These General Terms and Conditions of Use (hereinafter the “T&Cs”) define the terms under which Karos, acting on behalf of and for the account of Île-de-France Mobilités, offers a carpooling intermediation service via the Covoit IDFM application to persons acting for non-professional and non-commercial purposes.

These T&Cs apply as of December 1, 2025. It is therefore expressly forbidden for professional drivers such as taxis, VTC or any other type of passenger transport service to use the planned carpooling service offered by Île-de-France Mobilités. If Karos observes a breach of this usage rule, it will immediately suspend the relevant Account, without prejudice to subsequent termination.

Karos provides a service for arranging carpooling. The company connects car drivers with passengers along a predefined commuting route. If registered drivers and passengers are traveling in the same direction, they can share a trip and the associated operating costs.

The term “Application” refers to the Covoit IDFM mobile application published by Île-de-France Mobilités. The term “Site” refers to the website: https://www.iledefrance-mobilites.fr/services-mobilite-alternative/covoiturage.

These T&Cs apply to all content on the Site and the Application (hereinafter collectively the “Interfaces”) as well as to the Service. They govern the legal relationships associated with the use of the Service. The use of the Interfaces and the Service by Members is subject to the acceptance of the T&Cs in force at the time of their registration on the Application. This acceptance is materialized by clicking the validation box “I accept the general terms and conditions of use” in the Application.

Karos does not own, use, deliver, or manage the vehicles offered in the listings. Karos is not the owner of the vehicles and does not itself offer rides through the Application. It does not provide any transportation services and does not act as a transport operator; it merely offers the Application as a means to facilitate carpooling connections.

If the User accesses the Application through a Karos partner (e.g., employer or transport authority) or a custom-branded version, these T&Cs also apply. As stated above, Karos serves only as an intermediary between Users and, with respect to the partner, as a service provider.

Under no circumstances does Karos become a party to any legal relationship — regardless of its nature — between the partner and the Users accessing the Application through the partner’s interface. This includes employment, service, commission, or any other relationships.

Any benefits provided by the partner (e.g., bonuses, special offers, promotions, rewards) are the sole responsibility of the partner. Karos has no influence on and is not party to these agreements, unless Karos has supplied the materials or promotions in question.

You may obtain any information relating to the use of or access to the Service by contacting Karos at one of the email addresses mentioned in the “Contact” section or via the help section available on the Interfaces.

For the purposes of these terms:

Through the Interfaces, the Service enables Members whose usual or announced routes overlap to arrange a shared Trip and for each of them a Journey to be carried out under the terms of the requests suggested via Optimisation (Departure Point, Meeting Point, Drop-off Point, Arrival Point, desired departure time(s), one-time or recurring, etc.), and if applicable, in accordance with the criteria selected by the Member (smoking or non-smoking, pets or no pets, etc.), after mutual validation by the Members involved.

The Service also allows Members to communicate with each other before and, if applicable, after a Trip, to provide reviews, particularly about other Members after a Trip, and to respond to comments on the Interfaces.

The Service may also provide information to Members and publish articles on the Interfaces.

The T&Cs are entered into between the Member and Karos on behalf of and for the account of Île-de-France Mobilités, upon the Member’s express acceptance at the time of registration on the Application, and shall remain in force until terminated by either party under the conditions set out in Article 15 of these T&Cs.

Creating an Account on the Interface under the conditions mentioned in the article below (hereinafter the “Accountˮ) is a prerequisite for the Member to access and/or use the Service.

Once the Application is downloaded and the Account created, and provided the Member is logged into their Account, the Member may access all Service features offered by Karos on the Interfaces, including arranging Journeys and Trips with other Members, interacting with other Members, receiving information, etc.

The equipment (computers, smartphones, tablets, software, telecommunications means, etc.) enabling access to the Interfaces and the Service is the responsibility of the Members, as are any communication costs resulting from their use.

Creating an Account is free of charge for the Member, reserved for individuals aged 18 or older who have full legal capacity, and subject to acceptance of these T&Cs. By registering, the Member confirms that they are at least 18 years old.

Only one Account may be created per email address and phone number. The Service may verify profile information (e.g., phone number, ID document) for reasons of transparency, fraud prevention, or to strengthen trust. However, the Service does not guarantee the accuracy or validity of the verified data. The Service reserves the right to suspend any Account in the event of multiple Accounts being created by the same individual or in the case of a false or impersonated identity. Creating a second account — under one’s own name, another person’s name, or a pseudonym — is strictly prohibited.

After downloading the Application via the relevant app stores, the Member may create an Account by:

The Member undertakes to provide only accurate and truthful information and personal data. In particular, they undertake not to impersonate another person and to promptly inform the Service of any change to the information and personal data (excluding optional fields) provided during registration and, where applicable, to keep them up to date themselves in the profile-management section of the Interfaces. Updates may be made at any time.

By creating an Account, registered Members can publish public carpool offers and contact other registered Members to propose or book a Trip. Listings and public profile information of Members are visible publicly (even to Users without an account), but only registered Members can book or publish Trips.

Account verification may be performed once the Application has been installed by the Member, via the “Verify my account” tab using the email address or phone number provided during registration.

When creating their Account, the Member must choose an email address or, where applicable, a mobile phone number and a password that are unique to them (hereinafter together the “Identifiers”), and must also provide their telephone number. The Identifiers must be sufficiently secure and are transmitted to the Service securely.

The Member’s first name and the initial of their last name (the “Identity”) — excluding their full name — are made public in the Application for the purpose of using the Service.

The Service allows Members to choose any username, provided it complies with the law, these T&Cs, and the rights of other Members. However, the Service encourages Members to use their real identity to facilitate connections between Drivers and Passengers. In all cases, the Service reserves the right to refuse a Member’s registration and/or to require them to change their username.

It is the Member’s responsibility to keep their Identifiers confidential. The Member is solely responsible for the use of their Account and Identifiers. Any use of the Service, connection, or data transmission carried out through their Account using their Identifiers will be deemed to have been made by the Member and under their exclusive responsibility, unless a written and duly justified objection is sent to Karos by registered letter with acknowledgment of receipt to the following address: 10 rue de la Paix, 75002 Paris.

The Service cannot be held liable for the loss of one or more Identifiers and, in the absence of a prior and duly notified written objection to Karos, for any harmful consequences resulting from the use of their Account by an unauthorised person.

The Service, which has no means of verifying the accuracy of the information provided by Members when creating their Account, cannot be held responsible for false statements or identity theft committed by Members.

The Member subscribes to the Service for an indefinite period, starting from the creation of their Account.

They may terminate their subscription at any time, free of charge, by using the unsubscribe feature available on the Platform, under the conditions set out in the article “Termination, suspension and restriction by the Service.”

All Members are personally responsible for complying with local laws, regulations, and obligations relating to their use of the Application.

In particular, Members agree to:

In this respect, the Service intervenes in Journeys only through the suggested Optimization offered to Members, the schedules, or the acceptance of Passengers or Drivers.

To ensure the proper functioning of the Service, Members undertake to: (i) keep their mobile device active and functional; (ii) have an active 3G/4G/5G subscription; and (iii) configure their mobile device so that it regularly shares their geolocation information with the Service.

The Driver undertakes to:

The Passenger undertakes to:

Members can create a Trip listing in the Application by entering information about their planned trip (date, time, departure and arrival locations, number of available seats, option for instant booking, and optional filters).

Listings will be visible to both registered and unregistered Users searching via the Application or a partner website/application. The Service may, at its sole discretion and without notice, choose not to publish or to remove listings that violate these T&Cs or are deemed inappropriate or harmful.

The Service determines the display order and ranking of listings at its sole discretion.

The Application calculates the best meeting point and departure time for the trip. Passengers and Drivers may share the full or part of the route — they do not need the same destination.

As part of the Service, Members are informed via the Interfaces that their recurring routes are used for optimization purposes to organize journeys.

In the case of Optimization, the concerned Members are informed of the “Identity” of other Members likely to be interested in their journey.

Members can edit suggested matches.

The Application provides a system for online seat bookings.

Each Member, acting as Driver or Passenger, has the possibility of making a proposal to another Member suggested by a journey through Optimization. The contacted Member may then accept, edit or reject the proposed Trip. Once the concerned Members have concurrently validated the Trip, the request becomes a validated booking, and Members receive a Booking Confirmation.

The Service shares the phone numbers of the booking parties after confirmation, as explained in the Privacy Policy. It is the responsibility of the Members to fulfill the terms of the agreement.

The Application is primarily for booking seats for private individuals.

Booking a seat for a third-party is strictly forbidden, unless it’s done using that third-party account.

Booking a seat for an unaccompanied animal or for prohibited substances or objects is strictly forbidden.

It is forbidden to publish a listing on behalf of another Member. Each Member must have their own account.

If Members, for a given journey, fail to meet to perform the journey, they may contact each other directly via their mobile device before, during, and after the Trip. To this end, their telephone numbers may be made available to the concerned Member(s).

All Members involved must perform a check-in in the Application at the start of the Trip to validate it.

At the time of departure or when a Member declares having started the journey, the GPS system of the mobile device of each concerned Member automatically activates to allow the Passenger(s) to detect the Driver’s arrival on the map and vice versa, provided this system is activated and available and the Application notifications are allowed on the concerned device.

The location data collected during the Trip period are used by Karos to perform the Verifications. The GPS system of each concerned Member’s mobile device is deactivated at the end of the Trip.

If no proper check-in occurs, no payments will be processed; Drivers won’t be compensated, and Passengers won’t be charged.

The journey is considered completed when the concerned Members have indicated so in the Application. In any case, the journey will be deemed completed two hours after the initially planned arrival time at the Arrival Point set by the Members.

Outside of an Announced Impediment, the journey is deemed validated, and the concerned Members must inform each other directly and/or contest the Trip with Karos within 48 hours following the day of the Trip to request a potential refund by contacting Karos as set out in the “Contact” section of these T&Cs.

At any time before departure, both Members may cancel or modify a booked Trip. In such cases, impacted Members are informed and the Driver receives no cost contribution.

You may rate a Driver if you were a Passenger on their Trip, and vice versa. Ratings include a 1–5-star score and an optional comment. You may not:

The Return Guarantee ensures that, in specific regions, Passengers receive support for an alternative return Trip if their planned carpool falls through.

The Return Guarantee may only be used if all the following conditions are met:

If any of these conditions are not fulfilled, the Member is not entitled to benefit from the Return Guarantee.

The Service’s liability for Trip cancellations or driver no-shows is limited as described in Section 11.

As part of the billing of the Passenger’s share of the Trip Fees and the payment of those Trip Fees to the Driver, the Service performs several verifications.

After the start of the Trip and before the end of it, the Passenger must perform the Check-in Verification in the Application. For this, they have a “VERIFY” button within the Interfaces, which they must press. A green banner informs the Member of the success of the verification.

Server Verification is performed by the Service after the end of the Trip, based on the location data from the Passenger’s and Driver’s mobile devices.

Without the success of the Check-in Verification and the Server Verification, the Passenger will not be charged their share of the Trip Fees, and the Driver will not be credited with the Trip Fees.

Failure to validate this verification may result in the termination of the Account.

As part of our anti-fraud procedures, after the start of the Trip and before its end, Members may receive verification calls to confirm the authenticity of the Trip in accordance with the booking details. Members are required to answer these calls and provide the requested information.

Failure to validate this verification may result in the termination of the Account.

Except for content and data generated by Members, Karos and Île-de-France Mobilités are the exclusive holders of all intellectual-property rights, unless otherwise stated, relating to:

Karos or Île-de-France Mobilités grant Members a non-exclusive, personal, and non-transferable right to use the Application and the Service solely for private and non-commercial purposes. This use must comply with the intended purpose of the Application and the Service.

It is expressly forbidden to:

As part of the use of the Service, Karos, acting on behalf of and for the account of Île-de-France Mobilités, allows Members, when logged into their Account, to interact with each other and to publish content through the Application, such as questions, answers, photographs, reviews, and comments (hereinafter the “Member Content”).

The Member Content belongs to their respective authors. In any event, the Member Content is uploaded or made accessible under the exclusive responsibility of these authors.

To provide the Service effectively, registered Members and Users grant Karos a non-exclusive license to use the content they upload:

Each Member grants Karos an exclusive, royalty-free license to exploit, use, modify, and reproduce, for commercial or non-commercial purposes, the Member Content, provided the content is anonymised. This license is granted worldwide and for the entire duration of protection of the Member Content by applicable copyright law.

Outside of these licenses, the Member content may not be modified, copied, extracted, or disseminated without their prior written authorisation.

The Service reserves the right to suspend temporarily or permanently any Account of a Member or User whose use or behaviour is proven or suspected to be contrary to the T&Cs (hereinafter, “Prohibited Non-Compliant Use”). The responsibility of Karos cannot be engaged as a result of such suspension. In particular, the Service reserves the right not to pay the balance of a Driver if their Account is suspended.

Prohibited Non-Compliant Use includes, but is not limited to:

The Service also reserves the right to temporarily suspend or restrict a Member’s Account if the Member’s Trip patterns — such as frequency, number of passengers, or the amount of the cost contribution — indicate a profit-making intention or fraudulent use.

In serious cases, the Service may immediately terminate the Member’s Account.

In accordance with the provisions of Article 6 of the French Law for Confidence in the Digital Economy (LCEN), Karos acts as a host for content published by Members and made accessible through the Service. Karos is not subject to any general obligation to monitor the information created, transmitted, and/or stored by Members during their use of the Service. In particular, Karos cannot be held responsible for the nature and content posted by Members, including reviews and comments about Members, except in the cases provided for by the LCEN.

Any Member may report to the Service the presence of Prohibited Content on the Interfaces or in connection with the use of the Service.

Each Member undertakes to comply with the applicable French legal provisions in force, in particular—but not limited to—those relating to intellectual-property rights and defamatory or abusive remarks.

The Service reserves the right to promptly remove any content that is proven or suspected to be unlawful or contrary to these T&Cs (hereinafter “Prohibited Content”). Karos cannot be held liable for such removal.

Prohibited Content includes, but is not limited to:

Furthermore, the creation and use by a Member of additional accounts other than the one initially created, under their own identity or that of third parties, without obtaining prior authorisation from the service, is prohibited. Failure to comply with this prohibition may result in the immediate suspension of the Member’s accounts as well as of the entire Service.

Any User or Member who becomes aware of Prohibited Content, proven or suspected, while using the Service must report it without delay, in accordance with Article 6 of the LCEN, by using the contact form available in the Application, indicating:

It is reminded that falsely presenting content or an activity as prohibited, with the intention of obtaining its removal or preventing its distribution, while knowing such information to be inaccurate, is punishable by one year of imprisonment and a fine of €150,000.

As part of the use of the Service by Members, Karos collects and processes certain personal data relating to Members on behalf of and for the account of Île-de-France Mobilités. Karos acts as a processor within the meaning of the GDPR.

By using the Service, Members acknowledge having read the Privacy Policy of the Île-de-France Mobilités Carpooling Service, available at the following address: intercom-help.eu/covoit-idfm-privacy-policy-and-terms-of-use/fr/articles/449495-politique-de-confidentialite.

Karos provides, on behalf of Île-de-France Mobilités, a Service connecting Drivers and Passengers based on compatible recurring routes. It is the responsibility of each Member to verify that the suggested matches meet their needs and to confirm the arrangements for any Trip.

To the fullest extent permitted by applicable law, Karos shall not be liable for:

The Service makes reasonable efforts to ensure that the information provided on the Interfaces is accurate and up to date. The Service reserves the right to correct or update content at any time without prior notice. However, Karos cannot be held responsible for inadvertent errors or for modifications made by unauthorised third parties.

The Service is provided “as is”, and Karos does not guarantee that it will be error-free, uninterrupted, or secure.

In any event, Karos’s total liability towards a User, for any reason whatsoever, shall be expressly limited to the total amount of fees, if any, paid by such User to Karos over the six (6) months preceding the event giving rise to liability.

Nothing in these Terms shall exclude or limit Karos’s liability where it would be unlawful to do so. In particular, Karos does not exclude or limit liability for:

This includes, for Germany, mandatory provisions of the German Product Liability Act (Produkthaftungsgesetz).

These limitations also apply to Karos’s legal representatives, employees, and agents where claims are made directly against them.

Members are solely responsible for maintaining the confidentiality of their access credentials and for ensuring the proper use of their Accounts.

Karos may disclose content when required to comply with applicable laws, legal proceedings, or government requests, or when such disclosure is necessary to protect its rights, interests, those of Members, or the public.

Karos shall endeavour, as far as possible, to ensure Users and Members have permanent access to the Interfaces and to the Service.

The operation of the Interfaces and of the Service may be temporarily interrupted, including in cases of force majeure, scheduled or unscheduled maintenance, updates or technical improvements, emergency repairs to the Interfaces, to evolve their content and/or presentation, or due to circumstances beyond Karos’s control. Karos undertakes to take all reasonable measures to limit such disruptions insofar as they are attributable to it and/or to limit their consequences.

Karos shall in no case be held liable for the unavailability of the Interfaces and/or the Service, their malfunction, inaccessibility, suspension or interruption, or degraded conditions of use, for any reason whatsoever, and cannot be held liable for any direct or indirect damages resulting from these events.

In all cases, and without prejudice to the above and to Article 11, any potential liability held against Karos shall only result in the payment of damages, the amount of which shall be limited to the sums received by Karos.

Karos reserves the right to modify, suspend, or limit access to the Application, its features or services, temporarily or permanently, in whole or in part, at its sole discretion.

Users can obtain assistance via the dedicated help section available on the Interfaces.

The Member provides their bank card number and bank account number in the “Payment Method” tab, allowing them to receive or make a payment when placing an order for a defined Trip. By entering their bank account number, the Member declares that they accept the general terms of use of our banking service provider.

The general terms and conditions of the Payment Partner, accessible here, govern the payment operations carried out by the Member and must be accepted by them. By adhering to these terms, the Member accepts the conditions of Mangopay, which is our Payment Partner. Mangopay S.A. is an electronic-money institution authorised by the Commission de Surveillance du Secteur Financier (CSSF) in Luxembourg and is authorised to provide payment services and issue electronic money.

Drivers may not request advance payments directly from Passengers. The risk of non-payment lies solely with the Driver.

For each Trip, Karos debits the Passenger for their share of the Trip Fees at the time of ordering and transfers payment to the Driver’s account at the end of the Billing Period that includes the Trip.

If a Member carries out Trips as both a Driver and a Passenger during the same Billing Period, Karos may, at its discretion, offset all or part of the amounts payable and receivable. Karos will not transfer to a Driver an amount less than 1 €. If this threshold is not reached during the same Billing Period, the amounts will accumulate over subsequent periods until this threshold is met.

The selected payment method is charged, and the Driver receives their share. The funds in the Money pot belong solely to the Account holder. Transactions are displayed in the Application.

SSL encryption protects payment data.

If an incorrect or unauthorised charge occurs, Members may contact Karos. Members must not initiate chargebacks unless legally justified. Members are liable for chargeback fees if they breach these rules.

The cost contribution is set by the Service. The Service applies income ceilings to prevent misuse. Commercial or profit-making use is strictly prohibited (see Section 5).

In certain cases, the Service may be offered free of charge to Users as part of a Navigo subscription, by their employer, or at the initiative of the other Member.e Membre.

Karos may offer time-limited promotions. The conditions (e.g. duration, pricing) will be announced and published in the Application.

Passengers must use one of the approved MANGOPAY payment methods:

Karos may modify payment options or introduce new systems at any time.

The Service may organise contests with rewards (e.g. gift cards or promo codes). Participation is governed by separate contest terms listed in the Application.

Voucher codes must be entered in “My Voucher Codes” to add their value to your balance.

Karos is not contractually bound to external reward providers and is not responsible for their changes or restrictions.

You may, on a voluntary basis, invite other Members to use the Service via SMS or WhatsApp by using the “Refer a Friend” feature in the Application to send invitations.

Rewards depend on how many successful carpools result from your referrals. Referral bonuses are added to your balance and paid monthly.

Reward amounts are specified in the Application and can be modified at any time.

If the referral link is used too late or not at all, validation is not possible.

As part of national programmes, Members may benefit from carpooling subsidies. The terms of participation are communicated where applicable.

The T&Cs constitute a contract between the Member and Karos, for and on behalf of Île-de-France Mobilités, which either party may terminate, suspend, or restrict at any time.

Karos is authorised to temporarily suspend your Account, restrict your access to the Service, or terminate your contract by operation of law in the event of a breach by the Member of any of their obligations under the T&Cs.

In the event of non-compliance with any provision of the T&Cs by the Member, Karos may, by operation of law, without notice or compensation, and without prejudice to other remedies available to it, suspend the provision of all or part of the Service, including access to the Interfaces, close the Member’s Account, block any new registration request from them, block any payment of the Money pot, and/or terminate the T&Cs.

This exclusion measure is without prejudice to any criminal or civil proceedings to which the Member may be subject by public authorities, third parties, or Karos, in cases where the Member’s behaviour has harmed its interests.

The Member will be informed of the decision by email sent to their most recently provided address and will have the opportunity to respond. After evaluation of the situation, Karos may lift or maintain the measures applied.

Karos reserves the right to restrict access to the Service if such a measure is necessary to resolve or limit IT-security risks or to protect the safety of other Members, Drivers, or Passengers.

Karos reserves the right to refuse the publication of any rating, comment, or question generated by a Member, or to delete them after publication if they violate these T&Cs.

You may terminate your contractual relationship with Karos at any time, free of charge and without providing reasons. To do so, simply press the “Delete Account” button in the Application.

Karos cannot guarantee the payout of the Money pot balance if the Account deletion happens before the monthly payout.

These T&Cs constitute the entire agreement between you and Karos regarding your use of the Applications and the associated Service.

Additional notices, documents, or guidelines provided within the Application may supplement these T&Cs and offer more specific details.

Karos and Île-de-France Mobilités reserve the right to unilaterally amend the T&Cs. In such cases:

If any part of the T&Cs is found to be illegal, invalid, or unenforceable for any reason, the term(s) in question shall be declared non-existent, and the remaining terms shall retain their full force and effect and continue to apply. The non-existent terms shall be replaced by terms that most closely reflect the content of the cancelled clause and the original intent of Karos and Île-de-France Mobilités.

In accordance with applicable legislation, Members have a right of withdrawal of fourteen (14) days starting from subscription to the Service, which is defined as the date the Account is created. If the Member wishes to exercise this right of withdrawal, they must send a written notice to Karos for that purpose. To this end, the Member may use the withdrawal form annexed to these T&Cs or any other unambiguous statement expressing their decision to withdraw. This form must be sent by post or by email to the addresses indicated in the preamble to the T&Cs.

A Member who exercises their right of withdrawal may recover any allowances that have been paid to them into their MangoPay account. Their Account will then be deleted in accordance with the procedures set out in these T&Cs.

Since subscription to the Service is free of charge, no amount will be reimbursed to Members.

The T&Cs are subject to French law.

In the event of a dispute concerning the meaning of a term or provision of the T&Cs, the Member or User may:
(i) contact Karos by registered letter with acknowledgement of receipt at the following address: Karos, 10 rue de la Paix, 75002 Paris, France; or
(ii) seek the assistance of the following French consumer mediator free of charge with a view to reaching an amicable resolution:

(iii) submit complaints regarding the Application or Services via the European Commission’s dispute resolution platform: https://consumer-redress.ec.europa.eu/index_en

Depending on the circumstances, Karos may not be required to participate in dispute resolution proceedings before a consumer arbitration body.

The UN Convention on Contracts for the International Sale of Goods (CISG) does not apply.

If no amicable resolution is reached, the dispute may be brought before the competent courts.

Translations of the T&Cs are provided for information purposes only. The French version shall prevail before the courts.

Karos can be contacted at the following addresses:

Support is available Monday to Saturday from 7:00 a.m. to 8:00 p.m.
