. It is your responsibility to check them before using them, in particular in an official report, a certification or a regulatory process.

9. Acceptable use

You agree not to:

• use Carbonix for any illegal activity;
• attempt to access other users' accounts or data;
• disrupt the service or circumvent its technical limits;
• resell access to the service without our agreement.

In the event of a serious breach, we may suspend the account after notifying you, except in a security emergency.

10. Availability

We do our best to keep Carbonix available and to back up your data every day. Interruptions may occur for maintenance or in the event of an incident. Unless a specific Enterprise contract says otherwise, we do not guarantee a precise availability rate.

11. Liability

Our liability is limited to direct and foreseeable damage. It may not exceed the amounts you paid us over the last 12 months. This limit does not apply in the event of gross negligence or wilful misconduct, nor where applicable law prohibits it.

12. Account deletion

You can delete your account at any time: My account → Delete my account. Deletion takes place 30 days after the request, and you can cancel it until then. Paid renewals stop as soon as you make the request. Invoices are kept for accounting purposes. Details are at carbonix.me/en/suppression-compte.

13. Changes to these terms

We may change these terms. Significant changes are announced by email at least 30 days before they take effect. If you do not accept them, you may cancel before that date.

14. Governing law and disputes

These terms are governed by the law of Benin. In the event of a dispute, we first seek an amicable solution: write to contact@carbonix.me. Failing that, the courts of Cotonou have jurisdiction, subject to the protective rules applicable to consumers.
