Thank you for using AeroX, the solution that turns your home trainer into a virtual wind tunnel.
These Terms of Use govern access to and use of the AeroX service.
By creating an account or using AeroX, you fully accept these terms.

1. Definitions

AeroX: the application published by SAS AeroX, a French simplified joint-stock company (société par actions simplifiée) with a share capital of €7,000, whose registered office is at 30 rue René Cassin, 21000 Dijon, France, registered with the Dijon Trade and Companies Register (RCS) under number 991 124 215 (see the legal notice). Depending on the context, “AeroX” refers to the application or to the company that publishes it.
Service: all features provided by AeroX (software, website, simulator, etc.).
User: any person using AeroX through an Account, namely:
- the rider (rider account): an adult individual acting for personal purposes, as a consumer;
- the bike fitter (bike fitter account): a professional, whether an individual (in particular a sole trader) or a legal entity, acting for the purposes of their business.
Consumer and professional: within the meaning of the preliminary article of the French Consumer Code.
Account: personal access allowing the User to use the Service after registration and, where applicable, payment of a subscription.

2. Purpose

These Terms of Use define the rights and obligations of AeroX and the User regarding the use of the Service.

3. Account Creation and Use

Access to AeroX requires the creation of a personal account.
The information provided during registration must be accurate and up to date.
Each account is strictly personal and non-transferable.
👉 Account sharing (loan, resale, or transfer of credentials) is prohibited and may result in suspension or deletion of the account.

4. Subscriptions and Usage

Full access to the Service requires payment of a subscription or specific plan.
Each subscription includes up to 30 hours of use per month.
If additional hours are needed, the User must contact AeroX (contact@aeroxbefaster.com) to obtain an extension or suitable offer.
AeroX reserves the right to charge additional fees or limit access in the event of excessive or disproportionate use.
Purchases (subscriptions, AeroX Diagnostic) are concluded directly with AeroX, which is the seller; payment is processed by the payment provider Stripe.

5. AeroX Diagnostic: Purchase, Duration, Withdrawal and Refunds

Content: the AeroX Diagnostic is digital content sold individually, supplied in dematerialised form in the AeroX application. It gives access to a protocol of guided sessions (position comparison, stability test) and to a recommendation report.
Supply: the diagnostic is supplied, and its performance begins, when its first session is started in the application, not at payment.
Duration: one purchase entitles the User to one diagnostic, usable for 30 days from the moment it is started in the application. It ends at the end of this period or when the User declares it finished; its results remain available. Restarting a diagnostic in progress does not extend this period.
Right of withdrawal: a User acting as a consumer has 14 days from the purchase to withdraw, without giving any reason, by writing to contact@aeroxbefaster.com. AeroX then refunds all sums paid, using the same payment method, no later than 14 days after the request.
Waiver: at checkout, by ticking the box provided for this purpose, the User accepts these Terms of Use, expressly requests immediate access to the diagnostic and acknowledges losing the right of withdrawal as soon as the first session is started, which marks the beginning of performance (French Consumer Code, Article L221-28 13°). Once the first session has been started, the diagnostic is no longer refundable under the right of withdrawal.
AeroX guarantee: in addition to the right of withdrawal, AeroX fully refunds the diagnostic, upon simple request to contact@aeroxbefaster.com, as long as no session has been completed, regardless of the purchase date, in particular if the User’s equipment is not compatible. As soon as the first session has been completed, the diagnostic is consumed and is no longer refundable.
Effect of a refund: any refund ends access to the corresponding diagnostic.
Legal guarantee: the no-refund rules above do not apply to the remedies under the legal guarantee of conformity (Section 9), which remain due in the event of a lack of conformity.

5a. Bike fitter plans: free trial, subscription and cancellation

This section applies to bike fitter accounts. Where it conflicts with sections 4 and 11, it prevails.

Plans: Essential, €20 excl. VAT per month plus €15 excl. VAT per analysis, billed at the end of each monthly period; Unlimited, €99 excl. VAT per month or €990 excl. VAT per year. Launch offer, reserved for the first 20 studios and subscribed by 31 December 2026: Unlimited at €69 excl. VAT per month until 31 December 2026, then €99 excl. VAT per month, or €690 excl. VAT for the first year, then €990 excl. VAT per year. Prices exclude taxes; VAT is applied under the rules in force.
Analysis: one client analysed with AeroX, counted once per rolling 30-day period. Further sessions with the same client during that period are not counted.
Subscription and installation: the bike fitter chooses a plan and saves a valid payment method; no subscription starts and nothing is charged at this stage. The subscription starts on the day the AeroX setup is installed at the bike fitter’s premises with the AeroX team, with a free trial. Without installation, nothing is ever charged. Before installation, the bike fitter can change plan or drop it at any time from the bike fitter account (“Drop this plan”).
Free trial: the first subscription starts with a 14-day free trial, from the day of installation. It is reserved for professionals, one trial per studio. Nothing is charged during the trial, and analyses made during the trial are not billed.
Availability of the plans: bike fitter plans are made available on 1 November 2026, with the version of the app that counts analyses. Nothing is charged before that date, including for an earlier subscription.
End of the trial: unless cancelled before the trial ends, the chosen subscription starts automatically at the end of the trial and the first payment is taken that day from the saved payment method. The trial end date is shown in the bike fitter account from installation.
Cancelling during the trial: at any time before the trial ends, from the bike fitter account (“Cancel the trial”). Nothing is then charged, and access remains open until the end of the trial.
Term and cancellation: subscriptions have no minimum term and renew automatically for each period (month or year). They can be cancelled at any time from the bike fitter account; cancellation takes effect at the end of the current, already paid period, with no prorated refund.
Changing plans: moving to a higher plan is immediate, with the difference prorated; moving to a lower plan takes effect at the end of the current period.
Failed payment: if a payment fails, access is kept for 7 days; after that, the account becomes read-only until payment is made. Amounts due remain payable.
Invoices: available in the bike fitter account (“Manage billing”).
Professionals: bike fitter plans are reserved for professionals acting for the purposes of their business; the right of withdrawal provided for consumers does not apply.

6. Service Operation

AeroX provides real-time aerodynamic analysis via webcam and connected home trainer.
AeroX does not guarantee uninterrupted service availability (maintenance, updates, improvements).
The User is responsible for their own equipment (home trainer, bike, camera, computer).

7. User Obligations

The User agrees to:

use AeroX in accordance with its intended purpose and with the licence granted to them (Section 8): sporting, personal and non-commercial use for a rider account; analysis of their own clients, as part of their bike fitting business, for a bike fitter account,
not use the Service for fraudulent or unlawful purposes, nor for commercial purposes beyond what the Bike Fitter Licence allows,
respect the usage limits described in Section 4,
not attempt to bypass the security of the Service, and comply with Section 8 (Intellectual Property and Software Protection).

8. Intellectual Property and Software Protection

Ownership: the AeroX software (macOS and Windows desktop applications, web and mobile companion application, in all their versions and updates), its artificial intelligence models (in particular the segmentation and pose estimation models, their weights, trained architectures and parameters), the training datasets, the calculation algorithms (frontal area, CdA, calibration), the documentation, the AeroX trademarks, logos and names, and the content of the website and the application belong exclusively to SAS AeroX, which holds all the related intellectual property rights. The User’s personal data is not covered: it is governed by Section 12.
Licences: subject to compliance with these Terms of Use, the User is granted, depending on the type of Account, one of the following two licences. Each is non-exclusive, non-transferable and non-sublicensable, and limited to using the application within the scope provided for by these Terms of Use, for the term of the corresponding subscription or purchase:
- Rider Licence (rider account): a personal, non-commercial right of use, attached to the User’s Account;
- Bike Fitter Licence (bike fitter account): a professional right of use, attached to the bike fitter account, limited to analysing their own clients as part of their bike fitting business. The bike fitter may give their clients the reports and results produced for them; they may not make the application or the models available to third parties, nor resell them.
No transfer of ownership: neither licence transfers any ownership; all rights not expressly granted are reserved.
Prohibitions: subject to the exceptions provided for by Article L122-6-1 of the French Intellectual Property Code (CPI), the User may not, directly or through a third party:
- copy, extract, isolate, export or reuse the AeroX artificial intelligence models or their weights outside the application;
- integrate them into any other software, application (including mobile, iOS or Android) or service;
- use them to train, distil, fine-tune or evaluate another model;
- decompile, disassemble or reverse engineer the software or the models, or circumvent, disable or alter their technical protection measures (encryption, signature, etc.);
- reproduce, modify, translate, adapt, distribute, rent, sell or make available to third parties all or part of the software, models, datasets, algorithms or documentation.
Statutory exceptions: this section does not deprive the User of any right granted by Article L122-6-1 of the CPI, in particular, under the conditions and within the limits it sets, making a backup copy and decompiling where indispensable for the interoperability of the software with independently created software. Information needed for interoperability can be requested at contact@aeroxbefaster.com.
Sanctions:
- in the event of a breach of this section, AeroX may suspend access to the Service or terminate the licence and the Account, after a formal notice sent by email has remained without effect for 15 days;
- in the event of a particularly serious breach, in particular extracting, exporting or reusing the artificial intelligence models or their weights outside the application, using them to train another model, or circumventing the technical protection measures, AeroX may terminate the licence and the Account immediately, without prior formal notice; the User is informed by email of the reason for the termination;
- what happens to sums already paid is governed by Section 11;
- these measures are without prejudice to any action by AeroX, in particular for infringement (Articles L335-2 and L335-3 of the CPI), and to any claim for damages.

9. Legal Guarantee of Conformity

As the seller, AeroX is bound towards a User acting as a consumer by the legal guarantee of conformity for digital content and services provided for in Articles L224-25-12 et seq. of the French Consumer Code.
AeroX Diagnostic (single supply of digital content): AeroX is liable for any lack of conformity that becomes apparent within two years from the supply of the diagnostic, that is, from the start of its first session (Section 5). Any lack of conformity that becomes apparent within twelve months of that supply is presumed to have existed at the time of supply, unless proven otherwise.
Subscriptions (continuous supply): AeroX is liable for any lack of conformity that becomes apparent throughout the term of the subscription.
Remedies: in the event of a lack of conformity, the User is entitled to have the digital content or service brought into conformity free of charge. Failing that, in particular if bringing it into conformity is impossible, is not done within a reasonable time or does not remedy the defect, the User may obtain a price reduction or the termination of the contract, under the conditions provided for by those articles.
How to proceed: the User sends the request to contact@aeroxbefaster.com, describing the defect observed.

10. Limitation of Liability

AeroX is bound by an obligation of means: it makes reasonable efforts to provide a reliable Service, without guaranteeing uninterrupted or error-free operation (maintenance, updates, improvements).
The measurements provided by AeroX (frontal area, CdA, scores) are estimates. Their quality also depends on factors beyond AeroX’s control, in particular the camera, the User’s equipment (computer, home trainer, sensors), lighting and setup. AeroX is not liable for any misinterpretation of the results, nor for any use of the Service that does not comply with its intended purpose or with these Terms of Use.
AeroX is not liable for indirect damage.
Towards a User acting as a professional, AeroX’s liability is limited to the amount paid for the current period.
Express clause: no provision of these Terms of Use excludes or limits the legal guarantee of conformity (Section 9), the warranty against hidden defects (Articles 1641 et seq. of the French Civil Code), AeroX’s liability for personal injury, or its liability for gross negligence or wilful misconduct.

11. Termination and Suspension

The User may cancel their subscription at any time.
AeroX may suspend or terminate an Account in the event of fraud, breach of these Terms of Use or abusive use, after a formal notice sent by email has remained without effect for 15 days, or immediately in the event of a particularly serious breach, in particular those referred to in Section 8. The User is informed by email of the reason for the measure.
Sums already paid: if AeroX terminates for breach by the User, sums corresponding to services already provided and to the period already elapsed remain due. The part of the price corresponding to the remaining term of a subscription, or to a purchase not yet used (in particular a diagnostic with no session completed), is refunded to the User, without prejudice to any damages that may be claimed to compensate for the loss suffered.

12. Personal Data

AeroX collects and processes certain data (e.g. performance metrics, email) to provide the Service.
Such data is handled in accordance with our Privacy Policy.

13. Governing Law, Disputes and Language

These Terms of Use are governed by French law. Where the User is a consumer residing in another Member State of the European Union, this choice does not deprive them of the protection afforded by the mandatory provisions of the law of their country of residence.
Amicable complaint: in the event of a dispute, the User is invited to first send a written complaint to contact@aeroxbefaster.com, in order to seek an amicable solution. This step is not a prerequisite for taking legal action.
Competent court: a User acting as a consumer may bring proceedings, at their choice, before one of the courts with territorial jurisdiction under the French Code of Civil Procedure or before the court of the place where they lived when the contract was concluded or when the harmful event occurred (French Consumer Code, Article R631-3). A consumer residing in another Member State of the European Union may bring proceedings before the courts of their place of domicile.
Professionals: where the User is a professional, any dispute falls within the jurisdiction of the Commercial Court of Dijon (tribunal de commerce de Dijon), under the conditions provided for by Article 48 of the French Code of Civil Procedure.
Language: these Terms of Use are drafted in French. Translations may be provided as a courtesy; in the event of any discrepancy, the French version prevails.
