Terms of Use and Terms of Sale — Yamo
Version 1.0 — effective as of 27 August 2026 LANGUAGE NOTICE. This English version is a courtesy translation provided for convenience only. The binding version of this agreement is the French original (« Conditions Générales d'Utilisation et de Vente »). In the event of any discrepancy or difficulty of interpretation, the French version prevails (see Article 19.5), without depriving consumers of the mandatory protections of the law of their country of habitual residence. Each article opens with an "In short" box written in plain language. These boxes are part of the agreement. In the event of any contradiction between a box and the detailed text of the article, the detailed text prevails.
Legal notice
Publisher: YOMA STUDIO, a French simplified joint-stock company (société par actions simplifiée) with a share capital of EUR 1,245.50, registered with the Évry Trade and Companies Register (RCS) under number 939 664 660 (SIRET 939 664 660 00031; EUID FR7801.939664660), with its registered office at 3 Rue Jules Guesde, 91130 Ris-Orangis, France. Intra-Community VAT number: FR71939664660 (hereinafter "we" or "us"). Publication director: Emmanuel Costa, Chief Executive Officer. Contact: support-app@yamochat.com, or by post to YOMA STUDIO, 3 Rue Jules Guesde, 91130 Ris-Orangis, France. Hosting provider: Amazon Web Services EMEA SARL, 38 Avenue John F. Kennedy, L-1855 Luxembourg — data hosted in the European Union (eu-west-1 region, Ireland). This document also constitutes the legal notice (mentions légales) of the Yamo application.
PART 1 — Article 1: What the application does
In short: Yamo lets you chat with artificial intelligences. For each question, we automatically select the most suitable AI model, including models operated by third-party providers. 1.1. Yamo (the "Application") is a service for conversing with artificial intelligence systems (the "Service"). When you send a message (an "Input"), the Application automatically selects the most suitable AI model to answer it and transmits your message to that model. The generated answer constitutes an "Output". 1.2. Some models are operated by us, others by third-party providers (the "Model Providers"). The up-to-date list of Model Providers is available at any time at https://yamochat.com/models and in our Privacy Policy. This list may change over time; so may the way automatic selection works. 1.3. You are interacting with artificial intelligences, not with human beings. Outputs are artificially generated content.
Article 2: Acceptance and amendment of the Terms
In short: Before first use, you must scroll through this entire text, then confirm that you have read and accept it. Without this confirmation, the Application cannot be used. If we make a significant change to the agreement, we will notify you 30 days in advance. If you refuse, you can leave, and be refunded pro rata if you pay for a subscription. 2.1. Mandatory acceptance before use. Access to the Service is subject to prior acceptance of these Terms. On first use, the confirmation button ("I have read and accept the Terms") only becomes active after you have scrolled through this entire text. By confirming, you certify that you have read, understood and accepted these Terms in full. Until this confirmation has taken place, the Service is not accessible. The complete scroll, the timestamp and your acceptance are recorded (Article 19.1). The version in force remains available at any time in the Application (Settings → Terms of Use) and at https://yamochat.com/terms. 2.2. Amendments. We may update these Terms. In the event of a substantial change, you will be informed at least 30 days before it takes effect, by in-app notification or by email, and you will be asked to accept the new version in accordance with Article 2.1. If you do not accept the change, you may stop using the Service and, where applicable, cancel your Subscription; the amounts corresponding to the unused period will then be refunded to you pro rata.
Article 3: Adults only, account
In short: By using Yamo, you warrant that you are an adult (18 or over). You can try the app without an account (guest mode). To create an account, all you need is an email address or a phone number, verified by a code. 3.1. Adult status. By accessing the Service and accepting these Terms, you represent and warrant that you are an adult, meaning 18 years of age or older (or the applicable age of majority in your country of residence if higher). The Service is not intended for minors. If we become aware that an account is being used by a minor, we may suspend or delete it and erase the associated data as described in the Privacy Policy. 3.2. Guest mode. The Application may be tried without creating an account, with limited features. These Terms apply from the very first use, including in guest mode, in particular the adult-status warranty (Article 3.1) and prior acceptance (Article 2.1). 3.3. Account. Creating an account is necessary to keep your conversation history across several devices and to take out a Subscription. It requires a valid email address or a valid mobile phone number, verified by a one-time code. You undertake to provide accurate information and to keep it up to date. Your account is personal; you are responsible for keeping your access credentials confidential and for the activities carried out from your account, except in the event of fraudulent use not attributable to you. 3.4. You may delete your account at any time from the Application (Settings → Account → Delete my account). Deletion results in the erasure of your conversations as described in the Privacy Policy.
Article 4: Free Version and advertising
In short: The free version is funded by non-targeted advertising: ads are never chosen based on the content of your conversations or on a profile about you. It is also limited by a usage allowance: a gauge in the settings shows where you stand. 4.1. The "Free Version" gives access to the Service within a free usage allowance, determined by the number of messages you send. This allowance is displayed in the Application: a gauge shows you in real time how much you have used and how much remains (Settings → Usage). The applicable allowance is the one shown in the Application at the time of use; it may be adjusted over time. In the event of a significant reduction, you will be informed in the Application. 4.2. The Free Version includes the display of advertising. These ads are non-targeted: they are never selected based on the content of your conversations, nor on the basis of an individual advertising profile. They may only take into account generic elements such as the Application language or the store country. The exact arrangements are described in the Privacy Policy. 4.3. We do not sell your conversations, we do not show them to advertisers and we do not use them for targeted advertising. This commitment applies to all versions of the Service.
Article 5: Important warnings about AI
In short: AI can be wrong, including in a convincing way. Its answers are not medical, legal or financial advice. In an emergency, call the emergency services (112), not an AI. Verify any important information before relying on it. 5.1. Outputs may be inaccurate. AI models produce text through statistical computation: they may generate information that is wrong, incomplete, outdated or made up (a phenomenon known as "hallucination"), including on important subjects, and present that information convincingly. You must independently verify any important information before using it or making a decision based on it. 5.2. Not professional advice. Outputs are provided for general information purposes. They do not constitute and do not replace medical, legal, financial, tax or any other personalised professional advice. Consult a qualified professional for any decision of that nature. 5.3. Emergencies. The Service is not designed for emergency situations. If you are in danger or in distress, immediately contact the emergency services (112 in the European Union; in France: 15 for the SAMU, 3114 for suicide prevention, free of charge, 24/7). 5.4. Your decisions remain your own. You are solely responsible for how you use the Outputs and for the decisions you make.
Article 6: Rules of use
In short: Use the app normally and lawfully. Prohibited: illegal content, hacking or circumvention attempts, mass data extraction, reselling the service, lending your account (in particular to a minor). You can report a problematic answer directly in the app. 6.1. You undertake not to: — use the Service for illegal purposes, or to create, obtain or distribute unlawful content (in particular: content involving minors, incitement to hatred or violence, assistance in committing offences); — attempt to circumvent the Service's security measures, usage limits or filters, or interfere with its operation; — extract data or Outputs in an automated or massive way (scraping), or use the Service to build a competing service; — resell, sublicense or share access to the Service, or make manifestly excessive or abusive use of it inconsistent with normal personal use; — impersonate a third party, or allow your account to be used by a third party, in particular by a minor. 6.2. Reporting. A "Report" feature is available in the Application to alert us to any Output you consider shocking, dangerous or unlawful. We review reports and improve our filters accordingly. 6.3. In the event of a breach of these rules, we may suspend or restrict your access under the conditions of Article 15. We cooperate with the competent authorities as provided by law.
Article 7: Your content, our rights, the Outputs
In short: Your messages remain yours. You only authorise us to process them to answer you and to produce anonymous trend statistics (which you can turn off in the settings). The AI's answers are yours to use as you wish, at your own risk. The app itself belongs to us. 7.1. Your Inputs. You retain all your rights in your Inputs. You grant us a limited, worldwide, non-exclusive licence to host, transmit and process your Inputs for the sole purposes of: (a) providing the Service, including transmission to the Model Providers to generate the Outputs; and (b) producing aggregated and anonymised usage-trend statistics, as described in the Privacy Policy. You can turn off purpose (b) at any time (Settings → Privacy). We never publish extracts from your conversations. 7.2. The Model Providers process your Inputs solely to generate the Outputs, in accordance with their own terms and our agreements with them. Each Model Provider's commitments, in particular regarding any use of Inputs to train its models, are detailed in the Privacy Policy and on the "Our models" page (https://yamochat.com/models). We will inform you of any significant change to these commitments as provided in Article 2.2. 7.3. The Outputs. We claim no rights in the Outputs generated from your Inputs. You may use them freely, under your own responsibility (see Article 5). Given the nature of AI, identical or similar Outputs may be generated for other users; we guarantee neither their originality nor their protection by any intellectual property right. You are responsible for checking that your use of the Outputs does not infringe the rights of third parties. 7.4. The Application. The Application, its trademarks, logos, interfaces, software and databases are our property or that of our licensors. These Terms grant you only a personal, non-exclusive and non-transferable right to use the Service.
Article 8: Personal data
In short: The details of how your data is processed are in the Privacy Policy, available in the settings. For the essentials on advertising, see Article 4; on the use of your messages, Article 7. 8.1. We process your personal data in accordance with our Privacy Policy, available in the Application and at https://yamochat.com/privacy. It describes in particular: the data processed, the purposes, the recipients (including the Model Providers, identified by name), the retention periods, your rights and how to exercise them. 8.2. Conversations relating to sensitive subjects (in particular health, political or religious opinions, sex life) are automatically excluded from the statistics, as described in the Privacy Policy.
PART 2 — Article 9: Content and price of the Subscription
In short: Premium = no advertising + extended usage. The plans, their content, duration and price including VAT are displayed in the app and in your Store at the time of subscription. 9.1. The "Premium Subscription" gives access, for its duration, to extended use of the Service, without advertising. One or more plans may be offered. The exact content of each plan (in particular usage limits and accessible models) is described in the Application at the time of subscription. 9.2. The Subscription is taken out from the Application, through your Apple App Store or Google Play account (the "Stores"). The price, duration (for example monthly or annual) and features of the chosen plan are those displayed in the Application and in the Store at the time of subscription; prices are shown inclusive of VAT. Payment is processed by the Store under its own terms. 9.3. A free trial or promotional price may be offered to new subscribers. Its duration and conditions are stated at the time of subscription. Unless cancelled before the end of the trial, the paid Subscription starts automatically when the trial ends, at the price displayed at the time of subscription.
Article 10: Duration, renewal, cancellation of the Subscription
In short: The subscription renews automatically. You can turn off renewal at any time, in a couple of taps, in your App Store / Google Play settings; you keep Premium until the end of the period you have already paid for. 10.1. The Subscription is entered into for the duration stated at the time of subscription and renews automatically for identical periods, unless cancelled. 10.2. You may cancel renewal at any time, free of charge and without giving any reason, directly from your Store's subscription settings (Apple: Settings → your name → Subscriptions; Google: Play Store → Profile → Payments and subscriptions). Cancellation takes effect at the end of the current, already-paid period, during which you keep the Premium benefits. A reminder of how to cancel is available in the Application (Settings → Subscription). 10.3. You will be informed of renewal deadlines as required by the applicable regulations and by the Stores. 10.4. Price changes. If the price of the Subscription increases, you will be informed at least 30 days before the increase applies to your renewal, with the option to cancel before it takes effect. An increase never applies to a period already paid for.
Article 11: Right of withdrawal
In short: You have 14 days to change your mind after subscribing. Because the service starts right away, if you withdraw you only pay for the days used. The simplest route: request a refund through Apple or Google. 11.1. In accordance with the French Consumer Code, you have 14 days from taking out the Subscription to exercise your right of withdrawal, without having to give any reason. 11.2. By subscribing, you expressly request that the provision of the Premium Service begin immediately, without waiting for the end of the withdrawal period. If you exercise your right of withdrawal after this performance has begun, you will be refunded the price paid, less an amount proportional to the service already provided between the subscription and the communication of your decision. 11.3. To exercise this right, you may: (a) use your Store's refund procedure (Apple: "Report a Problem" at reportaproblem.apple.com; Google: Play Store → order history), which is the fastest route; or (b) notify us of your decision at support-app@yamochat.com, for example using the model form appended to these Terms. The refund is made no later than 14 days after receipt of your decision, using the payment method you used.
Article 12: Legal guarantee of conformity
In short: The law guarantees that the paid service works as promised. If it does not and we do not fix it, you can obtain a price reduction or a refund. (Note: "AI can be wrong" is part of the normal description of the service, see Article 5.) LEGAL GUARANTEE OF CONFORMITY Consumers benefit from the legal guarantee of conformity provided for in Articles L.224-25-12 et seq. of the French Consumer Code for digital content and digital services. On this basis, we are liable for the conformity of the Premium Service with its description throughout the duration of the Subscription. In the event of a lack of conformity, you may require it to be brought into conformity free of charge; failing that, you may obtain a price reduction or the termination of the contract, under the conditions laid down by the French Consumer Code. These rights are exercised without prejudice to the right of withdrawal (Article 11) and are independent of any commercial warranty. 12.1. The conformity of the Service is assessed against its description in these Terms, which expressly includes the probabilistic nature of the Outputs described in Article 5: the fact that an answer from an AI model is inaccurate does not, in itself, constitute a lack of conformity of the Service. 12.2. For any claim under the guarantee: support-app@yamochat.com.
PART 3 — Article 13: Availability and evolution of the Service
In short: We aim for a permanently available service, without being able to guarantee 100% availability (maintenance, outages, third-party providers). The available AI models change over time. 13.1. We use reasonable means to ensure the availability of the Service, without guaranteeing uninterrupted availability. Access may be temporarily suspended for maintenance, updates, or due to external circumstances (in particular the unavailability of a Model Provider or of the network). 13.2. The Service evolves continuously: we may add, modify or remove features and models, provided this does not substantially degrade the Service as described at the time of your subscription. In the event of a substantial change unfavourable to Premium subscribers, Article 2.2 applies.
Article 14: Liability
In short: We are responsible for making the service work properly. We are not responsible for the decisions you make based on the AI's answers, nor for damage caused by misuse of the app. Nothing in this agreement reduces your statutory consumer rights. 14.1. We are liable for direct damage caused by a proven breach of our contractual obligations, under the conditions of the applicable law. 14.2. To the extent permitted by law, we are not liable for: (a) damage resulting from the use of the Outputs or from decisions made on the basis of them, provided the warnings in Article 5 were brought to your attention; (b) damage resulting from use of the Service that does not comply with these Terms; (c) the content of third-party sites or services to which an Output may refer. 14.3. Nothing in these Terms excludes or limits our liability in the event of wilful misconduct, gross negligence, personal injury, or in any other case where the law prohibits such a limitation. Nothing in these Terms deprives consumers of the mandatory rights they hold under the law.
Article 15: Suspension and termination
In short: If you break the rules, we can suspend your account, after notifying you and letting you respond, except in serious cases. We can also stop the service at any time through no fault of yours: if you are a subscriber and the shutdown happens without 30 days' notice, we refund the current period in full. 15.1. In the event of a breach of these Terms, we may suspend or restrict your access to the Service after informing you and giving you the opportunity to present your observations. In the event of a serious or repeated breach (in particular Articles 3.1 and 6.1), suspension or termination may be immediate. 15.2. We may stop providing all or part of the Service or terminate your account, through no fault of yours, at any time: (a) for the Free Version, with prior notice in the Application where possible; (b) for Premium subscribers, either with at least 30 days' notice, in which case the amounts paid for the unused Subscription period are refunded pro rata, or with immediate effect or shorter notice, in which case all amounts paid for the current Subscription period are refunded in full. We may also suspend or stop the Service immediately where required by law or for imperative security reasons. 15.3. You may stop using the Service and delete your account at any time (Article 3.4). Deleting your account does not by itself end the renewal of the Subscription, which must be cancelled through the Store (Article 10.2).
Article 16: Force majeure
16.1. Neither party shall be held liable for a failure caused by a force majeure event within the meaning of Article 1218 of the French Civil Code and the related case law.
Article 17: Complaints and consumer mediation
In short: A problem? Write to us first, we answer quickly. If you are not satisfied with our answer, you can refer the matter, free of charge, to an independent mediator. This is an option: you can also go directly to court. 17.1. For any complaint, contact us at support-app@yamochat.com or by post (YOMA STUDIO, 3 Rue Jules Guesde, 91130 Ris-Orangis, France). We acknowledge receipt and use our best efforts to respond within 10 working days. 17.2. Mediation. In the event of a dispute between a user acting for non-professional purposes and us, each party will first endeavour to resolve it amicably. Failing agreement, and in accordance with Articles L.612-1 et seq. of the French Consumer Code, if your written complaint has not been resolved within two months, you may refer the matter, free of charge, to the consumer mediator to which we belong: CM2C, Centre de la médiation de la consommation de conciliateurs de justice. This service is reserved for consumers within the meaning of the applicable legislation. You may refer the matter: — through the referral form available on its website: www.cm2c.net; — by post to: CM2C, 14 rue Saint-Jean, 75017 Paris, France. The applicant must state the subject of the dispute to the mediator and send it all the supporting documents, as indicated in the referral form; otherwise, the referral cannot be taken into account. The mediator may be contacted within one year of your written complaint to us. The outcome of the mediation is in principle reached within ninety (90) days from the date on which the mediator has all the elements on which the request is based, unless extended in the case of a complex dispute, in accordance with Article R.612-5 of the French Consumer Code. If the solution proposed by the mediator does not satisfy either party, each may bring the matter before the competent court under the conditions of Article 18. Recourse to mediation is an option, and not a mandatory prerequisite to going to court; each party may withdraw from the mediation process at any time. 17.3. Where the user acts for professional purposes or is a legal entity, the mediation procedure described above does not apply.
Article 18: Governing law and jurisdiction
In short: This agreement is governed by French law. If you live in another EU country, you keep the mandatory protections of your country and can bring proceedings before your local courts. 18.1. These Terms are governed by French law, without depriving consumers habitually residing in another State of the protection afforded to them by the mandatory provisions of the law of that State. 18.2. Any dispute relating to these Terms may be brought, at the consumer's choice, before the courts of their place of residence or those of our registered office, under the conditions provided for by the applicable law.
Article 19: Miscellaneous
19.1. Evidence. Unless proven otherwise, the Service's technical records and logs constitute evidence of the operations carried out, in particular the complete scroll, the timestamp and the acceptance of the Terms (Article 2.1), the settings and the reports. 19.2. Severability. If any provision of these Terms is held to be void or unenforceable, the other provisions remain in force. 19.3. No waiver. Failure to rely on a breach does not constitute a waiver of the right to rely on it later. 19.4. Assignment. We may transfer this agreement to an entity succeeding us in the operation of the Service, with prior notice and without any reduction of your rights or guarantees. 19.5. Language. These Terms are drafted in French. Translations, including this English version, may be made available for ease of reading. In the event of any discrepancy or difficulty of interpretation, the French version prevails, without depriving consumers of the mandatory protections of the law of their country of habitual residence.
