Terms of use

Version: 1.0 — Last updated: 15 September 2026

Translation. This English version is provided for information. The French version is the binding text and prevails in the event of any discrepancy.

Article 1 — Purpose and publisher identification

These terms of use (the "Terms") govern access to and use of the Farygo mobile application and website (the "Application"), which monitors air fares on the routes a user tracks and alerts them when a price falls below a reference threshold.

The Application is published by:

CHAINIT, a société par actions simplifiée unipersonnelle (SASU) whose registered office is at 5 rue Alphonse Haussaire, 95880 Enghien-les-Bains, France, registered with the Pontoise Trade and Companies Register under number 831 544 168 — establishment SIRET 831 544 168 00022, APE code 62.02A, VAT number FR96831544168 (the "Publisher").

  • Publication director: the President of the company.
  • Contact: privacy@farygo.com
  • Host: Amazon Web Services EMEA SARL, 38 avenue John F. Kennedy, L-1855 Luxembourg.

Article 2 — Acceptance of the Terms

Creating an account constitutes full acceptance of these Terms. A user who does not accept them must not use the Application.

The version of the Terms accepted and the date of that acceptance are recorded. Any substantial new version is brought to the user's attention and must be accepted in order to continue using the Application.

Article 3 — Description of the service and its limits

3.1 Nature of the service

The Application is an information and fare-monitoring service. It collects fares from air travel data providers, computes a statistical reference from them, and notifies the user when an observed fare falls below that reference.

3.2 No travel sale or booking

The Publisher is neither a carrier, nor a travel agency, nor a booking intermediary. The Application allows no flight booking and no ticket payment within it, and the Publisher collects no sum in respect of any travel. All bookings are made exclusively with the airline or booking platform chosen by the user, on that provider's own terms.

This exclusion does not concern the subscription to the Application itself, which is a paid service governed by Articles 6 to 10 below.

3.3 Reliability of displayed prices

Displayed fares come from third-party sources, vary constantly, and may become out of date between collection and consultation. They are indicative and do not constitute a contractual offer. Only the price displayed by the seller at the time of booking is binding. The Publisher does not guarantee the completeness, accuracy or availability of the fares presented.

3.4 Redirection and affiliate links

The Application may redirect the user to third-party sites, including through affiliate links that pay the Publisher. That remuneration does not influence the fares displayed nor the order in which they appear: ranking is based solely on price and on the user's search criteria. The Publisher exercises no control over third-party sites and disclaims all liability for their content and terms.

Article 4 — User account

The user must be at least 15 years old and provide accurate information when creating an account.

The user is responsible for keeping their credentials confidential and for all activity carried out from their account. The two-factor authentication offered in the settings is recommended. Any unauthorised use must be reported without delay to the contact address.

The user may delete their account at any time from the Application's settings.

Article 5 — Alerts

Alerts are sent by email and, where applicable, by notification, according to the user's preferences.

The Publisher guarantees neither the timing nor the successful delivery of alerts: their delivery depends on third-party services (email providers, app stores, carriers) and on factors beyond its control. The user acknowledges that a reported fare may no longer exist by the time the alert is read.

The user may change their preferences or turn alerts off at any time.

Article 6 — Plans and subscriptions

The Application offers free access and paid subscriptions.

Free access — up to 2 routes tracked at a time, a limited monitoring window, and delayed alert delivery.

Paid subscriptions — up to 10 routes tracked at a time, an extended monitoring window, and alerts delivered without delay. The plans and their prices, inclusive of all taxes, are as follows:

PlanMonthlyAnnual
Standard€3.99 incl. VAT€39.99 incl. VAT
Premium€5.99 incl. VAT€49.99 incl. VAT

Prices are stated in euros, inclusive of all taxes, the applicable VAT being that of the user's country of residence. The features of each plan and the total amount payable are shown again on the payment screen before the order is confirmed. The Publisher may change its prices; any change is notified at least 30 days before it takes effect and applies only from the following renewal, the user remaining free to cancel before that date.

Article 7 — Purchase, payment and seller

Subscriptions are purchased through two distinct channels:

  • On the web — the contract is concluded with the Publisher, who is the seller. Payment is processed by Stripe; the Publisher neither collects nor stores any banking data. The invoice is made available in the subscription management area.
  • In the mobile application — the purchase is made via Apple's App Store or Google's Play Store. The seller is then the app store concerned, and that store's terms of sale, invoicing, cancellation and refund apply, including for any refund request, which must be addressed to it directly.

Article 8 — Term, renewal and cancellation

The subscription runs for the billing cycle chosen and renews automatically at the end of that cycle, for an identical term, until cancelled.

The user may cancel at any time, free of charge and without giving reasons:

  • for a subscription purchased on the web, from the subscription management area in the settings;
  • for a subscription purchased in the mobile application, from the settings of the app store concerned.

Cancellation takes effect at the end of the current period: paid features remain available until that date, no further charge is made, and amounts already paid for the current period are not refunded pro rata, unless the law provides otherwise.

Under Article L215-1 of the French Consumer Code, the Publisher informs the user, no earlier than three months and no later than one month before the end of the current period, of the deadline by which they may object to the tacit renewal of their subscription.

Article 9 — Right of withdrawal

Under Article L221-18 of the French Consumer Code, a consumer user has fourteen days from conclusion of the contract to exercise their right of withdrawal, without giving reasons and without penalty.

However, under Article L221-28(13) of the same Code, that right can no longer be exercised once performance of the service has begun with the user's prior express agreement and the user has expressly waived their right of withdrawal. Immediate access to paid features is offered on that condition, which is stated and collected on the payment screen; absent such agreement, the service is opened only once the fourteen-day period has expired.

To withdraw, the user sends an unambiguous statement to privacy@farygo.com. Refunds are made within fourteen days of receipt of the request, using the same means of payment as the original transaction.

For subscriptions purchased in an app store, the request falls under that store's terms, as seller of the service.

Article 10 — Consumer mediation

Under Article L612-1 of the French Consumer Code, a consumer user may refer a dispute with the Publisher free of charge to a consumer mediator with a view to an amicable settlement, having first attempted to resolve it by a written complaint sent to privacy@farygo.com.

The details of the competent mediator are provided on request to that same address, and appear on this page as soon as they are published.

The user may also use the European online dispute resolution platform: https://ec.europa.eu/consumers/odr.

Article 11 — Personal data

The processing of personal data is described in the [privacy policy](/en/privacy), which forms an integral part of these Terms.

Article 12 — Intellectual property

The Application, its code, its interface, its trade marks, its databases and all of its content are the exclusive property of the Publisher or are licensed to it. Any reproduction, representation, extraction or re-use, in whole or in part, without prior written authorisation is prohibited.

Fare data comes from third-party providers and remains their property; it is made available to the user for personal use only.

The user is granted a personal, non-exclusive and non-transferable right to use the Application for the duration of their registration.

Article 13 — Liability

The Publisher provides the service as is and uses reasonable efforts to ensure its availability and accuracy, without being bound by an obligation of result.

The Publisher cannot be held liable for:

  • variations, errors or unavailability of fares originating from third-party sources;
  • an alert not received, received late, or concerning a fare that has become unavailable;
  • the consequences of a booking made with a third party;
  • an interruption of service due to maintenance, to a provider's failure, or to force majeure.

None of these limitations excludes the Publisher's liability in cases of wilful misconduct, gross negligence or personal injury, nor the statutory guarantees of conformity and against hidden defects, which a consumer user enjoys as of right (Articles L217-3 et seq. of the French Consumer Code, Articles 1641 et seq. of the French Civil Code).

Article 14 — Prohibited use and suspension

The following are prohibited in particular: large-scale automated extraction of the Application's data, resale of the service, creation of multiple accounts in order to circumvent the limits of the free plan, and any attempt to compromise the security or integrity of the service.

In the event of a serious breach of these Terms, the Publisher may suspend or terminate the account after a formal notice that has remained without effect for fifteen days, except where the seriousness of the facts or a security requirement calls for immediate action. Termination on that ground of a subscription in progress gives rise to a refund of the unused portion of the period paid for.

Article 15 — Changes to the Terms

The Publisher may amend these Terms. Any substantial change is notified at least 30 days before it takes effect. A user who refuses the new terms may close their account and, where applicable, cancel their subscription, free of charge, before they come into force.

Article 16 — Governing law and jurisdiction

These Terms are governed by French law.

In the event of a dispute, the parties will seek an amicable settlement, where appropriate through the mediation provided for in Article 10. Failing that, the dispute will be brought before the competent French courts. Under Article 18 of Regulation (EU) No 1215/2012, a consumer retains the right to bring proceedings before the courts of their place of domicile and to rely on the mandatory provisions of the law of their country of residence.
