Terms and Conditions of Sale

Version in force as of 2026-10-18.

1. Purpose

These terms govern the subscription, provision and payment of subscriptions to the Koaee services, published by Ubnbee LLC, a company incorporated under the laws of the State of Delaware (United States), whose full details appear in the legal notice.

They apply to any order placed on koaee.ai, to the exclusion of any other document. Subscribing to a plan constitutes full and unreserved acceptance of these terms.

2. Client status

The services are intended for professional use. The client declares that they are subscribing for the purposes of their professional activity and have the legal capacity to enter into a contract.

The services are not currently offered to individuals or entities established or resident in the State of Delaware (United States). The client declares at the time of order that they are not established or resident there. An order placed contrary to this declaration may be cancelled by Ubnbee LLC, in which case any amounts already paid will be refunded.

3. Contractual documents

The relationship is governed, in decreasing order of precedence, by: the signed purchase order or quote where one exists; the personal data processing agreement; these terms and conditions of sale; the terms of use; the privacy policy. In the event of any conflict, the higher-ranking document prevails, in respect of the specific provision concerned only.

4. Formation of the contract

The order is placed online. The client selects a plan and a billing frequency, then confirms payment. The contract is formed upon confirmation of the order, evidenced by a confirmation email containing the summary.

Before confirming, the client may review the details of their order and correct any errors.

5. Description of the plans

Each plan grants the right to use the Koaee conversational assistants up to a defined number of monthly conversations, with the features described in the pricing table published on the homepage on the day of subscription.

A conversation means an exchange session between an end user and the assistant, regardless of the number of messages.

A showcase website option can be added to the subscription, at a price of 59 € per month or 566 € per year. It follows the billing frequency of the main subscription.

The features listed in the pricing table are those actually available. Features announced as upcoming do not fall within the contractual scope until they are delivered, and their absence constitutes neither a breach nor grounds for a refund.

6. Pricing

Prices are stated in euros, excluding any applicable taxes. The applicable price is the one displayed in the pricing table published on the homepage at the time of subscription.

Promotional rate. The Essential plan benefits from a promotional rate of €39 per month instead of €49, until 31 December 2026. This rate is secured for the duration of the subscription taken out during the promotional period; it does not automatically apply to subsequent renewals, of which the customer is informed in accordance with Article 17.

Annual rate. Annual payment entitles the client to a discount compared with the total of twelve monthly payments. In return, it entails a twelve-month commitment (article 8).

7. Overage

The number of conversations included in each plan is set out in the pricing table. It is assessed per billing period, with no carry-over of unused conversations from one period to the next.

When ordering, and at any time thereafter from their client area, the customer chooses between two options: no overage, the option applied by default, and billed overage. Any change of option takes effect immediately.

No overage. No additional conversation is billed. Beyond the number of included conversations, a 20% margin remains available; conversations used within this margin are deducted from the included allowance for the following period, up to half of that allowance. Once the margin is exhausted, the assistant directs end users to the customer's contact form until the start of the next period. Voice conversations stop at the included number; the assistant then replies in writing, at no extra charge.

Billed overage. Beyond the number of included written conversations, each additional conversation is billed on a pay-as-you-go basis:

These overages are counted per billing period and charged in arrears, at the latest with the following instalment. The customer is notified when usage reaches 80% of the number of conversations included.

With this option, service is not interrupted when this number is reached: the customer's end users continue to be served, with no cap or suspension, additional conversations being billed at the rate above. Ubnbee LLC informs the customer of their usage and, where appropriate, suggests the higher plan.

Voice conversations. The number of included voice conversations is separate and appears in the same table. With the billed overage option, beyond that number each additional voice conversation is billed on a pay-as-you-go basis at 0.12€, regardless of the plan, up to three times the included number. Once this cap is reached, responses continue to be provided in writing for the remainder of the billing period, with no interruption of service and no further voice charge. Voice overages are counted and billed under the same conditions as written conversations.

First days of the subscription. By way of exception to the foregoing, no overage is billed during the first 14 days of the subscription: during this period, the billed overage option applies under the same conditions as the no overage option (20% margin, then end users are directed to the customer's contact form; voice conversations stop at the included number).

8. Term, renewal and cancellation

Monthly subscription. Taken out for one month, it renews automatically from month to month. The client may terminate it at any time, from their client area or by email to support@koaee.ai. Cancellation takes effect at the end of the current period; sums already paid for that period remain due.

Annual subscription. Taken out for twelve months, it renews automatically for the same duration unless cancelled. The client may terminate it at any time as of the next annual renewal date; cancellation during a period does not give rise to any refund, save for a breach by Ubnbee LLC.

Notice before renewal. The client is notified by email of the renewal of their annual subscription and of the option to object to it, no later than one month before the renewal date.

Effect of cancellation. Access to the services ceases at the end of the term. The client's data remains recoverable for thirty days from the end of the subscription, after which it is deleted.

9. Money-back guarantee

The refund covers the first subscription payment, including the showcase website option when it was taken out with it. Usage-based overage charges (Article 7) correspond to conversations already served: they remain due and are not covered by the guarantee.

The refund is made through Stripe, to the payment method used (Article 11). By way of exception to Article 8, the subscription ends as soon as the request is confirmed and the assistant stops responding. The customer's data remains retrievable for thirty days, after which it is deleted, under the conditions of Article 8.

The guarantee applies to the first subscription only, once per customer.

10. Right of withdrawal for consumer customers

The services are intended for professional use (Article 2). If the customer is nevertheless a consumer within the meaning of the preliminary article of the French Consumer Code, they have the right of withdrawal provided for in Articles L221-18 et seq. of that code: they may withdraw within fourteen days of the conclusion of the contract, without having to give reasons for their decision.

A customer who subscribes for the purposes of their professional activity has no right of withdrawal.

To exercise it, the customer sends, before the period expires, an unambiguous statement of their decision to withdraw, by email to support@koaee.ai. They may use the model form set out in the annex to these terms, but are not required to. Ubnbee LLC acknowledges receipt without delay.

Ubnbee LLC refunds the sums paid no later than fourteen days from the day on which it is informed of the decision to withdraw, using the same means of payment as the one used for the initial transaction, unless the customer expressly agrees to another means.

Where the customer has expressly requested that performance of the service begin before the end of the withdrawal period and then withdraws, they may be required to pay an amount proportionate to the service provided up to the communication of their decision, under the conditions of Article L221-25 of the French Consumer Code. The customer is not deemed to waive any of their rights.

The money-back guarantee of Article 9 applies to all customers, professionals and consumers alike.

This statutory right is in addition to the commercial money-back guarantee of Article 9: it does not replace it, and the guarantee does not restrict it.

11. Billing and payment

Payments are processed by Stripe, a payment services provider. Ubnbee LLC retains no bank card data.

Invoices are issued at each due date and made available in the customer area.

Payment default. If a payment fails, the customer is notified and has fourteen days to remedy the situation. Failing that, access to the services may be suspended automatically, without such suspension giving rise to any compensation or exempting the customer from paying the amounts due. Any sum unpaid at its due date automatically entails, without prior notice, late-payment penalties at a rate equal to three times the statutory interest rate, as well as a fixed recovery-costs indemnity of 40€, in accordance with Article L441-10 of the French Commercial Code.

12. Availability and support

Ubnbee LLC implements reasonable means to ensure the availability of the services. No guarantee of uninterrupted operation is given, unless otherwise stipulated in a quote. Scheduled maintenance interruptions are announced when foreseeable.

Support. Support is available by email at support@koaee.ai. For the Business plan, Ubnbee LLC undertakes to provide a first response within twenty-four business hours (Monday to Friday, 9 a.m. – 6 p.m., Paris time, excluding French public holidays). This commitment covers the first-response time, not the resolution time.

13. Nature of the artificial intelligence's responses

The assistants produce automatically generated responses, which may contain inaccuracies. They constitute neither professional advice — medical, legal, financial — nor a commitment on the part of Ubnbee LLC or the customer.

The customer remains responsible for the content, information and instructions they provide to their assistant, as well as for how they use it with their own users. It is their responsibility to verify that the information disseminated is accurate and up to date.

14. Customer obligations

The customer undertakes to provide accurate information and to keep it up to date; not to divert the services from their purpose, notably through attempts to extract system instructions, circumvent protections, or through massive automated requests; not to submit unlawful content or content for which they do not hold the necessary rights; not to resell access to the services without written agreement; and to inform their own users that they are conversing with an artificial intelligence system, in accordance with Article 50 of the European regulation on artificial intelligence.

15. Suspension and termination for breach

In the event of a serious breach by the customer of their obligations, Ubnbee LLC may suspend access after formal notice that has remained without effect for seven days, and terminate the contract as of right if the breach persists fifteen days after such formal notice.

In the event of a manifest and serious threat to the security of the services or of manifestly unlawful content, suspension may be immediate; the customer is notified without delay and invited to provide an explanation.

16. Liability

Ubnbee LLC is bound by an obligation of means. Its liability, on all grounds combined, is limited to the amount of the sums actually paid by the customer over the last twelve months preceding the triggering event.

Indirect damages are excluded, notably loss of revenue, of clientele, of data where it was otherwise backed up, and harm to image. These limitations apply neither in the event of gross negligence or wilful misconduct, nor of bodily injury, nor in cases where the law sets them aside.

17. Modification of terms and prices

These terms may be modified. The version applicable to an ongoing subscription is the one accepted at sign-up or at the last renewal.

Any substantial modification, as well as any price modification, is notified to the customer at least thirty days before it takes effect. A customer who refuses it may terminate free of charge before it takes effect; failing that, the modification becomes binding on them at the next renewal.

18. Intellectual property

The services, their code, their documentation and their content remain the property of Ubnbee LLC. Sign-up confers a personal, non-exclusive and non-transferable right of use, for the duration of the subscription.

The customer retains ownership of the data and content they provide. They grant Ubnbee LLC the right to host, reproduce and process it solely to the extent necessary to provide the services. The « koaee» trademark is registered with the INPI under number 5277383.

19. Personal data

The processing operations are described in the privacy policy. The respective obligations of the parties under the General Data Protection Regulation are set out in the data processing agreement concluded with the customer, which forms an integral part of the contract and is provided upon request at support@koaee.ai.

20. Force majeure

Neither party is liable for a breach resulting from an event of force majeure within the meaning of Article 1218 of the Civil Code. If the impediment exceeds sixty days, either party may terminate the contract by registered letter, without compensation.

21. Assignment, partial invalidity and forbearance

The contract may not be assigned by the customer without prior written agreement. Ubnbee LLC may assign the contract as part of a restructuring or business transfer operation, upon informing the customer.

If a provision is held to be void, the others remain applicable. Failing to invoke a breach does not amount to a waiver of the right to invoke it later.

22. Governing law and disputes

These terms are governed by French law.

In the event of a dispute, the parties will endeavour to find an amicable solution. Any claim may be addressed to support@koaee.ai; it will be answered within thirty days. Failing an amicable agreement, the dispute will be brought before the competent courts of Paris, without prejudice to the mandatory rules of jurisdiction.
