Last updated: May 28, 2026
Application Publisher
The Co-oto application is published by Deniz Ates, a Swiss sole proprietorship, business identification number (IDE) CHE-198.977.309, with registered address at Chemin des Tines 5b, 1260 Nyon, Switzerland. Contact: info@co-oto.app.
1. Acceptance of Terms
Use of the Co-oto application implies complete acceptance of the terms presented.
2. Description of Co-oto
Co-oto is a management tool that allows a vehicle owner to organize sharing their vehicle with people of their choice (drivers). The application enables managing reservations, tracking trips, and calculating and sharing usage costs.
Co-oto is not a matchmaking platform: users already know each other and define the terms of their sharing agreement themselves. Co-oto does not verify user identities and does not intervene in agreements between owners and drivers.
Co-oto does not process any payments and does not intervene in any money transfer between users. The cost calculations, expense splits and balances displayed by the application are provided for informational purposes only, based on the data entered by users. It is the responsibility of each user to verify these calculations and personally validate any money transfer to other members, by the means of their choice. Co-oto cannot be held liable for an erroneous transfer, a missed payment or a financial dispute between users.
Co-oto is not a transport company, nor a public transport service.
3. Responsible Use
The application must be used legally and responsibly. Use while driving is strictly prohibited; all operations must be performed while stationary.
4. Disclaimer
Co-oto cannot be held liable for accidents, damage, theft, fines, or violations occurring during shared vehicle use. Liability rests with:
- The driver at the time of the incident for accidents they cause
- The owner for vehicle defects (maintenance, technical inspection)
Users must settle liability and compensation matters between themselves. Adequate insurance is strongly recommended.
5. User Responsibility
The user is solely responsible for compliance with applicable laws and regulations.
6. Vehicle Owner Obligations
The vehicle owner agrees to:
- Have car insurance that covers lending the vehicle to third parties
- Ensure their insurance policy permits lending the vehicle
- Verify that invited drivers hold a valid driving license for the vehicle category
- Clearly define vehicle usage conditions with their drivers
- Maintain the vehicle in good working condition with up-to-date technical inspection
7. Driver Obligations
The driver agrees to:
- Hold a valid driving license for the borrowed vehicle category
- Comply with traffic laws and usage conditions defined by the owner
- Report any incident, damage, or violation that occurs during use
- Return the vehicle in the condition it was received
- Accurately enter trip information (mileage, fuel)
8. Insurance
Co-oto does not provide any insurance. It is the owner's responsibility to verify that their car insurance policy covers lending the vehicle to identified third parties.
Some insurers require prior declaration or offer specific extensions for private car sharing. Co-oto strongly recommends that owners contact their insurer before sharing their vehicle.
Drivers should also verify their own coverage in case of damage caused to a borrowed vehicle.
9. Legal Compliance
Co-oto is a management tool. Each user is responsible for ensuring their vehicle use (cost sharing, lending, or other) complies with laws in their jurisdiction, particularly regarding:
- Car insurance
- Taxation (declaration of any income)
- Authorization to conduct rental activities, if applicable
Co-oto is not responsible for users' failure to comply with these obligations.
10. Fines and Violations
In case of a traffic violation committed during vehicle use by a driver, the driver assumes full financial and legal responsibility.
The owner may use application data (trip history, reservations) to identify the responsible driver at the time of the violation and transmit this information to competent authorities if necessary.
11. Release of Liability
The user acknowledges using Co-oto at their own risk. Under no circumstances shall Co-oto, its developers, or representatives be held liable for direct or indirect damages resulting from:
- Use of the application
- Vehicle sharing organized through it
- Inaccuracy of information entered by users
- Conflicts between users
12. Malfunctions and Unavailability
Co-oto is provided "as is". The developers cannot guarantee an uninterrupted or error-free service and shall not be held liable for malfunctions or temporary unavailability.
The user agrees to report to Co-oto, without delay after discovery, by email to info@co-oto.app, any defect, malfunction, calculation error or abnormal behaviour of the application they observe. By analogy with art. 201 of the Swiss Code of Obligations, in the absence of immediate notice, the user shall be deemed to have accepted the service as-is for apparent defects, to the extent permitted by applicable law. This obligation does not affect the mandatory rights granted to consumers by the law of their country of residence.
13. Modification of Terms
Co-oto may modify these terms at any time. Users will be notified of changes through the means provided in article 32. Minor modifications (wording, link updates, clarifications without effect on the rights and obligations of the parties) take effect upon publication. Substantial modifications, which affect users' rights or obligations, take effect after a reasonable notice period of at least 30 days following notification. Users who do not accept the new terms may terminate their account free of charge before the new terms take effect; failing termination within this period, they shall be deemed to have accepted the modifications. Continued use of the application after the modifications take effect constitutes acceptance.
14. Applicable Law
These terms are governed by Swiss law. In case of dispute, Swiss courts (Canton of Vaud) shall have sole jurisdiction. This clause does not affect the mandatory consumer protection rights granted by the legislation of the user's country of residence.
These terms are drafted in French and translated into several languages for convenience. In case of divergent interpretation between versions, the French version alone shall prevail.
15. Data Use
Data is stored in a secure database. It is not sold to third parties without explicit consent. For more details, see our privacy policy.
16. Data Deletion
Data from users inactive for more than 12 months may be deleted after prior notice.
17. Free Version Limits
The free version of Co-oto allows use of the application with certain feature and usage limits. These limits are published on the Pricing page and may evolve. Any change to the free version limits will be communicated to affected users in accordance with article 32.
18. Subscriptions
Paid subscriptions unlock additional features detailed on the Pricing page. They auto-renew and may be cancelled at any time via the store settings (App Store or Google Play); cancellation takes effect at the end of the current billing cycle.
Free access to the Plus plan may also be granted as part of a partnership with a public authority. Specific terms are described in article 35.
Right of withdrawal for European consumers: in accordance with Directive 2011/83/EU, consumers residing in the European Union are in principle entitled to a 14-day withdrawal period from the subscription date. By subscribing to a paid plan and immediately accessing the corresponding features, the user expressly acknowledges and accepts that performance of the service begins before the end of the withdrawal period and waives their right of withdrawal, the digital service being then considered fully performed. This waiver does not affect the refund rights handled by the stores as described in article 19.
19. Refunds
iOS – App Store (Apple)
For iOS (App Store), refunds go exclusively through Apple.
Android – Google Play
For Android (Google Play), the developer may grant refunds in case of proven bugs.
20. Minimum Age
Use of Co-oto is reserved for adults (18 years minimum). Vehicle owners must only invite adult drivers with a valid driving license.
21. Data Accuracy
The user guarantees the accuracy of information entered in the application, including mileage, fuel costs, and reservations. Co-oto does not verify this data and is not responsible for input errors.
22. Account Termination and Suspension
Termination by the user: the user may delete their account at any time and without cause, from the application settings or by contacting info@co-oto.app. Deletion automatically terminates any subscriptions managed directly by Co-oto; subscriptions managed via the stores must be cancelled separately by the user from their App Store or Google Play account. Upon deletion, the user's personal data is erased under the conditions provided by the privacy policy, subject to data that Co-oto is legally required to retain (particularly for accounting and tax obligations).
Suspension or deletion by Co-oto: Co-oto reserves the right to suspend or delete any user account in case of:
- Violation of these terms of use
- Fraudulent or abusive use of the application
- Reports from other users
The user will be notified of the suspension with reasons given and may contact support at info@co-oto.app to contest this decision within 30 days.
23. Intellectual Property
The Co-oto application, its name, logo, and all content are protected by intellectual property rights. Any unauthorized reproduction, modification, or use is prohibited.
24. Severability
If any clause of these terms of use is declared null or unenforceable, the other clauses shall remain in full force and effect.
25. User Indemnification
The user agrees to defend, indemnify and hold harmless Co-oto, its developers and representatives, against any claim, demand, damage, cost or expense (including reasonable legal fees) resulting from: their use of the application, vehicle sharing organized through it, a violation of these terms, or an infringement of the rights of a third party.
26. No Financial, Tax or Legal Advice
Co-oto is a management and tracking tool. The cost calculations, expense sharing and statistics provided by the application are for informational purposes only. They do not constitute financial, tax, legal or insurance advice in any way. The user remains solely responsible for their tax declarations, legal obligations and financial decisions.
Records of trips, reservations, expenses and calculations in the application have indicative value only and do not constitute formal evidence enforceable against third parties (tax authorities, public authorities, insurance companies, courts). Any use of this data as evidence is the responsibility of the user and requires, where applicable, validation by the other parties concerned.
27. Force Majeure
Co-oto shall not be held liable for any delay or failure in the performance of its obligations resulting from circumstances beyond its control, including but not limited to: cloud infrastructure or third-party service outages, natural disasters, pandemics, acts of war or terrorism, governmental or regulatory decisions, or any other cause of force majeure.
28. Third-Party Services
Co-oto uses third-party services for its operation (including Google Firebase, Apple App Store, Google Play Store and RevenueCat). Co-oto does not guarantee the availability, security or continuity of these services and shall not be held liable for interruptions, modifications or discontinuations decided by these providers. The use of these services is subject to their own terms of use.
29. Termination of Service
Co-oto reserves the right to interrupt or permanently discontinue the service, in whole or in part, with reasonable notice of 30 days communicated to users. In case of discontinuation, users will be able to export their data during the notice period. Active subscriptions will not be renewed and no refund will be due for the remaining period of the current cycle.
30. Assignment of Rights
Co-oto may assign, transfer or delegate all or part of its rights and obligations under these terms to a third party, particularly in the event of a merger, acquisition or asset sale, without requiring the user's prior consent. The user will be informed of any assignment. The user may not assign their rights without the prior written consent of Co-oto.
31. Prohibited Uses
The user agrees not to:
- Attempt to decompile, disassemble or reverse engineer the application
- Access the application through automated means (bots, scripts, scraping)
- Circumvent the technical limitations of the application or subscription
- Use the application for commercial vehicle rental purposes without informing Co-oto
- Impersonate another user or provide false identification information
32. Notification Methods
Any notification relating to these terms (including modifications, account suspensions or service termination) will be communicated through at least one of the following means: in-app notification, push notification or email sent to the address associated with the user's account. The user is responsible for maintaining a valid and up-to-date email address.
33. Amicable Resolution
In the event of a dispute relating to the use of Co-oto or the interpretation of these terms, the parties agree to seek an amicable solution before any legal action. The user will contact Co-oto by email at info@co-oto.app. Co-oto undertakes to respond within 30 days. Failing amicable resolution within 60 days, the parties may refer the matter to the competent courts.
34. Non-Commercial Use and Cost Sharing
Co-oto is designed for vehicle sharing between individuals in a private context (family, friends, neighbours, colleagues) or for fleet management within an organisation. The application aims to facilitate the sharing of actual vehicle usage costs (fuel, insurance, maintenance, depreciation), and not to generate a profit.
The user shall not use Co-oto to conduct a for-profit vehicle rental business, unless they hold the authorisations, licences and insurance required by the legislation of their jurisdiction. In many countries, commercial vehicle rental is a regulated activity that requires, among other things: professional registration, specific insurance covering rental to third parties, collection and remittance of VAT, and compliance with applicable safety standards.
Co-oto does not verify the nature of transactions between users and disclaims any liability in the event of use of the application for commercial purposes that do not comply with applicable regulations. The user who conducts commercial activity through the application assumes full legal, tax and insurance responsibility.
35. Plus access through a partnership with a public authority
35.1 Description of the partnership
Co-oto offers public authorities (notably municipalities, but also cantons, inter-municipal bodies or metropolitan areas) a flat-rate plan that gives their residents free access to Co-oto Plus for the entire duration of the plan. The public authority pays the flat-rate fee to Co-oto; Co-oto remains the sole provider of the service to end users and the sole controller of their data within the application.
35.2 Eligibility
Access to the Plus plan via partnership is reserved for adult individuals (see article 20) holding an active Co-oto account and actually residing in the partner public authority's territory on the activation date. A single user may benefit from Plus access through only one partner public authority at a time.
35.3 Activation and verification
To activate access, the resident must cumulatively:
- enter in the application the activation code provided by their public authority;
- authorise a one-time location check via the geolocation services of their device, in order to confirm their presence within the public authority's territory at the moment of activation;
- tick the following sworn declaration: "I certify that I am a resident of [name of the public authority] and I understand that fraudulent use may result in the immediate withdrawal of access and the retroactive billing of the subscription."
Activation is final for the duration of the plan. Co-oto does not perform further periodic geographic checks.
35.4 Processing of verification data
The geographic position recorded at activation is used solely to validate eligibility for the partnership. Co-oto only retains the verification result (validated or not validated), the partner public authority identifier and the activation date; the raw coordinates are not stored beyond the time required for the verification. The detail of purposes, legal bases, retention periods and user rights appears in the privacy policy.
35.5 Duration and end of the partnership
Plus access granted through a partnership is tied to the validity of the plan subscribed by the public authority. In the event of non-renewal, Co-oto will notify affected users at least 30 days before the expiry date, through the means set out in article 32. On that date, Plus access is deactivated and the user automatically reverts to the free version, without any charge, renewal or loss of previously entered data. The user retains the option of taking out a personal Plus subscription under the conditions of article 18.
35.6 Fraudulent use and sanctions
The following uses are considered fraudulent, among others:
- entering the activation code while not being a resident of the partner public authority;
- sharing, reselling or disseminating the code to ineligible third parties;
- providing a false sworn declaration of residence;
- circumventing, by any means whatsoever, the geographic check at activation (including the use of a VPN, location-spoofing software or a third-party device).
In case of established fraudulent use, Co-oto reserves the right to immediately withdraw Plus access and to retroactively bill the user the standard Plus tariff in force, multiplied by the number of started months of fraudulent use, without prejudice to any civil or criminal proceedings and the other measures provided in articles 22 (account suspension) and 25 (indemnification).
35.7 Role of the partner public authority
The partner public authority acts as funder and communication relay. It receives no personal information about residents who activate the code and has access neither to trips nor to individual usage data. Only aggregated adoption statistics (for example the total number of activations) may be shared with it. The public authority is neither a party to the contract between the user and Co-oto, nor responsible for the operation of the application, which remains exclusively provided by the publisher mentioned at the top of these terms.
